Abstract
In the case where plural encoder outputs are encoded at variable bit rates and are multiplexed to carry out transmission thereof at a fixed or constant bit rate, the output bit rates from respective buffers are controlled on the basis of delay time &tgr; from the time when encoding bit rates of video signals Video , Video of the respective encoders have been changed. Thus, the multiplexed bit rate is prevented from exceeding the capacity of the transmission path or causing an overflow of an encoder buffer.
