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

Claim 6:
7. An information processing apparatus, comprising:
first circuitry configured to acquire 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
second circuitry configured to
perform decoding processing on the video stream to obtain the video data, and
perform an 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.
