Abstract
A light-signal transfer apparatus capable of continuously reproducing signals even if the transfer passage is temporarily intercepted, the apparatus being structured in such a manner that a delay memory delays time-sequential digital data to generate digital data, a multiplexer multiplexes two digital data items to transfer the data items as infrared rays. An error correction circuit corrects the transmitted signals to output multiplexed data and outputs error detection signal indicating a fact that correction cannot be performed because of interception of the transfer passage or the like. A demultiplexer separates transmitted multiplexed data into two digital data items, and a delay memory delays one of the digital data items to make coincide the time bases of the two data items. A data selector selects either of the two digital data items in accordance with information of the error detection signal.
