Abstract:
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.
