DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention and is a schematic configuration diagram of a transfer data format transferred in the interface procedure according to the present invention.

Referring to FIG. 1, one embodiment of the present invention is
It is composed of an S1 unit 1, an S2 unit 2, a header unit 3, and each image data unit 4.

The S1 unit 1 shown here is for designating information necessary for the link configuration to the communication device, and S2.
The section 2 is information for designating image information and a processing method in the system. Further, the header section 3 indicates various kinds of information relating to the image data that follows, and each image data section 4 is
It shows color image data, monochrome image data, mask data (such as one expressing an image shape), and the like.

Further, FIG. 2 and FIG. 3 respectively show S1 part and S2.
It is the figure which showed one Example of the data structure of a part.

FIG. 2 is a diagram showing an example of the data structure of the S1 unit 1. For example, the operation designation 5 is the transmission system 12
By specifying a test operation or a communication operation from the communication device 14 (see FIG. 5) from the communication device 14 (see FIG. 5), the communication device 14 is made to judge the operation. Also destination TEL
No. Reference numeral 6 designates a transmission destination for the communication device 14, and FILE 7 designates the communication amount in the future for the communication device 14, and the receiving system 13 (see FIG. 5).
Also, the amount of data sent from the transmission system 12 is designated. Further, the user area 8 also specifies the content of the data transmitted from the transmission system 12 to the reception system 13.

As described above, the S1 unit 1 specifies the information necessary for the link configuration with respect to the communication device 14 and the receiving system 13.

Next, referring to FIG. 3, FIG.
Is a diagram showing an example of the data configuration of the image data. For example, the transmission data information 9 specifies information about image data, the type of image data (color, monochrome, mask, etc.), the arrangement of image data, the amount of image data, The attributes of the image data are designated, and the transmitter 14 and the receiving system 13 can know the information of the transmission data by this information. Further, the process designation 10 contains a process designation of the image data for the communication device 14, and this information allows the communication device 14 to designate, for example, whether or not to compress, or the content of the data processing. Further, the processing history 11 describes the result of data processing by the communication device 14, and the content of this allows the sending / receiving system to know the processing result of the data.

As described above, the S2 section 2 is for specifying the image information and the processing method in the system with respect to the communication device 14 and the receiving system 13.

Here, regarding the transfer data formats of the S1 section 1, S2 section 2, header section 3 and each image data section 4 described so far with reference to FIGS. 4A and 4B, only one screen is transferred. Then, the configuration in the case of multiple screen transfer will be described.

First, FIG. 4 (A) shows a transfer data format in the case of transferring only one screen. Prior to communication, S
As described above in 1st copy, 1 is specified in the FILE number 7 which is the number of communication screens. Therefore, when transferring only one screen, as shown in FIG. 4A, the processing ends with S1, S2, S2, header 3, and data 4.

FIG. 4B shows an example of a transfer data format in the case of transferring data of a plurality of screens. If image data of three screens is to be transmitted, the S1 unit 1 is used as described above. 3 is specified in the FILE number 7, and the S1 section 1 is transferred only once, and the S2 section 2, the header section 3, and the data section 4 are repeated three times.

The transfer data format in FIG. 1 is shown in FIG.
Although the configuration of the transfer data format in the case of single-screen and multi-screen transfer is described in the above, finally, the logical protocol of the interface procedure of the present invention will be described in FIG.

First, in FIG. 5, an example of sending out image data is represented by a transmitting system 12, and a side receiving the image data is represented by a receiving system 13. Further, it receives image data from the transmission system 12, performs arbitrary data processing by the S1 unit and S2 unit, and sends it to the communication line, or receives image data from the communication line and transfers the image data to the reception system 13. The portion is represented by a communication device (line) 14.

First, the S1 unit 1 is transferred from the transmission system 12 to the communication device 14. As described above, the information necessary for the link configuration is specified in the S1 unit 1, so that the communication device 14 can be connected to the communication device 14 of the other party through the communication line. F will be transferred. The receiving system 13 determines the contents of the S1 unit 1 in FIG. 2 and then returns the S1 response 15 to the transmitting system 12 via the communication device 14.

Upon receiving the S1 response 15, the transmission system 12 subsequently sends the S2 unit 2 to the communication device 14. Similarly, the receiving system 13 receiving the S2 unit 2 receives the S2
After judging the contents of the part 2 shown in FIG. 3, the S2 response 16 is returned to the transmission system 12 via the communication device 14.

The transmission system 12 which has received the S2 response 16
Next enters the header part transfer phase in the procedure, but transfers the header transfer request 17 to the receiving system 13 before transferring the header part 3. As a result, the receiving system 1
3 completes the preparation for accepting the header part 3 and then transmits the header transfer response 18 via the communication device 14 to the transmission system 12
Will be responded to. The transmission system 12, which has received the header transfer response 18, subsequently receives the header section 3 from the reception system 13.
When the header part 3 finishes transferring, the header END1
9 to the receiving system 13, and the receiving system 13
Upon receiving the header END response 20, the header part transfer phase is completed.

Subsequently, the data part transfer phase is entered, but the operation is exactly the same as the header part transfer phase, and as shown in FIG. 5, the data transfer request 21, the data transfer request response 22, the data END 23, and finally the reception. The system 13 sends a data END response to the transmission system 12 to end the series of procedures.

In the logical protocol of the present invention, when each transfer phase (S1, S2, header, image data part) is transferred from the transmission system, one transfer phase is completed to the reception system, and a response is sent. Is returned to the transmission system, and then proceeds to the next transfer phase. That is, it always enters the receiving system 13 and moves to the next transfer phase after receiving a response that the receiving system 13 is ready to receive the next phase.
