Abstract
An analog control signal with an index signal recorded in a first magnetic tape is reproduced in synchronization with the reproduction of an AV digital signal recorded in the first magnetic tape. The index signal corresponds to a leading position of the AV digital signal. When the index signal is detected, an index code is prepared, and the index code and the AV digital signal are packed in an isochronous packet. The index code corresponds to the leading position of the AV digital signal. The isochronous packet is transmitted to a recording VCR through a packet transmission line, and the AV digital signal extracted from the packet is recorded in a second magnetic tape. Also, when the index code of the packet is detected, a duty ratio of a specific group of pulses of a control signal generated in the recording VCR is changed to reproduce the index signal. Thereafter, the control signal with the index signal is recorded in the second magnetic tape while making the index signal correspond to the leading position of the AV digital signal. Therefore, even though any private line for an analog signal such as the control signal is not arranged, the control signal and the AV digital signal recorded in the first magnetic tape can be dubbed in the second magnetic tape.
