PURPOSE: To reduce the sampling rate and the quantity of used hardware at the time of transmitting information signal samples obtained from a plurality of channels. CONSTITUTION: Decoders 22R, 22G, and 22B transmit the signal samples of a plurality of channels supplied to inputs 16, 18, and 20 by alternately selecting the samples. The decoders 22R, 22G, and 22B also select the direction in which the variation amount of sample pairs is the smallest among transmitting directions around the alternately left samples and transmit control signals (SM) indicating the selected direction. On the receiving side, complete information signals are reproduced, together with the transmitted signals by reconstituting the alternately left samples of the transmitted signal samples and control signals. |
