AI Technical Summary
Existing video codec standards still have room for improvement in terms of encoding and decoding efficiency and bandwidth requirements when processing high-resolution video. In particular, the High Efficiency Video Coding (HEVC) standard suffers from inefficiencies in motion vector prediction and signaling methods.
Adaptive Motion Vector Resolution (AMVR) technology is employed to dynamically adjust the accuracy of Motion Vector Difference (MVD) through affine mode motion vector prediction (MVP) derivation and signaling, thereby improving encoding and decoding efficiency.
It improves the compression performance of video encoding and decoding, reduces bandwidth requirements, enhances encoding and decoding efficiency and video quality, and adapts to the encoding and decoding needs of different video content.
