  • H.264 Data processing
    Publication number: 20080165860
    Abstract: Picture order count values are used to calculate a distance scale factor in the H.264 scheme. The distance scale factor can be used as a parameter in temporal direct prediction and weighted prediction. A decoder can operate on video slices containing picture data. Each video slice can contain references to previous and subsequent pictures using POC values. The POC values are stored as a 16-bit difference from an offset. An algorithm utilizes the POC values to output the distance scale factor. Embodiments of the invention can improve the efficiency of a decoder and can reduce storage requirements for POC values associated with H.264 video slices.
