Abstract

A signaling method of video content and services broadcast by to a multitude of reception devices, the contents being encoded into data packets transmitted in a transport stream associated with a signaling stream is disclosed that comprises an insertion step of a unique identifier associated with each of the video contents or services in the signaling stream; an insertion step of the unique identifier into packets of the transport stream transmitting the video content or service corresponding to the unique identifier. Advantageously, the unique identifier is derived from a characteristic of the content among the title of the video content or service, the date and theoretical continuous broadcast time of the video content or service. A method for recording and a recording device using the signaling is further disclosed.

Claims

1-13. -13. (canceled)

14. A method for signaling video content and services broadcast to a plurality of reception devices, said contents being encoded into data packets transmitted in transport packets of a transport stream, said transport stream being associated with a signaling stream, said method comprising the steps for:

inserting a unique identifier associated with each of said video content or services into said signaling stream,

inserting said unique identifier into at least a transport packet of the transport stream, said transport packet comprising at least a data packet of the encoded video content or service corresponding to said unique identifier.

15. The method according to claim 14, wherein the unique identifier associated with each of said video contents of services is derived from a characteristic among the following characteristics:

the title of the video content or service,

the theoretical date and time of the continuous broadcast of the video content or service.

16. The method according to claim 14, wherein the unique identifier is inserted into at least an ES transport packet of the transport stream comprising at least a data packet, said ES transport packet called main ES transport packet being identified by a PID determined in a transport stream compliant with the MPEG standard.

17. The method according to claim 16, wherein a data packet from a main ES transport packet is systematically decoded.

18. The method according to claim 16, wherein the unique identifier associated with each of said video contents or services is inserted into the extension field of RTS packets of an IP transport stream.

19. The method according to claim 16, wherein the unique identifier associated with each of said video contents or services is inserted as private data into the adaptation field of transport packets of an MPEG2-TS transport stream.

20. A method for recording video contents and services broadcast to a plurality of reception devices, said contents being encoded into data packets transmitted in transport packets of a transport stream, said transport stream being associated with a signaling stream, said method comprising the steps for:

reception of said signaling stream;

detecting a unique identifier associated with each of said video contents or services into said signaling stream, said unique identifier corresponding to video content or service to record;

reception of data packets transmitted into transport packets of said transport stream;

detecting said unique identifier into at least a transport packet of the transport stream, said transport packet comprising at least a data packet of the encoded video content or service to record,

and when said unique identifier is detected in transport packets of the transport stream, recording of each data packet comprised in the transport packets of the transport stream comprising said unique identifier and associated with the video content or service to record.

21. The method according to claim 20 wherein the step for recording further comprises recording data packets comprised into second transport packets of the transport stream, said second transport packets being associated to transport packets comprising said unique identifier.

22. The method according to claim 20, said method further comprising a step for selecting a video content or service to record and for determining the unique identifier from data of the signaling stream corresponding to said video or service content to record.

23. The method according to claim 20, said method further comprising a step for activating data packet reception of the transport stream from data of the signaling stream.

24. The method according to claim 23, wherein the unique identifier is inserted into at least an ES transport packet comprising at least a data packets, said ES transport packet called main ES transport packets being identified by a PID determined in a stream compliant with the MPEG standard.

25. The method according to claim 24 wherein the step for recording further comprises recording data packets comprised into second transport packets of the transport stream, said second transport packets being associated to transport packets comprising said unique identifier from a PMT table comprised in a stream compliant with MPEG standard.

26. The method according to claim 24, wherein the unique identifier associated with each of said video contents or services is inserted into the extension field of RTS packets of an IP transport stream.

27. The method according to claim 24, wherein the unique identifier associated with each of said video contents or services is inserted as private data into the adaptation field of packets of an MPEG2-TS transport stream.

28. A recording device of video contents and services broadcast to a plurality of said reception devices, said contents being encoded into data packets transmitted in transport packets of a transport stream, said transport stream being associated with a signaling stream, comprising:

a receiver for said signaling stream,

means for detecting a unique identifier associated with each of said video contents or services into said signaling stream, said unique identifier corresponding to video content or service to record;

a receiver for data packets transmitted into transport packets of said transport stream,

means for detecting said unique identifier into at least a transport packet of the transport stream, said transport packet comprising at least a data packet of the video content or service to record,

means for recording each data packet comprised in the transport packets of the transport stream comprising said detected unique identifier and associated with the video content or service to record.
