Abstract:
1. A method for signal processing, the method comprising: receiving, by a video transmitter, a compressed video bitstream comprising a plurality of video frames; generating, by the video transmitter, frame-rate up-conversion coding information from the video bitstream for frame-rate up-conversion of the plurality of video frames by a video receiver; and transmitting, by the video transmitter over a wireless transmission link, the plurality of video frames and the corresponding frame-rate up-conversion coding information to the video receiver for performing frame-rate up conversion by the video receiver for the plurality of video frames using the generated coding information, wherein the performing of the frame-rate up conversion comprises: generating pixel motion vectors using at least one of block motion vectors or block coding modes comprised in the generated coding information for a plurality of decoded video frames; and computing a motion vector confidence, a motion vector consistence, or both for the corresponding generated pixel motion vectors, the motion vector confidence being computed using at least one of a quantized residual data or a quantization level comprised in the coding information, the motion vector consistence being computed by comparing adjacent block motion vectors and motion-compensated block boundary pixel differences.
