Graphics Blending for High Dynamic Range Video
摘要:
A method for merging graphics and high dynamic range video data is disclosed. In a video receiver, a display management process uses metadata to map input video data from a first dynamic range into the dynamic range of available graphics data. The remapped video signal is blended with the graphics data to generate a video composite signal. An inverse display management process uses the metadata to map the video composite signal to an output video signal with the first dynamic range. To alleviate perceptual tone-mapping jumps during video scene changes, a metadata transformer transforms the metadata to transformed so that on a television (TV) receiver metadata values transition smoothly between consecutive scenes. The TV receiver receives the output video signal and the transformed metadata to generate video data mapped to the dynamic range of the TV's display.
