Abstract

A video encoder includes a motion search module that determines a motion search motion vector for a region of a selected picture of the plurality of pictures. The motion search module determines the region by merging selected ones of a plurality of blocks of the selected picture based on an evaluation of a cost matrix associated with the plurality of blocks of the selected picture.

Description

technical field [0001] This disclosure relates to encodings used in devices such as video encoders / decoders. Background technique [0002] Video coding has become an important problem for modern video processing devices. Robust encoding algorithms enable video signals to be transmitted with reduced bandwidth and stored in smaller memories. However, the accuracy of these encoding methods faces scrutiny from users accustomed to larger resolutions and higher image quality. Standards have been published for many coding methods, including the H.264 standard, also known as MPEG-4 Part 10 or Advanced Video Coding (AVC). Although this standard describes many powerful techniques, further refinements are possible to improve the performance and speed of implementations of such methods. Video signals encoded by these encoding methods must be similarly decoded for playback on most video display devices. [0003] Efficient and fast encoding and decoding of video signals is important t...
