Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 6.

First, in step 70, when the mode key 16A of the function setting unit 16 is operated to set the fax selection mode, the main control unit 20 executes the corresponding fax selection mode, and executes the OSD signal processing unit 28. By controlling the function, the caller's telephone number inputted by the repetitive key operation of the 10-key 16B and the setting key 16C of the function setting unit 16 is displayed on the OSD. It is stored in the memory 18.

At this time, the OSD character decoder 46 of the OSD signal processor 28 is synchronized with the horizontal / vertical synchronization signal HS / VS separated from the synchronization separator 26 and under the control of the OSD controller 56. On the basis of the OSD character data read from the character memory 48, a decoding operation for generating the OSD display information according to the registration number inputted by the function setting unit 16 is performed, and the signal conversion unit 60 performs the decoding operation. As the OSD display data decoded through the OSD character decoder 46 is analog-converted and applied to the image signal processing unit 2, a plurality of registration numbers can be displayed on the CRT screen as shown in FIG. Be sure to

In that state, the process proceeds to step 71 where the video signal processing unit 2 and the audio signal processing unit 6 are tuned from a tuner (not shown), and the video / audio signal of the video / audio signal of the television broadcast subjected to the intermediate frequency conversion and amplification processing. The audio signal processing is performed to generate R / G / B color signals and audio signals, respectively, and the video / audio output units 4 and 8 respectively process the R / G / B color signals and audio signals processed by the video / audio signals. The signal is amplified and driven to reproduce video / audio through the CRT and the speaker, respectively.

At this time, in step 72, the main controller 20 determines whether or not predetermined fax information from the counterpart transmission side is received through the fax modem 10.

As a result of the determination in step 72, if it is determined that predetermined fax information is being received through the fax modem 10, the control proceeds to step 73 and the main controller 20 transmits to the control communication with the fax controller 22. By doing so, the fax signal converting unit 12 performs MMR coding on the fax information received through the fax modem 10 to convert the text into fax character data.

On the other hand, the character recognition processing unit 14 performs character recognition on the information data of the caller's telephone number according to the caller information data 42 (see FIG. 3) among the fax character data MMR coded through the fax signal converting unit 12. Code data according to the recognized character is generated.

Subsequently, the process proceeds to step 74 where the main controller 20 receives the code data of the recognized character through the character recognition of the caller's telephone number applied from the character recognition processor 14 and registers the data stored in the data memory 18. As a result of the comparison with the number, it is determined whether the outgoing telephone number of the received fax information is a registered telephone number.

As a result of the determination in step 74, if it is determined that the calling party's telephone number of the received fax information does not correspond to the registration number stored in the data memory 18, the control proceeds to step 75 and the main controller 20 sends the fax. By switching the output switching unit 24 to the fax output processing side, control communication with the fax control unit 22 is performed so that the fax character data from the fax signal conversion unit 12 is received and output in a normal output manner through a predetermined fax paper. Do it.

However, as a result of the determination of step 74, the main controller 20 compares the code data according to the character recognition of the caller's telephone number from the character recognition processor 14 with the registration number from the data memory 18. If it is determined that the telephone number of the received fax information is a pre-registered number, the control proceeds to step 76 in which the switching control of the fax output switching unit 24 is performed to the fax information from the fax signal conversion unit 12. The facsimile text data is supplied to the OSD signal processor 28 to be converted into OSD display text.

At this time, the OSD control unit 56 of the OSD signal processing unit 24 is received through the fax character receiving unit 50 based on the control program from the program memory 58 under the control of the main control unit 20 to receive the fax character. By reading the OSD character data of the OSD character memory 48 in response to the fax character data stored in the memory 52, the OSD character is converted into the OSD display characters through the OSD conversion unit 54 and outputted. The unit 60 converts the OSD display data according to the OSD information converted by the OSD through the OSD converter 54 and outputs the analog signal to the image signal processor 2.

In that state, the flow advances to step 77 where the main controller 20 determines whether the reception state of the fax information is terminated through the fax modem 10.

As a result of the determination in step 77, if it is determined that reception of the fax information from the fax modem 10 is terminated, the control proceeds to step 78 to initialize the operation of the OSD signal processor 28 and enter the standby state. .

According to the present invention made as described above, if a predetermined caller's telephone number is registered in advance on a television with a fax function, only the fax information of the telephone number corresponding to the registered number is subjected to OSD conversion processing through the CRT screen. By allowing the screen to be displayed, it is possible not only to selectively and easily check the contents of the received fax information, but also to prevent unnecessary output of the fax information, thereby reducing the waste of fax paper. .
