Managing Scheduled Programs

This chapter contains procedures for defining and managing scheduled programs. Once defined, the programs are listed in the Scheduled Programs window.

This chapter contains the following sections:

•Accessing a Scheduled Program

•Creating a Scheduled Program

•Reviewing a Scheduled Program

•Deleting a Scheduled Program

•Editing a Scheduled Program

•Duplicating a Scheduled Program

•Recording a Scheduled Program

•Using Question Manager

Accessing a Scheduled Program

In the IP/TV Program Manager main window, click the Scheduled Programs tab to display the Scheduled Programs window. (See Figure 6-1.)

Figure 6-1 Scheduled Programs Window

To sort the scheduled program list by program name, channel, server, or date and time, click one of the headings at the top of the list. The heading that you click becomes the new sorting criterion.

For each scheduled program listed in the Scheduled Programs window, the display includes the program name and description, the channel, the source server, and up to three dates and times at which the program is scheduled to be shown.

For each scheduled program, some or all of the following links are available:

•The Review link takes you to the Review Scheduled Program window (see the "Reviewing a Scheduled Program" section).

•The Delete link takes you to the Delete Scheduled Program window (see the "Deleting a Scheduled Program" section).

•The Edit link takes you to the Edit Scheduled Program window (see the "Editing a Scheduled Program" section). This link is not available for programs originating on other IP/TV Program Managers.

•The Duplicate link takes you to the Duplicate Scheduled Program window (see the "Duplicating a Scheduled Program" section). This link is not available for programs originating on other IP/TV Program Managers.

•The Retry ACNS Network Import link initiates a new attempt to import the scheduled program into the ACNS network. (This link is available only for programs inserted into the ACNS network.)

Creating a Scheduled Program

To create a new scheduled program using IP/TV Program Manager, follow these steps:

Step 1 In the IP/TV Program Manager main window, click the Scheduled Programs tab. The Scheduled Programs window appears. (See Figure 6-1.)

Step 2 In the Scheduled Programs window, click New Program in the banner bar. The New Scheduled Program Channel Selection Window appears. (See Figure 6-2.) If IP/TV is set up as part of an ACNS network, the New Scheduled Program window also displays the ACNS Network Information section. (See Figure 6-3.)

Figure 6-2 New Scheduled Program Channel Selection Window—Standalone IP/TV

Step 3 Choose a channel or choose None from the list. See the "Assigning Programs to Channels" section for more information about channels.

Step 4 Click a program type as follows:

•If the program that you want to create is a live-capture program, choose Basic Live Capture Program.

Note Cisco IP/TV software Release 5.2 and later versions provide failover support for the IP/TV Broadcast Server for the scheduled live-capture programs.To activate the failover support for the IP/TV Broadcast Server, configure failover servers for their different media streams as described in Step 19. (See Table 6-2.)

•If the program is intended to play a media file, choose Basic Media File Program.

•If you want to view all possible program options, choose Advanced Program (Show All Options).

Note If the program is to be inserted into an ACNS network, you must choose Advanced Program (Show All Options). In most other cases, either of the first two options is adequate to set up a program.

Figure 6-3 New Scheduled Program Window—IP/TV Integrated into an ACNS Network

Step 5 If you want to distribute the program over an ACNS network, follow Step 6 through Step 10. If you do not want to distribute the program over an ACNS network, go directly to Step 11.

Step 6 From the ACNS Network Information section of the New Scheduled Program window (see Figure 6-3), click Select Website to choose the ACNS network website.

The IP/TV: Browse Websites window appears, listing all the websites for which this IP/TV Program Manager is the origin server.

Note The ACNS Network Information section is displayed only if the IP/TV Program Manager is configured as a part of an ACNS network.

Step 7 Choose the website that has the channel to which you want to add the program.

Step 8 Click Select Channel.

The IP/TV: Browse Channels window appears. It lists all the live channels associated with the ACNS network website that you chose in Step 5.

Step 9 Choose the channel to which you want to add the program.

Step 10 Click Create Program to create a new scheduled program.

The New Scheduled Program window appears. (See Figure 6-4.) Depending on the program type that you chose in Step 4, some of the options shown may not appear. When IP/TV is integrated into an ACNS network, the New Scheduled Program window displays the name of the ACNS network channel with which the scheduled program is associated.

Figure 6-4 New Scheduled Program Window

Step 11 Enter the program name. Use a short name, such as Third-Quarter Sales Projections or New Employee Orientation. This field is mandatory; you must fill in this field.

Note IP/TV Program Manager permits a name up to 60 characters long. However, when the name of the program is displayed in IP/TV Viewer or on other IP/TV Program Manager windows, the name may be truncated to fit within the display area. For this reason, use short program names.

Step 12 In the Program Information section of the New Scheduled Program window, enter a description of the program in the Description field. This field allows you to enter a longer description of the program than the Program Name field permits. The maximum number of characters permitted in the Description field is 512.

Step 13 If there is a website that provides additional information about the program, you can enter the URL in the URL field.

If you enter a URL, a user watching this program on IP/TV Viewer can click the URL and go to the website.

Step 14 If the program contains copyrighted material, you can enter a copyright statement in the Copyright field.

Step 15 If the program is not assigned to an IP/TV channel, you can set a password for the program by entering the password in both the Password and the Confirm Password fields. Only users who know the password are able to view the program. If the program is assigned to an IP/TV channel, it inherits the password from the channel.

Note Passwords are applicable only in standalone IP/TV environments. The ACNS network does not support password-protected programs. If the ACNS network information has been entered in the ACNS Network Information section of the New Scheduled Program Window, IP/TV Program Manager does not display the password fields in the New Scheduled Program window.

The password protects the audio, video, and SlideCast streams in the program. If the program includes a web presentation stream, the web presentation stream is not protected.

Note Password-protected programs cannot be viewed by users of the Apple QuickTime player. Such programs can only be viewed using IP/TV Viewer.

Step 16 If you want to enable Question Manager for this program, check the Question Manager check box. See the "Using Question Manager" section for more information about the Question Manager function.

Step 17 If you do not want the program to be announced or to appear in program listings, but you do want to save the program information, check the Hide the Program from Viewer/SAP Announcements check box.

Step 18 In the Schedule section of the window, enter the program schedule. (See Figure 6-5.)

Table 6-1 describes the schedule options.

Figure 6-5 Schedule Section of the New Scheduled Program Window

Step 19 In the Multimedia Source Information section of the New Scheduled Program window, enter information about the program.

If the program is assigned to a channel, nearly all of these options are determined by the channel defaults. In this case, the only options that appear are the check boxes for video, audio, SlideCast, and web presentation.

The options that appear on the window also differ depending on whether you chose Basic Live Capture Program, Basic Media File Program, or Advanced Program in the New Scheduled Program window.

Figure 6-6 shows an example of the options for a basic live-capture program.

Figure 6-6 Multimedia Source Information—Live-Capture Program

Table 6-2 describes the options in the Multimedia Source Information section for a basic live-capture program.

Table 6-2 Multimedia Source Information Options

Field

Description

Preferred Video Format

Defines the preferred video format. This field defaults to the format specified in the Preferences window. Choices include H.261, Indeo, MPEG-1, MPEG-2 full D1, MPEG-2 half D1, ISO MPEG-4, Microsoft MPEG-4, and other Video for Windows codecs.

Compression Quality

Sets the H.261 compression quality level. Applies only to live-capture video compressed with the H.261 codec. The range is 1 through 10. The default value is 8.

Preferred Audio Format

Sets the format to be used for live-capture audio. This field defaults to the format specified in the Preferences window.

Video Frame Size For `MPEG4 - ISO' Format (Width x Height)

Sets the ISO MPEG-4 frame format to either predefined or customized dimensions in pixels (width x height). Unlike other codecs, the resolution cannot be changed in the IP/TV Server configuration. By default, the Preferred Audio Format option is set to AAC, 32000 Hz stereo.

Refer to the Cisco IP/TV Broadcast Server User Guide for ISO MPEG-4 minimum requirements.

Play Video

Defines whether the video portion of the file or live-capture stream is included in the program. The Enable QoS?¹ check box allows you to choose to enable QoS, if QoS is supported on your network.

Play Audio

Defines whether the audio portion of the file or live-capture stream is included in the program. The Enable QoS?1 check box allows you to choose to enable QoS, if QoS is supported on your network.

Play SlideCast

Defines whether the program includes a SlideCast portion in addition to video or audio. The Enable QoS?1 check box allows you to choose to enable QoS if QoS is supported on your network.

SlideCast playback has two choices of format available: H.261 and MPEG-4. Cisco IP/TV Release 5.2 and later releases support two resolutions: 640 x 480 and CIF (Common Intermediate Format 352 x 288) for ISO MPEG-4 encoding. It supports only CIF resolution for H.261 encoding. The default resolution for ISO MPEG-4 SlideCast is 640 x 480 and CIF is the default for H.261 for slide captures.

Note A scheduled program cannot contain both SlideCast and web presentation portions.

See Chapter 8, "Managing Online Presentations," for information on SlideCast.

Play Web Presentation

Defines whether the program is a web presentation in addition to video or audio.

For information on Web Presenter, see Chapter 8, "Managing Online Presentations."

Note The Play Web Presentation and related options are not available for programs that are inserted into an ACNS network.

Multicast content to client (required for ScreenCaster)²

Pushes the HTML pages and embedded graphics files of the web presentation to the client browser. If this option is checked, the pages are multicast to all viewers. If the option is unchecked, the browser of each viewer individually requests the HTML pages, and the server unicasts the pages to each requester, which adds the cumulative bandwidth required to deliver the HTML pages to the bandwidth required for the program.

Serve Over MPEG2 Transport

Enables MPEG-2 transport streaming. The Preferred Video Format option must be set to MPEG-2 full D1 or MPEG-2 half D1. The Preferred Audio Format option must be set to MPEG. The MPEG-2 transport option allows a program with a valid MPEG-2 transport file to be streamed as a single composite stream, instead of separate audio and video streams. MP2T is the standard format used in the cable industry.

AudioPID

Specifies the audio packet ID (PID) of the program. The range is 16 through 8190.

VideoPID

Specifies the video packet ID (VID) of the program. The range is 16 through 8190.

Share SlideCast with³

Specifies whether the program that you are defining includes the SlideCast stream from the program that you choose in the list.

Share Presentation with3

Specifies whether the program that you are defining includes the web presentation stream from the program that you choose in the list.

Audio/Video Bandwidth

Sets the audio/video bandwidth in kilobits per second (kbps). The default is 1150.

Note If the preferred video format of the program is ISO MPEG-4, you cannot change the bandwidth setting of the program directly. To change the bandwidth, you must change the video frame rate or the source video size.

Maximum Video Frame Rate

Sets the maximum number of frames per second for the video portion of the program. Applies only to MPEG live-capture streams and MPEG files. The default is 30.

Start Page URL (Optional)

Specifies the HTML page that the user goes to at the start of the presentation. It can be either a URL Internet address or the full pathname of an HTML file on the local hard drive of the server, for example, http://www.cisco.com or C:\BoardMtg\slide001.htm.

Audio/Video Server

Specifies the name or IP address of the IP/TV Server assigned to play the audio or video portions of the program. Choose a server from the list or enter the name of a new server.

Select Capture Card

Assigns the capture card port for live-capture programs. The drop-down list shows the available capture card ports depending on the codec selected. For MPEG-1 and MPEG-2, it lists 3 (1, 2, 3) ports. For other codecs, it lists 6 (1, 2, 3-1, 3-2, 3-3, 3-4) ports.

Select a Backup Server from this List

(Optional; mandatory if you want failover support for a live-capture program) Assigns a backup audio-video server for a live-capture program. Choose a server from the list. Make sure that the backup server has the same capture card settings as those of the primary IP/TV Server.

Select Capture Card (for Backup Server)

Assigns the capture card port for live-capture failover. The drop-down list shows the available capture card ports depending on the codec selected. For MPEG-1 and MPEG-2, 3 ports (1, 2, and 3) are available, whereas for other codecs, there are six available ports: 1, 2, 3-Port 1, 3-Port 2, 3-Port 3, and 3-Port 4.

SlideCast/Web Presentation Server

Specifies the name or IP address of the IP/TV Server assigned to play the SlideCast or web presentation. In the case of SlideCast, this server cannot be the same as the audio/video server unless audio, video, and SlideCast were all recorded to a media file. In the case of a web presentation, the server can be the same.

Select a backup server from this list

(Optional; mandatory if you want failover support for the live-capture program) Assigns a backup server for a SlideCast or web presentation stream of the live program. Choose a server from the drop-down list.

Note For a program containing audio, video, and SlideCast streams, you cannot assign the primary or backup audio video server as the backup server for SlideCast.

¹The Enable QoS option is not available for programs assigned to ACNS network channels.

²You must choose this option if the HTML pages are to be served by a server that is not configured as a web server or is not accessible to the browser of the user. This option must also be chosen for Web Presenter programs that multicast content captured with ScreenCaster, either live or from a previously recorded .mp4 file.

³The start and end time of the program that you are defining must be within the range of the program that contains the SlideCast or web presentation stream.

Figure 6-7 shows an example of the options for a basic media file program.

Figure 6-7 Multimedia Source Information—Media File Program

Table 6-3 describes those options in the Multimedia Source Information section for a basic media file.

Table 6-3 Multimedia Source Options—Basic Media File

Field

Description

Select media file

Specifies the media file to be associated with the program.

Click Select media file and choose a file from the list displayed in the Browse Media Files window.

When you choose a file, the Multimedia Source Information section is automatically populated with information about the file, such as length and bandwidth.

Note If you manually enter information about a file (such as filename, length, or bandwidth), IP/TV Program Manager cannot verify the information. You must enter the information accurately.

Play Once and Stop

Sets the program to play the specified file once and stop, even if the program is defined as having a longer duration than the file.

Loop for Program Duration

Sets the program to loop continuously until the interval specified by the program length has elapsed.

Play From Start to End

Sets the program to play the entire file from beginning to end.

Play .rtp Offset

Sets the program to play only the data between the first and the second offset. You must set both values. Applies only to Real-Time Transport Protocol (RTP) files.

Web Base URL (Optional)

Base portion of the URL that identifies the web server or local file path.

Server

Specifies the name or IP address of the IP/TV Server assigned to play the file. Choose a server from the list or enter the name of a new server.

Step 20 Enable Quality of Service (QoS) for improving transmission quality, if QoS is supported on your network.

Note The Enable QoS option is not available for programs that are inserted into an ACNS network.

The Enable QoS? check box to the right of the Play Video, Play Audio, and Play SlideCast check boxes lets you enable QoS using the Resource Reservation Protocol (RSVP). QoS provides superior transmission quality in networks with RSVP-enabled routers running under Windows 2000.

To view details regarding QoS, click QoS Details.

The QoS Details window appears. (See Figure 5-14.)

Table 6-4 lists the UDP port ranges used by IP/TV Program Manager for various types of data streams. If you decide to specify port numbers explicitly rather than letting IP/TV Program Manager assign them, you should choose even-numbered ports within these ranges.

Table 6-4 UDP Port Ranges

Type of Stream

Port Number Range

Audio

16,384 through 32,766

Web presentation

32,768 through 49,150

Video or SlideCast

49,152 through 65,534

Step 21 In the ACNS Network Delivery Mode section, choose the mode of content delivery over the ACNS network and the mode of stream delivery to the root Content Engine over the ACNS network. (See Figure 6-8). The delivery of a live stream over the ACNS network behaves differently depending on whether you choose Multicast or Unicast in the stream delivery section to the root Content Engine. (See Table 6-5)

Note The ACNS Network Delivery Mode section is available only for programs that are assigned to an ACNS network channel. This section is not displayed if ACNS network channel information has not been entered for the program.

Note To use the failover support for the root Content Engine, select Multicast mode in the Stream Delivery Section and ensure that the Cisco IP/TV Broadcast Server, the root Content Engine, and the backup Content Engine belong to the same multicast cloud.

Figure 6-8 ACNS Network Delivery Mode

Table 6-5 ACNS Network Program Delivery Mode Options

ACNS Network Delivery Mode

Stream Delivery to the Root Content Engine

Multicast

Unicast

Live Multicast and Live Split

The root Content Engine receives the program as multicast streams from the IP/TV Broadcast Server. This option facilitates a failover support to the root Content Engine.

The root Content Engine then unicasts the streams to the edge Content Engines that are subscribed to the channel with which the program is associated. The edge Content Engines then multicasts or unicasts the stream to the clients that are connected to them.

Note To use the failover support, ensure that Cisco IP/TV Broadcast Server, the root Content Engine, and a backup Content Engine are setup in the same multicast cloud.

The root Content Engine receives the program as unicast streams from IP/TV Broadcast Server.

The root Content Engine then multicasts the streams to the clients that are connected in the same multicast cloud and also unicasts them to the edge Content Engines that are subscribed to the channel with which the program is associated. The edge Content Engines then multicast or unicast the stream to the clients that are connected to them.

Note This option does not support failover to the root Content Engine.

Live Split Only

The root Content Engine receives the program as multicast streams from IP/TV Broadcast Server and then unicasts the streams to the edge Content Engines subscribed to the channel. The edge Content Engines unicast the streams to clients on a per-request basis.

This option supports failover for the root Content Engine.

Note To use the failover support, ensure that Cisco IP/TV Broadcast Server, the root Content Engine, and a backup Content Engine are set up in the same multicast cloud.

The root Content Engine receives the program as unicast streams from IP/TV Broadcast Server and then unicasts the streams to the edge Content Engines subscribed to the channel. The edge Content Engines unicast the streams to clients on a per-request basis.

Note This option does not support failover to the root Content Engine.

Step 22 In the Multimedia Address Information section of the New Scheduled Program window, enter information about the program.

The options that appear in the window differ depending on whether you chose Basic Live Capture Program, Basic Media File Program, or Advanced Program in the New Scheduled Program window. Most of these options also depend on whether the corresponding global option to allow them to be selected is enabled or not (in the Preferences window).

Note If the program is to be delivered over an ACNS network using live multicast mode, you must use the same multicast IP address for audio, video, and SlideCast streams.

See Chapter 3, "Setting Up IP/TV Program Manager," for source-specific multicast (SSM) and multicast address information.

Figure 6-9 shows an example of the Multimedia Address Information options for a basic live-capture program.

Figure 6-9 Multimedia Address Information— Basic Live-Capture Program

Table 6-6 describes the options in the Multimedia Address Information section for a basic live-capture program.

Table 6-6 Multimedia Address Information—Basic Live-Capture Program

Field

Description

Use SmallCast (Forward to Source Server's Unicast List)

Determines whether the program will be forwarded to unicast addresses. The default is off (no SmallCasting is allowed). This option is not available unless the option to allow SmallCast is enabled globally (in the Preferences window) and alternatively, this option is not available for a program distributed over the ACNS network.¹

SmallCast Only; Do Not Multicast on the Source Server

Suppresses multicast from IP/TV Server. IP/TV Server only sends out unicast streams. This option is not available unless the option to allow SmallCast is enabled globally (in the Preferences window) and alternatively, this option is also not available for a program distributed over the ACNS network.1

RTCP Feedback Suppression

Suppresses interactive responses from any viewer that is RTP/RTCP compliant. The three options are as follows:

•Suppress multicast RTCP feedback—Suppresses only multicast RTCP feedback; unicast feedback is allowed.

•Suppress all kinds of RTCP feedback—Suppresses both unicast and multicast feedback.

•Do not suppress any RTCP feedback—Allows both unicast and multicast feedback.

Capture Live MPEG Data for Recording to File; Do Not Multicast

Records streams sent from the video capture card of IP/TV Server to disk. No multicast streaming is performed. This option is not applicable to a media file program and alternatively, this option is also not available for a program distributed over the ACNS network.1

¹A program distributed over a ACNS network supports failover and fallback to the Content Engine.

Figure 6-10 shows an example of the Multimedia Address Information options for an advanced program.

Figure 6-10 Multimedia Address Information—Advanced Program

Table 6-7 describes the Multimedia Address Information options for an advanced program.

Table 6-7 Multimedia Address Information—Advanced Program

Field

Description

Select Global Scoped Addresses¹

Determines whether globally scoped addresses will be used for the program. This option is not available unless the option to allow administratively scoped addresses is enabled globally (in the Preferences window).

Select Addresses Manually¹

Allows the user to specify multimedia address information for the program. This option is not available unless the option to allow modifications of IP addresses, UDP ports, and multicast range is enabled globally (in the Preferences window).

Multicast TTL Range¹

Sets the multicast range for the program.

Video IP Address¹^{, ²}

Defines the video IP address for the program.

Video UDP Port¹

Defines the video UDP port for the program. See Table 6-4 for UDP port ranges.

Audio IP Address¹^,²

Defines the audio IP address for the program.

Audio UDP Port¹

Defines the audio UDP port for the program. See Table 6-4 for UDP port ranges.

SlideCast/Presentation IP Address¹^,²

Defines the IP address for the SlideCast or web presentation portion of the program.

SlideCast/Presentation UDP Port¹

Defines the UDP port for the SlideCast or web presentation portion of the program. See Table 6-4 for UDP port ranges.

Use SSM¹

Enables SSM for the program when multimedia addresses are configured using the Use these Addresses option.

¹This option is available only if the Allow modification of IP addresses, UDP ports, and Multicast Range check box is checked in the Preferences window.

²If the program is to be delivered over an ANCS network using live multicast mode, you must use the same multicast IP addresses for audio, video, and SlideCast streams.

Step 23 In the Contact section of the New Program window, enter the name of a person for users to contact for questions about the program.

Step 24 Click Create Program to send the form to IP/TV Program Manager.

If IP/TV Program Manager finds errors or omissions in the form, the Data Entry Errors window prompts you to return to the New Program window to modify the information.

When you have finished correcting the errors, click Create Program again to submit the corrections to IP/TV Program Manager.

If the form is properly completed, you return automatically to the Scheduled Programs window.

Step 25 If you want to undo the changes that you made, click Reset to restore the original settings.

Assigning Programs to Channels

IP/TV Program Manager allows you to set up programs that are not assigned to any channel. However, channels offer a few benefits:

•Each channel has many default characteristics. If you assign a new program to a channel, the program automatically receives the defaults.

However, if you set up a program that is not assigned to a channel, you must enter much more information about the program.

For example, each channel has a unique set of multicast addresses and UDP port numbers.

All programs assigned to that channel automatically use the same addresses and port numbers, so you do not need to remember which addresses (or address ranges) to assign to the program.

•In the IP/TV Program Manager main window, programs can be sorted by channel. In a busy network with many programs having multiple repeat showings, the list of programs can become very long. You can assign programs to channels as one way to make the list easier to navigate and programs easier to locate.

For more information on channels, see the "Programs and Channels" section.

Program Schedule Options

For any live-capture session, you should set the start time a little earlier and the end time much later than you expect the live-capture session to start and end. Setting the start and end times allows for any slip in the actual start or end of the event. When a recording is made, "dead air" at the beginning and end of the session is not saved in the file.

When you decide how to schedule a program, you first must determine whether the program is a continuous or noncontinuous program:

•A continuous program is "on the air" at all times. One analogy is a 24-hour news station on cable television. The news program is always on but has no explicit start and stop time the way a network TV program does.

If you define a program as continuous, and assign it to a channel, you can still define noncontinuous programs on that channel. The noncontinuous programs simply overlap the continuous program (but are not allowed to overlap each other). If the continuous program is a prerecorded file, the continuous program restarts from the beginning when the noncontinuous program has finished. Noncontinuous programs must be multicast from the same server as the continuous program that they overlap.

An example of a continuous program that has a noncontinuous program overlapping it is a 24-hour news service. The news program is always on, and users can tune in whenever they want to get a news update. Suppose that the financial news is always discussed for a half-hour starting at 3:00 p.m., and some users want to subscribe to the financial news so that IP/TV automatically launches the program for them. You can define a noncontinuous program that begins at 3:00 p.m. and runs for 30 minutes. This noncontinuous program is a subset of the 24-hour news program and overlaps it for that 30-minute interval.

•A noncontinuous program has a start and stop time for its first showing and possibly one or more repeat showings.

For noncontinuous programs only, you can do one of the following tasks:

•Set up a simple repeat schedule in which the program repeats after the number of minutes, hours, or days that you specify. For example, the program can repeat every 24 hours or every 7 days. Some intervals may fall at hours or on days when there are no IP/TV Viewer users onsite to watch the program.

•Set up a more complex repeat schedule. For example, you can set the program to repeat weekly on Mondays at 0900, Wednesdays at 1600, and Fridays at 1200.

Note If you define weekly or biweekly repeats, the "Play Program once on" date and time must be on a repeated date and time. For example, if the program starts on a Monday at 1400, one of the repeats must be Monday at 1400.

These two choices are either/or choices. You cannot combine them for the same program. If your program needs a repeat schedule with more complexity, set as much of the schedule as you can in this window. Once the program is submitted to IP/TV Program Manager and you have returned to the main window, click the Duplicate link for that program to create a duplicate of the program. You can set the remaining repeat schedule in the duplicate program. See the "Duplicating a Scheduled Program" section for tips on using the Duplicate Scheduled Program window.

Live-Capture Program Settings

When you define a live-capture program, you must set the video format, audio format, data rate, and frame rate parameters to values appropriate to the video capture card and codec (compression/decompression) used by IP/TV Server that will capture and multicast the program. Refer to Appendix A in the Cisco IP/TV Broadcast Server User Guide for recommended settings for the most common codecs.

Playing Media Clips Before a Live Event

This feature helps you to set up a program of media clips to play before the broadcast of a live event. This program has the same attributes as the live event and plays before the scheduled broadcast of the live event. The program starts playing at the time set by you and stops when the live event starts playing. The live event plays in the same window as the program of media clips. You can use this feature to broadcast related programs and information and to keep the viewers tuned to the scheduled broadcast of the live event.

The feature also helps you to verify that users can view the scheduled broadcast. If the users can view the program of media clips with no difficulty, then they will also be able to receive the broadcast of the live event. Playback of media clips before a scheduled event is implemented using the channel concept. For more information about channels, see the "Programs and Channels" section and "Assigning Programs to Channels" section.

To set up playback of media files before a live event, follow these steps:

Step 1 Create a channel that has the same attributes as the live event.

a. In the banner bar of the Scheduled Programs window, click Channels.

b. In the Channels window, click New Channel.

c. Enter a name and then set the attributes to match those of the live program.

d. Click Create Channel.

Note Enter the name of the Channel, Channel Information's Description, the Administrator's Name, and the Administrator's e-mail Id. These fields are mandatory, you must fill these fields to create a channel.

Step 2 Go to the New Scheduled Program window.

Step 3 Choose the channel from the drop-down list.

Step 4 Create a new program.

Step 5 Set the end time of the program to be not later than the start time of the live event.

Step 6 Create a live program in the same channel.

Note Check the Hide program from viewers/SAP announcements check box in the New Program window when creating the live event to prevent the live program from being listed in the Scheduled program list.

Reviewing a Scheduled Program

To review a scheduled program, follow these steps:

Step 1 In the Scheduled Programs window, click Review for the program that you want to be reviewed. The Review Scheduled Programs window appears. (See Figure 6-11.)

Step 6 Click Duplicate Program at the bottom of the window to save the changes.

Recording a Scheduled Program

IP/TV allows you to record a scheduled IP/TV program and save it in a media file on the local disk of IP/TV Server. This feature is usually used to record content that is acquired through live capture for playback at a later time.

IP/TV provides two types of recording—MOV recording and native recording. MOV recording saves the program in a .mov file. Native recording saves the program as an .mpg file or .mp4 file.

Note MPEG and MP4 recording can be done only on the encoding server that is on the same IP/TV Server where the live capture is running. Use MOV recording for remote recording.

Cisco IP/TV Release 5.1 and later versions support the following audio and video codecs for MOV recording:

Audio: MPEG, mu-law, Audio Video Interleaved (AVI), Global System for Mobile Communication (GSM), Digital Video Interactive (DVI), Advanced Audio Coding (AAC), 8-bit linear, and 16-bit linear

Video: H.261, MPEG-1, MPEG-2, and MPEG-4

Note Cisco IP/TV Release 5.1.3 and later releases support MOV recording of MPEG-2 Transport (MP2T) streams.

Note Cisco IP/TV Release 5.1.3 and later releases support local playback of IP/TV-recorded MP4 files using the QuickTime Player. However, the support is limited to MP4 files containing AAC audio; QuickTime does not support playback of MP4 files with MP3 audio.

The following factors determine which file format is used to save the live-capture content from a native recording:

•If the live-capture data stream is MPEG-1 or MPEG-2, and if the same server is used both to capture the data and to record it to a file, the file format must be MPEG (that is, the file must have an extension of .mpg).

•If the live-capture data stream is ISO MPEG-4, the file format must be MP4 (that is, the file must have an extension of .mp4).

To display a list of all scheduled recordings, click the Recordings tab in the IP/TV Program Manager main window. The Recordings window is shown in Figure 6-15.

Figure 6-15 Recordings Window

For each recording, the information displayed includes the name and description of the program to be recorded, the name of the source server, and up to three dates and times at which the program is scheduled to be recorded.

For each recording, the following links are available:

•The Review link takes you to the Review Recording window (see the "Reviewing a Recording" section).

•The Delete link takes you to the Delete Recording window (see the "Deleting a Recording" section).

•The Edit link takes you to the Edit Recording window (see the "Editing a Recording" section).

Scheduling a Recording

These sections describes the procedure for setting up a recording:

•Creating a multimedia data stream for the recording on page 6-42

•Setting up the recording on page 6-43

Creating a Multimedia Data Stream for the Recording

If the content that you want to record is not already defined as a program, see the "Creating a Scheduled Program" section for instructions on setting up a new program.

If you want to record an existing program, you do not need to define a new program before you can record it, because it is already defined in IP/TV Program Manager.

In addition, consider the following points:

•Set the start and end time in the Schedule section of the New Scheduled Program window.

For any live-capture session, you should set the start time a little earlier and the end time much later than you expect the live-capture session to start and end. Setting the start and end times allows for any slip in the actual start or end of the event. When a recording is made, "dead air" at the beginning and end of the session is not saved in the file.

Note If you are using media streams from two servers for a recording, you must make sure that both servers have the same time settings. If the clocks on the servers are not synchronized, your program also may show synchronization problems, such as media streams losing synchronization. To synchronize clock settings on different devices running Microsoft Windows, use authoritative time server (ATS) settings in Windows. For more information, refer to the Microsoft Support website.

•In the Multimedia Source Information section, check the Play check boxes for Video, Audio, SlideCast, and Web Presentation as appropriate for the content to be recorded.

Note Web presentation programs can be recorded when they are part of a program that contains ISO MPEG-4 video and MP3 or AAC audio. The web presentation server must also be the same as the audio and video server.

•In the Multimedia Address section, choose the servers that capture the data. In addition, verify the status of the Capture Live MPEG Data for Recording to File; Do not check Multicast check box.

–If you are recording the program but not multicasting it simultaneously, check the check box.

–If you are recording the program and also want to simultaneously multicast it, uncheck the check box.

Setting Up the Recording

To set up a new recording, follow these steps:

Step 1 In the Recordings window, click New Recording in the banner bar. The New Recording Program Selection window appears. (See Figure 6-16.)

Figure 6-16 New Recording Program Selection Window

Step 2 Choose an IP/TV program or an MBone session in the list and click Create Recording. The New Recording window displays information about the program that you chose. (See Figure 6-17.)

Figure 6-17 New Recording Window

Step 3 Review the Program Information section of the window to be sure that you have chosen the correct program.

Step 4 In the Name field, enter a name for the recording, or accept the name supplied by IP/TV Program Manager. The default name is the same as the original program name.

Note IP/TV Program Manager permits a name up to 60 characters long. However, when the name of the program is displayed in IP/TV Viewer or on other IP/TV Program Manager window, the name may be truncated to fit within the display area. For this reason, you should use short program names.

Step 5 In the Recording Information section, enter a description of the recording or accept the description supplied by IP/TV Program Manager. The default description is the same as the original program description. The maximum number of characters permitted in the description field is 512.

Step 6 In the Recording Schedule section (see Figure 6-18), the default recording schedule is the next showing of the program that ends after the current date and time, plus any repeats scheduled for the program.

Accept the default schedule, or override it by changing the information in any of the editable fields.

Figure 6-18 Recording Schedule Section of the New Recording Window

Step 7 In the Recording Instructions section (see Figure 6-19), specify whether the recording includes the video and audio portions of the program. By default, all the data streams included in the program are enabled for the recording.

Figure 6-19 Recording Instructions Section of the New Recording Window

Step 8 Enter the full pathname of the file in which the recording is to be stored.

IP/TV assigns the file extension depending on the codec used. There are three different types of file extensions used for IP/TV recordings: .mov, .mpg, or .mp4. MOV files are created if the MOV recording option is selected. The MPG file format is used for local recording of live MPEG-1 or MPEG-2 data streams. The MP4 file format is used for local recording of ISO MPEG-4 data streams.The MP4 file format is also used to record a web presentation stream if the web presentation stream is part of a live program with ISO MPEG-4 video. However, this process is possible only when the audio and video server is the same as the Web Presenter server.

Step 9 Choose the type of recording that you want to set up. If you want the program to be recorded in MPEG or MP4 file formats, click Native Recording. For recording in the MOV format, click Mov Recording. For details on supported codecs for different types of recording, refer to the Cisco IP/TV Broadcast Server User Guide.

Step 10 Specify whether an existing file by the same name should be overwritten.

Check the Do not overwrite existing file check box so that unique filenames are generated to prevent the first recording from being overwritten by a later recording of the same program. If you choose not to overwrite repeated recordings, these files occupy a great deal of disk space and may quickly fill the server disk drive.

Step 11 Choose a server from the drop-down list or enter the name of a new server. This name must be the name of the server that performs the recording and stores the file on its local disk drive. The live-capture server or the server serving the program cannot be the same as the recording server unless you are recording an MPEG-1 or MPEG-2 data stream to an MPG file.

Step 12 Choose a second sever for redundant recording from the drop-down list. When you choose a second server for recording, both the servers record the stream and save it on their local disks. Even if one server fails, you can use the file from the other server for future programs.

Step 13 In the Contact section, (see Figure 6-20), enter the name, telephone number, and e-mail address of a person for users to contact with questions about the recording.

Figure 6-20 Contact Information Section of the New Recording Window

Step 14 Click Create Recording at the bottom of the New Recording window to send the form to IP/TV Program Manager.

If IP/TV Program Manager finds errors or omissions in the form, the Data Entry Errors window prompts you to return to the New Recording window to modify the information.

When you have finished correcting the errors, click Create Recording again to submit the corrections to IP/TV Program Manager. If the form is properly completed, you return automatically to the Recordings window.

IP/TV Server automatically records the program to the specified file according to the schedule that you set. Refer to the Cisco IP/TV Broadcast Server User Guide for information on administering IP/TV Server.

As soon as the recording session is completed, you can create a scheduled or on-demand program using this file.

If the form is properly completed, you return automatically to the Recordings window.

Setting Up Failover Support for an IP/TV Recording

Cisco IP/TV Release 5.2 and later releases allow you to configure failover support for recordings of live-capture programs that have streaming failover support enabled.

To create a recording with failover support, follow these steps:

Step 1 From the Recordings window of IP/TV Program Manager, click New Recording.

Step 2 In the New Recordings window, enter the necessary information as described in Step 1 through Step 11 of the "Setting Up the Recording" section.

Step 3 Choose a backup IP/TV Broadcast Server from the Select a second server (for redundant recording) drop-down list. (See Figure 6-21.)

Note The Select a second server (for redundant recording) drop-down list is available only when you create a recording for a live-capture program that has failover enabled for streaming.

Figure 6-21 Recording Instructions Section of the New Recording Window

Step 4 Complete Step 12 through Step 14 of the "Setting Up the Recording" section.

Both primary and secondary IP/TV Broadcast Severs record the media streams and create identical files. If you encounter a problem on one of the servers, you can use the file on the other IP/TV Broadcast Server.

Using Question Manager

Question Manager is a text-only feedback mechanism that allows users to submit questions to the moderator of a scheduled program. The moderator can display the questions that apply to the program, sort the questions, answer the questions as part of the presentation that is being shown, export the questions to be stored or manipulated in an external spreadsheet or database application, and delete the questions after the program is complete.

Question Manager is useful for environments such as distance learning and training. It allows remote users to participate in the question and answer portion of the presentation.

The Question Manager function applies to scheduled programs, but not to on-demand programs.

Note This participation is not fully interactive. Question Manager is a unidirectional tool; it sends questions to the program moderator, but does not return answers to the user. Answers must be provided as part of the program content.

Enabling Question Manager

Before a user can submit questions about an IP/TV program to the program moderator, or before an administrator can moderate a program, Question Manager must be enabled for that program.

To enable Question Manager for a scheduled program, check the Enable Question Manager check box in the New Scheduled Program, Edit Scheduled Program, or Duplicate Scheduled Program window. An example of the New Scheduled Program window is shown in Figure 6-4.

Accessing Question Manager

Viewers of IP/TV programs can access Question Manager in different ways, depending on the viewer application they are using. Table 6-8 describes the various methods of accessing Question Manager.

If no username or e-mail has been provided, the moderator receives the question from Anonymous.

If changes are required in the "From" information, click in the From field and enter the changed information. When you click Submit, the question is sent to the Question Manager moderator. Questions can be submitted even before the program begins.

Moderating an IP/TV Program

To use the Question Manager moderator, your web browser must have Java support enabled.

To moderate a Question Manager-enabled program, follow these steps:

Step 1 In the Scheduled Programs window, click Question Manager in the banner bar.

You can also moderate a Question Manager-enabled program by entering the following URL:

http://Programmanagerhost/iptvfiles/qmselect.htm

where Programmanagerhost is the DNS name or IP address of the IP/TV Program Manager managing the program.

The Moderator Program Selection window appears. (See Figure 6-23.)

Step 2 Choose a program from the drop-down list. As soon as you choose a program, information about the program is displayed in the Program Information section of the window.

Step 3 Click Start the Moderator to begin moderating the selected program. The Question Manager Moderator window appears. (See Figure 6-24.)

Figure 6-23 Question Manager Moderator Program Selection Window

Figure 6-24 Question Manager Moderator Window

The Question Manager Moderator window displays the list of outstanding questions for the program. Initially, the list is displayed in the order in which the questions were received.

For each question, the display includes the status of the question, the name of the person who submitted the question, the date and time the question was submitted, and the Subject field from the Question Manager dialog box that the user filled in.

Sorting the Question List

To sort the question list by status, name, date and time, or subject, click the column heading to be used as a sort criterion. As new questions are submitted, they are added to the list and sorted according to the current sort criterion.

Displaying the Full Text of a Question

To display the full text of a question (that is, the text entered in the question box on the Question Manager dialog box of the user), choose the question by clicking anywhere in that row.

Changing the Status of a Question

Initially, every question has the status "Q," indicating that the question has not been answered. Questions may be answered in several ways. None of these ways results in feedback to the person who submitted the question other than through the program content.

During the program, if the program content addresses a user question, the moderator can change the status to "A," to mean "answered.". If the program includes a question and answer period, and the question is answered by the presenter, the moderator can change the question status to "A"

To change the status of a question, choose the question and click Answered. The status field for that question changes from "Q" to "A."

If the list of questions is long and many questions have been answered, the moderator can delete answered questions from the list by choosing each answered question and clicking Delete.

Deleted questions disappear from the question list of the moderator, but IP/TV Program Manager does not purge them completely until it deletes the program.

To purge deleted questions before IP/TV Program Manager deletes the program, the moderator can click Purge All Deleted.

Displaying Questions in Table Form

At any time, the moderator can display the questions for the program in table form by clicking Show All. The List All Questions window appears. (See Figure 6-25.) You can use this form to print out and give to the program presenter, so the presenter can answer the questions during the question and answer portion of the presentation.

The list displayed in the List All Questions window includes all questions for the program being moderated and whether their status is asked, answered, or deleted.
