CODED SIGNAL TRANSMISSION METHOD AND DEVICE

摘要

In the case where a plurality of encoder outputs coded at a variable bit rate are to be multiplexed and transmitted at a constant bit rate, the output bit rate from each buffer is controlled on the basis of a delay time tau 1 from the time when the coding bit rate of video signals Video1, Video2 of each encoder changes until the output bit rate of the buffer changes. Thus, the multiplexed bit rate may be prevented from exceeding the capacity of a transmission line, and overflow of the encoder buffer may be prevented from occurring.
