Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 4.

First, when a television broadcast signal of a predetermined channel tuned through a tuner (not shown) in step 60 performs an intermediate frequency amplification operation and an image / audio detection operation, the image signal processing unit 2 detects the detected image intermediate frequency signal. The multi-stage signal amplification and band amplification are performed, and the image output unit 4 synthesizes and outputs the R / G / B color signal through luminance adjustment for the luminance signal and color demodulation of the color signal. The R / G / B color signal processed by the image signal is amplified and driven to enable image reproduction through the CRT. In addition, the voice signal processor 6 outputs the voice signal through the sound quality control and volume control process for the voice signal detected, and the voice output unit 8 amplifies the speaker by power-amplifying the voice signal processed. Audio can be output through

In that state, the process proceeds to step 61 where the main controller 24 determines whether or not fax information has been received from the other party's side via the fax modem 10.

As a result of the determination in step 61, if the main controller 24 determines that predetermined fax information is being received through the fax modem 10, the control proceeds to step 62 to control the key operation of the function setting unit 22. It is determined whether or not a function command for outputting the received fax information in the form of voice is input.

As a result of the determination in step 62, if the main controller 24 determines that the function setting section 22 is not performing a key operation for executing the voice output function for the fax information, the control proceeds to step 63. By the control communication with the fax control section 26, character conversion processing by MMR coding for the fax information received by the fax signal converting section 12 is performed.

Accordingly, the MMR memory 32 of the fax signal converting unit 12 stores and processes the fax information data received from the other party received through the data receiving unit 30, and the MMR controller 36 stores the fax control unit ( Under the control of 26), the character data processing unit 34 performs MMR coding processing on the fax information data based on the MMR control program of the MMR control memory 38 to convert the fax information data into character data. Fax character data converted through the processing unit 34 is output through the output buffer 40 is applied to the fax output processing side via the fax output switching unit 14 to be received and output through a predetermined fax paper. .

However, if it is determined that the function setting unit 22 is performing a key operation for voice output of the received fax information, the control proceeds to step 64 and the fax output switching unit 14 is determined. Switching control so that the fax character data of the fax information converted by the MMR coded by the fax signal conversion unit 12 can be supplied to the character recognition processing unit 16, so that the character for the character recognition processing unit 16 can be supplied. The recognition operation and the voice conversion processing operation of the voice conversion processing unit 18 are controlled.

Accordingly, the character data memory 44 of the character recognition processor 16 stores the fax character data according to the fax information received through the character receiver 42, and the character recognition controller 48 stores the recognition control memory ( According to the control algorithm of the control program of 50), the character recognition unit 46 controls to convert the recognition character into code data by character recognition for the fax character data.

Then, the speech synthesis section 54 of the speech conversion processing section 18 receives the code data of the character recognition processed recognition character and reads it from the speech memory 52 under the control of the speech synthesis control section 56. A speech synthesis operation is performed on the speech data corresponding to the code data, and the speech decoder 58 decodes and analog converts the speech synthesized speech synthesis data and outputs it as a speech synthesis signal.

As a result, in step 65, the main control unit 24 switches the voice mode switching unit 20 so that the voice synthesis signal according to the fax information voice-converted by the voice conversion processing unit 18 is converted into a voice signal processing unit ( 6) is supplied to the voice signal processing result as a result of the voice output from the speaker through the power amplification of the voice output unit (8).

On the other hand, in step 66, the main controller 24 determines whether reception of the fax information in the fax modem 10 is terminated.

As a result of the determination in step 66, if it is determined that the reception of the fax information is finished, the main controller 24 proceeds to step 67 to perform the processing operations of the text recognition processor 16 and the voice conversion processor 18. Initializing and switching control of the voice mode switching unit 20 allows the voice signal of the television broadcast to be applied to the voice signal processing unit 6 so as to process the voice signal and output the normal voice.

According to the present invention made as described above, when predetermined fax information is received from a television having a transmission and reception output function of a fax, the received fax information is converted into a voice signal so as to be output through a speaker. In addition, the time required to print out the fax paper and the printing of the fax paper for the confirmation of the fax content become unnecessary, thereby facilitating the confirmation of the fax content more easily and bringing the savings of the fax paper. It has the advantage that it is.
