VIDEO DECODER CONFORMANCE FOR HIGH DYNAMIC RANGE (HDR) VIDEO CODING USING A CORE VIDEO STANDARD

摘要

In one example, a device for processing decoded video data a video decoder implemented by one or more hardware-based processing units comprising digital logic circuitry, and a postprocessing unit implemented by one or more hardware-based processing units comprising digital logic circuitry. The video decoder is configured to decode video data of a video bitsream according to a video coding standard, extract HDR postprocessing data from an SEI message of the video bitstream, and provide the decoded video data and the HDR postprocessing data to the postprocessing unit. The postprocessing unit is configured to process the decoded video data using the HDR postprocessing data according to the video coding standard. The device may additionally determine whether the video decoder is compliant with the video coding standard by comparing the processed video data with reference processed video data.

1. A method of processing decoded video data, the method comprising:
decoding, by a video decoder, video data of a video bitstream according to a video coding standard, the video bitstream including a supplemental enhancement information (SEI) message including high dynamic range (HDR) postprocessing data for the decoded video data; extracting, by the video decoder, the HDR postprocessing data from the SEI message; providing, by the video decoder, the decoded video data and the HDR postprocessing data to a postprocessing unit; and processing, by the postprocessing unit, the decoded video data using the HDR postprocessing data according to the video coding standard.
