Abstract

PURPOSE:To extend the region of mutual communication between different medium terminals by detecting the receiving ability of a remote terminal in the communication of document information formed at a transmission side and converting the information of a terminal of the transmission side into the signal from received by the remote terminal in response to the receiving ability of the remote terminal. CONSTITUTION:When each terminal after call setting discriminates terminal ability each other, a transmission terminal sets automatically the communication mode in response to the ability of the receiving terminal. If the transmission side transmits a communication sentence formed by a character code and the remote terminal has no ability to receive the character, the transmission side converts the character code into a binary code and transmits it as a facsimile signal. In the conversion from the character code into the binary code, it is converted into the facsimile scanning line signal from the character dot matrix. This method is the same as that receiving the character code and recording and outputting it to a picture element type printer. The information formed at the transmission terminal is communicated as the facsimile signal converted to the binary code even if the remote terminal has no character receiving function and the area of mutual communication is extended.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a communication method that enables mutual communication with different types of terminals by converting signal formats.

If the information on one page is text, it is character code information, and if it is graphics, it is binary code information such as facsimile code. Mixed information of characters and graphics is transmitted first. This method requires that the receiving side also have the capabilities of the sending terminal. However, there are many devices, such as facsimile machines and teletex machines, that receive only graphic information or text information. Currently, Denki Nishishinset (#
The International Telegraph and Telephone Consultative Committee (hereinafter referred to as cc I TT), an international standardization organization related to ii, recommends that terminals such as benzuk teletex and basic facsimile should handle only character information or graphic information. . Furthermore, as mentioned above, terminals that can send and receive information that contains a mixture of text and 5 figures on one page are also permitted (hereinafter, these terminals are referred to as mixed mode terminals). In communication between mode terminals, either sending or receiving Gj needs to be done using the binary IJ n number in the case of facsimile, or by the character kanji number in the case of telex. In this case, if the receiving capability of the other party's terminal can be identified in advance by the calling operator who requests communication on the sending side 7u, it is possible to determine in which mode communication is possible prior to communication. As the number increases, it becomes impossible for an operator to fully understand the capabilities of the communication partner and set up a communication mote. This is particularly problematic when transmitting documents containing a mixture of characters and figures created by a mixed-mode terminal to a facsimile or teletex.

Conventional devices of this type have drawbacks such as when the sending side is a mixed mode terminal and the receiving side is a facsimile or teletex, communication becomes impossible because mixed information cannot be sent to the other party as a result of notification of reception capabilities between the terminals. was there.

FIG. 1 is an explanatory diagram showing an example of a conventional communication form,
In the figure, the rear indicates the sending side, the receiver indicates the receiving side, FAX indicates facsimile, TTX indicates teletex, MIXd mixed mode terminal, ■ indicates graphic information, T indicates character information, and T/I indicates mixed text/graphic information. There is.

That is, if the transmitter is a terminal that sends graphical information, the receiving terminal must be a facsimile or mixed mode terminal that handles graphical information processing.

If the transmitting side is a terminal that sends character information T, the receiving terminal must be a Teletex or Mixed terminal.

The sending side still handles mixed information T/1 of text and graphics ψ;
If it is an M terminal, the receiving terminal must be a mixed mode terminal.

With conventional communications, no other communication connections were possible.

However, depending on the recording format of the printer that receives the characters, or the method of printing with hemmers of matrix type, it is possible to express the type as a dot matrix and record the dots using a line scan method similar to a facsimile. , and the difference between printers and 7-axis receivers has almost disappeared.

Therefore, if a facsimile receiver can receive character codes and represent the character codes in a dot matrix, then it has the ability to receive character codes by facsimile.

Figure 2 shows an example of the communication format in this case, where the transmitting side sends character information T as teletex, and the receiving side has a character code/binary N code converter consisting of an IC connected to the facsimile receiver (= 1 converter). If the receiver is virtually transformed into a teletex receiver, the transmitting full+ teletex can be assumed to be that the other party communicated as teletex, but if the receiver only has the 772789 function, the As in the case of Figure 1, communication is impossible.

The present invention has been made in order to eliminate these drawbacks, and the document information created on the sending side is determined at the time of communication by knowing the reception capability of the other party's terminal, and depending on the receiving capability of the other party's terminal. It is a communication method characterized by the ability to convert information into a signal format that can be received by the other party's terminal, and its purpose is to expand the range of mutual communication between different types of media terminals, and the purpose is to expand the range of mutual communication between different types of media terminals. will be explained in detail.

Figure 3 shows an embodiment of the character/code information communication method according to the present invention, in which the communication range is increased by converting character codes to facsimile/inari codes at the transmitting terminal. be. In the figure, T* indicates character information that is converted from character code to binary code, T7* indicates the previous month when only character information in a document containing text and graphics is converted from character code to binary code, and other codes are This is the same as that explained in FIGS. 1 and 2.

This method is a communication method in which character information created by the operator before communication is automatically transmitted in a code format that matches the capabilities of the other party's terminal, depending on the function of the other party's terminal during communication. The sending terminal matches the functionality of the receiving terminal, and the receiving terminal does not require any conversion.

When communicating between a sending terminal and a receiving terminal, the boot code (communication protocol) between the two must match, l/-1.
゜In the above-mentioned CCITT, it was determined 1.1 that the protocol for teletex, data network fax 7mm, and mixed mode-1 terminals equipped with both functions should be a common protocol. . According to this common module, the operator does not have to consciously set whether the phase 1 terminal is a teletex, facsimile, or mixmote terminal. The functions of the other party's terminal can be automatically determined by the identification of It is possible to send the first message, but if the receiving terminal does not have the receiving capability, either the message will be sent according to the receiving terminal's receiving capability or communication will not be possible.In particular, text information will be sent to the other party's terminal. From the point of view of expanding communication, it is a great advantage for the transmitting terminal to match the receiving and 1111 terminal functions.

FIG. 4 shows a communication protocol in the present invention, in which the transmitting end is a terminal that expresses character information using character codes;
(B) is a transmitting terminal that creates character information using character codes, but converts the character information into graphic information according to the communication terminal function, and (C) creates character information using character codes and graphic information using binary codes. This shows the case where the terminal is capable of creating information, transmitting a mixture of both information, and converting text information into graphic information during communication.

Next, the mode setting procedure for communication at the transmitting terminal will be described. FIG. 5 shows the communication mode setting procedure of the transmitting terminal. The operator on the transmitting side does not take into account the terminal functions of the receiving terminal. After the call is set up, when the terminals identify the terminal capabilities, the transmitting terminal automatically sets the communication mode according to the capabilities of the receiving terminal. If the sender sends a message created in the previous month, and the other party's terminal does not have the ability to receive characters, the sender converts the character code into an inari code and sends it to the other party's terminal as a facsimile signal. As shown in FIG. 6, character dot matrix is converted into a 7-point, 7-millimeter scanning line signal to convert a character into a binary code. This method is the same as the method of receiving character codes and recording and outputting them to a pixel printer.

FIG. 7 is a diagram 122 of an embodiment showing the configuration of a transmitting section according to the present invention. Document information including created character information is stored in advance in the document information memory section 1. Communication When a call is set, the terminal uses the communication/terminal control unit 2 to identify the function of the other party's terminal.If the other party's terminal has a text reception function, the automatic mode switching unit 3 connects e-1), 1. Alternatively, the mode is set to mixed mode, and the automatic mode switching section 3 issues a command from the communication/terminal control section 2 to connect between c and b, and the document information memory section 1
The information stored in the first part is sent to the transmission path, but if the other party's terminal does not have a character receiving function, the communication/terminal control unit 2
A command for c-HI connection is issued, and only the character code information is converted into binary information by the code conversion section 4, and then sent to the other party's terminal as a full-page facsimile signal. The network/terminal interface section 5 controls the electrical signal level, impedance, synchronization, etc. between the transmission line (j) and the terminal section.

In this way, information from the transmitter can be communicated regardless of the function of the other party's terminal. In addition, the communication/terminal control unit 2
is configured by the microphone IJp1J Cenoza, and is performed by its control operation program. Sentence 1 Information memory section 1
is a part that stores created character information in the form of character codes, and when characters and graphics are mixed, graphic information is also stored.

As explained above, according to the present invention, even if the destination terminal does not have a character receiving function, the information created by the sending terminal can be converted into inari code and communicated as a facsimile signal, which is different from conventional communication. Since things that were impossible to communicate now become possible, the area of mutual communication will be expanded, and the effect will be very large. The cost of the code conversion section is just that of adding a ROM as a character matrix to the transmission section, so the cost does not increase much.Furthermore, since character codes are sent as binary codes, communication time increases, but communication The possible benefits are far greater and the practical effects are enormous.
