Patent

CA 1333420

The present invention relates to a multimedia data transmission system. The system is comprised of a unit for configuring transmission frames of 80 x L (where L is a natural number) bit lengths having the repetition frequency of 100 Hz uniformly collecting 80 basic time slots. The time slots are specified without relation to the transmission rate, of L bit lengths and have a repetition frequency of 8 kHz corresponding to the transmission rate of 8 x L Kbps. A unit is also provided for configuring a multiframe by uniformly collecting 16 transmission frames without relation to the transmission rate. A multiplexer is provided for multiplexing multimedia data, in every of the basic time slots, transmission frame or multiframe, such as encoded video data or encoded voice data having a code transmission rate which is, for example, an integer time of 8 Kbps or matching said transmission frame or multiframe. A communication control unit is provided for notifying the receiving side by arranging a synchronous code for identifying partition of the transmission frame and multiframe and a bit assigning information for indicating bit assigning of multimedia data to a predetermined bit in the basic time slot.
