AbstractThis paper proposes a new multimedia burst multiplex system for efficiently multiplexing such multimedia signals as speech and image on the digital channel. The performance is analyzed by approximation. The signals for each medium are encoded, put into packets, and stored in the buffer memory. The controller shared by media monitors the number of packets in the buffer memory as well as the maximum waiting time. The results are weighted for evaluation; and, according to the proposed rule, the packets are sent out to the line. By an approximate analysis, the proposed system is compared with FIFO and another system with priorities. It is seen that the proposed system, in terms of the performance, is in between FIFO and the priority systems. It can control and prioritize according to the property and state of the media, and is suited to multiplexing of media with various properties.
