EQUIPMENT WITH DIGITAL INTERFACE AND METHOD FOR DIGITAL INTERFACING

摘要

An equipment and method for allowing synchronous dubbing and tag recording without using a large-capacity buffer memory. A reference signal from a cylinder servo circuit and tape driving servo circuit of a transmitter is converted into an isochronous packet and is outputted to a 1394 cable from a digital interface transmitting circuit. Then, a receiver converts the received isochronous packet back into a reference signal as it was before by means of an isochronous packet converting circuit, and then supplies it to the cylinder servo circuit and tape driving servo circuit. By this method, the transmitter and the receiver are synchronized and thereby synchronous dubbing and tag recording are made available. Signal regeneration by the transmitter and recording by the receiver are conducted at a timing based on the reference signal, and therefore there is no necessity of a buffer memory for time synchronization.
