SIGNALING TARGET DISPLAY PARAMETERS OF COLOR REMAPPING INFORMATION IN SUPPLEMENTAL ENHANCEMENT INFORMATION MESSAGES

摘要

This disclosure describes techniques for communicating optimal coding parameters between a source device and a sink device. The sink device may receive, in a bitstream, video data and a group of one or more supplemental enhancement information (SEI) messages, wherein each SEI message comprises indications of a set of display capabilities and a set of remapping parameters. The sink device may then, for each SEI message of the group of one or more SEI messages, compare the respective set of display capabilities indicated in the respective SEI message with a target set of display capabilities for the sink device. Responsive to determining that a first set of display capabilities indicated by a first SEI message is compatible with the target set of display capabilities, the sink device may adapt the video data using a respective set of remapping parameters indicated by the first SEI message.
