Abstract

PURPOSE:To reduce the data volume of document information and to shorten the data transmission time by expressing the continuity of one-character spaces or the same characters or symbols with a code indicating the continuity of them and a code indicating the number of continuance of them. CONSTITUTION:The format (omitted in the figure) encoded with only format control functions defined by 'Japanese telex equipment recommending communication system' and the format encoded by this inverted method as shown in the figure are compared with each other. When spaces corresponding to 5 characters are continuous from the start character position of a line like a line l3 and l16, they are expressed with 'ESP', 'SP, and '5' in the invented method and the data volume is reduced by a data volume (normally two bytes) corresponding to two-character code data in comparison with the conventional method though 5 'SP's are continuous in the conventional method. When 10 one-character spaces are continuous from the start character position of a line like lines l6, 7,...15 and lines l17, l18..., the data quantity is reduced by a data quantity (normally, 7 bytes) corresponding to 7-character code data.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a teletex device for communicating documents by connecting a terminal having a word processing function to a communication line. Regarding control method.

[Prior art]

In recent years, word processors have been rapidly gaining popularity, but when document information created with word processors is to be used in a remote location, it has traditionally been necessary to store document information as code data on a floppy disk, etc. Methods such as transporting a medium, printing it as a heart copy and then transmitting it using a facsimile machine, or using an acoustic coupler to transmit and receive the information via a telephone line have been adopted. However, the first method of transferring the floppy disk requires time to transfer, and is therefore not suitable for emergencies. Sending the second hard copy by facsimile is uneconomical as it requires re-entering the word into the word processor at the receiving end.

The method of transmitting and receiving using the third acoustic coupler requires converting code data representing character information into an acoustic signal on the transmitting side, and reloading the sound mouth signal into yaw 1' data on the receiving side. Moreover, in the case of an acoustic signal, the transmission time is long due to its communication capacity, and furthermore, it cannot be said that it is perfect in terms of reliability.

Under these circumstances, the Teletex device was developed as a device that made it possible to send document information input and created on a word processor as code data directly to a word processor in a remote location via a communication line. has been done.

[Problem that the invention attempts to solve]

By the way, the format control method of the above-mentioned teletex device is as follows.
It was announced as ``Recommended communication method for Japanese Teletex equipment'' in ``Postal Bulletin Special Issue No. 14'' published by the Ministry of Posts and Telecommunications dated November 12, 1981.

In this "Recommended Communication Method J for Japanese Teletex Equipment," format control functions are defined, for example, code 1.F for line feed and code "FF" for page feed (page break). blank spaces or identical characters,
The format for consecutive symbols is not defined; for example, if there is a certain number of consecutive spaces at the start of a line, and then a character is written, the format for consecutive symbols is not defined. The blank code SP'' is repeated as many times as necessary. Therefore, for example, in a document with a layout where the heading is written near the left edge of the page and the main text is written near the right edge, the blank code SP'' is repeated in the lower part of the heading. Because there are a wide range of blank spaces, it is necessary to send only nine single-character blank codes "SP" as described above, and the actual amount of document information is small compared to the amount of data. , the disadvantage is that the transmission efficiency is low.

This situation applies not only to consecutive blank spaces at the beginning of a line, but also to consecutive blank spaces or identical characters or symbols in the middle of a line.

[Means for solving problems]

The present invention has been made in view of the above circumstances, and
In the format control method of teletex equipment, a series of spaces for one character or a series of the same characters or symbols is defined as a space for one character or each character.

A format control method for a teletex device that aims to eliminate the above-mentioned drawbacks by representing a code that indicates that symbols are consecutive, a code that indicates the number of consecutive symbols, and a code that indicates that such special control is to be performed. The purpose is to provide.

The present invention provides a format control method for a teletex device in which input character information is transmitted and received as a code data to and from each other via a communication line. Or, it is characterized by indicating that each character or symbol is consecutive: expressed by a code indicating the number of consecutive letters or symbols.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

FIG. 2 is an example of a document for explaining a format control method for a teletex device according to the present invention. First, we will explain the layout of this document and the format diagram in Figure 3 when it is encoded using only the format control function defined in the "Japanese Teletex Equipment Recommended Communication Method" published by the Ministry of Posts and Telecommunications mentioned above. .

In addition, in the following explanation, the characters enclosed in "" represent ko 1-°.

At the left end of the page of the document, a binding margin of 1.1 is set as a blank space of five characters on the left and right over the entire downward direction of -L of the page. Since this binding margin L1 is automatically set by format control, it will not be discussed in the following description.

A two-line margin is set at the top of the page of the document. That is, since the first line ρ1 and the second line e2 are all blank, it is only necessary to perform line feed format control.

In the formant diagram in Figure 3, the codes in the first and second lines 11 and 2 are all blank, that is, there is a line break at the beginning of the line, so they are each composed of two code dates, the codes "CR" and "LF". has been done. Note that the code "C12" is one of the format controls meaning "return" and represents moving the operating position to the home position on the same launch. Further, the code "LF" is one of the format control functions meaning "line feed", and represents moving the operating position to the next line.

The third line 13 of the document has 5 spaces at the beginning, followed by rTEs as the title of this document.
The four characters "Tj" are written, and after that, there are blank spaces again, and a new line is immediately inserted.

In the format diagram in Figure 3, the code in the third line 13 is
First, the blank code "SP" for one character is continuous for 5f,
The characters IT E actually entered in the document after that
The respective codes “T’,” “E” representing the four characters of S TJ
”, “S” and “T” are arranged, followed by the above-mentioned first .
2 Codes for line breaks similar to 1.2 “CR”, “L”
It is composed of "P".

In the fourth line 14 of the document, the entire line is blank, as in the above-mentioned first and second lines 11 and 2, that is, a line break is made at the position of the first character of the line.

In the formant diagram of FIG. 3, the code in the fourth line I24 is also the code in the above-mentioned line 1.2 I! 1.2 Similarly, the code “C”
It is composed of two codes: "R" and "LF".

In the fifth line 7!5 of the document, five characters rl and ABCJ are entered as headings starting from the first character position of the line, and after that, a line break is made.

In the formant diagram in Figure 3, the code in line 5, line 15, is
Characters r1 written in the document. Codes “I”, “, ′, “A1.” representing ABCJ. The code is composed of "B" and "C" in this order, and the codes "CR" and "LF" are composed for the subsequent line feed.

Each line #6 below the 7th line 17 of the document. N7...The main text is written in each. That is, a blank space of 10 characters is set in the bright part of each line, and the main text is written starting from the 11th character after each line. The main text is
For example, the sixth row 16 contains "01234..." and the seventh row I17 contains r12345...". In addition, each line I from 8th line 48 to 15th line 7!15
! B, pg...Li2 also have similar configurations.

In the formant diagram in Figure 3, the code in line 6, line 16, is
10 blank codes "sp" for one character are arranged consecutively, followed by codes "0", "1", which represent the characters "r01234..." written in the actual document,
It consists of "2", "3", "4", etc. in order, and finally consists of codes "CR" and "LF" for line feed.

Each line below 7th line 17 I! The same applies to B, pg, and so on.

Then, the 16th line 216 becomes a heading line again, and like the 6th line z6 described above, [2
, DEFJ, and a new line after that.

And each line 7!17 below the 16th line 7!16. l
118...A space of 10 characters is set at the beginning of each, and from the 11th character after each, the main text rabcde...'', rbcdef...'',...
is entered.

In the formant diagram in Figure 3, these 16th rows 7!16 and following rows 1216. Regarding Li7..., the above-mentioned 6th line 16 and each subsequent line I! 7... basically has the same chord structure.

FIG. 3 is a format diagram showing the format when the above-mentioned document is converted into code data using the method of the present invention.

The first line 11 and the second line 12 are all blank, that is, there is a line feed at the beginning of the line, so they are represented by two code data, "CR" and "LF", respectively, which are explained above. The format is similar to the format diagram in Figure 3.

Third line! 3 has 5 blank characters followed by the 4 characters rTEsTJ, so first of all, it is used as a code to indicate a blank or a series of the same characters or symbols as "ESP" (the above-mentioned "Japanese Teletex" published by the Ministry of Posts and Telecommunications). "Recommended device communication method"
After this code "ESP" is a code that specifies one consecutive space, character, or symbol, that is, in this case, one character. The codes are arranged in the following order: the code "'SP", which represents consecutive blank spaces, and the code "5" (different from the normal code representing the number 5), which represents the consecutive number, after this code "sp". After each of these codes, there are codes "T", 'E', and "S" representing the four characters of the characters rTESTJ actually written in the document.

T" follows each, and finally "CR" for a line break.

Codes of “1.F” are arranged.

Since the fourth line 14 is all blank, that is, there is a new character at the beginning of the line, the code "CR" is written in the same way as lines 11 and 2 of the
' and "LF".

In the fifth line 15, the characters r1. which are written for five characters from the first character position of the document. Code representing ABCJ “
1'', ``,'', A'', ``B'', and ``'C'' are arranged in this order, and codes ``CR'' and ``LF'' are arranged for subsequent line breaks.

In the sixth line 16, as in the third line 13 above, "ESP" is a code indicating that a blank or the same character or symbol is a continuous control, and after this code "ESP" there is a blank. The code "'sp'" to indicate consecutiveness, followed by the code "10" to indicate the number of consecutive numbers (normal number 10).
``O'', which represents the characters written in the actual document after that,
"1", "2", "3", "4", etc. are arranged in order, and finally, the codes "C12" and "LF" are arranged for line feed.

Each line from the 7th line 7!7 to the 15th line 115 7!8...
- The same applies to β15 as for the sixth row 16 described above.

Then, each line 16. after the 16th line/+6. tJ7・
...Then again, each line 65,746 from the 5th line 15 onwards.
...is processed in the same way.

Therefore, the document shown in FIG. 2 is encoded using the format diagram of FIG. 3, which is obtained by encoding only the format control function defined in the "Recommended communication method for Japanese Teletex equipment", and the method of the present invention. Comparing this with the format diagram in Figure 1, we can see that when a single character's blank space or the same character or symbol is consecutive (the document in Figure 2 shows an example of a case where there are consecutive blank spaces from the first character position of the line) According to the method of the present invention, if there are five consecutive blank spaces from the first character position of the line, such as lines 13 and 16 in the 3rd and 16th lines of the document shown in Figure 2, this corresponds to 2-character code data. The amount of data (usually 2 bytes) is reduced, and
line! ! 6.7...15 and 17.18...row 11
7, 1 from the first character position of the line, such as i'18...
In the case where there are consecutive blank spaces for 0 characters, the method of the present invention reduces the amount of data (usually 7 heights) corresponding to 7 characters of code data.

〔effect〕

As detailed above, according to the present invention, in the format control method of a teletex device, it is possible to reduce the amount of document information by 11 in the case of one character's blank space or consecutive identical characters or symbols. becomes.

This is particularly effective in reducing the amount of data and data transmission time for documents with many blank spaces from the first character position to the middle of the line. In addition to spaces, the same effect can be expected when the same characters or symbols are repeated, for example, when a figure is created by consecutively "-".

In the above embodiment, since the "Recommended Communication Method for Japanese Teletex Equipment" issued by the Ministry of Posts and Telecommunications uses a special control code that is not temperature controlled, the Teletex Nox on either the transmitting side or the receiving side is used. Of course, the device must also be able to use it.
