In most standards, the rate control scheme, which plays an important role in improving and stabilizing the decoding and playback quality, is not defined, and thus different strategies can be(More)
The rate control algorithm plays an important role for improving and stabilizing the playback quality for video coded with the MPEG standard. Several optimal control techniques have been proposed to aim at the best possible quality for a given channel rate and buuer size. Some of these approaches are complex in that they require the rate and distortion(More)
