High Efficiency Video CodingHigh Efficiency Video Coding, HEVC, H265 and MPEG-H Part 2, is a video compression standard designed as a successor to the widely used Advanced Video Coding (AVC, H264, or MPEG-4 Part 10).Video CompressionAVC, H264 bitstream is a block-oriented standard with motion competition by breaking an image down into macroblocks of pixel squares. AVC uses the integer discrete cosine transform (DCT) with macroblocks of 4×4 and 8×8 block sizes or as large as 16×16 pixels. These can be further divided into transform and prediction blocks.HEVC, h265 bitstream is also a block-oriented standard by breaking an image down into coding tree units (CTUs) of pixel squares. HEVC uses integer DCT and DST transforms with varied block sizes between 4×4 and 32×32 and is up to 64×64 pixels.
