Video decoding apparatus with adaptive motion vector difference resolution
A recently granted patent (Publication Number: US11962798B2) discloses a video decoding apparatus designed to decode a sequence of pictures split into blocks. The apparatus includes a processor that extracts identification and size information from the sequence's header in the bitstream. This information is used to split coding tree blocks in a tree structure, determine current blocks to be decoded, and reconstruct motion vectors. The processor can also handle adaptive motion vector resolution and generate motion vectors based on neighboring blocks. The patent details the extraction of motion vector resolution information and the encoding of motion vector differences with various precision levels, including ¼ pixel precision.
Furthermore, the patent describes a video encoding apparatus that complements the decoding apparatus. This encoding apparatus encodes motion vector differences and resolution information into the bitstream, allowing for efficient video data transmission. The method involves encoding identification and size information, splitting coding tree blocks, determining motion vectors, and encoding motion vector differences with different precision levels. The encoding process includes the use of motion vector resolution flags and alternative resolution information, ensuring accurate representation of motion vectors. The patent also outlines a method for transmitting the encoded video data in a bitstream format, emphasizing the importance of adaptive motion vector resolution and precise encoding techniques for efficient video transmission.
