Abstract

The present invention provides a call information storage and display device using a TV that stores telephone call history in a TV memory and can be checked when necessary. When the TV's micom is connected to the phone and the phone is picked up, the TV is switched to the phone mode, and the call history is stored in the TV's memory in response to the key input and the call connection state of the phone. The screen is configured to be displayed.

According to the present invention, since the telephone usage history can be easily known through the TV, various disputes related to the telephone usage can be prevented.

The present invention relates to a call information storage and display apparatus which can store the usage history of a telephone using a television and can later review the usage history.

In the information age, the use of telephone lines is rapidly increasing, and the use of telephone fees is increasing day by day. These fees are often caused by miscalculations by the telephone company, but they are often caused by the mistake of not knowing that another person used a high-priced phone. For example, when one of the family members or one of the visitors makes international calls or makes various service calls, the telephone charges increase considerably, but the parties who need to pay the telephone bills may not know the details of the usage. In this case, the subscribers are often faced with an alarm after knowing that the telephone charges have been imposed only after they go to the telephone office to protest and check the telephone usage history. In addition, although it is not an excessive amount of money to go to the telephone office to protest, it is often felt that the phone bill is overcharged, and in this case, the desire to check the telephone usage history often occurs.

The present invention was developed in view of the above circumstances, and has a facility for connecting a telephone to a TV and storing the telephone usage history on the TV, so that the telephone usage history can be stored in a weekly or monthly unit and called when necessary. An object of the present invention is to provide a call information storage and display apparatus using a TV.

In order to achieve the above object, in the present invention, a microcomputer is connected to a telephone and senses picking up the handset to switch the TV to the telephone mode, and determines the time when the user starts and ends the call, and the user initiates the telephone call. A microcomputer that determines the time to be used and the time to end, a memory for storing telephone usage history when the user terminates the telephone call, and the usage history stored in the memory when the user wants to check the telephone usage history. And an OSD control unit for displaying on-screen images.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 shows a simplified block diagram of an apparatus according to the invention. In the figure, 1 represents a normal telephone circuit, and 2 represents a microcomputer which controls to switch the television to the telephone mode and store and display the usage history of the telephone when receiving the off-hook signal from the telephone circuit 1. 3 is a timer that provides a current time, 4 is a memory for storing telephone usage history, and 5 is an OSD for controlling on-screen display of usage history when checking the usage history stored in the memory 4. The control unit 6 is a cathode ray tube (CRT) for displaying the usage history on-screen. The microcomputer, timer, memory and OSD control unit may use existing television circuits.

When the user raises the handset (off-hook) to make a telephone call, an off-hook signal is applied to the microcomputer 2 of the television, and the microcomputer 2 activates the telephone mode of the television. In the telephone mode, when the television recognizes a telephone hook and button operation and presses a numeric button or a memory shortcut button to select a telephone number, the date and number of the telephone are temporarily stored in the temporary storage place (register) of the television. When the other party picks up the telephone receiver by the telephone call, the normal call is started. At this time, the microcomputer calls the current time from the timer and stores it in the temporary memory as a call start time.

When the user finishes the telephone call, the microcomputer 2 calls the current time in the timer 3 and stores it in the temporary storage place as the end time of the call, calculates the total talk time, and then stores the call stored in the temporary storage place. The information is called up and stored in memory 4 for permanent storage. Therefore, the memory 4 stores, for example, a telephone usage date, a telephone number, a telephone call start time, a telephone call termination time, and a total telephone time in the form of a table so as to clearly know the telephone usage history as shown in FIG.

When checking the telephone usage history, it can be checked in units of daily, weekly or monthly. When the specific key prepared for the telephone usage history is pressed by the remote control transmitter and the desired period for examination is specified, the microcomputer 2 calls the stored contents of the specified period in the memory 4. The called information is displayed on-screen on the cathode ray tube 6 through the OSD control unit 5, and the user can easily know the telephone usage history for a certain period of time through the television screen.

As described above, according to the present invention, since the telephone usage history can be all memorized by the television, when the charge of the telephone bill is considered excessive, it can be checked by calling the usage history on the television at any time. Also, if you specify more items of contents stored in memory, telephone usage information can be used for various useful purposes.
