Title: Stereo signal coding device
Inventor: TOMITA YOSHIHIRO
IPC: H03M3/04
Filed: 1988-03-11
Abstract: PURPOSE:To code the voices in number of bits proportional to the quantity of produced information by using an ADPCM coding device which codes the sum signal and the difference signal among channels independently of each other and varying the number of bits of the sum signal based on a fixed number of bits and the difference signal in accordance with the total number of produced signals respectively. CONSTITUTION:The electric power of the difference signal obtained by a subtractor is calculated by a bit control part 5 and the number of bits is obtained from the electric power level of the difference signal. The information on the obtained number of bits is given to a 2nd bit number variable ADPCM coding device 4. The device 4 applies the ADPCM processing to the difference signal based on said number of bits. The processed difference signal is multiplied by the ADPCM coded code of a sum signal and the bit number information via a multiplexing part 6 and transmitted to a transmission line. In other words, the sum signal is coded in a fixed number of bits and the difference signal is coded with variation of the number of bits performed in accordance with the number of produced signals. Thus it is possible to transmit the stereo signals of high quality in the number of bits proportional to the quantity of produced information varying in the lapse of time.
