Passed to the O processor 18 or was composed of change-over switch (SW3) to be output as the audio interface unit game (G.A) mode.

Referring to the operation, effects of the present invention configured as described above in detail.

When selecting one of the external antennas, video games, and external audio / video inputs as shown in FIG. 2 on the keyboard 14 of VSI, the main microcomputer 12 recognizes the mode. The control unit CON1 (CON2) and CON3 corresponding to the mode are output to the selector 11, and the control unit CON4 and CON5 are output to the interface unit 22. The interface unit 22 The switch SW1-SW11 used in the and selector 11 is an analog switch. When high is input to the control terminal of SW1-7, the switch is connected to the "A" or "a" terminal. It is connected to B "or" B "terminal. It is open when high is input to control terminal of SW8-12 and short when low is input.

Here, the control signal CON1 is a high frequency / game signal, CON2 is a line tuner (LINE / TUN) control signal, and CON3 is a control signal that outputs "H" in normal mode and "H" in normal mode. , CON4 is a control signal for selecting normal video or game video from the LCD interface, CON5 is a control signal for notifying the game mode by opening the switch SW10 (SW11) for a predetermined time (T) when the game video is selected. .

As shown in FIG. 4, the start signal CON6 (CON7) is input from the main microcomputer 12 to the character generator 22a and the melody IC 22b, and the start signal is also input to the game machine 21. do.

When the user selects the video game mode through the VR keyboard 14 in this image, the control signal CON1 (RF / GAME), which is a control signal as shown in FIG. 2 from the main microcomputer 12 to the selection unit 11, Since CON2 (LINE / TUN) and CON3 (H) are output, the first-third switch SW1-3 is connected to the A terminal, and the eighth and ninth switches SW8 and SW9 are opened.

Accordingly, the game video signal selected by the first switch SW1 is signal-processed by the tuner / intermediate frequency processor 11-1, and the processed signal is first buffer 11-2 and second switch SW2. Input into the game video mode (GV) of the interface unit 22 through the second buffer 11-3 and outputs to the game audio mode (GA) of the interface unit 22 through the third switch (SW3). do.

In addition, since the interface portion 22 outputs CON4 (NOR / GAME) as shown in FIG. 4, the movable terminal C of the fourth and fifth switches SW4 and SW5 is connected to the A terminal, Outputs (H) to open the tenth and eleventh switches SW10 and SW11 for a predetermined time T to inform the game mode.

That is, referring to FIG. 4, the game video and audio signals GV and GA received from the selector 11 are switched through the fourth and fifth switches SW4 and SW5 of the interface unit 22. SW11), wherein the start control signal CON5 from the main microcomputer 12 is input high only for a predetermined time T, so that the tenth and eleventh switches SW10 and SW11 remain open only for the period of T. Therefore, the game video and audio signals GV and GA cannot be output to the LCD 10 during T, and the movable terminal c of the sixth and seventh switches SW6 and SW7 is the first fixed terminal A during the T period. The output of the character generator 22a is output to the video / chroma processing unit 10-2, and the output of the melody IC 22b is output to the audio AMP 10-3. The video game mode is notified through the speaker 10-5.

When the T period has elapsed, the start control signal CON5 outputs "low" to short the tenth and eleventh switches SW10 and SW11, and the sixth and seventh switches SW6 and SW7. The video and audio signals GV and GA are output to the video / chroma processing unit 10-2 and the audio AMP 10-3 by connecting between BCs.

In FIG. 5, since the first control signal CON5 is connected from the main microcom 12 to the twelfth switch SW12, the twelfth switch SW12 is opened during T and is shorted when T passes and Vcc is applied. The machine 21 is operated.

When the game machine 21 operates, when a signal is input from the game key 21-1 of the game machine to the video game IC 21-2, video and audio signals are output from the output of the video game IC 21-2.

This high-frequency output is input as a game machine signal to the first fixed terminal A of the first switch SW1 as shown in FIG. 2, and the tuner / middle is selected by selecting the channels CH3 and 4 on the VLC keyboard 14. The image and audio processed by the frequency processor 11-1 are buffered through the first and second buffers 11-2 and 11-3, respectively, and then the image is the second switch SW2 and the audio is the third switch. In this case, the eighth and ninth switches SW8 and SW9 are open, so the outputs of the second and third switches SW2 and SW3 are A of the fourth and fifth switches SW4 and SW5 of the liquid crystal display. After the T period has passed through the terminal, the CON5 control signal goes low, and the tenth and eleventh switches SW10 and 11 are shorted, and the movable terminal C of the sixth and seventh switches SW6 and SW7 is the B terminal. The video and audio of the game are input to the video / chroma processing unit 10-2 and the audio amplifier 10-3 of FIG. 3 to drive the LCD panel 10-4 and the speaker 10-5.

In addition, when the external antenna mode is selected, the CON1 control signal, which is a low signal, is input to the first switch SW1 in FIG. 2 so that the movable terminal C is connected to the B terminal so that the tuner / frequency processing unit 11-1 and The video and audio signals through the buffers 11-2 and 11-3 are input to the second and third switches SW2 and SW3, respectively, and the high signal, which is the CON2 control signal, is the second and third switches SW2 and SW3. ), The movable terminal C is connected to the A terminal, and is input to the second and third switches SW2 and SW3 as the row of the CON3 control signal is shorted to the eighth and ninth switches SW8 and SW9. The video and audio signals are FM-modulated by the video processing unit 17 and the audio processing unit 18 of FIG. 1 via the switches SW8 and 9, respectively, and the audio is amplified to be recordable.

Meanwhile, one of the outputs of the selector 11, that is, the outputs of the eighth and ninth switches SW8 and SW9, is output to the external video and the external audio output, and is inputted to the high frequency modulator 20 so as to be viewed by the TV. It is modulated into a TV signal so that it can be viewed as TV by channels 3 and 4 (CH3 and CH4).

In addition, the video and audio signals are input to the B terminals of the fourth and fifth switches SW4 and 5 since they are inputted to the interface unit 22. In the external antenna mode, the CON4 control signal is turned low so that the fourth and fifth switches SW4, It is input to the tenth and eleventh switches SW10 and 11 through 5). On the other hand, in this mode, the CON5 control signal is always outputted low, so the 10th and 11th switches SW10 and 11 are shorted, and the 6th and 7th switches SW6 and 7 are connected to the B terminal. The video signal is input to the video / chroma processing unit 10-2 through the 10, 11, 6, 7 switches SW10, 11, 6, and 7, and the audio signal is input to the amplifier 10-3.

Finally, when the external audio / video mode is selected, the CON1 and 2 control signals are output low, and the movable terminal C of the second and third switches SW2 and 3 is connected to the B terminal, and the external video and audio signals are connected to the second terminal. The third and second switches SW2 and 3 are input to the eighth and ninth switches SW8 and 9, and other operations are performed as in the external antenna mode.

As described in detail above, the present invention is to realize V-LCDs, LCDs, and game machines in one system, and V-RTs in the ultra-lightweight trend become easier to carry, so that users can watch video games and video tapes while watching LCD screens outdoors. To see the effect.
