Patent Images

1. A method for a video encoder to encode data from a set of image blocks, each block being associated with a frame, a counter value and a cost, the method comprising:

  • for a target block of the set of image blocks, calculating the respective counter values and the respective costs of other blocks from among said set of image blocks, wherein;

    said other blocks are associated with the same frame as the target block or with a previous frame; and

    said other blocks neighbor the target block or are located in a same position as the target block in the previous frame;

    when at least one of said other blocks satisfies a predetermined criteria;

    selecting from the other blocks a reference block having the lowest cost and counter value according to the predefined criteria;

    encoding predicted data for the target block based on the reference block;

    when at least one of said other blocks does not satisfy the predefined criteria, encoding unpredicted data for the target block;

    wherein transferring the encoded predicted data for the target block consumes less bandwidth than transferring the unpredicted data for the target block.
