Abstract

Embodiments of a method and system for motion compensation in decoding video data are described herein. In various embodiments, a high-compression-ratio codec (such as H.264) is part of the encoding scheme for the video data. Embodiments pre-process control maps that were generated from encoded video data, and generating intermediate control maps comprising information regarding decoding the video data. The control maps indicate which one of multiple prediction operations is to be used in performing motion compensation on particular units of data in a frame. In an embodiment, motion compensation is performed on a frame basis such that each of the multiple prediction operations is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the motion compensation such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.
