ABSTRACT:
A rate controlled VBR quantizing system includes a quantizer for quantizing partially compressed video data and further apparatus for monitoring the amount of compressed output data. Dependent upon the amount of compressed output data being lesser or greater than a predetermined value, the quantizer is conditioned to operate in a fixed quantization mode, or a mode wherein only selected blocks of data in respective frames are adaptively quantized, respectively.
