(a) Each block () in the sequence has different R-D characteristics (for a given set of quantizers () for blocks in the sequence, R-D (rate-distortion) points (, , and , , , etc.) can be obtained to form composite characteristics); and (b) R at is not a feasible solution to the selected maximum buffer size .
