Transmission device, transmission method, reception device, reception method, display device, and display method

Abstract

A transmission device including circuitry is provided. The circuitry is configured to apply photoelectric conversion characteristics to high dynamic range video data to obtain transmission video data. The circuitry is configured to transmit a container including a video stream obtained by encoding the transmission video data. The circuitry is configured to insert type information to designate the type of conversion characteristics corresponding to the applied photoelectric conversion characteristics for photoelectric conversion of the transmission video data into a layer of the video stream and/or a layer of the container. The type of the conversion characteristics designated by the type information is determined regardless of luminance of a display.

1 . A reception device, comprising:
 circuitry configured to
 receive video data of a high dynamic range video and characteristic information for an electro-optical conversion of the video data, the video data being obtained by applying a photoelectric conversion characteristic to high dynamic range video input data, the characteristic information indicating a type for the electro-optical conversion that corresponds to a high dynamic range curve, the high dynamic range curve having a compatibility with a non-high dynamic range gamma curve; and 
 process the received video data.
