Abstract :
A novel method to change the bit-rate of MPEG-2 video streams is proposed. It is based on an adaptive quantizer and single-pass variable rate controller. It achieves better quality, without being affected by drift degradation. A software low power implementation is proposed on a powerful SLIW DSP//spl mu/P.
