VIDEO ENCODING WITH CONSTRAINED FLUCTUATIONS OF QUANTIZER SCALE

摘要

During video compression quantizer scale values for respective blocks under control of a complexity of a content of image information. The temporal and or spatial fluctuations of the quantizer scale values are dampened, for example by low pass filtering provisionally selected quantizer scale values. The quanitizer scale values are use to quantize the video data. The quantizer scale values may also be used during transcoding.
