2. Description of the Related Art In recent years, there has been an increase in the number of TV receivers with a built-in VTR in which a video tape recorder (hereinafter referred to as VTR) is built into a television (hereinafter referred to as TV) receiver.

This is to improve the operability, which was conventionally complicated, by combining two independent TV receivers and VTRs that are closely related to each other in the related art. For this purpose, the TV receiver has a built-in VTR and is integrated, and one operating device (for example, a remote control transmitter or device front operating unit) that has been present for each device until now is used for operating commands. The input system is collected in one.

The operation command given from the input system is divided by a TV tuning microcomputer (hereinafter, abbreviated as TV tuning microcomputer) for controlling the TV tuning according to the type of function to be operated. It is input to the receiver section and the VTR section to perform a functional operation.

The TV channel selection microcomputer uses a VTR system control microcomputer (hereinafter, abbreviated as VTR system microcomputer) for controlling the VTR system in order to determine the operation of the input function.
The status on the TR deck side is received by two-wire bidirectional serial communication.

On the other hand, in recent years, a wide screen (aspect ratio 1
6: 9) With the widespread use of the television system, the TV receiver itself also has a function of switching the aspect ratio, and has come to be compatible with a wide screen.
Also, the VTR has come to be compatible with a wide screen by outputting and inputting S1 video (aspect ratio 16: 9). Along with this, a function for supporting a wide screen has become necessary even in a TV receiver with a built-in VTR.

[0007]

However, in the conventional TV receiver or VTR as described above, in the VTR having the wide screen compatible S-VHS recording / playback function, it is selected to output the video output as S1 video. On the other hand, a wide screen compatible TV receiver (hereinafter abbreviated as a wide TV receiver) has a screen aspect ratio switching function. Therefore, when displaying an S1 video input, the aspect ratio is 16 : 9 can be switched, but since each device has an independent operating means, S1
When viewing a video tape on which an image is recorded on a wide TV receiver with an aspect ratio of 16: 9, the operation of each device must be manually set by each operating means in response to this case. Lost and the operation becomes complicated.

That is, on the VTR side, the output is set to S1 video output, and then it is connected to a wide TV receiver for reproduction, and on the wide TV receiver side, the TV screen is switched to the VTR input, Further, there is a problem that a very complicated operation such as setting the aspect ratio to 16: 9 is required.

The present invention relates to S1 recorded on a video tape.
A video tape device capable of reproducing an image and outputting an image based on the S1 image to a television screen with an aspect ratio adapted to the S1 image, and simplifying a setting operation when performing this operation. It is an object to provide a TV receiver with a built-in TV.

[0010]

In order to achieve the above object, a television receiver with a video tape device of the present invention has a function of reproducing a video signal recorded on a video tape and an image based on the video signal. A television receiver with a video tape device having a function of outputting to a screen detects a S1 video signal reproduced from a video tape and switches a control unit for switching an image on the TV screen to an aspect ratio adapted to the S1 video signal. Prepared for configuration.

[0011]

According to this structure, when the image based on the S1 video signal reproduced from the video tape is output to the television screen, the control unit displays the video based on the S1 video signal recorded on the video tape together with the S1 video signal. The identification signal is detected, and the image on the television screen is switched to the aspect ratio adapted to the S1 video signal.
