ABSTRACT:
Data multiplexing and demultiplexing apparatus for respectively timeshare-multiplexing a plurality of data signals and demultiplexing the timeshared-multiplexed data signals. The multiplexing apparatus includes a plurality of code buffers each respectively receiving one of the data signals, a control circuit for generating switching and header control signals, a switching circuit responsive to the switching control signal for successively retrieving each of the data signals from the code buffers and for grouping the retrieved data signals so as to form respective packets of data and for generating one or more packs of data from the packets of data each having a fixed data length, and a header adding circuit responsive to the header control signal for respectively adding a packet header and a pack header to each packet and pack. The multiplexing apparatus further includes a device for determining if the amount of data to be contained within each pack is less than that which may be contained therein and, upon such determination, for adding data thereto from another packet so as to fill the respective pack, The demultiplexing apparatus includes a header separating circuit for separating the pack and packet headers from the multiplexed data, pack time information storing circuit for storing time information included in each pack header, switching circuit for separating the multiplexed data into the original data signals, and a plurality of buffers each respectively storing one of the data signals from the switching circuit.
