Reconstructing Efficiently Encoded Video Frames in a Distributed Video Coding Environment

摘要

Systems and methods are presented for reconstructing sequences of video frames received from a sending device in a distributed video coding environment. Some of the video frames are received as key video frames fully encoded at the sending device. Others are received as non-key video frames partitioned into pixel blocks. Some of the pixel blocks are indicated for reconstruction via a corresponding previous pixel block of a previous video frame, while other pixel blocks are to be reconstructed by decoding encodings of those pixel blocks received from the sending device. Each received encoding of a pixel block is based on contents of the non-key video frame that contains the pixel block and not on contents of the previous key video frame, nor on contents of any other video frame positioned between the previous key video frame and the non-key video frame in the sequence of video frames.
