The present invention relates to an audio equalizer level display device of a wide vision. More specifically, in a wide vision in which a large screen is configured in an enlarged mode of 16: 9 aspect ratio, an NTSC in which a screen configuration is performed in a standard mode of 4: 3 aspect ratio is performed. When displaying a broadcast signal of the type, wide television's voice can be eliminated by displaying the equalizer level according to the signal level of the voice broadcast signal for the remainder blanked on the screen. An equalizer display device is provided.

Usually, the aspect ratio of a video signal displayed on a television reproducing a broadcast program transmitted from a broadcasting station is set to 4: 3 ratio, but in recent years, a configuration having a higher aspect ratio by varying the aspect ratio of the video signal tends to be adopted. This is a trend to be strengthened.

An example of such a higher aspect ratio configuration is a 16: 9 aspect ratio (enlarged image mode) video system in which the 4: 3 aspect ratio (standard image mode) video signal is greatly expanded in the horizontal direction. Televisions with greatly expanded aspect ratios called 'id-vision' have been developed and used.

Such a wide vision capable of displaying an enlarged image (16: 9 aspect ratio) enables the display of a 4: 3 aspect ratio compatible display including a 16: 9 aspect ratio video signal. The multi-screen display function is possible by the water level 'PIP (Picture In Picture) mode' and POP (Picture Out Picture), which simultaneously display a plurality of screens in a video display device (CRT device).

However, in the case of watching a broadcast program or a video in a 4: 3 aspect ratio in a 16: 9 aspect ratio, an area in which the broadcast signal is blanked appears on the screen, and one screen is displayed even when the PIP or POP mode is specified. In the case where only the bay is additionally designated, a blanking area is generated, and thus, monotonous viewing occurs, and it is difficult to construct a realistic and realistic screen.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and equalizes the volume level according to the audio signal of a television broadcast in a blanked region of a screen generated during screen playback according to a 4: 3 aspect ratio in a wide vision with a 16: 9 aspect ratio. It is an object of the present invention to provide a wide vision audio equalizer level display device configured to display a screen in a form.

In order to achieve the above object, according to a preferred embodiment of the present invention, the standard mode and the PIP mode are set in a wide vision capable of selectively displaying images having different aspect ratios with respect to a video signal received through a tuner. A function setting means for detecting a sound signal from a plurality of frequency bands by detecting and analyzing an audio signal from an audio signal to be reproduced on a speaker, and an audio signal according to an area in which an image of a standard mode is reproduced on a screen. OSD graphic processing is performed for equalizer level data which analyzes the volume of the audio signal applied from the equalizer analyzing means while reproducing the image on the screen according to the mode selection of the synchronous detecting means and the function setting means for setting the equalization level synchronization. Control means for controlling the display to be displayed on the screen; A wide vision audio equalizer level display device is provided that includes an OSD processing means for OSD graphic processing an equalizer level, and positioning means for displaying the OSD processed equalizer level display at an appropriate position on a screen.

According to the wide-vision voice equalizer level display according to the present invention configured as described above, blanking is performed in which the standard mode is designated by the input means or the sub-screen is not reproduced according to the PIP or POP mode. The equalizer level is displayed at a predetermined position for each frequency band according to the volume characteristics of the voice signal reproduced in the area, eliminating the monotony generated in the viewing area by the blanking area on the screen, and the screen is more realistic and realistic.

Next, the operation of the wide vision audio equalizer level display device according to the present invention will be described.

First, when the screen setting of the standard mode 52 is inputted from the function setting unit 30, the control unit 38 displays a signal on the screen that detects the characteristic of the voice signal from the equalizer analyzer 34. In order to control the OSD, the OSD processing unit 42 reads data from the OSD memory 40 so that OSD processing corresponding to the detected signal is performed. .

In order to display the signal applied from the OSD processing section 42 at an appropriate position on the screen, the positioning unit 44 receives the synchronization signal detected by the image IF module in the synchronization detecting section 36 and controls the control unit ( 38) by adjusting the synchronization signal of the OSD processing signal so that the OSD processed signal is displayed on the screen in a blanked portion except for the portion in which the standard mode screen is reproduced or the portion in which the sub picture processing is performed. Specify an appropriate location.

The signal applied to display the equalizer level of the voice at the position designated by the positioning unit 44 is supplied to the image processing unit 16, and the image processing unit 16 receives the signal applied from the positioning unit 44. The image processed signal is output to the screen, and the image processed signal is amplified by the image signal output unit 18 and then displayed on the CRT 20.

Therefore, the equalizer level of the processed voice is displayed in the blanked area without reproducing when the standard mode of 4: 3 aspect ratio is specified in the enlarged mode of 16: 9 aspect ratio, and the PIP mode is set. Equalizer OSD graphic data appears in an area where playback of sub-pictures is not performed.
