Abstract

PURPOSE: To provide a remote control system which makes video images watchable using a TV by an easy operation by a method wherein, when a VTR remote controller turns-on the power source of a VTR, the controller turns-on the power source of the TV and sends a signal to switch the TV mode to the video mode. CONSTITUTION: A VTR 1 has microcomputers 16 and 14 for VTR- and TV control and, when a remote controller 18 is operated, a remote controlled photo- receiving section 17 receives a signal from the controller 18 and a microcomputer 16 turns-on the power source. Next, an antenna TV/VTR changing switch 6 sets transmission data T, depending on the judgement whether the RF modulator 8 is CH1 or CH2 from the side of a VTR-side terminal 6b. And by setting the data which turns on TV2 on the transmission data T using a microcomputer 14, a TV controller 26 is made to produce light, which is received by a photo- receiving section 23. This signal turns-on the power source of TV2 and the microcomputer 24 sets the tuner section 20 to convert the TV mode to the video mode. By this, video images are automatically watched using TV2 by a simple operation.

A VTR remote control light receiving unit 17 is connected to the input side of the R control microcomputer 16, and the remote control light receiving unit 17 receives a signal from the remote control 18.

On the other hand, the tuner section 20 of the TV 2 has an RF input terminal 21, and the tuner section 20 is connected to a CRT 22. Further, the TV remote control light receiving unit 23 is provided on the TV 2.
The light receiving section 23 is connected to the tuner section 20 via a microcomputer (microcomputer) 24.

The connection between the VTR 1 and the TV 2 thus configured is such that the RF output terminal 7 of the VTR 1 and the antenna input terminal 21 of the TV 2 are connected by the coaxial cable 25 and the TV controller connected to the TV control terminal 15 of the VTR 1. 26 is arranged in the vicinity of the remote control light receiving unit 23 of the TV 2.

Next, the operation of reproducing the video image of the VTR on the TV 2 will be described with reference to the flowchart on the VTR side shown in FIG. 2 and the flowchart on the TV side shown in FIG.

First, the operation on the VTR 1 side will be described with reference to FIG. First, in step S1, VTR1
It is determined whether or not the power supply of has been turned on. By operating the remote controller 18, a signal from the remote controller 18 is received by the remote controller light receiving unit 17, and the VTR control microcomputer 16 turns on the power of the VTR 1. If the power is on, the process proceeds to step S2, where it is determined whether the antenna TV / VTR switch 6 is on the VTR side terminal 6b side, and if so, the process proceeds to step S3 where the channel of the RF modulator 8 is CH2. If it is CH2, it is determined whether or not it is present. In step S4, the signal of CH2 is set in the transmission data, and then the process proceeds to step S6. If the channel of the RF modulator 8 is CH1, the signal of CH1 is set in the transmission data in step S5, and the process proceeds to step S6.

In step S6, the data for turning on the TV2 is set as the transmission data in the TV control microcomputer 14, and the data signal is emitted from the TV controller 26 in the tape S7.
