Assignee: SONY GROUP CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 12:
13. An information processing system, comprising:
a receiver device; and
a display device,
wherein the receiver device includes
receiver circuitry configured to receive a container including a video stream, the video stream corresponding to encoded video data, wherein first metadata information indicating a standard dynamic range (SDR) opto-electronic transfer characteristic is inserted into the video stream, and second metadata information indicating a high dynamic range (HDR) opto-electronic transfer characteristic is inserted into the container or the video stream, the SDR opto-electronic transfer characteristic and the HDR opto-electronic transfer characteristic each relating a brightness level to a code value; and

first processing circuitry configured to
perform decoding processing on the video stream to obtain the video data, and
transmit the obtained video data and the second metadata information indicating the HDR opto-electronic transfer characteristic to the display device, and

the display device includes
second processing circuitry configured to perform a HDR electro-optical conversion, with a characteristic opposite to the HDR opto-electronic transfer characteristic, on the video data to obtain video data for display, based on the second metadata information indicating the HDR opto-electronic transfer characteristic.
