Description

How to receive and receive faxes

The present invention relates to an emergency message fax transmission and reception method of a fax function television, and more particularly, to display a predetermined emergency message desired by a viewer in a television equipped with a fax machine capable of transmitting and receiving fax information through a public telephone network. The present invention relates to a method for transmitting and receiving an emergency message fax of a fax function television which allows a user to create a fax and transmit a fax to the other party, and to reproduce a screen of the emergency message received from the other party.

As is well known, in a typical television, a predetermined broadcast channel is selected from among a plurality of channels transmitted from a plurality of television stations, and the video / audio intermediate frequency conversion / amplification process and the demodulation process for each video / audio signal are performed, respectively. Can be played through the.

In addition to the playback function of television broadcasting, in recent years, a predetermined data format of an MMR format conforming to the daily format of CCITT T.4 and T.6 is recommended by using a communication connection with a counterpart through a public telephone network (PSTN network). A fax function has been employed to transmit and receive and to receive and output through fax paper.

In the facsimile function provided in such a television, a fax modem for performing data demodulation and demodulation over a public telephone network according to the recommendation of CCITT T.30, a scanning means for scanning to transmit predetermined text or image information, and a fax received from the other party. Fax output means, such as a thermal transfer printer, capable of receiving and outputting information on a predetermined fax paper, and applying the data for receiving and modulating the demodulated data from the fax modem, and scanning means and fax output means. And a fax control means for controlling the scanning operation and the fax output operation.

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, according to the television with such a fax function, in order for a user to create a predetermined urgent message and transmit it to the other party, the user scans and reads the paper on which the message is written through image scanning means provided in the television, and then converts the data into fax data. Since it is possible to transmit through a modem, not only takes a long time from the preparation of the emergency message to the transmission, but also the inconvenience of having to go through a multi-step message processing process.

Accordingly, the present invention has been made in view of the above-described circumstances, and after creating an emergency message as OSD display information on a television having a function of transmitting and receiving fax information, the created emergency message can be faxed and transmitted to the other party. It is an object of the present invention to provide an emergency message fax transmission / reception method of a fax function television that converts an emergency message received from a counterpart party received through a fax modem into OSD display information and reproduces the screen.

In order to achieve the above object, according to the present invention, an emergency message fax transmission / reception method of a fax function television has a video signal processing and playback function for a video signal of a television broadcast by a video signal processing unit, Fax function television with reception output function to predetermined fax paper through MMR decoding processing of received fax information through fax signal converting unit, which executes urgent message input function and has the user / vowel key and number provided in the function setting means. When the contents of the emergency message are inputted by operating the key, the contents of the emergency message inputted by the key operation of the function setting means are displayed as OSD display information and displayed on the screen. Communication connection with predetermined fax number by loading corresponding character code data and converting data as fax information OSD message corresponding to the emergency message transmission step for transmitting from the fax modem through the fax modem, and receiving the fax information of the emergency message from the other party through the fax modem, corresponding to the fax character data according to the MMR decoded emergency message. Provided is an urgent message fax transmission method of a fax function television comprising an urgent message receiving step of converting the OSD display information data into data and displaying the screen.

According to the present invention configured as described above, when a television having a fax function displays a predetermined urgent message desired by a user on a CRT screen in the form of an OSD display character, the created OSD display character information is displayed as fax data. In order to be transmitted to the other party through the fax modem, the fax information according to the predetermined emergency message received through the fax modem is converted into OSD display information data so as to be displayed on the CRT screen.
