Setting Up IP/TV Content Manager
This chapter describes how to set up IP/TV Content Manager. Topics include:
•
Configuring Java Web Server

About Java Web Server
The Java Web Server is configured using the JavaServer Administration Tool. Any change you make in the Administration Tool is saved in properties files.
Follow these steps to access the Administration Tool:
Step 1
You can substitute localhost for <web-server> if you are running the browser on the same machine as the IP/TV Content Manager.
Step 2
Note
The following properties files are automatically modified during installation:
•
•
•
•
•
Configuring the Java Web Server Port
The Java Web Server uses port 80. If you have another Web server installed on the same machine, and did not change the default port during installation, you can configure Java Web Server to use a different port.
Follow these steps to configure the Java Web Server port:
Step 1
You can substitute localhost for <web-server> if you are running the browser on the same machine as the IP/TV Content Manager.
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
If you change the Java Web Server port number, you must reconfigure the IP/TV Content Manager port number in several places:
•
•
•
Shortcut to the IP/TV Content Manager
During installation, a shortcut to the IP/TV Content Manager is created and placed on the desktop of the IP/TV Content Manager host. The shortcut is set up with the default Java Web Server port number (or the number you specify when you install Java Web Server).
If you change the port number of the Java Web Server after installation, you need to modify the shortcut to the IP/TV Content Manager.
Follow these steps to change the default Web server port number:
Step 1
<web-server-root>\public_html\iptvfiles\launch.htm
Step 2
Step 3
Step 4
You may now use the shortcut to access the IP/TV Content Manager.
Configuring the RTSP Port
You rarely need to change the RTSP port number of the OnDemand Manager servlet. If it becomes necessary to change the port number, you can edit the following file:
<web-server-root>\classes\iptvodmgr.properties
and change the field iptvodmgr.server.port.
For your change to take effect, you must stop and restart the OnDemand Manager servlet.
The simplest way to stop and start a servlet is to stop and restart the Java Web Server using the following steps:
Step 1
Step 2
Step 3
Step 4
Alternatively, you can follow these steps to stop and restart only the OnDemand Manager servlet:
Step 1
You can substitute localhost for <web-server> if you are running the browser on the same machine as the IP/TV Content Manager.

Step 7
Accessing the IP/TV Content Manager
A computer used to access IP/TV Content Manager Version 3.0 must run Netscape Navigator 4.05 or 4.5x, or Microsoft Internet Explorer 4.x or 5.0. The browser must have Java and JavaScript enabled. Check the browser's Options or Preferences menu to be sure that these features are enabled.
These instructions assume that you are familiar with the Web, and have used a browser to access information sources on the Web. You should be familiar with the functions of your browser, and with concepts such as links. If not, we recommend that you read the documentation that was shipped with your browser, or explore the browser's help system.
To access the IP/TV Content Manager, go to the following URL:
http://<contentmanagerhost>/
where contentmanagerhost is the DNS name or IP address of the IP/TV Content Manager.
When you access the IP/TV Content Manager for the first time, store the URL in your Web browser's frequently visited sites list. The mechanism you use varies depending on which browser you use. Refer to your browser documentation or help system for more information.
When you access the IP/TV Content Manager, the first page that appears is the IP/TV Content Manager main page (see Figure 5-1).
Figure 5-1 IP/TV Content Manager Main Page
The IP/TV Content Manager main page contains the following links:
•
•
•

Setting IP/TV Content Manager Defaults and Preferences
The IP/TV Content Manager allows you to specify certain default parameter values, and to govern the level of information that is displayed on IP/TV Content Manager pages.
Follow these steps to set IP/TV Content Manager defaults and preferences:
Step 1
Step 2
See the "Multicast Addresses" section later in this chapter for more information about globally scoped and administratively scoped addresses and multicast range or Time-to-Live (TTL) values.
See the "Limiting How Far Your Programs Reach" section later in this chapter for recommendations on using administratively scoped addresses to limit how far your IP/TV programs reach across the network.
Figure 5-2 Multicast Addresses Section of the Preferences Page
Table 5-1 Multicast Address Options
Step 3
See the "Live Capture and File Format Reference" appendix for more information on the default video and audio formats and settings for various types of live-capture equipment.
Figure 5-3 Multimedia Sources Section of the Preferences Page
Table 5-2 Multimedia Sources Options
Step 4
Figure 5-4 Scheduled Program Management Section of the Preferences Page
Table 5-3 Scheduled Program Management Options
Delete Local Programs
Determines how long locally created program information will be saved by the IP/TV Content Manager. The default is 24 hours after the last run completes (minimum 0, maximum 720 hours).
Delete Announced Programs
Determines how long program announcements will be saved by the IP/TV Content Manager. By default, an announcement is deleted 24 hours after the last time it is received (minimum 0, maximum 720 hours).
Announce Local Programs
Determines whether this IP/TV Content Manager sends out announcements about its IP/TV programs to other IP/TV Content Managers on the network. The default is off. See the "Customer Sites Using Multiple IP/TV Content Managers" section later in this chapter for details.
Listen for Program Announcements
Determines whether this IP/TV Content Manager receives announcements from other IP/TV Content Managers.
Do Not Listen: If selected, the IP/TV Content Manager will not listen for other announcements.
Listen to Neighbors: If selected, the IP/TV Content Manager listens for announcements of programs that use the same administratively scoped addresses, or for programs that use global addresses if the server is defined on this IP/TV Content Manager.
List for Remote Announcements: If selected, the IP/TV Content Manager listens for announcements of programs that use globally scoped addresses.
Listen for All Announcements: If selected, the IP/TV Content Manager listens for all announcements.
Listen to these IP/TV Content Managers: Enter the DNS name or IP address of up to three other IP/TV Content Managers for whose announcements this IP/TV Content Manager will listen.
Step 5
Figure 5-5 Question, Recording, and File Transfer Management
Sections
Table 5-4 Question Management Options
Step 6
Table 5-5 Recording Management Options
Concurrent Per Server1
Determines the maximum number of concurrent recording sessions. The default is 4 (minimum 1, maximum 128).
Maximum Record Time2
Determines the maximum length (in hours) of a given recording. The default is 4 (minimum 1, maximum 24).
1 If you have a multihomed IP/TV Server, you must be careful not to exceed the concurrent recording limits. The IP/TV Content Manager can enforce the concurrent recording limits for a server with a single network interface, but cannot enforce them in the case of a multihomed host.
2 Recording files can consume a lot of disk space. You can conserve disk space by setting up procedures to delete or archive recordings that are no longer needed.
Step 7
See the "File Transfers" chapter for additional information on the File Transfer function.
Table 5-6
Maximum Concurrent FTPs1
The maximum number of concurrent FTP connections for each file transfer job. The default value is six concurrent connections per job. If the job has multiple sources specified, the connections are load-balanced across those source FTP servers that are responding.
Maximum Duration per FTP
The maximum amount of time that a file transfer job is allowed to run. When this amount of time has expired since the start of the file transfer job, the job is aborted and all open FTP connections are closed. The units are hours and the default value is 8.
Delete Completed FTP Jobs in
Determines how long the information about completed FTP jobs is saved in a Results page by the IP/TV Content Manager. The default is 24 hours (minimum 0 hours, maximum 720 hours).
1 The maximum number of concurrent FTPs per IP/TV Server limits the number of file transfers that can be ongoing at the same time, not the number of destination addresses you can specify when scheduling a file transfer. For example, if the limit is set to 6, and you schedule a server to transfer a file to 10 different destinations, the file transfers to the first 6 addresses in the list are performed concurrently, then as these are completed, the file transfers to the remaining 4 addresses begin. At no time will more than 6 file transfers be in progress, but all the transfers you schedule will complete eventually.
File Transfer Management Options
Step 8
Figure 5-6 Server Management Section of the Preferences Page
Table 5-7 Server Management Options
RTSP Server Port
Sets the default RTSP server port.The RTSP Port is the port number at which the IP/TV Server receives on-demand information from the IP/TV Content Manager, and must match the RTSP port configured at the server.
Capacity Per Server
Sets the capacity per server in kbps. Server capacity is the maximum amount of multimedia data that the server can output onto the network.
Capacity Per Cluster
Sets the capacity per server cluster in kbps.
Note
Total Content Manager Capacity
Sets the total capacity in kbps for all server clusters managed by this IP/TV Content Manager.
Idle IP/TV Viewer Timeout
Sets the number of minutes IP/TV Viewer can be paused or stopped before the connection with IP/TV Server is terminated. (Default is 30 minutes. Zero disables timeouts.)
Scheduled Reservation and OnDemand Non-preemption
Sets the number of minutes ahead of time that bandwidth is allocated for scheduled programs. An on-demand program will not be assigned to the server during the allocated time if the assignment would cause the capacity of the server to be exceeded when the scheduled program starts. On-demand programs that are active longer than the specified number of minutes may be preempted when the scheduled program starts if the server capacity would be exceeded. Setting this option to zero disables preemption but may cause the server capacity to be exceeded.
Step 9
Figure 5-7 Other Options Section of the Preferences Page
Table 5-8 Other Options
Proximity Group Priorities
Sets the number of server clusters available to Proximity Groups. The default is 5. See the "About Proximity Management" section later in this chapter for information about proximity groups.
Save Journaling Records for
Sets the number of days that journaling records are kept. The default is 0, which disables journaling. See the "Journaling" section in the "Administering the IP/TV Content Manager" chapter for information about journaling
Step 10
If the IP/TV Content Manager finds errors or omissions in the form, the Data Entry Errors page prompts you to return to the Preferences page to modify the information.
When you have finished correcting the errors, click Revise Preferences again to submit the corrections to the IP/TV Content Manager.
If the form is properly completed, you return automatically to the IP/TV Content Manager main page.
Multicast Addresses
When you set up a new channel, or a new program that is not assigned to a channel, the new channel or program is assigned the default multicast address type specified in the Preferences page.
All Class D IP addresses (224.0.0.0 through 239.255.255.255) are IP multicast addresses. Within Class D, three types of multicast address are available:
•
•
•
Link-Level Scoped IP Multicast Addresses
Packets with link-level scoped multicast addresses are configured in all routers as unforwardable. A program defined with a link-level scoped IP multicast address is not forwarded by any router, regardless of the multicast range defined for the program (see the "Globally Scoped IP Multicast Addresses" section later in this chapter for information about multicast ranges). We recommend that you do not use addresses in the link-level scoped address range when you set up programs.
Globally Scoped IP Multicast Addresses
Globally scoped multicast addresses use a mechanism called "multicast ranges" to limit how far across the intranet or Internet your program reaches.
The IP/TV Content Manager allows you to set the default multicast range, and to set the explicit values for each available range. The value for a range determines the TTL parameter for all channels or programs assigned that range.
The TTL parameter refers to the number of hops a packet can travel before the next router in the path declines to forward the packet. Table 5-9 lists the available multicast ranges and their default values.
Table 5-9 Multicast Range Default Values
Note
Administratively Scoped IP Multicast Addresses
The primary purposes of the administratively scoped IP multicast address range are:
•
•
Administratively scoped addressing relies on the routers in the network to limit how far across the intranet or Internet your programs are forwarded.
The IP/TV Content Manager is configured by default to use the range of administratively scoped addresses from 239.255.0.0 to 239.255.255.255, which is known as the IPV4 Local Scope. This scope has a fixed definition in RFC 2365 and is not to be subdivided. IP/TV Content Manager uses this range as the default range because the range should always exist wherever administrative scoping is used. However, we recommend that if you want to use administratively scoped addresses, you use instead some or all of the range 239.192.0.0 through 239.195.155.155 for the one or more zones you want to define. This is known as the IPV4 Organization Local Scope, and is intended for organizations to subdivide for their own purposes. Refer to RFC 2365 for detailed information about the use of IPV4 Local Scope and Organization Local Scope addresses.
Administrative scope zones may topologically overlap, but when they do, the address ranges must not intersect. (Topologically disjointed zones may reuse the same address range.) A separate IP/TV Content Manager must be used for each distinct address range because each IP/TV Content Manager only supports one range.
Follow these steps to configure administratively scoped multicast addresses:
Step 1
Step 2
Step 3
Administratively scoped IP multicast addresses are an important tool in limiting the impact of multimedia programs on your network.
Note
Limiting How Far Your Programs Reach
If you do not want your programs to be seen outside your site, use the following strategy:
•
•
•
IP/TV Security
IP/TV supports two levels of security:
•
•
Password Protection
The IP/TV Content Manager allows you to set passwords in two ways:
•
•
If a password is set (either for the channel or for the program), the user who wants to view a program must supply a matching password in order to view or subscribe to the program.
The password is always saved in encrypted form to preserve security.
Note
Note
Access Restrictions
IP/TV Content Manager allows you to limit write access to the IP/TV Content Manager to a browser running on a particular host name, address, or set of addresses.
The file <web-server-root>\cgi-bin\iptv\prefs\admin.prf sets the addresses that are allowed to access the IP/TV Content Manager. As shipped (see Figure 5-8), admin.prf gives full access to all users.
The file may be edited using a text-editing tool such as Notepad.
Figure 5-8 Sample admin.prf File
The pound sign (#) at the beginning of a line indicates that the line is a comment, not active code. To activate any of the lines, simply remove the pound sign and any adjacent spaces. The line of code you want to activate must begin at the left margin of the file.
If you modify admin.prf to limit access to the IP/TV Content Manager, and an unauthorized user attempts to change preferences or to modify or delete a program, channel, recording, or file transfer, the following message appears when the user submits the change to the IP/TV Content Manager:
You have read-only access to the IP/TV Content Manager. You are not authorized to make any modifications.Modifications to admin.prf take effect as soon as the changes are saved to disk.
About Proximity Management
Together, the Server Clusters page and the Proximity Groups page of the IP/TV Content Manager allow you to define the proximity of IP/TV Viewers to IP/TV Servers. Proximity management allows you to restrict IP/TV Viewers to receiving on-demand video only from specified server clusters and also allow you to balance on-demand loads among servers.
Servers and server clusters are defined in the Server Clusters pages of the IP/TV Content Manager. Each server is a member of a single cluster.
The IP/TV Content Manager is shipped with a cluster called Default. If you do not want to use clusters, assign all your servers to the Default cluster.
Note
A collection of subnets is defined as a proximity group. Any number of subnets can be defined within a single proximity group.
The assignment of proximity groups to server clusters is defined by the administrator, based on priority. Priority might be determined by physical distance, bandwidth capacity, network topology, or any other factor.
When a client requests an on-demand program, the OnDemand Manager verifies which proximity group the client belongs to, and obtains the list of server clusters that can be used to meet the client request. The OnDemand Manager then routes the IP/TV Viewer request to the cluster with the highest priority for that proximity group, and to the least busy server in that cluster.
If that cluster is unavailable, the OnDemand Manager then tries other clusters in order of their priority for that proximity group. The OnDemand Manager assigns the least busy server in the cluster to meet the client request, or, depending on how the system has been configured by the IP/TV administrator, may deny the request.
Note
Defining Servers and Server Clusters
The IP/TV Content Manager requires that you define all the machines that act as IP/TV Servers, and all other file servers that will be used for the transfer of media files.
Note
For scheduled program servers, you may define the servers in either of two ways:
•
•

The description is optional. However, it is useful to record information such as the location of the server and its capabilities (for example, a server that is used solely for live capture and has appropriate hardware such as a satellite feed or live-capture camera, a server in a specified department that is used to multicast all IP/TV programs for that department, or a server that is a multihomed host).
We recommend that you use the Description field to make it easier for IP/TV Content Manager administrators to select the appropriate server for a given program.

Multihomed Host Support
A multihomed host is a computer that has multiple network interfaces. IP/TV supports multihomed servers for scheduled multicast programs. You must define each interface as if it were a separate server in the IP/TV Content Manager. Then, when you create a program to be served by that machine, you must choose the correct server name.

Follow these steps to find the cluster for a given server:
Step 1
Step 2
Step 3
Managing Proximity Groups and Subnets
A proximity group is a collection of subnets. Any number of subnets can be defined within a single proximity group.
As shipped, the IP/TV Content Manager is configured with a default proximity group. The default proximity group contains a single subnet (0.0.0.0/0) named The World. The default proximity group gets its IP/TV programs from the default server cluster. With this initial configuration, all viewers in your network can view any program defined on any server in the default cluster.
If you prefer not to use proximity groups, you need not change this default configuration.
However, if you define new clusters, proximity groups, and subnets, your new definitions take precedence over the default configuration. Any viewers not in a proximity group you define remain in the default proximity group, and can view only those programs on the default server cluster.
If you want to tighten security, after setting up your own clusters, proximity groups, and subnets, delete the default proximity group and the default cluster. In this way, you can prevent any viewer not in a defined proximity group from viewing any IP/TV programs.
Note
Defining a Proximity Group
Follow these steps to define a proximity group:
Step 1
If no proximity groups have been defined, the page displays only the default proximity group, which includes all clients that belong to an unspecified network.
Step 2

Managing Channels
Channels are used only for scheduled programs and not for on-demand programs. The use of channels is optional. The IP/TV Content Manager allows you to set up programs that are not assigned to any channel.
If you decide to use channels as a way to organize IP/TV programs, you can define IP/TV channels in any of several ways. For example, you might choose one of the following schemes:
•
•
