Description

Fax function Receiving status display processing device of television

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fax information receiving status display processing apparatus of a television with a fax function. Fax function that displays the reception status of a plurality of fax information received through the fax modem on the built-in television with the fax function to enable OSD screen display for selective confirmation of predetermined fax information. A reception status display processing apparatus.

As is well known, in a typical television, a predetermined channel is tuned to a video / audio process for a multichannel broadcast RF signal transmitted from a plurality of television stations in the form of over-the-air, so that the video / audio can be reproduced through a CRT and a speaker, respectively. In addition to the video / audio playback function of a television broadcast, video / audio processing from video recording media such as a video tape read out from an external video player such as a video tape recorder is performed. As a result, it is also equipped with an external signal video / audio playback function for playback through each CRT and speaker.

On the other hand, in such a television, in order to diversify functions, when a telephone number is inputted by connecting a telephone line with a public telephone network, a call operation can be made with the other party's receiver and a call received from the other party. The call-in / out function has been developed and adopted. According to the call-in / out function, when a call is received in the state of watching a television or when a call needs to be made with a predetermined receiver, the telephone is not moved to a remotely located location. A telephone number can be input by a button operation by a remote controller for remote control, or a handset operation with the other party can be made through a handset provided at a predetermined portion of the remote controller.

In addition to the above-described function of making and receiving a voice call through a public telephone network, such a television can transmit and receive text and images in a predetermined data format such as MMR format to receive and output through a fax paper. As the fax function is adopted, the fax function provided in the television includes a fax modem for performing data demodulation and demodulation over a public telephone network in accordance with the recommendation of CCITT T.30, and a scanning operation for transmitting predetermined text or image information. Scanning means, a fax output means such as a thermal transfer printer for receiving and outputting fax information received from a counterpart on a predetermined fax paper, and applying data for receiving and modulating transmission of demodulated data from the fax modem; In addition, the scanning operation and the fax output operation of the scanning means and the fax output means The fax control means that control is provided.

A television with such a fax function can transmit a predetermined text or image information through a public telephone network even while watching television without receiving a separate fax machine, and receives the received fax information through a fax paper. It is possible to confirm.

However, such a fax function television allows unrecognized fax information received through a public telephone network to be unconditionally received and output on predetermined fax papers without recognition of the other party. There is a disadvantage that the output to the fax paper is abused, and there is a disadvantage that the abuse of the fax paper is accelerated because the printing method through the fax paper is necessarily adopted even for the fax information having the content that needs to be received.

Accordingly, the present invention has been made in view of the above-described circumstances, and a fax selected by a viewer is displayed by displaying a reception state of a plurality of fax information received from the other party's transmission side in the form of OSD graphics and text on a television with a fax function It is an object of the present invention to provide a display processing apparatus which can selectively display the contents of the fax on the basis of information only.

In order to achieve the above object, according to the present invention, a fax information receiving status display processing apparatus for a fax function television, an image processing operation for a video signal of a television broadcast through an image processing means, and a television broadcasting through a voice processing means. A fax received through the character conversion operation of the fax information data through the fax signal conversion unit by performing a voice processing operation on the voice signal and performing a transmission / reception operation of the fax data via a public telephone network by the modulation / demodulation operation of the fax modem. A fax function television for outputting information on a fax sheet, comprising: fax output switching means for selectively switching to OSD-convert and output fax character data corresponding to a plurality of fax information from the fax signal conversion unit, and the fax output; A plurality of fax information applied from the fax signal conversion unit via a switching means Facsimile data memory means for storing fax text data according to the present invention, generation of OSD display information for checking reception status of a plurality of facsimile information stored in the facsimile data memory means, and predetermined fax information selected by a viewer's operation. OSD signal processing means for converting and outputting fax text data into OSD display text, and performing a selective operation for OSD converting predetermined fax information from a plurality of fax information stored in the fax data memory means to display the screen. Means and the reception setting according to the plurality of fax information received via the fax modem by the key operation of the function setting means and stored in the fax data memory as OSD display information, and the function setting means The OSD signal processing means such that predetermined fax information selected by It provides the received fax information consisting of hiyeo control means for controlling a fax function television status display processing device.
