Abstract: A method of coding video content. The method can include, identifying a first plurality of image blocks within a picture based on at least a first image characteristic that is common to each of the first plurality of image blocks. A first image block group can be dynamically defined. At least one of the image blocks can be selected as a predictor block to predict other image blocks within the first image block group. In another arrangement, at least a first image block and a second image block can be identified within a picture. The second image block can be predicted from the first image block. A displacement vector can be defined to associate the second image block with the first image block. A value representing the displacement vector can be included within a header of the second image block.

Abstract: A first video signal processor (103) receives a first encoded video signal from which a video unit (201) generates a second encoded video signal, where the second encoded video signal is a reduced data rate version of the first encoded video signal. An error encoder (203) generates error redundancy data for the second encoded video signal and a multiplexer (207) generates output video data comprising the first encoded video signal and the error correcting data but not comprising the second encoded video signal. A second video processor (105) receives the output video data and a video unit (303) regenerates the second video signal from the first video signal. An error unit (305) detects errors for at least a first segment of the second video signal in response to the error redundancy data. A combiner (307) then generates combined video data by combining corresponding segments of the first encoded video signal and the second encoded video signal.
