Abstract
PURPOSE: To suppress the overflow by giving the improvement to the format of the retransmission signal which is sent back via the backward channel for the signal transmission system with which the still picture can be transmitted effectively.
CONSTITUTION: Start signal ST used for the start-stop type synchronization is provided to the blocked data, along with the error block number composed of 11 bits and showing the number having some error, control bit C1 and C2 showing the presence or absence of the error for two blocks, and stop signal ST each. And these signals, number and bits are sent to the backward channel via shift register 28, decoder 27, FF29 and 30 plus gate circuit 31 and 32. Then the error numbers set in register 28 and the error information of the block numbers set to FF29 and 30 are delivered in sequence in the format, and the resetting is given via decoder 27, FF24 and counter 26 to stop production of the retransmission request signals.
