Abstract

A method of swapping channels in a broadcast system includes a broadcast operation channel management system receiving broadcast operation channel swap data for a first station and a second station. The channel swap data comprises an effective date, a first station identifier and a first position and a second station identifier and a second position. A traffic scheduling system database communicates a first channel mapping data for a first channel to the broadcast operation channel management system. The traffic scheduling system database communicates a second channel mapping for a second channel to the broadcast operation channel management system. The broadcast operation channel updates the first channel mapping to form a first updated first channel mapping by setting a first end date of the first channel mapping to the effective date for the first station and communicating the first updated first channel mapping to the traffic scheduling database. The broadcast operation channel updating the second channel mapping to form a first updated second channel mapping by setting a second end date of the second channel mapping to the effective date for the first station and communicating the first updated second channel mapping to the traffic scheduling database. The broadcast operation channel forms a first new channel mapping for the first station with the effective date as the first start date and forms a second new channel mapping for the second station with the effective date as the second start date.

Claims

1. A method comprising:

communicating broadcast operation channel swap data for a first station and a second station to a broadcast operation channel management system, said channel swap data comprising an effective date, a first station identifier and a first position and a second station identifier and a second position;

communicating a first channel mapping data for a first channel from a traffic scheduling system database to the broadcast operation channel management system;

communicating a second channel mapping for a second channel from a traffic scheduling system database to the broadcast operation channel management system;

updating the first channel mapping to form a first updated first channel mapping by setting a first end date of the first channel mapping to the effective date for the first station;

communicating the first updated first channel mapping to the traffic scheduling database;

updating the second channel mapping to form a first updated second channel mapping by setting a second end date of the second channel mapping to the effective date for the first station;

communicating the first updated second channel mapping to the traffic scheduling database;

forming a first new channel mapping for the first station with the effective date as the first start date at the broadcast operation channel management system; and

forming a second new channel mapping for the second station with the effective date as the second start date at the broadcast operation channel management system.

2. A method as recited in claim 1 further comprising communicating a broadcast operation channel swap command to a broadcast operation channel from an engineering module.

3. A method as recited in claim 1 further comprising generating a first channel mapping data request from the broadcast operation channel management system to a traffic and scheduling database.

4. A method as recited in claim 1 further comprising generating a second channel mapping data request from the broadcast operation channel management system to the traffic and scheduling database.

5. A method as recited in claim 1 wherein the first channel mapping comprises a first mapping for a first schedule channel.

6. A method as recited in claim 1 wherein the first channel mapping comprises a first mapping for a first guide channel.

7. A method as recited in claim 1 wherein the first channel mapping comprises a first schedule channel and a first guide channel.

8. A method as recited in claim 1 wherein the second channel mapping comprises a second mapping for the second schedule channel.

9. A method as recited in claim 1 wherein the second channel mapping comprises a second mapping for a second guide channel.

10. A method as recited in claim 1 wherein the second channel mapping comprises a second schedule channel and a second guide channel.

11. A method as recited in claim 1 wherein the first channel mapping data comprises transponder data.

12. A method as recited in claim 1 wherein the second channel mapping data comprises transponder data.

13. A method as recited in claim 1 wherein the first channel mapping data comprises bit rate allocation for a satellite transponder.

14. A method as recited in claim 1 wherein the second channel mapping data comprises bit rate allocation for a satellite transponder.

15. A method as recited in claim 1 wherein communicating broadcast operation swap data comprises communicating broadcast operation swap data from an engineering module.

16. A system comprising:

a broadcast operation channel management system receiving broadcast operation channel swap data for a first station and a second station, said channel swap data comprising an effective date, a first station identifier and a first position and a second station identifier and a second position;

a traffic scheduling system database communicating a first channel mapping data for a first channel to the broadcast operation channel management system, said traffic scheduling system database communicating a second channel mapping for a second channel to the broadcast operation channel management system;

said broadcast operation channel updating the first channel mapping to form a first updated first channel mapping by setting a first end date of the first channel mapping to the effective date for the first station and communicating the first updated first channel mapping to the traffic scheduling database;

said broadcast operation channel updating the second channel mapping to form a first updated second channel mapping by setting a second end date of the second channel mapping to the effective date for the first station and communicating the first updated second channel mapping to the traffic scheduling database;

said broadcast operation channel forming a first new channel mapping for the first station with the effective date as the first start date and forming a second new channel mapping for the second station with the effective date as the second start date.

17. A system as recited in claim 16 wherein the first channel mapping comprises a first mapping for a first schedule channel.

18. A system as recited in claim 16 wherein the first channel mapping comprises a first mapping for a first guide channel.

19. A system as recited in claim 16 wherein the first channel mapping comprises a first mapping first schedule channel and a first guide channel.

20. A system as recited in claim 16 wherein the second channel mapping comprises a second mapping for first schedule channel.

21. A system as recited in claim 16 wherein the second channel mapping comprises a second mapping for a second guide channel.

22. A system as recited in claim 16 wherein the second channel mapping comprises a second mapping second schedule channel and a second guide channel.
