Abstract

PURPOSE:To control optionally operations of video and audio fade-in and fade- out, etc., by controlling the operation of a video tape recorder (VTR) with the reproduced signal of the VTR and recording the signal sent from a video camera to the VTR. CONSTITUTION:A video monitor device 22, an audio monitor device 23 and a decoding circuit 24 are connected to a video signal output OUT1 and an audio signal output OUT2 and a terminal OUT3 of a VTR 21, respectively. The circuit 24 converts a self-control signal into a digital signal. A microcomputer 25 controls a video camera 30 in response to the information shown by the digital signal. At the same time, an illumination control circuit 26 and camera position control circuit 27 and 28 are controlled in response to the self-control signal to control the tone of color, chroma, lightness, iris, video zoom, audio zoom, focus, shooting angle, etc.

The present invention has been made in response to the following two problems, and includes a video tape recorder device, a video camera device J consisting of a video camera and its related restriction circuit, and uses the V11 signal of the video tape recorder device. The I/C mechanism 1 is configured to record the signal from the video camera to the -IJ video recorder device by controlling the RJ+A operation of the video camera device, thereby removing the conventional faulty fire. The purpose is to provide 1゛v synudem. Below drawings ￥h ＋
The J style of the present invention will be explained using t(t).

? Figure 1 is a block diagram showing a video tape recorder device (hereinafter referred to as the VT it device) used in the self-control V system according to the present invention.
The storage device 21 is equipped with a human power input terminal INl for voice signals, an input terminal 1112 for a control signal (self-control signal), and an input terminal IN5i for a video signal 1d.

The audio signals, self-control ID numbers, and video signals are recorded on 91 trunks of video tape, each of which can be dedicated to multiple channels. The self-control signal is a signal for controlling the operation of the video camera and its PA sub-control circuit, and is recorded in advance on a predetermined trunk of the video tape.

Figure 2 shows 11'C on the track where each of the above signals is specified.
