TRANSMITTING DISPLAY MANAGEMENT METADATA OVER HDMI |
摘要 |
In an embodiment, a source video signal comprising reference code values and mapping function parameters for one or more mapping functions to map the reference code values to device-specific pixel values. The reference code values and the mapping function parameters are combined into first video frames in a first video signal format. The mapping function parameters represent DM metadata carried in the first video frames. Second video frames in a second video signal format are generated based on the first video frames in the first video signal format and a mapping between the first video signal format and the second video signal format. The second video frames are sent to a video sink device through the video link in an encoded video signal of the second video signal format. |
