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

A reception device, comprising:

• circuitry configured to
• receive a container of a predetermined format including a video stream obtained by encoding transmission video data,
• the transmission video data being obtained by performing photoelectric conversion on input data of a high dynamic range image,
• characteristic information for an electro-optical conversion of each predetermined unit of the transmission video data being inserted into a layer of the video stream and/or a layer of the container, the electro-optical conversion being an inverse of the photoelectric conversion, and
• process the video stream included in the container.

A transmission device, comprising:

• circuitry configured to
• transmit a container including a video stream including encoded data of transmission video data obtained by performing photoelectric conversion on input data of a high dynamic range image, and
• transmit a metafile including information for enabling a reception side to acquire the video stream,
• wherein characteristic information for an electro-optical conversion of each predetermined unit of the transmission video data is inserted into the video stream and/or the metafile and the electro-optical conversion is an inverse of the photoelectric conversion.
