  • Color metadata for a downlink data channel
    Patent number: 10129513
    Abstract: The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

  • Method and apparatus for color decision metadata generation
    Patent number: 8149338
    Abstract: A method presents metadata that is used for determining the color correction processes to be performed on image data representing a sequence of moving images. Instructions in the metadata controls how many color corrections are to be performed and when such operations occur. The image data is then subjected to the specified color correction operations that are performed at specified times and in a determined order. The image data is then rendered as a series of images by a rendering device. Optionally, different regions of the image data may be subjected to different color correction operations.
