Abstract:
A method for encoding a sequence of video frames, said method comprising:receiving the sequence of video frames; for each video frame from the sequence of video frames: dividing the video frame into a plurality of macroblocks; encoding each of the plurality of macroblocks using at least one of an intraframe mode (I-mode) technique and a prediction mode (P-mode) technique, and for said video frame, at least one macroblock is encoded using an intraframe mode technique and at least one other macroblock is encoded using prediction mode technique wherein the P-mode technique generates at least n+1 prediction error signals for each of the plurality of macroblocks, where n represents a number of channels; and providing both the I-mode technique encoded data and the at least n+1 P-mode technique prediction error signals to each of the n channels, wherein each of the n channels are used to transmit the encoded plurality of macroblocks.
