Description

VTR with automatic TV reception

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape recorder (hereinafter referred to as a VTR). More particularly, the present invention relates to a TV receiver that allows a user to watch a TV instead of a VTR when a specific program of the TV starts during the operation of the VTR. It relates to a VTR with an automatic switching function.

In general, the VTR refers to a device for recording or reproducing a television image signal on a magnetic tape as a recording medium. The recording head and the reproduction head are arranged on the circumference of the cylinder, so that scanning is performed by the rotation of the cylinder. At right angles to the rotation direction, the rotation direction of the cylinder corresponds to the horizontal scan and the progression of the tape corresponds to the vertical scan.

The advantage of the VTR is that there is no need to convert an image signal into an optical image like film recording, so that there is no loss or distortion due to the optical system or the developing process, and since the developing process is unnecessary, the VTR can be reproduced immediately after recording.

Referring to Figure 1 attached to the configuration of the VTR having the above advantages, the antenna 1 for receiving the airwave broadcast signal, and the broadcast signal connected to the antenna 1 and received according to the control signal A broadcast receiver 10 for amplifying an intermediate frequency (IF) signal of a tuned broadcast signal and outputting a video and audio signal, and a video signal output from the broadcast receiver 10 for recording on a videotape; A video signal recording / recording method for recording a modulated signal output from the FM modulating circuit 20 according to a control signal and an FM modulating circuit 20 for modulating the signal on a video tape VT, and reproducing and outputting the recorded video signal. FM demodulation circuit 40 for demodulating the video signal output from the playback section 30 and the video signal recording / reproducing section 30 in the original form, such as the video signal output from the broadcast reception section 10; , F A video amplifier 50 for amplifying the video signal output from the M demodulation circuit 40, an RGB color signal and a Y signal for displaying an image according to a control signal, and a signal output from the video amplifier 50; An image processor 60 for generating a horizontal / vertical synchronization signal, a microprocessor 70 for generating control signals for overall system operation according to an operation signal generated from the front panel 110 or a remote controller, and the microprocessor OSD outputs predetermined OSD (On Screen Display) pattern data corresponding to the control signal in accordance with the predetermined control signal output from the 70, thereby informing the user of major operating conditions such as channel switching or volume adjustment. The generation unit 80, the image processing unit 60 and the OSD generation unit 80 receives the data generated from the image to be displayed on the CRT to apply to the CRT And an image forming unit 90.

On the other hand, the video signal recording / reproducing section 30 includes a recording amplifier 31, a preamplifier 32, a head HD, and a mode switching switch SW for recording / reproducing.

The above configuration is a schematic diagram for briefly explaining the operation of the VTR. When the operation is briefly described, the user manipulates key metrics (not shown) on the remote controller or the front panel 110 to convert broadcast recording or reproduction of the recording into an electrical operation signal. Upon request, the microprocessor 70 receiving the operation signal generates a control signal to control the broadcast receiver 10 in the recording mode to tune the broadcast, and the tuned broadcast signal is video through the FM modulator circuit 20. The signal SW is modulated into a signal that can be recorded on the tape VT, and the switch SW in the video signal recording / reproducing section 30 is connected to the contact a to perform recording.

On the other hand, when the recorded contents are to be displayed, the microprocessor 70 connects the switch SW to the contact b to reproduce the recorded contents, and the recorded video output from the video signal recording / reproducing section 30. The signal is demodulated in the form of an original video signal like the video signal output from the broadcast receiver 10 by the FM demodulation circuit 40 and input to the image processor 60 through the video amplifier 50.

At this time, when the user adjusts the volume or performs other operations, the microprocessor 70 receiving the operation signal corresponding thereto generates OSD data by applying a control signal corresponding to the operation signal to the OSD generator 80. The image signal generated by the image processor 60 and the OSD data are mixed by the image forming unit 90 and displayed on the CRT.

According to this configuration, when a user watches a video tape (VT) while waiting to watch a predetermined program on a TV, the playback time or recording operation of the VTR may be performed by not recognizing whether the start time of the TV program has elapsed and a part of the TV program may be deleted. There is a disadvantage that you can not watch.

Accordingly, an object of the present invention is to provide a VTR having an automatic TV reception function that allows a TV to be watched instead of the VTR when a specific program of the TV is started during the operation of the VTR. It is done.
