In particular, the PC system for implementing a multimedia function, as well as having a variety of functions, such as audio, video, TV, game consoles, communication devices, etc., and must be provided with hardware so as to perform the provided functions without difficulty.

In other words, the CPU used in the PC system to support signals generated from the PC system supporting various functions is required to have a high data processing capability and a high speed. In addition, a monitor used in a PC system having a multimedia function includes not only a video signal processing but also a speaker for processing an audio signal to process various signals.

More specifically, the monitor for supporting the multimedia function of the PC system will be described with reference to the accompanying drawings.

As shown in FIG. 1, the PC system is largely composed of a PC main body 100 and a monitor 200 that processes video signals R, G, and B generated by the PC main body 100. In other words, if the user selects the application selected by the user is executed by the CPU 110 of the PC main body 100. The data generated by being executed by the CPU 110 outputs the video signals R, G, and B and the audio signal through the video card 120 and the audio card 130.

Among them, the video signals R, G, and B that are processed and output from the video card 120 are sufficiently amplified by the video preamplifier 230 in the monitor 200 and then sufficiently through the video output amplifier 230. Amplified and displayed on the CRT. The video synchronization signal 120 outputs the horizontal synchronizing signal H-SYNC and the vertical synchronizing signal V-SYNC for synchronizing the video signals R, G, and B displayed on the CRT.

The horizontal synchronizing signal H-SYNC and the vertical synchronizing signal V-SYNC are output from the microcomputer 210 in the monitor 200 to determine the polarity or frequency, and output the horizontal and vertical output signals according to the result. The horizontal and vertical output signals are processed through the deflection circuit 220 to generate horizontal and vertical sawtooth currents in the deflection coil DY mounted on the neck of the CRT. The video signals R, G, and B applied to the CRT by the horizontal and vertical sawtooth currents are determined and displayed with the horizontal and vertical scanning periods determined.

In addition, if the audio data is included in the application application processed by the CPU 110, the audio data is received from the audio card 130 and processed. The audio signal processed by the audio card 130 is amplified by the audio preamplifier 250 and the audio output amplifier 260 and output through the speaker SP.

In order to process data generated in the main body of a PC system having a multimedia function as described above, the conventional monitor 200 includes a function of amplifying and outputting an audio signal in a function of simply processing a video signal. . In addition, in a multimedia PC system in which a communication function is added, there is a trend to add a microphone function to a monitor to enable voice communication with other users.

As such, the monitor used in the conventional multimedia PC system can use only one monitor to connect data generated from only one PC main body in its function, or simply by using a microphone for another user. There is a problem that is limited to implementing the function of voice communication with.

Therefore, in order to solve the above problems, a signal splitter can be used to distribute a signal generated from a single PC main body without loss and output to at least one monitor, or a monitor having a multiple function. In the case that the microphone (Micro phone) is equipped with this purpose to implement the interphone (Interphone) function.

In order to achieve the above object, the present invention provides a PC main body that generates a signal source, a signal divider that receives and distributes a signal generated from the PC main body, and at least receives a signal distributed from the signal divider. Characterized in that it consists of a monitor unit consisting of one monitor.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

2 is a state diagram of a multiple monitor of a PC system using signal distribution according to the present invention. As shown, from the PC main body 10 for generating a signal source, a signal distributor 20 for receiving and distributing a signal generated from the PC main body 10, and from the signal distributor 20. It consists of a monitor unit 30 consisting of at least one monitor receiving the distributed signal.

During this configuration, the monitor unit 30 may control the first monitor 30-1, the second monitor 30-2,... According to the pan out capability distributed by the signal distributor 20. , N-th monitor 30-n.

In addition, as shown in FIG. 3, the signal splitter 20 receives the signal generated from the PC main body 10, processes the signal, and distributes the signal to the signal processor 21. It is composed of an output port unit 22 configured as at least one output port to be received and transmitted to the monitor unit 30.

The port section 22 includes a first output port 22-1, a second output port 22-2,... According to a fan out of the signal processor 21. And an nth output port 22-n.

As shown in FIG. 4, the signal processor 21 receives a signal generated from the PC main body 10 and blocks 21a for distinguishing between a video signal and a monitor audio signal, and the video signal or monitor audio. A video signal block 21b for processing the video signal divided in the block 21a for discriminating whether it is a signal, and a block 21c for transmitting the video signal processed from the video signal block 21b to each monitor. And a monitor audio signal block 21d for processing the monitor audio signal separated in the block 21a for discriminating whether it is the video signal or the monitor audio signal, and the audio signal processed in the monitor audio signal block 21d. A block 21e is transmitted to the monitors other than the signal source.

Looking at the present invention having such a configuration in more detail as follows.

When the user inputs a command for selecting an application according to a desired task to the PC main body 10, the application is executed by the CPU 11 to generate an image or audio signal.

The generated video or audio signal is transmitted to the signal distributor 20. The signal distributor 20 receiving the signal distributes the transmitted signal through the signal processor 21 according to the pan out processing capability. At this time, of course, the loss of the signal to be distributed is minimized.

More specifically, it is generated by the CPU 11 of the PC main body 10 to distinguish the transmission signal from the video signal or the monitor audio signal by the block 21a. When the signal is divided, the video signal is corrected in the block 21b. When the signal is corrected by the block 21b, the block 21c receiving the signal is distributed with a minimum loss.

In addition, the monitor audio signal classified by the block 21a is corrected by the block 21d. The corrected monitor audio signal is distributed by minimizing loss by block 21e like the video signal.

The video signal and the monitor audio signal distributed by the block 21c and the block 21e include the first output port 22-1, the second output port 22-2, which constitute the output port unit 22, … , The first monitor 30-1, the second monitor 30-2 of the monitor unit 30 is applied to the n-th output port 22-n. Is transmitted to the nth monitor 30-n.

At this time, if the monitor audio signal distributed by the block 21e is the monitor audio signal generated by the PC main body 10, the first output port 22-1 and the second output port of the output port section 22 (22-2),... , The first monitor 30-1, the second monitor 30-2 of the monitor unit 30 is applied to the n-th output port 22-n. Is transmitted to the nth monitor 30-n.

However, if the monitor audio signal input through the microphone (not shown) attached to the monitor, it is output to the remaining monitors except for the monitor. For example, if it is a monitor audio signal input from a microphone (not shown) mounted on the first monitor 30-1 of the monitor unit 30, it is processed by the signal processor 21 to process the first monitor 30-. Second monitor 30-2 except 1),... The output is sent to the nth monitor 30-n.

Therefore, the signal generated by one PC main body 10 can be distributed by the signal distributor 20 to be transmitted and output to the plurality of monitors 30. As a result, when a user runs a game that can be played by two or more people at the same time, the user is provided with the convenience of viewing each monitor and playing the game more conveniently.

In addition, after performing an image on one PC main body 10 during an exhibition or the like using an image, a plurality of monitors may be output to the configured monitor unit 30 through the signal distributor 20 for display output.

As described above, another use embodiment using the signal splitter 20 is described with reference to FIG. 4.

As shown in FIG. 4, the monitor unit 30 capable of inputting / outputting an audio signal and the audio signal generated by any monitor configured in the monitor unit 30 are controlled to be transmitted to the remaining monitors except the monitor generating the audio signal. It consists of a signal processor 21.

A method of controlling such a configuration will be described with reference to FIGS. 5 to 6 as follows.

As shown in FIG. 5, an audio function mounted on an arbitrary monitor of the monitor unit 30 in a normal work state in a general work state desired by the user using the monitor and in the start step S11. If the audio function selection key 1 is not pressed in step S12 for checking whether the selection key 1 is pressed or in step S12 for checking whether the audio function selection key 1 is pressed, the audio function is dismissed. When the audio function selection key 1 is pressed in the step S13 of disabling and in the step S12 of checking whether the audio function selection key 1 is pressed, the step of enabling the audio function ( In step S14, in step S14 of enabling the audio function, step S15 of receiving audio data, which is an audio signal generated when the audio function is enabled, in step S15 of receiving the audio data. )on In step S16 of transmitting the received audio data to each output port; and in step S16 of transmitting the audio data, when the audio data is transmitted to each output port, the audio function selection key 1 is completed. It consists of step S17 which returns to step S12 which confirms that is pressed.

As described above, an intercom function for transmitting audio data, which is an audio signal generated from one monitor, to another monitor is described in more detail.

In the place where the monitor unit 30 composed of a plurality of monitors is installed, the user executes a general operation using the monitor (S11). In this state, it is checked whether or not the audio selection function key 1 mounted on the front lower end of any monitor (shown in FIG. 6) in the monitor unit 30 is selected. This confirmation is of course confirmed by the signal processor 21.

If the audio selection function key 1 is not selected, the audio is disabled (S13). On the contrary, when the audio selection function key 1 is selected, the microphone 2 mounted on the front upper side of the monitor (shown in FIG. 6) is enabled (S14).

When the microphone 2 is enabled, the user inputs his / her desired audio data using the microphone 2. Audio data input through the microphone 2 is received by the signal processor 21 (S15). The received audio data is processed by the signal processor 21 to transmit audio data to each port (S16).

As audio data is transmitted to each port, an audio signal is transmitted to the monitors other than the monitor on which the audio data is generated and output through the speakers 3 mounted on the left and right sides of the monitor (shown in FIG. 6).

Therefore, by processing the audio data generated from one monitor using the signal processor 21 and transmitting to another monitor, it is possible to provide an interphone function that can be used in a variety of monitors.

As described above, the present invention outputs a signal generated from one PC main body to a plurality of monitors using a signal splitter, so that a game or image display in which a large number of people participate can be performed more effectively. Implementing the interphone function using the attached microphone and speaker has an effect of using the monitor more efficiently.
