Abstract
A method of creating an audio-video stream comprises multiplexing a video component, an audio component, a content reference identifier, and a semantic data packet containing information on the relationship between the video component and the content reference identifier. Apparatus for receiving the audio-video stream, and apparatus for transmitting the audio/video stream are disclosed.
Claims23
A method of creating an audio/video stream comprising combining a video component, an audio component, a content reference identifier (CRID), and a semantic data packet containing information on a relationship between the video component and the CRID, wherein the CRID uniquely identifies content for requesting the content using the CRID,
- wherein, when the relationship includes a label of a current content including the video component, then the CRID embedded in the audio/video stream is for the video component and is used to obtain enhanced information about the video component, and
- wherein, when the relationship includes a further label comprising a recommendation for a further content related to the current content including programs recommended by a broadcaster, then the CRID refers to the further content and is used for obtaining information about the further content, and
- selection of the current content records the programs recommended by the broadcaster without recording the current content.
An apparatus for transmitting an audio/video stream comprising:
- a content stream input for receiving at least one of a video component and an audio component,
- a data stream input for receiving a content reference identifier (CRID) and a semantic data packet containing information on a relationship between the video component and the CRID,
- an audio/video stream generator for generating an audio/video stream from the content stream and the data stream, and
- a transmitter capable of transmitting the audio/video stream, wherein a current identifier of a current content related to a future program recommended by a broadcaster is related to the future program so that selecting recording of the current content will record the future program recommended by the broadcaster and will not record the current content when the relationship includes a further label for the future program related to the current content, so that the CRID refers to the future program and is used for obtaining information about the future program, wherein the CRID uniquely identifies content for requesting the content using the CRID,
- wherein, when the relationship includes a label of a current content including the video component, then the CRID embedded in the audio/video stream is for the video component and is used to obtain enhanced information about the video component.
An apparatus for receiving an audio/video stream comprising an audio/video stream receiver, said audio/video stream comprising a video component, an audio component, a content reference identifier (CRID), and a semantic data packet containing information on a relationship between the video component and the CRID, and a stream splitter for splitting said audio/video stream into at least two of its constituent parts, wherein the CRID uniquely identifies content for requesting the content using the CRID,
- wherein, when the relationship includes a label of a current content including the video component, then the CRID embedded in the audio/video stream is for the video component and is used to obtain enhanced information about the video component, and
- wherein, when the relationship includes a further label comprising a recommendation for a further content related to the current content including programs recommended by a broadcaster, then the CRID refers to the further content and is used for obtaining information about the further content, and
- selection of the current content records the programs recommended by the broadcaster without recording the current content.
