Classification: CPC H | IPC H

Claim 0:
1. A transmission device, comprising:
circuitry configured to
apply photoelectric conversion characteristics to high dynamic range video data to obtain transmission video data;
transmit a container including a video stream obtained by encoding the transmission video data; and
insert 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 into both a layer of the video stream and a layer of the container with different encoders 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, wherein

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.
