ABSTRACT:
Signal sources provide frames (302-303) to a comparator (206). For each frame, codeword error statuses for each of the codewords and a frame error status (313-314) are determined. Codeword error statuses are provided for priority sets of codewords (306, 308) and are not provided for non-priority sets of codewords (311, 312). The codeword error statuses for members of the priority set of codewords for each frame are compared, wherein the members have substantially identical codeword identifications. Selected priority codewords are produced by selecting members of the priority sets having favorable codeword statuses. Furthermore, the frame error statuses for each frame are also compared. Selected non-priority codewords are produced by selecting the non-priority set of codewords corresponding to a favorable frame error status. The selected priority codewords and the selected non-priority codewords are then provided as the favorable signal representation (304). Alternatively, only frame error statuses may be provided.
