Abstract

(57) [Abstract] [Purpose] In a television receiver with a built-in VTR, in which the reception signal (back program) of the second broadcast receiving device is recorded on the VTR while the reception signal of the first broadcast receiving device is viewed on the display device. , The receiving screen of the first broadcast receiving device that is necessary for memo,
The above-mentioned VT can be recorded without damaging the recording of the back program when necessary.
A specific configuration for recording in R is provided. [Structure] The reception signal of the first broadcast receiving device 11 being viewed on the display device 15 is always phase-synchronized with the reception signal of the second broadcast receiving device 12 by the TBC circuit 16, and the operation switch 17 is operated when necessary. The changeover switch 19 is switched in response to the operation of 1 to replace only the one-frame signal of the TBC circuit 16 with the one-frame received signal of the second broadcast receiving apparatus 12 and record it in the VTR 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing device (hereinafter referred to as a VTR), a first broadcast receiving device for receiving a television broadcast, and a second broadcast receiving device for receiving a television broadcast for recording on a VTR. The present invention relates to a television receiver with a built-in VTR, which comprises a broadcast receiving device and a display device for selectively displaying an output signal of the VTR and, in particular, a signal of the second broadcast receiving device. While recording on the VTR,
The present invention provides a specific configuration for recording the signal of the first broadcast receiving device viewed on the display device on the VTR as a still screen.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing an example of a conventional television receiver with a built-in VTR, 11 is a first broadcast receiving apparatus for receiving a television broadcast, and 12 is a television receiver for recording the television broadcast. A second broadcast receiving device, for receiving
Reference numeral 13 is a VTR, 14 is a switch for switching the output signal of the first broadcast receiving device and the VTR, and 15 is a display device such as a picture tube.

When watching television, the signal of the first broadcast receiving device 11 is displayed on the display device 15. VTR13
Since the signal of the second broadcast receiving device 12 is used for recording in, the signal of the broadcast station different from the signal of the broadcast station viewed by the first broadcast receiving device 11 can be recorded. it can. When the playback signal of the VTR 13 is viewed, the signal changeover switch 14 is used to display the V
Connect the output signal of TR13.

[0004]

However, according to this configuration, the screen of the first broadcast receiving device 11 displayed on the display device 15 while the signal of the second broadcast receiving device 12 is being recorded by the VTR 13 is displayed. For example, if video information such as a cooking ingredient list or a telephone number for inquiries is to be recorded, the reception channel of the second broadcast reception device 12 is changed to be the same as the reception channel of the first broadcast reception device 11. However, there is a problem that the originally recorded video information is interrupted.

[0005]

In order to solve this problem, a television receiver with a built-in VTR according to the present invention uses a VTR, a first broadcast receiving device for receiving a television broadcast, and a television broadcast as a VTR. In a television receiver with a built-in VTR, which comprises a second broadcast receiving device for receiving for recording, the first broadcast receiving device and a display device for selectively displaying the output of the VTR, While the signal of the device is being recorded in the VTR, the signal of one screen of the received signal of the first broadcast receiving device is replaced with the signal of one screen of the second broadcast receiving device in response to the operation of the operation switch. And recorded on the VTR.

[0006]

In the related art, by having the first and second broadcast receiving devices, the signal from the second broadcast receiving device different from the signal from the first broadcast receiving device viewed on the display device is recorded. It was possible to record a back program, but in order to record the program that was being viewed while recording the back program, the currently recorded program had to be interrupted and the channel changed and recorded. .

According to the above-mentioned configuration of the present invention, the input signal of the VTR recording the signal from the second broadcast receiving device is switched to the signal from the first broadcast receiving device, and the image signal of one screen is displayed. By recording the recorded tape, it is possible to reproduce the image signal of the inserted one screen when the recorded tape is still reproduced, and when the normal continuous reproduction is performed, only the signal from the second broadcast receiving device is recorded. Played as if it had been.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a main part of a first embodiment of a television receiver with a built-in VTR of the present invention. The same components as those in the conventional example of FIG. 2 are designated by the same reference numerals. The difference between this embodiment and the conventional example is that the TB having a conventionally known configuration is used.
The C (time base collector) 16 constantly converts the received signal of the first broadcast receiving apparatus 11 into a signal in phase with the received signal of the second broadcast receiving apparatus 12, and the operation of the operation switch 17. Accordingly, the switching signal generation circuit 1
A switching signal for a period of one frame synchronized with the vertical synchronizing signal of the received signal of the second broadcast receiving apparatus 12 is created by 8, and the switching switch 1 is operated by this switching signal.
9 is switched to the output side of the TBC 16 only for one frame period. That is, in response to the operation of the operation switch 17, the one-frame signal of the received signal of the second broadcast receiving device 12 is replaced with the one-frame signal of the received signal of the first broadcast receiving device 11, and the VTR 13 is used. It is configured to record.

Further, in order to facilitate the retrieval of the replaced and recorded position, a command signal for applying an index signal (not shown) having a conventionally known structure in synchronization with the switch signal is used as the switch signal. It is created by the creating device 18 and input to the VTR. As a result, when searching the insertion part of one screen, it is only necessary to search the index signal, so that the search can be performed quickly and easily. As a specific example of the index signal, the pulse width of the control signal recorded on the edge of the magnetic tape for each frame may be different from the pulse width during normal recording in response to the application of the command signal. It is good to configure it.

[0010]

As described above, according to the present invention, the input signal of the VTR which records the signal from the second broadcast receiving apparatus is switched to the signal from the first broadcast receiving apparatus, and one screen is displayed. By recording the image signal, one screen from the first broadcast receiving device can be inserted and recorded in the VTR being recorded,
When the recorded tape is played back still, the inserted image signal of one screen can be played back, and when the normal continuous playback is performed, only the signal from the second broadcast receiving device is played back. It is something.
