Abstract

PURPOSE:To picture-record the program reserved at the time of the picture recording of the timer without fail by selecting the external input signal with the station selecting switch of the tuner and unifying the selecting system of the signal to one system. CONSTITUTION:At the time of the picture recording of the timer, when a timer, which can reserve the program, comes to be the picture recording starting time, a station selecting control signal is sent to a tuner station selecting circuit 5, it is selected whether the signal hoped by a TV tuner or a video input signal and the signal is inputted to a recording circuit system 4. Thereafter, the picture recording starting signal is sent from the timer 6 which can reserve the program, and the picture recording of the timer is executed. For the program to execute the picture recording at the time of the picture recording of the timer, either of the channel hoped by the TV tuner selected by a tuner station selecting circuit 5 or the video input signal is selected and picture-recorded.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a video tape recorder (hereinafter referred to as VTR).
The present invention relates to a magnetic recording/reproducing device such as, and particularly to a magnetic recording/reproducing device suitable for program reservation.

[Background of the invention]

Conventional VTRs are configured to switch between a TV tuner signal, a video input signal, and an audio input signal, as described in P2S5 of "Introduction to Home VTR" edited by the Television Society of Japan.

A conventional example regarding a video signal will be shown and explained below.

As shown in FIG. 1, a conventional VTR is comprised of a switching circuit 3 that switches between a TV chainer signal 1 and a video input signal 2. A video input changeover switch 7 selects a signal and sends the signal to a recording circuit system 4. It was entered. Therefore, during timer recording, a control signal is sent from the timer 6, which allows program reservation, to the tuner channel selection circuit 5 to select the program to be recorded.

However, if the video input selector switch 7 is configured to select the video input, even if the desired channel is selected on the tuner, only the video input signal is input to the recording circuit system 4, and the program you want to record is recorded. There was a problem that I couldn't do it.

[Purpose of the invention]

An object of the present invention is to provide a timer recording method that reliably records a reserved program during timer recording.

[Summary of the invention]

The gist of the present invention is that the external input signal can be selected by the tuner's tuning switch, and the signal selection systems are combined into one system.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. TV
It consists of a switching circuit 3 that switches between the tuner signal 1 and the video input signal 2, and the output signal of the switching circuit 3 is sent to the recording circuit system 4.
The tuner channel selection circuit 5 input to the TV tuner is configured to control the TV tuner signal 1 and the switching circuit 3, and the tuner channel selection circuit 5 is connected to a timer 6 that can reserve a program. The tuner selection circuit 5 is composed of two switches, one for up and one for down. Press the up button to select channels 1ch, 2ch, 3ch, etc. Press the down button to input video, 12ch,
Select channel 11ch... The tuner selection circuit 5 is
When selecting a channel, a tuning voltage necessary for each channel is supplied to the tuner, and a °L ° signal is supplied as a control signal to the switching circuit 3. Also, when selecting the video input, no tuning voltage is supplied to the tuner, and a °H" signal is applied to the control signal of the switching circuit 30. When the control signal is 'L°, the switching circuit 3 outputs the TV tuner signal. choose,
1771, selects the video input signal. Therefore,
The desired signal is selected by the switching circuit 5, and the recording circuit system 4
A signal is input to During timer recording, when the timer 6 that allows program reservations reaches the recording start time, a channel selection control signal (the same signal sent by the up/down button) is sent to the tuner channel selection circuit 5, and the desired signal of TV + Yuna is sent. or a video input signal, and the signal is input to the recording circuit system 4.

Thereafter, a recording start signal is sent from the timer 6 that allows program reservation, and timer recording is performed. According to this embodiment, the program to be recorded during timer recording is recorded by selecting either the desired channel of the TV tuner selected by the tuner channel selection circuit or the video input signal, so that the program is recorded by selecting the desired channel of the TV tuner selected by the tuner channel selection circuit or the video input signal. Since the switching and video input switching are independent, the video input switching will select the video input even if the recording channel is correctly selected, so even if you want to timer record a TV channel program, By selecting the video input, it is possible to prevent operational errors such as not being able to record TV channel programs.

In addition, if a timer that allows multiple program reservations is built in, the first program reservation records 2 channels of the TV channel, the second program reservation records the video input signal, and the third program reservation records the video input signal. Reservations can be made to record the TV channel t5ch. Therefore, if a power switch synchronized with this timer is built into the VTR, it is possible to timer record sound signals such as an FM tuner by supplying power to an external device such as an FM tuner when a video input signal is selected. can.

〔Effect of the invention〕

According to the present invention, since the program to be recorded during timer recording is selected by the tuner channel or external input signal, it is possible to record the desired program without fail. Furthermore, if you want to schedule recording of multiple programs, connect the external input signal and
This has the effect of being able to reserve the tuner signal alternately.
