  • Modulo embedding of video parameters
    Patent number: 9749626
    Abstract: A decoding method of selecting a value for a video parameter based on a portion of video data encoded in a video bitstream. The method receives the portion of encoded video data from the video bitstream and determines an aggregate value based on the received portion of the video data. The method determines a remainder by dividing the aggregate value with a predetermined value and then selects a value for the video parameter from a set of predefined values according to a mapping from the determined remainder, wherein the mapping has at least a plurality of values for a remainder corresponding to a single value for the video parameter. Associated methods for encoding are also disclosed.
