Data multiplex recorder and data reproducing device

Abstract

Abstract PURPOSE:To record the video signal onto a laser disk or the like similarly to the case with a conventional video signal by using a data and interleaving and multiplexing the result onto the video signal for a prescribed horizontal synchronization period in a vertical blanking period. CONSTITUTION:A data fed to a frame cut-off circuit 5 is cut off for a timing corresponding to each line of lines No.12-15 or No.275-278 based on a timing signal from a timing signal generating circuit 4 and fed to a multiplexer circuit 6. Then the data from the frame cut-off circuit 5 is multiplexed on the video signal in the multiplexer circuit 6, from which the multiplexed signal is outputted. The video signal multiplexed with the playing information is recorded on a laser disk similarly to the case with a conventional video signal.
