Reproducing device of video signal

Abstract

Abstract PURPOSE: To make high-speed search possible, by synthesizing reproducing signals after distributing and store them to respective channels in the helical scan multitrack system digital VTR. CONSTITUTION: The signal obtained by digitizing the video signal is distributed to plural channel by every prescribed number of bits, and identification signal ID and address signal AD are added for every prescribed number of bits in each channel, and signals of respective channels are recorded as oblique tracks 3A∼3C on tape 2 by rotary heads 1A∼1C respectively, and this tape 2 is reproduced. At this time, tape 2 is caused to run in a speed higher than that for recording, and signals ID are taken out from reproducing signals for every channel, and reproducing signals are distributed to original channels on a basis of these signals ID by multiplexers MUXa∼MUXc, and these signals are written to memories 34A∼34C according to signals AD, and read signals from these memories are synthesized in 36 to obtain digital signals of contents corresponding to the tape speed.
