Low-power DV encoder architecture for digital CMOS camcorder

Design and implementation of a real time high quality DV digital video software encoder

“…The brute force approach is to try all possible quantization scales, perform variable length encoding on them and take the best-fit quantization scale. But this approach is computationally very expensive in software and is commonly implemented using multiple processing units in hardware [4]. Solutions to these problems along with descriptions on the other portions of the codec are discussed in the rest of the paper.…”
