  • Feature based bitrate allocation in non-backward compatible multi-layer codec via machine learning
    Patent number: 10123018
    Abstract: Novel methods and systems for non-backward compatible video encoding are disclosed. The bitrates of the base layer and enhancement layer are dynamically assigned based on features found in scenes in the video compared to a machine learned quality classifier.
    Type: Grant

  • Signal reshaping approximation
    Patent number: 10080026
    Abstract: Statistical values are computed based on received source images. An adaptive reshaping function is selected for one or more source images based on the one or more statistical values. A portion of source video content is adaptively reshaped, based on the selected adaptive reshaping function to generate a portion of reshaped video content. The portion of source video content is represented by the one or more source images. An approximation of an inverse of the selected adaptive reshaping function is generated. The reshaped video content and a set of adaptive reshaping parameters defining the approximation of the inverse of the selected adaptive reshaping function are encoded into a reshaped video signal. The reshaped video signal may be processed by a downstream recipient device to generate a version of reconstructed source images, for example, for rendering with a display device.
