Abstract

A method and system for configuring broadcast components includes a broadcast operation channel management system (BMS) forming a bit rate allocation chart and a compression control system storing a stream map having a channel lineup. The BMS retrieves the channel line up from the compression control system and modifying the channel lineup to form a modified channel line up. The BMS communicates the modified channel lineup to the compression control system.

Claims

1. A method comprising:

forming a bit rate allocation chart at a broadcast operation channel management system (BMS);

storing a stream map having a channel line-up in a compression control system, said channel line-up comprising input channel data, output transport data and a bit rate group identifier;

retrieving the channel line-up from the compression control system at the broadcast operation channel management system;

modifying the channel line-up at BMS to form a modified channel line-up based on the bit rate allocation chart; and

communicating the modified channel line-up from the BMS to the compression control system.

2. A method as recited in claim 1 wherein the input channel data comprises a service identifier, a video standard value, and an audio bit rate.

3. A method as recited in claim 1 wherein the output transport data comprises an orbital slot identifier, a transponder number and a service identifier.

4. A method as recited in claim 1 wherein the output transport data comprises a group bit rate.

5. A method as recited in claim 1 further comprising configuring a multiplexer in response to the modified channel line-up.

6. A method as recited in claim 1 further comprising configuring an encoder in response to the modified channel line-up.

7. A method as recited in claim 1 further comprising uplinking a transport stream signal to the satellite using the encoder and multiplexer.

8. A method as recited in claim 1 wherein communicating the modified channel line-up from the BMS to the compression control system comprises communication using XML.

9. A system comprising:

a broadcast operation channel management system (BMS) forming a bit rate allocation chart;

a compression control system storing a stream map having a channel line-up, said channel line-up comprising input channel data, output transport data and a bit rate group identifier;

said BMS retrieving the channel line-up from the compression control system and modifying the channel line-up to form a modified channel line-up based on the bit rate allocation chart; and

said BMS communicating the modified channel line-up to the compression control system.

10. A system as recited in claim 9 wherein the input channel data comprises a service identifier, a video standard value, and an audio bit rate.

11. A system as recited in claim 9 wherein the output transport data comprises an orbital slot identifier, a transponder number and a service identifier.

12. A system as recited in claim 9 wherein the output transport data comprises a variable bit rate pool identifier and a pool bit rate.

13. A system as recited in claim 9 wherein said compression control system configures a multiplexer in response to the modified channel line-up.

14. A system as recited in claim 9 wherein said compression control system configures an encoder in response to the modified channel line-up.

15. A system as recited in claim 9 further a satellite comprising uplinking a transport stream signal to the satellite through an encoder and a multiplexer configured according to the modified channel line-up.
