Abstract

Encoder/decoder buffer overflow and underflow encountered when employing actually variable or effectively variable bit-rate channels for communicating encoded video images and corresponding audio signals are overcome by adjusting the parameters of a video encoder in response to a representation of cell delay variation, i.e., jitter, determined at a remote decoder.
