VARIABLE BIT-RATE ENCODER

摘要

The invention relates to a process for coding digital data of a video sequence for its transmission and a variable bit rate.It is characterized in that the bit rate regulation in respect of the image at the instant n is performed as a function of a bit rate prediction in respect of the transmission channel for the instant n+&tgr;, &tgr; being a constant time between the instant of storage of an image in the buffer of the coder and the instant of output of this image from the buffer of the decoder.
