1. A method for encoding video information including deriving prediction motion coefficients for blocks within a macroblock of a video frame being encoded from motion coefficients of at least one prediction block that is a previously encoded macroblock or block within said video frame, the method comprising:

  • segmenting the video frame into macroblocks;

    defining a certain number of available macroblock segmentations that specify possible ways in which a macroblock can be segmented into blocks;

    defining for each available macroblock segmentation at least one available prediction method thereby providing a certain finite number of available macroblock-segmentation—

    prediction-method pairs, each prediction method defining a method for deriving prediction motion coefficients for blocks within a macroblock using motion coefficients of at least one prediction block;

    selecting for a macroblock one of the available macroblock-segmentation—

    prediction-method pairs; and

    segmenting the macroblock into blocks and deriving prediction motion coefficients for the blocks within said macroblock using the selected macroblock-segmentation—

    prediction-method pair.
