Video Display Control Using Embedded Metadata

摘要

Systems, apparatus and methods are provided for generating, delivering, processing and displaying video data to preserve the video creator=s creative intent. Metadata which may be used to guide the processing and display of the video data is dynamically generated and embedded in the video data throughout a video delivery pipeline. The metadata may be embedded in the guard bits or least significant bits of chrominance channels of video data. Methods are provided for managing the encoding, delivery and decoding of the metadata to avoid unintentional communication of reserved words, minimize image artifacts which may result from overwriting least significant bits with metadata, prioritize delivery of metadata in the event of limited metadata bandwidth, and facilitate timely delivery of metadata to a downstream device.

1. A display, comprising:
a processor configured to receive image data comprising metadata and post-production adjusted image data, said meta-data comprising an identification of parameters of a post-production editing reference display used to produce the post-production adjusted image data; the processor further configured to extract the metadata and at least one of configure the display subsystem and processing the video data based at least in part on the metadata.
