  • Video encoding
    Patent number: 10542277
    Abstract: A method of video encoding is provided. The method includes downscaling a block of a frame of a video to generate a downscaled block. The method includes downscaling a reference block of a reference frame of the video to generate a downscaled reference block. The method includes processing the downscaled block to calculate first compression efficacy data indicative of a first efficacy of encoding the block using intra-frame prediction. The method includes processing the downscaled block and the downscaled reference block to calculate second compression efficacy data indicative of a second efficacy of encoding the block using inter-frame prediction. The method includes based on at least one of the first compression efficacy data or the second compression efficacy data, determining that the block is to be encoded using inter-frame prediction. Other methods of video encoding and a video encoder system are also provided.
