Abstract

Method and system of supporting enhanced television (ETV) signaling. The method and system including combining multiple data types associated with ETV signaling in a common signal stream.

Claims

1. A transport stream for transporting signals associated with enhanced television (ETV), wherein the ETV requires the transport stream to include multiple data types, wherein at least a portion of the data types must relate to program association tables (PATs), program mapping tables (PMTs), video, audio, application information tables (AITs), application resources, media timelines, and stream events, the transport stream comprising:

a number of signaling streams for transporting signals associated with the data types; and

wherein at least one of the signaling streams is an integrated signaling stream (ISS) having signals associated with a plurality of the data types.

2. The transport stream of claim 1 wherein the ISS includes at least one of the data types related to the AIT, media timeline, or stream events.

3. The transport stream of claim 2 wherein the ISS includes data types related to each of the AIT, media timeline, and stream events.

4. The transport stream of claim 1 wherein the signaling streams are defined according to moving pictures expert group (MPEG) standards.

5. A system for supporting enhance television (ETV), the system comprising:

a number of ETV devices associated with supporting ETV, wherein at least a portion of the user devices are limited ETV devices having only 6 signaling streams filters;

a source configured generate a transport stream for transporting signals associated with the ETV to the user devices, wherein the transport stream includes a number of signaling streams having data types associated with program association tables (PATs), program mapping tables (PMTs), video, audio, application information tables (AITs), application resources, media timelines, and stream events;

wherein the source is configured to transport at least one of the signaling streams as an integrated signaling stream (ISS) having signals associated with a plurality of the data types so as to facilitate ETV with the user devices having only 6 signaling stream filters.

6. The system of claim 5 wherein the ISS includes at least one of the data types related to the AIT, media timeline, or stream events.

7. The transport stream of claim 5 wherein the ISS includes data types related to each of the AID, media timeline, and stream events.

9. The system of claim 5 wherein the signaling streams are defined according to moving pictures expert group (MPEG) standards.

10. The system of claim 5 wherein the source is configured to receive 8 separate signaling streams and wherein each one of the signaling streams is associated with one of the PATs, PMTs, video, audio, AITs, application resources, media timelines, and stream events, and wherein the source is configured to convert the 8 signaling streams to the transport having the 6 signaling streams.

8. The system of 7 wherein at least a portion of the user devices are non-limited ETV devices having at least 8 signaling stream filters, and wherein the source is configured to include at least 9 signaling streams within the transport, wherein at least one of the 9 signaling streams is associated with each of the PATs, PMTs, video, audio, AITs, application resources, media timelines, and stream events, and at least one of the 9 signaling streams is associated with the ISS such that non-limited devices filter the 8 signaling streams associated with the PATs, PMTs, video, audio, AITs, application resources, media timelines, and stream events, and the limited devices filter the 5 of the signaling streams associated with the PATs, PMTs, video, audio, application resources, and the ISS.

11. A method of supporting enhance television (ETV) of the type wherein an ETV transport stream requires multiple signal streams for transporting signals associated with a number of data types used to support the ETV, the method comprising:

combining multiple data types into one stream to provide an integrated signaling stream (ISS) having signals associated with the multiple data types such that the ETV is supported with a transport stream having the ISS as at least one of the signal streams.

12. The method of claim 11 further comprising determining the multiple data types combined into the ISS from the group comprising program association tables (PATs), program mapping tables (PMTs), video, audio, application information tables (AITs), application resources, media timelines, and stream events.

13. The method of claim 12 further comprising including only three of the data types from the group in the ISS such that at least six signal streams are included within the transport stream, one for the ISS and one for each of the data types not included within the ISS.

15. The method of claim 11 further comprising defining the transport stream according to moving pictures expert groups (MPEG) standards.

16. The method of claim 11 further comprising wirelessly transmitting the transport stream.

17. The method of claim 11 further comprising transmitting the ETV signaling stream over a cable television network.

18. The method of claim 11 further comprising packetizing the ETV signaling stream for transportation over a packet-switching network.

19. The method of claim 18 further comprising packetizing the ETV signaling stream according to Internet Protocol (IP).

20. The method of claim 11 further comprising combining only three data types into the ISS.

14. The method of 13 further comprising including three additional signal streams within the transport stream, one additional for each of the three data types included within the ISS, such that the transport stream includes nine signaling streams.
