Abstract

Official abstract text for this publication.

Embodiments of a method and system for inter-prediction 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 units of video data in a frame are to be processed using an inter-prediction operation. In an embodiment, inter-prediction is performed on a frame basis such that inter-prediction is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the inter-prediction such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.

First claim

Opening claim text (preview).

What is claimed is: 1. A video data decoding method comprising: pre-processing control maps generated from encoded video data that was encoded according to a pre-defined format, wherein pre-processing comprises generating a plurality of intermediate control maps for a respective plurality of frame processing operations containing control information, the control information including an indication of which macro blocks or portions of macro blocks of a frame may be processed in par…
