Method and system for motion compensated picture rate up-conversion using information extracted from a compressed video stream

摘要

Certain aspects of a method and system for motion-compensated picture rate up-conversion (PRUC) using information extracted from a compressed video stream may include extracting PRUC data from a compressed video data stream while the compressed video data stream is being decompressed by a video decompression engine. The PRUC data may comprise, for example, local block motion vectors, block coding modes, quantization levels, quantized residual data and decoded pictures. A plurality of interpolated pictures may be generated based on extracting the PRUC data.

1. A method, the method comprising:
in a video decoder comprising a video decompression engine and a picture rate up-conversion (PRUC) engine:
receiving, by said video decompression engine, compressed video data comprising a plurality of input pictures;extracting, by said PRUC engine, PRUC data from said compressed video data while said compressed video data is being decompressed by said video decompression engine, wherein extracting said PRUC data from said compressed video data comprises receiving said PRUC data from said video decompression engine, wherein at least a portion of said PRUC data is generated by said video decompression engine according to said compressed video data; andgenerating, by said PRUC engine, a plurality of interpolated pictures based on said PRUC data.
