Abstract

PURPOSE:To improve a transfer speed of a whole integrated document by providing data file identification information constituting the integrated document and selecting a file transfer protocol corresponding to the attribute of a data file by means of identification information. CONSTITUTION:Identification information is given to the respective data files of control information, text data, a graphic and a picture, which constitute the integrated document. At the time of transferring the integrated document, a central processing unit 1 judges the identification information, selects the file transfer protocol corresponding to the character of the data file concerned and transfers the file. Namely, the file consisting of a text and graphic data, which generate serious influence by a slight error, is transferred by the protocol having a highly precise correction function, and the file consisting of picture data which can allow the slight error is transferred by the protocol having the correction function of low precision. Then, the integrated document is transferred from a communication control part 6 via a telephone network 8.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated document file transfer system in an information processing apparatus having an integrated document editing function and a function of transferring the integrated document via a telephone network.

[0002]

2. Description of the Related Art With the improvement of Japanese document processing technology,
Japanese document editing devices (Japanese DTP, Japanese word processor) that can create and edit integrated documents composed of multiple data files such as texts, figures, and images have been commercialized.
Further, among these products, a device having a communication function and a function of transferring created integrated documents between the same devices is also realized.

However, when transferring an integrated document composed of a plurality of such data files, the protocol used for each file transfer is the same, and the type of information (text, figure, image, control information, etc.) that constitutes the file is the same. ), It was not possible to selectively use the file transfer protocol. As a result, even a small data error causes serious problems. Even for data files with relatively small file size control information, text, graphics, etc., some data errors do not lead to serious problems. Even for a large amount of image data file, the file transfer is carried out by the same error checking and resending mechanism, so that the file transfer adapted to the character of the data cannot be realized.

[0004]

An integrated document including image data may have a size of several megabytes, and when transfer processing is performed via a telephone network by a standard file transfer protocol, the transfer time is , For example, may range from several tens of minutes to an hour.

As described above, in the conventional integrated document file transfer method, when transferring each data file forming an integrated document, it was not possible to select and handle a protocol according to the character of the data file. Therefore, the transfer speed of the entire integrated document cannot be improved.

It is an object of the present invention to solve the above-mentioned conventional problems and to improve the transfer speed of the entire integrated document by selecting a protocol according to the character of the data file forming the integrated document. ..

The operation of the information processing apparatus of this embodiment having the above configuration will be described below with reference to the flowchart of FIG.

The central processing unit 1 transfers the integrated document to the telephone network 8 via the communication control unit 6 together with the text file name designated by the user by the input control unit 3 and the control information and the text data. The file shown in Fig. 3
(1) Open 13 (S1), determine the number of data files (text data file + 3 = 4) that make up the integrated document in the control information, and transfer the transfer file name registration table shown in FIG. The number of transfer data files is registered in the file number area 50 (S2).

Next, the text data of the body file is searched, and in addition to the body file name, the transfer file name 51 of the sub data files (2) to (4) linked from the body file (1) is transferred. Register in the file name registration table
(S3).

After the search of the sub data file from the text data of the body data file is completed and the registration of the transfer file name registration table shown in FIG. 5 is completed, the body data file is closed (S4), The file transfer process of the data files forming the integrated document is started for each file.

First, the central processing unit 1 determines that there is a file to be transferred based on the number of transfer files = 4 in the transfer file name registration table (S5). Hereinafter, the transfer process for each file is repeated until the number of transfer files = 0.

First, from the transfer file name registration table,
The file name of the file (1) 13 is taken out and the data file is opened (S6). Next, with the identifier 13A at the beginning of the file, the body text data file 13
The attribute of the fact that it is is determined (S7), and the file transfer process by the protocol A is executed (S8). Here, as shown in FIG. 6, the protocol A is a file transfer protocol having a CRC / CCITT error check system and 10 times of retransmission when an error occurs. Errors in data transfer, such as text data, can have a significant impact,
Protocol A is applied to a relatively small capacity data file, and control is performed to minimize the occurrence of data errors. After the transfer of file (1) 13 is completed, the file
(1) 13 is closed (S10), and the number of transfer files in the transfer file name registration table is decremented by 1 (S11). As a result, the number of transfer files = 3, and after determining that there is a file to be transferred (S5), the next file transfer process is started.

Similarly, for the file (2) 14, the data file OPEN (S6) and the data file attribute determination (S7) are performed. Similar to the case of the file (1) 13, since the attribute of the file (2) 14 is the text file, the file transfer by the protocol A is executed. File (2)
After the transfer of 14 is completed, file (2) 14 is closed.
(S10), the number of transfer files in the transfer file name registration table is decremented by 1 (S11). As a result, the number of remaining transfer files = 2
After determining that there are files to be transferred,
Starts the next file transfer process.

Similarly, for the file (3) 15, the data file OPEN (S6) and the data file attribute determination (S7) are performed. In the file (3) 15, information as a graphic file is defined in the identifier 15A, and the protocol A is the same file transfer protocol as the text data.
File transfer using is executed (S8).

After the transfer of the file (3) 15 is completed, the file (3) 15 is closed (S10) and the number of transfer files in the transfer file name registration table is decremented by 1 (S11). As a result, the number of remaining transfer files = 1, and after determining that there is a file to be transferred, the next file transfer process is started. Similarly, data for file (4) 16
File OPEN (S6), data file attribute judgment
Perform (S7).

In the file (4) 16, information as an image file is defined in the identifier 16A, and the file transfer process by the protocol B is executed (S9). Here, as shown in FIG. 6, the protocol B is a file transfer protocol that does not have an error check method and has 0 times of retransmission when an error occurs. Protocol B is applied to large-capacity data files that do not have a serious effect due to errors during data transfer, such as image data, and high-speed file transfer is possible while allowing the occurrence of data errors. Take control.

After the transfer of the file (4) 16 is completed, the file (4) 16 is closed (S10), and the number of transfer files in the transfer file name registration table is decremented by 1 (S11). As a result, the number of remaining transfer files becomes 0, and after determining that there is no file to be transferred, the transfer processing of this integrated document is ended (S12).

[0028]

As described above, according to the integrated document file transfer method of the present invention, a highly accurate error correction can be performed for a file including text and graphic data, which causes a serious change in information even if a slight error occurs. Performs file transfer using a file transfer protocol with functions,
For files consisting of image data that can tolerate some errors, by performing file transfer using a file transfer protocol that has a low error correction function, it is possible to reduce the transfer time while transferring the entire integrated document. The influence of data transfer error can be kept low.
