发明名称 Visual dynamic range timestamp to enhance data coherency and potential of metadata using delay information
摘要 A system and method for enhancing data coherency and potential of at least one metadata associated with a video data configured to operate in a visual dynamic range (VDR) format are detailed. One system embodiment employs a metadata framing structure which includes a header start of frame bit set, a packet type bit set, a configuration bit set, a variable depth configuration/metadata bit set, a header end of frame bit set, a timestamp bit set for specifying a frame delay count to apply the at least one metadata to the video data and a checksum check bit set. The at least one metadata is designed to embed within a code word guard bit position of at least one color channel of the video data and adaptable to embed within the VDR pipeline to enhance the quality of the video data.

主权项 1. A system for enhancing data coherency and potential of at least one metadata associated with a video data configured to operate in a visual dynamic range (VDR) format, the system comprising: a video encoder configured to associate video data with at least one metadata, the metadata further comprising: a metadata framing structure defined to include: a header start of frame bit set for identifying a start of the metadata framing structure;a packet type bit set for defining a payload and format of a subsequent metadata;a configuration bit set for defining a configurable portion of the metadata framing structure;a variable length configuration/metadata payload associated with the video data and at least one metadata associated with the video data;a header end of frame bit set for identifying an end of the header;a timestamp bit set for specifying a frame delay count to apply the at least one metadata to the video data; anda checksum check bit set for verifying data contained in the metadata framing structure; whereby metadata is embedded within a code word guard bit of at least one color channel of the video data.
