Abstract
In a multiplexing system wherein data from a plurality of terminal units are multiplexed in time slots shared to the terminal units and coded picture data are multiplexed at least in time slots shared for picture, there are provided picture signal encoding means operating at a clock frequency independent of a clock frequency for a transmission path, a buffer memory circuit for storing the coded picture data outputted from the picture signal encoding means, a data detecting circuit for detecting presence or absence of output data from the plurality of terminal units and a multiplexing circuit which shares coded picture data read out from the buffer memory circuit to a time slot or time slots of terminal units whose output data are not detected by the data detecting circuit and which shares, to time slots of terminal unit whose output data are detected by the data detecting circuit, output data of these terminal units, thereby adaptively sharing coded picture data to the time slots for the terminal units.
