Method for signaling broadcast video content, and recording method and device using the signaling
First Claim
1. A method for signaling audiovisual contents comprising:
- inserting an identifier associated with a first audiovisual content into a signaling stream, said signaling stream describing said first audiovisual content, said describing said first audiovisual content comprising including a name and a channel for said first audiovisual content, said first audiovisual content including a plurality of content streams, each content stream being one of audio and video and encoded into data packets, said data packets included in transport packets of a transport stream, said transport stream including a plurality of audiovisual contents and being adapted to be broadcast to a plurality of reception devices, wherein said identifier uniquely determines said first audiovisual content in said signaling stream and in said transport stream;
inserting said identifier into at least one first transport packet of said transport stream, said at least one first transport packet comprising at least one data packet of one of said plurality of content streams of said first audiovisual content,wherein said identifier is derived from at least one characteristic comprising a title of said first audiovisual content and said transport stream is one of an internet protocol (IP) transport stream and said identifier is inserted into an extension field of real-time transport protocol (RTP) packets of said IP transport stream and a moving picture expert group 2 transport stream (MPEG2-TS) and said identifier is inserted as private data into an adaptation field of transport packets of said MPEG2-TS transport stream.

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.
