Encoder/decoder buffer control for variable bit-rate channel

摘要

Encoder/decoder buffer overflow and underflow encountered when employing actually variable or effectively variable bit-rate channels (101) for communicating encoded video images and corresponding audio signals are overcome by adjusting the parameters of a video encoder (in 100) in response to to a representation (Jdec) of cell delay variation, i.e., jitter, determined at a remote decoder (in 102).
