1. A system comprising:

  • means for initializing an accumulated bandwidth record;

    means for encoding a first frame of the motion video signal to form an encoded frame;

    means for determining a consumed bandwidth of the encoded frame;

    means for adjusting the accumulated bandwidth record according to the consumed bandwidth;

    means for comparing the accumulated bandwidth record to a desired range of acceptable accumulated bandwidth;

    means for adjusting a quantization parameter such that encoding subsequent frames of the motion video signal according to the quantization parameter as adjusted consumes bandwidth in a manner which compensates for a deviation from the desired range of acceptable bandwidth by the accumulated bandwidth record; and

    means for encoding a second frame of the motion video signal according to the quantization parameter as adjusted.
