Abstract

PURPOSE:To increase the transmission efficiency, by taking synchronism for multi- plexed frame without using a frame synchronizing signal pattern. CONSTITUTION:As an output code from a coder encoding a digitized video signal for redundancy compression, code assignment is executed in which only specific bit position (mark bit) has the probability of production of ''1'' being >=1/2. As multiplex frame, the frame constitution only consisting of output code information of a coder for each channel is used. The frame synchronism of a reception signal can be established with the combination of mark bit positions of each channel.
