Defining Programs
This chapter describes how to define programs in the IP/TV Control Server and connecting capture cards, and includes the following sections:
•
Defining an On-demand Program
•
Defining a Scheduled Program
•
Defining a Live-capture Program
If you have configured the servers correctly, after defining a sample scheduled or on-demand program, you will be able to watch the program in IP/TV Viewer (see
"").
Note
Both the Archive and Broadcast Servers can serve scheduled and on-demand programs. However, the Broadcast Server can only serve on-demand programs to a minimum number of viewers.
Defining an On-demand Program
To define an on-demand program, the IP/TV Control Server must communicate with the IP/TV 3400 Series Server, which will serve the on-demand file and and find all media files in the server's media root directory.
To verify communication between the IP/TV Control Server and the IP/TV 3400 Series Server that will serve the on-demand file, follow these steps:
Step 1
From your browser, access the IP/TV Control Server by entering the following URL:
http://controlserver/
where controlserver is the name of the Control Server on which the IP/TV Control Server is installed.
Step 2
On the IP/TV Control Server main page, click ServerWatch.
Step 3
Select a cluster and click Go.
Step 4
Confirm that the IP/TV 3400 Series Server you defined is listed and is in a managed state.
Note
It takes a few seconds for the IP/TV Control Server to connect with the servers. If the server is not listed, check to make sure you have correctly set up your Archive Server to be controlled by the IP/TV Control Server (see "").
To create a sample on-demand program, complete the following steps:
Step 1
From your browser, access the IP/TV Control Server by entering the following URL:
http://controlserver/
where controlserver is the name of the Control Server on which the IP/TV Control Server is installed.
Step 2
From the IP/TV Control Server main page, click OnDemand Programs.
The OnDemand Programs page appears.
Step 3
Click New Program on the task bar.
The New OnDemand Program page appears.
Step 4
Enter the following on-demand program information:
(a)
In the Program Name field, enter the name Sample Program.
(b)
Under Multimedia Information, click Select media file and select the media file sample.avi.
(c)
At the bottom of the page, enter your contact information.
(d)
Click Add OnDemand Program.
See "Managing OnDemand Programs" in Chapter 2, "Installing IP/TV Server"of the IP/TV Content Manager User Guide for detailed information.
Defining a Scheduled Program
To create a scheduled program, complete the following steps:
Step 1
From your browser, access the IP/TV Control Server by entering the following URL:
http://controlserver/
where controlserver is the name of the Control Server on which the IP/TV Control Server is installed.

Defining a Live-capture Program
This section contains information on defining a live-capture program, and discusses the following topics:
•
Overview
•
High Bit-rate Capture Settings
•
Medium Bit-rate Capture Settings
•
Low Bit-rate Capture Settings
•
Connecting the Broadcast Server Capture Cards
Overview
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 the Broadcast Server that will multicast the program. After defining a live-capture program, connect your audio and video outputs to the appropriate capture card inputs.
See "Live-capture Program Settings" in Chapter 2, "Installing IP/TV Server" of the IP/TV Content Manager User Guide for detailed information.
Note
A high bit-rate codec produces higher quality video. The level of quality you choose is determined by network capacity. Cisco recommends using the highest quality possible within the constraints of your network.
High Bit-rate Capture Settings
The IP/TV 3423 Server supports Full D1 MPEG2, and Half D1 MPEG2 encoding. The IP/TV 3415 Server supports Half D1 MPEG2 encoding. These systems are capable of high bit-rate encoding.
If you are setting up a live-capture program for high bit rate, follow these steps:

Connecting the Broadcast Server Capture Cards
After you define a live-capture program for high, medium, or low bit rate, connect the audio and video outputs of your device to the inputs of the appropriate capture card (see ).
•
If you have defined a high bit rate (MPEG2, MPEG2 Half D1, or MPEG1) program, connect your video source to the MPEG1/MPEG2 capture card. This capture card provides the highest video quality and consumes 500 kbps to 1.5 Mbps of bandwidth.
•
If you have defined any other type of program, connect your video source to the MPEG4/H.261 capture card. This capture card can be configured for either medium or low bit rate, and consumes 56 kbps to 768 kbps of bandwidth.
shows the audio and video inputs for the MPEG1/MPEG2 and MPEG4/H.261 capture cards.
Figure 5-1 Capture Card Audio and Video Inputs
To connect a capture card, complete the following steps:
Step 1
Connect your audio output to the audio input.
Step 2
Connect your video output to the video input appropriate for your device.
Step 3
Set the capture card settings for high, medium, or low bit rate.
