Title: COLOR GAMUT ADAPTATION WITH FEEDBACK CHANNEL
Abstract:
In general, this disclosure describes techniques for communicating preferred color gamut settings from a sink device to a source device. The source device may send, through a video interface, first video data to the sink device, which receives the first video data through the video interface. The sink device may then send, through a feedback channel of the video interface, preferred color gamut settings of the sink device to the source device. The preferred color gamut settings may be for content received from the source device. The source device may adapt second video data using the preferred color gamut settings. The source device may then send, through the video interface, the second video data adapted to the preferred color gamut settings to the sink device.
