Abstract

PURPOSE:To compress communication data and to lower an error rate and a cost in communication information by transmitting and receiving data required for the generation of a command and a graphic to start up a graphic processing program. CONSTITUTION:In case of returning communication to the communication only of a character after the communication is shifted from the one of only the character to the one of graphic information and the communication of the graphic information is performed, a confirmation signal 1 to decide whether or not the communication of only the character is permitted to shift to the communication of the graphic information is transmitted from a transmission side. Next, when a confirmation signal 2 is returned from a reception side, the transmission side transmits a graphic processing picture plane start up signal 3 (command), and starts up a graphic processing picture plane at the reception side, and the command to generate the graphic and a signal 4 as data are transmitted. Following that, a graphic data processing completion signal 5 is transmitted to the reception side, and the reception side transmits a graphic data processing completion acceptance signal 6 for the signal 5. And finally, a character communication start up signal 7 is transmitted to the reception side, then, the communication is returned to the character data communication. In such a way, it is possible to compress the communication data, and to lower the error rate and the cost in the communication information.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a communication system using a word processor, in which graphic information is not transmitted or received as is (
The present invention relates to word processor graphic data communication in which graphic information is communicated by sending or receiving a command for starting a graphic program on a word processor of the other party and data necessary for creating a graphic.

[Conventional technology]

Conventionally, when transmitting or receiving graphic information, the graphic information itself was transmitted or received.

[Problem that the invention seeks to solve]

In conventional graphical information communication systems, a large amount of communication data is required, resulting in longer communication times, increased errors due to the increased amount of data, and increased communication costs. This invention was made to solve the above-mentioned problems, and its purpose is to reduce the amount of data for graphical information communication.

(Means for Solving the Problems) This invention creates commands and graphics for starting a graphics processing program existing on the other party's floppy disk in order to minimize data for graphics information communication. This is accomplished by sending or receiving the necessary data.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall view of an embodiment of the present invention, and in the figure,
(1) is a word processor, and graphic information is created on this word processor. (2) is a communication circuit, which sends and receives data created on a word processor to a communication cable. (3) is a communication cable, which connects the modem (4) and the communication circuit (2). (4) is a modem, and (5) converts digital information sent from a word processor into analog information.
6) is a communication cable that connects the telephone. (6) is a telephone set, and (7) is a telephone line.

FIG. 2 shows an example of transmitting graphic data created on a word processor using the method according to the present invention.

(1) is a graphic processing screen on a word processor. (2) shows an example of graphic data. When graphic data as shown in FIG. 2 is created, there are graphic processing program commands and data used to create this graphic data. In the example of FIG. 2, this includes a command to draw a circle and data indicating the properties of the circle, such as center coordinates and radius. In addition, drawing boundary lines (commands and angular data as information indicating the position of the boundary lines) necessary to create a pie chart are used, but these are sent as communication information to the other party's word processor, and It is possible to perform similar graphical processing on a word processor.

FIG. 3 shows an example of the flow of processing when the communication shifts from text-only communication to graphic information communication, and then returns to text-only communication after communicating graphic information.

Signal (1) is a confirmation signal indicating whether it is okay to shift from text-only communication to graphic information communication, and waits for confirmation signal (2) from the receiving side. When signal (2) arrives, the sending side sends the graphic processing screen start command of signal (3), and the receiving side's graphic processing ii! Activate the i-plane, send the graphic data of signal (4), and send the program command for creating a graphic and the data necessary for creating the graphic to the receiving side. Signal (5
) is a signal indicating the end of the graphic data □, and in response to this signal, the receiving side sends a signal (6) to acknowledge the end of the graphic data. Finally, a character communication activation command of signal (7) is transmitted, and the process returns to character data communication.

(Effect of the invention) In a communication system using a word processor, graphic information is communicated not by transmitting or receiving graphic information as is, but by transmitting or receiving a command to start a graphic program on the other party's word processor. Therefore, communication data can be shortened, and as a result, the error rate in communication information can be lowered, and costs can also be reduced.
