A modem for performing data and voice transmission and reception through a telephone line under the control of an information processing block;

By providing a modem and a speaker for outputting a telephone voice signal by the control.

According to the present invention, when a telephone number is input to a transmitter, the modem dials it, and when a telephone is connected, a relative voice signal is output to a speaker, but when a handset is heard, a call is made through the telephone.

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

1 is an implementation circuit diagram of the present invention, wherein the CPU 100 performs control and data transmission and operation of the entire system according to a control signal of the information processing block 300 by a program stored in a program ROM.

Data processing for peripheral function blocks in the CPU 100 is performed by interrupts, and the function of transferring various interrupts required for system control to the CPU 100 is performed by the modem 200 and the information processing block 300.

The interrupt request is generated by various tasks (TASK) in the modem 200 and the information processing block 300. The task is mainly performed by receiving infrared data from a transmitter, vertical blanking time, internal timer, or television microcomputer. It is generated when the CPU 100 processes the task whenever an interrupt occurs.

The information processing block 300 is a function of generating a control signal necessary for the entire system, a memory 400 constituting the memory means and a control function of the ROM 500, synchronizing with an external video synchronization myth, and superimposing with an external video signal. The pause function, a function of receiving infrared data input from an external transmitter and transmitting the same to the CPU 100, a function of recognizing the interrupt generated by the modem 200 and informing the CPU 100, a graphic and video control function, and graphic data Outputs and executes its own synchronization signal generation function.

The modem 200 demodulates the modulated signal received through the telephone line, detects and corrects an error, stores the data in an internal buffer, generates an interrupt in the CPU 100, and stores the currently received data in the memory means. 100) receives the digital data to be transmitted to the telephone line, modulates it and sends it.

The modem 200 is connected to a telephone line and a telephone, and detects on-hook / off hook detection, telephone key tone detection, and key number of the telephone to the CPU 100, and detects and encodes keytone information input through the telephone line. After that, the data is transferred to the CPU 100.

The speaker 600 outputs a television voice signal or an information service voice signal or outputs a voice signal of the other party during a telephone call.

The transmitter for inputting transmitter data to the information processing block 300 is provided with a dialing key for selecting the telephone dialing mode.

The user presses the dialing key of the transmitter to dial the telephone using the transmitter.

When the dialing key of the transmitter is pressed, the information processing block 300 recognizes the dialing state on the screen and interrupts the modem 200.

When the desired telephone number is input by pressing a numeric key of the transmitter, the information processing block 300 recognizes this and displays the telephone number on the screen, and the modem 200 performs charge dialing.

As a result of dialing in the modem 200, when the other party is in a call, the display shows a call on the screen and stops the telephone dialing operation.

However, when the other party picks up the phone, the modem 200 outputs the voice signal transmitted through the telephone line to the speaker 600 to notify the user by outputting the other party's voice signal to the speaker 600 that the user is connected to the other party. .

The user listens to the voice signal output to the speaker 600 and listens to the telephone. The modem 200 starts at this time the voice signal is made through the telephone and is not output to the speaker 600.

That is, when the other party responds by dialing in the modem 200, the speaker 600 outputs it to the user and recognizes the user. When the user lifts the phone, the call is made through the phone from the moment.

Therefore, it is easy to use because you only listen to the phone when you sit still and make a phone call.

2 is a flow chart of the present invention, which checks whether there is a dialing key input of a transmitter,

Checking the number input of the telephone number and displaying the input number on the screen;

Dialing the input telephone number and checking whether the telephone is connected;

Checking whether the telephone is connected to the speaker with a voice signal when the telephone is connected;

Lifting the phone is carried out by a process for making a telephone call.

Whether the dialing key of the transmitter is pressed is recognized by the CPU 100 via the information processing block 300 (step S1).

If the dialing key of the transmitter is not input, the user exits the luton, and if the dialing key is input, the screen indicates that the dial mode is selected (step S2).

Screen display is performed by receiving the command of the CPU 100 and outputting the screen display R.G.B signal in the information processing block 300.

When the dial mode is displayed on the screen, it is checked whether there is a numeric key input, which is a telephone number, from the transmitter (step S3). If there is a numeric key input, the number is displayed on the screen to confirm the telephone number to the user (step S4). Check if it is completed (step S5).

When the phone number input is complete, send the phone number data to the modem 200 to dial in the modem 200 (step S6)

After dialing, it is checked whether a telephone connection is established (step S7).

If the other party is busy, the phone cannot be connected. Therefore, after the busy display on the screen, the user exits the routine.

However, when the call is connected with the other party (when the other party picks up the phone), by operating the speaker 600 to output the other party's voice signal to the speaker 600 (step S8), the user can know whether the other party has heard the phone. have.

That is, when a specific person answers by making a phone call in the modem 200, the voice signal of the other party is output to the speaker 600 so that the user can easily recognize it.

Check whether the user hears the audio signal output to the speaker 600 and listens to the handset (S9 step).

When the handset is heard, the voice signal output to the speaker 600 is blocked (step S10), and the telephone and the other telephone are connected.

Then, it is checked whether the call is completed (step S12). If the call is not terminated, a telephone call is made to the phone as described above, and if the call is terminated, the routine exits.

In other words, by making a call to the transmitter and having the other party pick up the telephone, the telephone is picked up so that the dialing operation can be easily performed without using a handset in the information television.
