First Claim
Patent Images
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.

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. - View Dependent Claims (6, 7, 9, 10)

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. - View Dependent Claims (12, 13, 15, 16, 17, 18, 19, 20)
