However, if you are calling from outside while watching a satellite broadcast using the set-top box operating as described above, you must go to the phone to check the caller information, or if the other party does not hang up if you do not answer the call. There is a problem that the telephone ringing continues to be a barrier to watching satellite broadcasting.

Therefore, an object of the present invention for solving the conventional problems as described above is provided with a circuit that can decode caller information (CID) in the modem built into the set-top box to the monitor even while watching satellite broadcasts when a call is received from the outside. The present invention provides a method of displaying caller information using a modem of a set-top box to display caller information.

It is another object of the present invention to provide a method of displaying caller information using a modem of a set-top box which compares the received caller information with information stored in the system memory and displays it on the monitor screen only when it is an incoming number or a desired telephone number. have.

It is still another object of the present invention to provide a method of displaying caller information using a modem of a set-top box that transmits a prank call erasure message to a counterpart phone when the received caller information is a desired phone number and displays the same on a monitor screen. have.

In order to achieve the above object, the present invention provides a first step of detecting caller information when a call is received while watching a satellite broadcast, a second step of comparing the detected caller information with information stored in a memory, and If the caller information is in the information stored in the memory to display on the monitor screen to determine whether or not, and if the caller information is not stored in the memory in the second step to transmit the prank call erasure voice And a fifth step of updating the reception list and the recent call log when the user receives the incoming call in the third step, and updating and ending the unreceived list when the call is not answered.

Hereinafter, with reference to the accompanying drawings in detail as follows.

FIG. 2 is a flowchart illustrating a method for displaying caller information using a modem of the set-top box according to the present invention. As shown in FIG. 2, a first step of detecting a ring while watching satellite broadcasts and detecting caller information when detecting a ring are described above. And a second step of comparing the detected caller information with the information stored in the memory, and displaying the caller information on the monitor screen if the caller information is in the information stored in the memory. A fourth step for transmitting the prank call erasing voice if the caller information is not stored in the memory in the third step; and a reception list and a recent call when the user receives the incoming call in the fourth step. The sixth step is to update the record, update the unreceived list and exit if not answered.

When described in detail with respect to the operation and effect of the present invention made of each step as follows.

Today, privacy of individuals is very important.

Therefore, when a user makes a call from outside while watching a broadcast satellite, the caller decides whether to receive a call according to the caller.

The modem portion 107 of the circuit shown in FIG. 1 has a caller ID decoding circuit capable of decoding caller information coming between the first ring and the second ring to the ring circuit and a voice modem for exporting a message. It is added.

The message sent through the voice modem is compressed and stored in the system memory 104.

With this added set-top box, satellite or terrestrial signals over the earth can be received via antennas.

The received analog signal is converted into a digital transport stream in the channel unit 101 of FIG. 1 and transmitted to the demultiplexer unit 102. The signal converting method is based on various demodulators and various decoding methods depending on satellite broadcasting or terrestrial broadcasting. The method is applied.

The signal converted into a digital signal is separated from the transport stream into data including video data, audio data, program guide information, and rating information under the control of the microprocessor 103 in the demultiplexer unit 102.

Among the separated data, the video data is compressed by the OSD processing and video processing unit 106 in the MPEG-2 standard and is converted into the original video data.

The changed data outputs the OSD data input by the user to a high definition (HD) or standard definition (SD) monitor connected to the set-top box.

The audio data of the separated data is decoded by the MPEG-2 or AC-3 decoder by the audio processor 105, and the original audio data is sent to the speaker by adjusting the ring sync to match the time of the video so that the viewer can hear the audio. To help.

At this time, the microprocessor 103 serves to transmit control signals and data to each part so as to facilitate all the above operations.

As described above, the satellite processing processed by the audio processing unit 105 and the OSD processing and video processing unit 106 is viewed.

When a call is received from the outside while watching satellite broadcasts, the modem unit 107 decodes the caller information and transmits it to the microprocessor 103. Here, the caller information includes the call origination time, the calling telephone number, and the caller.

The modem unit 107 is configured as a modem to be uploaded to a service provider through a public switched telephone network (PSTN). The voice function is added to the modem, and the first and second rings are provided in the ring circuit. Add circuit diagrams to decode caller information in between.

The microprocessor 103 receiving the caller information controls the OSD processing and video processing unit 106 to implement and display an OSD menu capable of adjusting the displayed position or size, as shown in FIG. 3.

The system memory 104 stores telephone numbers corresponding to the reception list to be received and the unreceived list not to be received.

The user information displayed in the OSD menu on the screen is compared with the information stored in the system memory 104.

As a result of the comparison, if it is stored as a phone number previously received or stored as a phone number that the user does not want to receive in the system memory 104, the microprocessor 103 may send a message for eradicating a prank call stored in the system memory 104. The modem unit 107 transmits the data to the PSTN.

In this case, the microprocessor 103 performs OSD processing through the OSD processing and video processing unit 106 to display the message to the viewer, indicating that the message for erasing the mischief phone is outputted through the modem unit 107.

The next step is to allow the user to decide whether to receive the call if the received phone number is the first call received or if it is on the receiving list.

In this case, if it is determined that the reception is successful, the microprocessor 103 updates the reception list stored in the system memory 104 to inform that the number is to be received afterwards.

This recent call log is stored in the system memory 104 in a compressed form to use less memory, store a week or a month worth of calls, and a week or month of call records if the user requests The OSD menu is configured to display in the order of call volume.

If the user selects unreceived in the reception decision step, the microprocessor 103 updates the unreceived list and updates the prank call erasing list to transmit the voice to the other party through the voice modem.

Also, the timer is set to disappear from the screen after a certain time without determining reception or non-receipt.

Finally, because the set-top box is always powered on to receive program guide information, when a call is received from the outside while the phone is missed, the microprocessor 103 stores this information in the system memory 104 so that the user can monitor the monitor. When turned on, it is designed to show information at this time.

As described in detail above, the present invention uses a set-top box with a caller information decoding circuit and a voice modem to allow a user to selectively receive a call according to the caller when a call is received from outside while watching a satellite broadcast. If the call is not made, the pre-recorded anti-prank message is sent to the other party through the voice modem so that the prank call can be made. In addition, the set-top box is always on, so it is possible to check the incoming call when not in the office.
