Abstract

(57) [Abstract] [PROBLEMS] When a signal of a game device is connected and displayed from a video input terminal, it is an object to automatically switch the characteristics of an audio circuit when the game device is selected. SOLUTION: When a game mode selection signal is applied to an audio signal switching circuit 2 and a control signal generating circuit 1, an audio signal of a game device is selected and applied to an audio characteristic control circuit 3 via the audio signal switching circuit 2, At the same time, a voice control signal is applied to the voice control circuit 3 to obtain an output voice signal having a voice characteristic set by the user.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio signal control circuit for a television receiver.

[0002]

2. Description of the Related Art Conventionally, when a game machine is connected to a television to display video and audio, for example, Japanese Patent Laid-Open No. 4-2372.
Japanese Laid-Open Patent Publication No. 74 proposes a configuration in which the antenna or the video input terminal is automatically switched to the terminal to which the game device is connected when the game device is turned on.

Further, Japanese Patent Laid-Open No. 145847/1993 proposes a device for automatically preferentially selecting one video device (game device) from a plurality of video devices.

[0004]

When a signal from a game device is connected to a video input terminal for display, when the terminal to which the game device is connected is selected so that it will not be tedious for a longer time than before, the screen brightness will be automatically adjusted. There are things that reduce the quality.

However, the voice circuit is not particularly controlled, and there is the inconvenience that the user controls it to his or her own preference each time.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and is to automatically switch the characteristics of an audio circuit when a game machine is selected.

In order to achieve the above object, the present invention is to change the characteristics of the audio signal in the audio characteristic control circuit to the state set by the user in the signal for selecting the game machine.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is such that a screen image is switched to a signal of a video input terminal connected to a game machine at the same time by a signal of a main body switch of a television receiver or a remote controller. By switching the characteristics of the audio circuit, there is the effect that the complexity of operating the audio characteristics each time a game device is selected is eliminated.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. (Embodiment 1) In the television receiver shown in FIG. 1, 1 is a control signal generation circuit of an audio circuit, 2 is an audio signal switching circuit, 3 is an audio characteristic control circuit, 4 is an audio amplification circuit,
5 is a speaker, 2 is an audio signal of a game device connected to an input terminal a, and b is an audio signal from a tuner. When the game mode selection signal is applied to 2, the game voice signal from a is selected.

When the game mode selection signal is applied to 1, the audio characteristic control signals are applied to 1 to 3 to control the audio characteristics. As a characteristic, emphasize the low range and high range of the voice,
Alternatively, reverberation is added to the input signal, or both are performed simultaneously.

[0011]

According to the present invention, the voice characteristics suitable for the game can be obtained only by the user switching to the game mode, which is more preferable.
