Innovative ultra low complex, high quality and drift free MPEG-2 transrater controlled by a single pass-very precise variable rate controller
F. Benussi, Danilo Pietro Pau, Viviana D'Alto · 2003
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.
