Program Examples

3 Chapter

This chapter contains examples showing how to define the most common types of IP/TV programs. Each example includes a scenario that describes what kind of program is being defined, and the criteria used to select options. When default values are acceptable, this is indicated in the text.

Sample Network

The examples in the following sections are based on the sample network described here:

• The main network is located at the corporate headquarters of Zycorp, Inc., in San Jose, California. About 100 IP/TV Viewer users are on this network, and one IP/TV Content Manager. The two IP/TV Servers on the network serve media files, whether scheduled or on-demand. In addition, one of the IP/TV Servers (Server A) is equipped with live-capture hardware.

• A second network is located in Zycorp's sales office in Boston. This network is connected to the main network by a T1 leased line. About ten IP/TV Viewer users are on this network, along with one IP/TV Content Manager and one IP/TV Server. The IP/TV Server serves both scheduled and on-demand programs.

• A third network is located in Zycorp's sales office in Mexico City. This network can be reached from the main network via the Internet. About five IP/TV Viewer users are on this network, and one IP/TV Server. There is no IP/TV Content Manager; the IP/TV Server and all IP/TV Viewers are configured to get their program information from the IP/TV Content Manager in San Jose.

• A fourth network is located in Zycorp's manufacturing plant in Singapore. This network can be reached from the main network via the Internet. About 50 IP/TV Viewer users are on this network, along with one IP/TV Content Manager, and one IP/TV Server.

Figure 3-1 shows all of the IP/TV Servers and IP/TV Content Managers on each network, but only one sample PC running IP/TV Viewer on each network.

Sample OnDemand Category

Table 3-1 lists the settings chosen by the IP/TV administrator to set up an OnDemand category in the IP/TV Content Manager on Zycorp's headquarters network.

Sample OnDemand Program

Table 3-2 lists the settings chosen by the IP/TV administrator to set up an on-demand program in the IP/TV Content Manager on Zycorp's headquarters network and autodistribute the program to a second server.

This program is defined within the OnDemand category Instructional Videos (see Table 3-1).

The program is a 30-minute video summary of the information covered in the Employee Handbook. The media file, which initially resides only on Server B in San Jose, will be automatically distributed to Server A. Autodistributing the media file allows IP/TV Content Manager to balance the load of requests for the program.

Sample Scheduled Program to Play a Media File

Table 3-3 lists the settings chosen by the IP/TV Administrator when setting up the simplest type of scheduled program. The program is a 1-hour film describing the 401(k) retirement plan available to all Zycorp employees located in San Jose and Boston. It does not apply to the employees in Mexico City or Singapore.

Table 3-3 lists all the parameters in the New Program page and gives a recommended setting for each parameter.

Sample Scheduled Live-Capture Program

Table 3-4 lists the settings chosen by the IP/TV Administrator when setting up a scheduled program for live-capture content.

Sample SmallCast Program

The Zycorp CEO plans to videotape an important 45-minute announcement to all employees. The taping will take place at 10:00 A.M. in San Jose, and the CEO wants the program to play simultaneously in Boston and Mexico City.

Table 3-5 lists the settings chosen by the IP/TV Administrator when setting up a program to accomplish this using SmallCast.

The capture server in San Jose must be configured to be able to SmallCast to the IP/TV Server in Mexico City. Refer to Chapter 5 in the IP/TV Administration and Configuration Guide for information on defining servers.

Sample Recording

Given the differences in local time between San Jose and Singapore, the "Sample SmallCast Program" example would not be a practical way to send the corporate announcement to users in Singapore. The original program was multicast during working hours in San Jose, which is the middle of the night in Singapore.

A better strategy would be to follow these steps:

Step 1 Record the live-capture content to a file. Table 3-6 lists the settings chosen by the IP/TV Administrator when setting up a program that instructs IP/TV Server B in the main Zycorp network to record the live-capture program from the example shown in Table 3-4.

Step 2 Transfer the file to the IP/TV Server in Singapore using FTP. Refer to the "File Transfers" chapter in the IP/TV Administration and Configuration Guide for information on transferring files using FTP.

Step 3 Set up a scheduled program on the IP/TV Server in Singapore to play the file. This procedure would be very similar to the example provided in Table 3-3.
