It consists of a microcomputer 101 for controlling each operation of the.

Referring to the operation and effect of the present invention configured as described above are as follows.

First, a user is provided with a recognition name and password from an information provider through another path, and then enters the information provider's telephone number, his or her identification name and password by means of a key input means, in particular, the remote control 113, and the microcomputer. 101 stores in the internal memory and determines whether the communication mode is set.

When the microcomputer 101 presses a specific key, for example, a '#' or '*' key on the remote control 113, and selects a number to which an English letter is assigned, it is determined as input of the corresponding English letter.

In the above, the character input may be made to be input by the VRC provider using a specially designed input equipment.

At this time, when the user sets the communication mode using the remote controller 113 or the key input unit, the microcomputer 101 reads data about the telephone number of the information provider and outputs the data to the video decoder 110 and the video decoder 110. Performs a decoding operation and displays the name and phone number of the information provider on the TV screen.

It may also require the entry of a password.

Accordingly, when the user selects the telephone number to be communicated among the telephone numbers displayed on the TV screen by the remote controller 113 or the key input unit, the microcomputer 101 converts the telephone number of the corresponding information provider into a tone and transmits it to the telephone line. To control the modem 105.

Thereafter, if a response tone for a ring tone is received and the modem 105 is requested to transmit a recognition name from the information provider when the modem 105 is connected on-line with the information provider, then the microcomputer 101 is internal. The microcomputer 101 reads the recognition name stored in the memory and transmits it to the information provider through the modem 105, and the information provider determines that the received recognition name is correct. It reads its password stored in the internal memory and transmits it to the information provider through the modem (105).

Subsequently, when the menu of the service information transmitted from the information provider determined that both the recognition name and the password are correct is received by the modem 105, the horizontal address generator 102 resets the horizontal synchronization signal (H-sync). The vertical address generator 103 reset to the synchronization signal V-sync counts the clocks H-clk and V-clk, respectively, and inputs the horizontal address and the vertical address to the frame memory 104. .

At this time, the frame memory 104 stores the data received by the modem 105 in units of frames in the area designated by the addresses generated by the horizontal address generator 102 and the vertical address generator 103, and performs digital / analog conversion. The output to the unit 106 is made.
