An extension of direct macroblock coding in Predictive (P) slices of the H.264 standard
The consideration of better motion compensation techniques for inter-frame prediction is one of the key reasons why the new H.264 (MPEG-4 AVC) video coding standard can achieve considerably better coding efficiency compared to older standards such as MPEG2/4 and H.263. These include the use of multiple references and block sizes, a better interpolation filter for subpixel motion compensation, and more efficient exploitation of the spatio-temporal correlation between motion vectors of adjacent blocks through the consideration of SKIP and DIRECT modes. In this paper we introduce additional methods into H.264 that further enhance motion compensation and can lead to additional improvements in coding efficiency. This is achieved by further exploiting motion vector temporal
