The device comprises a plurality of circuits interfacing a computer with a plurality of professional videorecorders, for the automatic control by computer of all the operations carried out by the video-recorders. Each of the interface circuits requests of the computer only data allowing its addressing, data identifying an image sequence on which the video-recorder must operate and data on the kind of operation to carry out, and comprises a logic circuit, which is capable of shortening the time taken by the videorecorder to search for the sequence and determines the direction and the speed of the magnetic tape depending on the determination of the position of the point being read on the tape with respect to the sequence position, and a further circuit able to detect errors of data setup by the computer and errors due to data misinterpretation by the videorecorder.
