Abstract
To enable a receiving side to appropriately perform processing of obtaining display image data from transmission video data having a predetermined photoelectric conversion characteristic. Input video data is processing and transmission video data having a predetermined photoelectric conversion characteristic is obtained. Encoding processing is applied to the transmission video data and a video stream is obtained. A container of a predetermined format, including the video stream, is transmitted. Information indicating a photoelectric conversion of the input video data is inserted into the video stream and/or the container.
Claims14
A transmitting device comprising:
- a photoelectric conversion processing unit configured to process input video data to obtain transmission video data having a predetermined photoelectric conversion characteristic;
- an encoding unit configured to apply encoding processing to the transmission video data to obtain a video stream;
- a transmitting unit configured to transmit a container of a predetermined format, including the video stream;
- and
- an information insertion unit configured to insert information indicating a state of photoelectric conversion of the input video data into the video stream and/or the container.
