Classification: CPC H | IPC H

Claim 10:
11. A reception method, comprising
receiving a container including a video stream obtained by encoding transmission video data and having a predetermined format by circuitry, wherein
the transmission video data is obtained by applying photoelectric conversion characteristics to high dynamic range video data,
type information to designate which of a plurality of types of conversion characteristics corresponds to the applied photoelectric conversion characteristics for photoelectric conversion of the transmission video data is inserted into both a layer of the video stream and a layer of the container with different encoders, a first encoder inserting the information into the layer of the video stream before a second encoder inserting the information into the layer of the container,
each of the plurality of types of conversion characteristics is mapped to a different value of the type information,
the applied photoelectric conversion characteristics are limited to one of a plurality of photoelectric conversions characteristics corresponding to the plurality of types of conversion characteristics with the mapped values, and
the reception method further comprises processing a video stream included in the received container,
circuitry configured to transmit a container including a video stream including encoded data of transmission video data obtained by applying photoelectric conversion characteristics to high dynamic range video data, wherein
type information to designate which of a plurality of types of conversion characteristics corresponds to the applied photoelectric conversion characteristics for photoelectric conversion of the transmission video data is inserted into a layer of the video stream and a layer of the container,
each of the plurality of types of conversion characteristics is mapped to a different value of the type information, and
the applied photoelectric conversion characteristics are limited to one of a plurality of photoelectric conversions characteristics corresponding to the plurality of types of conversion characteristics with the mapped values.
