Abstract

PURPOSE:To freely select a reproducing mode at the time of reproducing by fixing a recording mode, which does not miss any information, when video- recording high-vision television broadcasting signals. CONSTITUTION:Video and audio signals from a BS tuner part 11, video and audio signals from a U/V tuner part 12 and converted signals from a MUSE/ NTSC conversion part 13 are guided to a recording/reproducing deck part 14. When the signal of an aspect ratio 16:9 comes, the recording/reproducing deck part 14 performs video recording while setting a video recording mode to a squeeze mode so as not to miss any information. The output of the deck part 14 is passed through a picture mode conversion part 15 so as to freely select the picture mode (such as a non-conversion mode, wide mode or zoom mode) at the time of reproducing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television signal recording / reproducing apparatus which is useful as a built-in video tape radar (hereinafter referred to as VTR).

[0002]

2. Description of the Related Art In recent years, a system for transmitting and receiving a high-definition signal capable of obtaining a horizontally long screen (aspect ratio 16: 9) as compared with a screen (aspect ratio 4: 3) of a current type television signal has been developed. ing. In accordance with such a difference in television signal, it is necessary for VTR to take measures for recording method and reproducing method.
In the conventional VTR system, the screen mode is set and recorded in advance in consideration of the reproduction.
As the screen mode, normal mode, squeeze mode,
There is a wide mode, and when performing timer recording, either mode is set in advance. However, this is inconvenient to handle, and when a high-definition broadcast signal is recorded in the zoom mode, left and right information is lost and recorded, and important parts may not be seen later.

[0003]

As described above, in the conventional VTR system, various recording modes have to be selected, and handling mistakes are likely to occur. Moreover, if a high-definition broadcast signal is recorded in the zoom mode, information is recorded. There is a problem that the video is missing and recorded.

Therefore, according to the present invention, when recording a high-definition broadcast signal, the recording mode without loss of information is fixed, and the reproducing mode can be freely selected at the time of reproduction so that the user can view the image in his favorite state. It is an object of the present invention to provide a television signal recording / reproducing device which has been described above.

[0005]

The present invention has means for recording a high-definition broadcast signal in a fixed squeeze mode, and when reproducing and outputting this recorded signal, the reproduced signal The zoom mode, wide mode,
The squeeze mode processing unit includes means for selectively processing and outputting.

[0006]

By the above means, the information can be stored in the recording medium without loss of information, and the reproduced image can be obtained in the desired mode at the time of reproducing.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, which is 100
Is a video tape recorder (VTR) body, a BS tuner unit 11 capable of receiving satellite broadcast signals, and a U / V tuner unit 12 capable of receiving UHF and VHF band broadcast signals.
Have. The video and audio signals of the BS tuner section 11 are guided to the recording / reproducing deck section 14 for recording / reproducing.
MUSE (Mulitiple Sub-nyquist Sampling Encoding)
The MUSE signal obtained when the signal is received is MUS
MUSE / N that converts E system signals to NTSC system signals
It is guided to the TSC system conversion unit 13. MUSE / NTSC
The NTSC signal obtained by the format conversion unit 13 is guided to the recording / reproducing deck unit 14. The recording / reproducing deck section 14 has a U / V
Video and audio signals from tuner 12 are also introduced. The recording / playback deck 14 switches to the squeeze mode and records in this mode, particularly when an image signal with an aspect ratio of 16: 9 coming from the BS tuner 11 is selected.

When the video and audio signals from the U / V tuner section 12 are selected, and when the video and audio signals coming from the MUSE / NTSC conversion section 13 are selected, the normal mode, wide mode and zoom mode are selected. It is possible to select recording by. This selection can be made by the user.

The data is input to the screen mode conversion unit 15 reproduced by the recording / reproduction deck unit 14. This screen mode converter 1
In No. 5, the non-conversion mode, wide mode, squeeze mode, and zoom mode can be selected. The video and audio output terminals of the VTR configured in this way are
It is connected to the television receiver 20.

Next, the state of the recording screen of the above VTR,
The state of the reproduction screen will be described. This system is characterized in that when an image signal with an aspect ratio of 16: 9 is selected, it switches to the squeeze mode and performs recording in this mode.

The screen recorded in the squeeze mode is shown in FIG.
It is like a. The screen of the VTR corresponds to an aspect ratio of 4: 3. In the case of reproducing this, when the receiver having the aspect ratio of 4: 3 is provided and the non-conversion mode is set, it becomes as shown in FIG. Further, when the wide mode is set, it becomes as shown in FIG. That is, although a circular image is shown in the center of the screen, in the non-conversion mode, the image is reproduced in a compressed form in the horizontal direction, but there is no information loss. Further, when the image is reproduced in the wide mode, the left and right information is lost, but the circular image can be reproduced as a perfect circle without distortion. If you have a receiver with an aspect ratio of 16: 9,
If the image is reproduced in the non-conversion mode, a normal image can be displayed without distortion as shown by d in FIG.

As described above, when recording an image having an aspect ratio of 16: 9, by fixing the image in the squeeze mode, it is possible to record without loss of information, and it is possible to prevent recording error and to record at the time of recording. The complexity is lost.

The MUSE / NTSC converter 13 is normally adapted to obtain a signal converted into an image having an aspect ratio of 4: 3. When this signal is recorded, the signal e in FIG.
It is a recording screen like. When a receiver having an aspect ratio of 4: 3 is provided, the non-conversion mode results in a screen like f in FIG. 2 and the zoom mode results in a screen like g in FIG. Further, in the case where a receiver having an aspect ratio of 16: 9 is provided, when reproduction is performed in the zoom mode, it becomes as shown in FIG.

[0015]

As described above, according to the present invention, when recording a high-definition broadcast signal, the recording mode without information loss is fixed, and the reproducing mode can be freely selected at the time of reproduction, and the desired state can be obtained. Can be seen at.
