Transmission and reception of control signals and response signals are made through bidirectional communication lines between a control device and a reproducing VTR and between the control device and a recording VTR to measure rise-up times D1 and D2 of mechanical systems of the reproducing VTR and the recording VTR. Thereafter, the tapes of the reproducing VTR and the recording VTR are rewound from their editing points by a predetermined time T, and then kept to a pause state. Subsequently, when a nominal time X for releasing the pause of the reproducing VTR and the recording VTR is specified, the reproducing VTR and the recording VTR actually receive the control signal to release from pause at a time of X-D1 and a time of X-D2 respectively, and the recording VTR is so controlled as to start its recording operation at a time of X+T.

1. Field of the Invention
This invention relates to a method and apparatus using a computer to control editing on video equipment, audio equipment, etc. (hereinafter referred to as "AV devices").
2. Background of the Invention
FIG. 1 is a block diagram showing the construction of a control system to which an embodiment according to this invention is applied;
FIG. 2 is a block diagram showing the construction of a control unit group of a first VTR in the control system as shown in FIG. 1;
FIG. 3 is a block diagram showing the construction of another control system to which an embodiment according to the present invention is applied;
Preferred embodiments according to this invention will be described hereunder with reference to the accompanying drawings.
FIG. 1 is a block diagram showing the construction of a control system to which an embodiment of this invention is applied.
The control system includes a control device 1 such as a personal computer (PC) or the like, a first VTR 2, a second VTR 3, a first monitor 4, and bidirectional communication lines 5, 6 and 7. The control device 1 transmits various control signals through the bidirectional communication lines 5, 6 and 7 to the first VTR 2, the second VTR 3 and the first monitor 4, and each of the first VTR 2, the second VTR 3 and the first monitor 4 transmits a response signal for the control signal to the control device 1. The communication operation as described above is carried out on the basis of VISCA.
