Television displaying the caller's phone number {Television of displaying caller ID}

The present invention relates to a method for displaying caller information, and more particularly, to a television for displaying a caller's telephone number so that a user can easily recognize the caller's telephone number by additionally configuring a circuit for displaying the caller's telephone number on a general TV screen. will be.

In general, when a call comes from a home, a caller tracking function is applied to a telephone company in advance to know the caller's information, or in special cases, the caller can be tracked in cooperation with the police department.

On the other hand, while a recent telecommunication company has decided to implement a caller information service (Caller ID) as part of an additional service, a general telephone user can know the caller's telephone number through the display device of the telephone.

However, even if the caller information service is implemented, if the existing phone does not have a display function, there is a problem in that a new phone or display device having a separate display device must be purchased separately.

Even if you use a phone with a display function on an existing phone, the display device is small, so if you are away from the phone, you must move to where the hand-held display device is located. As it is understood, inconvenience follows.

In order to solve the various problems as described above, a message input circuit using a television has already been announced in the prior art (notice number: 1997-0010387).

Referring to FIG. 1, the invention disclosed in the related art will be described in detail. The interface circuit 1 is connected to the telephone of the called party and performs a switching operation, and the code data of the telephone number received by the interface circuit 1 is detected. A control circuit 3 for comparing the detection circuit 2 with the ring data output from the detection circuit 2 and the reference ring data and interfering with the corresponding operation; and the control data output from the control circuit 3. System controller (4) operated by the system to control the overall operation of the system, a storage circuit (5) storing memory voice data, an outgoing telephone number, and current time data, and when the called party is detected to be absent Announcement circuit 6 for reading out and outputting the corresponding message data and predetermined number data inputted from the caller by the announcement circuit 6 are used. A telephone number recognition circuit 7 for recognizing and supplying code data corresponding thereto, and an OSD output circuit 8 for outputting the telephone number and time data corresponding thereto received by the data selected by the consumer to the OSD device. have.

However, the present invention is that the caller information is displayed only when the caller tries to notify the recipient by directly pressing the phone number of the caller, and also can be known if the caller leaves the caller's phone number by the memory function when the caller is absent. There is no function to determine whether or not a call after checking the caller's telephone number which is the purpose of the invention.

Accordingly, the present invention has been made to eliminate the above inconvenience, to provide a television that makes it easy to know the caller's telephone number through the TV screen by adding a line indicating the caller information to the TV much larger screen than the phone The purpose is.

As a technical means for achieving the above object, the present invention provides a public switched network system in which a service for transmitting a caller's telephone number together at the time of ring signal output to any caller is provided. A call forwarder for receiving a caller's phone number together; A decoding unit converting a caller's telephone number signal received at the called telephone into code data corresponding thereto; The microcomputer is configured to output an OSD signal to a television receiver using a telephone number corresponding to code data output from the decoding unit.

In addition, the microcomputer OSD outputs code data of the caller's telephone number when the television is turned on when the caller's telephone number is received.If the television is turned off when the caller's telephone number is received, the microcomputer turns on the television and then codes the caller's telephone number. It is characterized by an OSD output of data.

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

2 is a block diagram of a television displaying a caller's telephone number in accordance with the present invention.

The apparatus shown in FIG. 2 receives an originating telephone 10 with which an arbitrary caller attempts to make a call, and an originating telephone number which is received together at the time of ring signal output from the arbitrary originating telephone 10 through an exchange 20. Incoming telephone 30, the display unit 31 to display the corresponding display in accordance with the mode according to the user setting, such as the caller's telephone number and the current time to the incoming telephone 30, and the incoming telephone 30 is called A television 40 that displays the calling party's telephone number.

In this case, the display unit 31 may not be present depending on the type of telephone used by the user.

The television 40 has a decoding unit 41 for converting the caller's telephone number signal received by the called telephone 30 into code data corresponding thereto, and receives the caller's telephone number data from the decoding unit 41 and receives the CRT ( 43) and a microcomputer 42 for outputting an OSD (On Screen Display) signal.

At this time, the OSD signal output to the CRT 43 is in the form of 'call from ***-****', and the font size is adjusted according to the user's setting, so if you want large letters, set large and small. If you want letters, you can set them smaller.

The operation of the present invention configured as described above will be described with reference to a flowchart relating to a process of outputting an OSD signal to a television receiver when receiving a caller's telephone number of FIG.

First, when a call is received from an arbitrary caller, a ring signal sounds to the called telephone 30 and information about the caller's telephone number is applied to the caller's telephone number decoding unit 41 of the television 40. At this time, if the phone has a separate display unit 31, information on the telephone number is also displayed on the display unit 31.

On the other hand, when the caller's telephone number is applied to the television 40, the microcomputer 42 checks the caller's telephone number reception state through the step S1 of comparing and determining whether the caller's telephone number has been received and signals the television 40. In order to display, first, it is determined whether the power of the television is turned on (S2).

When the television 40 is in the on state in S2, the OSD signal is immediately output to the CRT 43 (S4), and when the television 40 is in the off state, once the power of the television 40 is turned on ( S3) The OSD signal is output to the CRT 43 (S4).

Therefore, the user can easily know the caller's telephone number because the caller's telephone number is displayed on the television screen even if the user is far from the telephone, and there is no need to see and confirm the small display unit 31 of the telephone.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention described in the claims. Of course, such a change is of course within the scope of the present invention.

As described above, the present invention does not require the purchase of a separate telephone because the telephone displays the outgoing telephone number even if the telephone itself does not have a display portion, and even if the telephone has its own display portion, there is a limit to display the size so that the user can easily recognize it. Since the screen is displayed using a relatively large screen, the caller's phone number can be easily checked, thereby maximizing the convenience of use.
