Abstract

Television program transmitting methods and systems transmit multiple program channels when at least some of the multiple program channels have different content, and transmit a single program channel in place of the multiple program channels when the multiple program channels have common content. Additional content may be transmitted on at least one of the program channels that have freed up when the multiple program channels have common content.

Claims

1. A television program transmitting method comprising:

transmitting a plurality of program channels when at least some of the plurality of program channels have different content; and

transmitting a single program channel in place of the plurality of program channels when the plurality of program channels have common content.

2. A method according to claim 1 further comprising:

transmitting additional content on at least one of the plurality of program channels when the plurality of program channels have common content.

3. A method according to claim 1:

wherein transmitting a plurality of program channels is preceded by decombining the single program channel into the plurality of program channels when at least some of the plurality of program channels have different content; and

wherein transmitting a single program channel is preceded by combining the plurality of program channels into the single program channel when the plurality of program channels have common content.

4. A method according to claim 1 wherein the common content comprises national content, regional content or local content and wherein the different content comprises regional content, local content or commercials, respectively.

5. A method according to claim 1 wherein the common content comprises a common television program and wherein the different content comprises different commercials.

6. A method according to claim 2 wherein the additional content comprises a high bit rate transmission of the common content, High Definition Television (HDTV) content and/or content to be stored in a set top box.

7. A method according to claim 1 wherein transmitting a plurality of program channels is preceded by time synchronizing the plurality of program channels.

8. A method according to claim 2 wherein transmitting additional content comprises transmitting High Definition Television (HDTV) content on the plurality of program channels when the plurality of program channels have common content.

9. A method according to claim 1 wherein transmitting a plurality of program channels and transmitting a single program channel are repeatedly performed sequentially.

10. A method according to claim 1 wherein transmitting a plurality of program channels and transmitting a single program channel are performed by a Direct Broadcast Satellite (DBS) broadcasting system.

11. A channel combining and decombining method for a Direct Broadcast Satellite (DBS) system comprising:

transmitting a single channel of a program in place of a group of identical channels, and reverting to transmission of the group of channels when the content being broadcast no longer is identical among the group of channels.

12. A method according to claim 11 further comprising transmitting additional information on at least one channel in the group of channels while the singular channel is transmitted.

13. A television program receiving method comprising:

receiving at least one of a plurality of program channels when at least some of the plurality of program channels have different content; and

receiving a single program channel in place of at least one of the plurality of program channels when the plurality of program channels have common content.

14. A method according to claim 13 further comprising:

receiving additional content on at least one of the plurality of program channels when the plurality of program channels have common content.

15. A method according to claim 13 wherein the common content comprises a common television program and wherein the different content comprises different commercials.

16. A method according to claim 13 wherein receiving additional content comprises receiving High Definition Television (HDTV) content on at least one of the plurality of program channels when the plurality of program channels have common content.

17. A method according to claim 13 wherein receiving at least one of a plurality of program channels and receiving a single program channel are repeatedly performed sequentially.

18. A method according to claim 13 wherein receiving at least one of a plurality of program channels and receiving a single program channel are performed at a Direct Broadcast Satellite (DBS) set top box.

19. A television program broadcasting system comprising:

a transmitter that is configured to transmit a plurality of program channels when at least some of the plurality of program channels have different content and to transmit a single program channel in place of the plurality of program channels when the plurality of program channels have common content.

20. A system according to claim 19 wherein the transmitter is further configured to transmit additional content on at least one of the plurality of program channels when the plurality of program channels have common content.

21. A system according to claim 19 wherein the transmitter is a first transmitter, the system further comprising:

a second transmitter that is configured to transmit additional content on at least one of the plurality of program channels when the plurality of program channels have common content.

22. A system according to claim 19 further comprising:

a switch that is configured to select a plurality of program channels in place of the single program channel when at least some of the plurality of program channels have different content and to select the single program channel in place of the plurality of program channels when the plurality of program channels have common content, wherein the transmitter is responsive to the switch.

23. A system according to claim 19 wherein the common content comprises national content, regional content or local content and wherein the different content comprises regional content, local content or commercials, respectively.

24. A system according to claim 19 wherein the common content comprises a common television program and wherein the different content comprises different commercials.

25. A system according to claim 20 wherein the additional content comprises a high bit rate transmission of the common content, High Definition Television (HDTV) content and/or content to be stored in a set top box.

26. A system according to claim 22 further comprising a synchronizer that is configured to synchronize the plurality of program channels, wherein the switch is responsive to the synchronizer.

27. A system according to claim 19 wherein the television broadcast system comprises a Direct Broadcast Satellite (DBS) broadcast system.

28. A set top box comprising:

a receiver that is configured to receive at least one of a plurality of program channels when at least some of the plurality of program channels have different content and to receive a single program channel in place of the plurality of program channels when the plurality of program channels have common content.

29. A set top box according to claim 28 wherein the receiver is further configured to receive additional content on at least one of the plurality of program channels when the plurality of program channels have common content.

30. A set top box according to claim 28 wherein the common content comprises a common television program and wherein the different content comprises different commercials.

31. A set top box according to claim 29 wherein the additional content comprises High Definition Television (HDTV) content.

32. A set top box according to claim 28 wherein the set top box is a Direct Broadcast Satellite (DBS) set top box.

33. A television program transmitting system comprising:

means for transmitting a plurality of program channels when at least some of the plurality of program channels have different content; and

means for transmitting a single program channel in place of the plurality of program channels when the plurality of program channels have common content.

34. A system according to claim 33 further comprising:

means for transmitting additional content on at least one of the plurality of program channels when the plurality of program channels have common content.
