Next, the operation of the present invention made as described above will be described in detail with reference to the accompanying drawings.

First, a video signal of a predetermined broadcast channel tuned by a tuner (not shown) is processed by the video signal processing unit 12 to be reproduced on a CRT screen so that a television broadcast program of the corresponding broadcast channel is reproduced. When the setting key 24A of the function setting unit 24 is key-operated to transmit request information for an additional service related to a predetermined broadcast program, the main control unit 26 controls the OSD of the OSD signal processing unit 16. The control unit 58 controls the OSD synthesizer 46 to read OSD pattern data from the OSD pattern memory 48 according to the additional service, and also OSD character data from the OSD character memory 50. The data is processed by synthesizing the data, and the OSD display information data of the request information according to the data synthesis processing of the supplementary service is analog-converted by the signal conversion unit 62 to perform the video signal processing unit 12 as a medium. The screen is displayed as a plurality of function icons 64 on the CRT screen (see Fig. 4A).

In this state, the selection key 24C and the designation key 24D of the function setting section 24 are key operated, and among the request information for the additional service displayed as a plurality of function icons 64 on the CRT screen. When predetermined request information such as, for example, sports game information is specified, the main controller 26 reads the fax record document information data of the request information corresponding to the designated function icon 64 from the fax information memory 4. In accordance with the present invention, the signal conversion unit 6 converts the fax record document information data of the request information, for example, the sports game information, which is loaded and output from the fax information memory 4 into a fax information by converting the MMR code into fax information. Through (2) it is transmitted to the television station.

Then, when the fax information in response to the request information for the sports competition information is received from the television broadcasting station via the fax modem 2, the fax signal converting section 8 controls the fax control section 29. The received fax information is converted into fax text data by MMR decoding processing, and the fax text data through the fax output switching unit 10 is applied to the OSD signal processor 16.

At this time, the fax character memory 54 of the OSD signal processor 16 stores and processes the fax character data received through the fax character receiver 52, and the OSD controller 58 controls the main controller 26. As the OSD character data corresponding to the fax character data is read out from the OSD character memory 50 based on the control program of the program memory 60, the OSD character unit 56 converts the fax character data into the OSD character. The data is converted into data and analog-converted through the signal converter 62 and applied to the image signal processor 12.

Therefore, on the CRT screen, as shown in FIG. 4B, the fax information for the requested sports game information can be displayed as OSD display information.

In addition, the present invention having the above-described embodiment, when the output selection key 24B of the function setting section 24 is a key operation, when the output selection through the predetermined fax paper is made, the fax output switching unit 10 is turned off. By switching switching, the fax information about the sports game information can be output on the fax paper by the TPH 20 via the fax thrust processing unit 18.

According to the present invention made as described above, as a request information relating to a predetermined television broadcasting program is created on a television with a fax function and transmitted to the television broadcasting station, receiving fax information in response to the request information is received from the television broadcasting station. As it can be displayed on the screen, not only passive reception and reproduction of a television broadcast program, but also active request for additional information and confirmation of desired information are made possible, and thus, there is an advantage of providing convenience to the viewer.
