Abstract
In the case where image data of a super-high definition service is transmitted without scalable coding, image data suitable to own display capability in a receiver not supporting the super-high definition service can be easily obtained. A container in a predetermined format having a video stream including encoded image data is transmitted. Auxiliary information for downscaling a spatial and/or temporal resolution of the image data is inserted into the video stream. For example, the auxiliary information indicates a limit of accuracy for a motion vector included in the encoded image data. Further, for example, the auxiliary information identifies a picture to be selected at the time of downscaling the temporal resolution at a predetermined ratio.
Claims11
A reception device, comprising:
- receiving circuitry configured to receive a broadcast signal having a video stream, the video stream including encoded image data and auxiliary information for a super-high resolution of the encoded image data;
- and
- processing circuitry configured to
- process identifying information for a super-high definition service of the video stream,
- apply processing for the super-high resolution to the encoded image data based on the auxiliary information, and
- obtain display image data for display,
- wherein the identifying information is included in a layer of the broadcast signal, such that the super-high definition service of the video stream can be identified at least on a per program basis.
A receiving method, comprising:
- receiving a broadcast signal having a video stream, the video stream including encoded image data and auxiliary information for a super-high resolution of the encoded image data;
- and
- in a case that identifying information indicates a super-high definition service,
- applying processing for the super-high resolution to the encoded image data based on the auxiliary information, and
- obtaining display image data for display,
- wherein the identifying information is included in a layer of the broadcast signal, such that the super-high definition service of the video stream can be identified at least on a per program basis.
A transmission device including:
- transmission circuitry configured to transmit a broadcast signal in a predetermined format having a video stream including encoded image data;
- and
- processing circuitry configured to insert, into a layer of the broadcast signal, identifying information such that a super-high definition service of the video stream can be identified at least on a per program basis.
A transmitting method including steps of:
- transmitting a broadcast signal in a predetermined format having a video stream including image data;
- and
- inserting, into a layer of the broadcast signal, identifying information such that a super-high definition service by the video stream can be identified at least on a per program basis.
