Abstract

PURPOSE:To shorten the transmission time in comparison with a conventional system to transmit data in more real time by inserting change data of data to be transmitted between time slots of reference data, which is transmitted at intervals of a prescribed time, based on reference data transmitted before this data and transmitting this change data. CONSTITUTION:A frame including reference value data is transmitted as every n-th frame. The frame including reference value data includes a 40-bit synchronizing word and n-number of 40-bit words. The frame which does not include reference value data includes the 40-bit synchronizing word and n/2-number of 40-bit words. The frame following the frame including reference value data has data where increase of reduction from reference value data is indicated with a sign (one bit) and the variation is expressed with three bits, and the frame following this frame has data where increase or reduction from the corresponding data part of the preceding frame is indicated with the sign (one bit) aud the variation is expressed with three bits.
