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 Program Manager. The two IP/TV Servers on the network serve media files, whether scheduled, live or on-demand.
•A second network is located in the Zycorp 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 Program Manager and one IP/TV Server. The IP/TV Server serves both scheduled and on-demand programs.
•A third network is located in the Zycorp sales office in Mexico City. This network can be reached from the main network through the Internet. About five IP/TV Viewer users are on this network, and one IP/TV Server. There is no IP/TV Program Manager; the IP/TV Server and all IP/TV Viewers are configured to get their program information from the IP/TV Program Manager in San Jose.
•A fourth network is located in the Zycorp manufacturing plant in Singapore. This network can be reached from the main network through the Internet. About 50 IP/TV Viewer users are on this network, along with one IP/TV Program Manager and one IP/TV Server.
Note Programs defined on the San Jose network that use administratively scoped addresses are not visible to IP/TV Viewer users on the Mexico City or Singapore networks, or to IP/TV Program Managers or IP/TV Servers on those networks. See the "Multicast Addresses" section for information about using scoped addresses to limit the range of IP/TV programs.
Figure 11-1 shows all of the IP/TV Servers and IP/TV Program Managers on each network, but only one sample PC running IP/TV Viewer on each network.

Sample On-Demand Category
Table 11-1 lists the settings chosen by the IP/TV administrator to set up an on-demand category on the IP/TV Program Manager on the Zycorp headquarters network. These settings are shown in Figure 5-7.

Sample On-Demand Program
Table 11-2 lists the settings chosen by the IP/TV administrator to set up an on-demand program on IP/TV Program Manager on the Zycorp headquarters network and autodistribute the program to a second server. Figure 5-10, Figure 5-11, and Figure 5-15 show these settings.
Note When a value is listed as Default, the IP/TV administrator accepted the value assigned by IP/TV Program Manager.
This program is defined within the on-demand category Instructional Videos (see Table 11-1).
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, is automatically distributed to Server A. Autodistributing the media file allows IP/TV Program Manager to balance the load of requests for the program.

Sample Scheduled Program to Play a Media File
Table 11-3 lists the settings chosen by the IP/TV administrator to set 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.
The film was provided by Mega Insurance Company, the company that offers the 401(k) plan, and the Zycorp coverage contract requires that the Mega Insurance copyright be included in the program listing information.
The Human Resources director wants the program to be played every Monday at 1100 Pacific time, which is 1400 Eastern time, through the end of the year.
Table 11-3 lists all the parameters on the New Program page and gives a recommended setting for each parameter. Figure 6-4, Figure 6-5, and Figure 6-7 show these settings.
Note When a value is listed as Default, the IP/TV administrator accepted the value assigned by IP/TV Program Manager.

Sample Scheduled Live-Capture Program
Table 11-4 lists the settings chosen by the IP/TV administrator to set up a schedule for a live-capture program.
The program is a 15-minute invitation to the annual company picnic. The invitation will be filmed on the Monday before the picnic, and multicast simultaneously. The program applies to employees in San Jose only.
Note When a value is listed as Default, the IP/TV Administrator accepted the value assigned by IP/TV Program Manager.
Figure 6-4, Figure 6-5, Figure 6-6, and Figure 6-7 show these settings.

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 11-5 lists the settings chosen by the IP/TV Administrator to set up a program to accomplish this using SmallCast. Figure 6-4, Figure 6-5, Figure 6-6, and Figure 6-7 show these settings.
The capture server in San Jose must be configured to be able to use SmallCast to send the program to the IP/TV Server in Mexico City. See the "Defining Servers and Server Clusters" section for information on defining servers.
Note Where a value is listed as Default, the IP/TV administrator has accepted the value assigned by IP/TV Program Manager.

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 program to a file.
Table 11-6 lists the settings chosen by the IP/TV administrator to set up a program that instructs IP/TV Server B in the main Zycorp network to record the live-capture program using the settings from Table 11-4.
Note When a value is listed as Default, the IP/TV administrator has accepted the value assigned by IP/TV Program Manager.

Step 2 Transfer the file to the IP/TV Server in Singapore using FTP.
Refer to the Cisco IP/TV Broadcast Server User 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 similar to the example provided in Table 11-3.
Figure 6-15, Figure 6-15, Figure 6-17, and Figure 6-18 show these settings.
