Description

Processing method for service of displaying PC document to the mobile terminal

The present invention relates to a processing method for a service for displaying a document created by a PC on a screen of a mobile terminal.

If you need to provide a simple document such as a receipt or medical certificate or a complex document such as a report to the customer, you need to fill out the document on a PC and print it in writing and deliver it directly to the customer or fax it. And because of the fax operation takes a lot of time, because it is delivered in writing from the customer's point of view it is not easy to keep.

In order to alleviate the inconvenience of printing and faxing, PC documents (hwp, doc, pdf, ppt, xls, etc.) that have been created are attached to e-mails and sent to others. It can be downloaded and printed or viewed on a PC monitor.

However, the PC documents transmitted via e-mail cannot be seen without the PC, and other people on the move cannot see the PC documents.

In view of the problems of the prior arts, the present invention provides a processing method for a service that transmits a PC document to a mobile terminal (mobile phone, PDA, etc.) so that others on the mobile can view the document transmitted through the screen of the mobile terminal. to provide.

In one embodiment of the present invention for achieving the above problems,

In the method for sending a PC document to the mobile terminal to display on the screen,

Transmitting the PC document to be transmitted to the mobile terminal and the number of the mobile terminal to the service server; At the service server, forming a reduced font file corresponding to a font used in the transmitted PC document; Forming, at the service server, a document for a mobile terminal in which the position of each font in the reduced font file is assigned to each character; Transmitting, at the service server, the reduced font file and a document for a mobile terminal to a mobile terminal corresponding to the number of the mobile terminal; And extracting a font corresponding to each character of the document for the mobile terminal from the reduced font file and displaying the font on the screen by displaying the document for the mobile terminal on the screen.

Now, the configuration and overall operation of the present invention will be described with reference to Figs.

First, the sender 1 who wants to send a PC document connects to the service server 3 through the PC 2 via the Internet and performs a subscription procedure, receives an ID and password, and receives a payment method (credit card, If the mobile phone bill, etc.) is selected (S1), this information is stored in the subscriber DB (not shown) (S2).

Next, when the sender 1 wants to deliver a document (receipt, medical certificate, document, etc.) to the receiver mobile terminal 5, the sender creates a document through the PC 2, for example, "Document 1". .doc ", and then (S3), access the service server (3) via the Internet, enter the IP and password to be authenticated (S4), and pass the authentication process, the service server (3) is shown in Figure 4 A screen as shown in the above is displayed on the screen of the PC 2 of the sender 1, the sender's name ("Hong Gil Dong"), the recipient mobile terminal number ("011-9876-5432"), and the attachment file name ("Document"). 1.doc ") to enter (S5), and select a transfer button (S6). In this case, the "document 1 .doc" file is read from the sender 1's PC 2 and transferred to the service server 3 (S7).

Now, the service server 3 checks the extension (doc) of the received file and transfers this doc file from the conversion server 6 to the receiver mobile terminal 5 (hereinafter, the extension for this file format). Is converted into "dmd" (S8). A detailed conversion method is described in detail with reference to FIG. 6 below.

The file ("Document1.dmd") converted to the dmd file type is described in Figure 5 together with the sender's ID ("honggildong") and the receiver mobile number ("011-9876-5432"). After being stored at 7 (S9), the SMS server 8 receives the recipient mobile terminal number (011-9876-5432) from the content server 7 and transmits a text message indicating that the document has arrived at this number (S10). ). The receiver receiving the text message downloads the "document 1.dmd" from the content server 7 by pressing a call button or a specific key in the mobile terminal 5 (S11). In this case, the SMS / MMS push method may be used as the download method, and the MMS method may be used to download immediately without transmitting the arrival text message.

Thus downloaded "document 1.dmd" is automatically displayed on the screen of the mobile terminal 5 by the viewer (Viewer) program (S12). At this time, if the viewer program does not exist, the mobile terminal 5 accesses the content server 7 again, downloads the viewer program, and automatically executes it to display "Document 1.dmd" on the screen (S13).

In this way, the document sent by the sender 1 is displayed on the mobile terminal 5 of the receiver.

On the other hand, since the size of the screen of the mobile terminal 5 is small and most of the downloaded mobile terminal documents cannot be displayed, such a viewer program (e.g., FileViewer of Picsel) can move the previous / next page function and enlarge the document. It should have a zoom in / out function, scroll up, down, left and right.

Next, a process of converting a PC document into a document for a mobile terminal in the conversion server 6 will be described with reference to Figs. 6-11.

First, PC documents in various formats (doc, hwp, etc.) are converted into pdf files.

For example, a doc file can be converted to a pdf file using Acrobat's pdf generation function, an offline conversion tool, or using Acrobat's online PDF generator, an online conversion tool. The hwp file is converted into a pdf file by ezPDF Gate or Hancom PDF Converter program of Hangul and Computer. The document name thus converted is "Document 1.pdf".

Next, the converted pdf file should be converted into a file format (dmd file) for the mobile terminal.

The pdf file contains not only text data but also image data and a drawing command.

Since the image data of the pdf file is encoded in jpg or pmb, and the mobile terminal for the present invention has a built-in or downloaded and existing decoding program (not large in size) for decoding such image data in jpg or pmb format. The image data of the pdf file can be used as it is.

In addition, since the drawing command is not very large, the shape of the command can be changed slightly, but it can be used without any special change.

The problem is text data. Even though the text is the same character, the font size and size are different, so it is possible to store the font data (characters of several tens of megabytes) of various fonts and sizes in the memory of the mobile terminal. not. Therefore, there is a need for a special method of reducing the size of character font data.

To this end, the present invention uses a method of including only the font for the character used in the pdf file in the dmd file. This method will now be described in detail.

As shown in Fig. 6, a letter A of size 11, a letter B of size 12, a letter 13 of size A, a letter C of size 12, and a letter B of size 11 Is explained on the first line, and the second line contains a letter of size 12 (B), a letter of size 11 (A), and a letter of size 13 (C). Here, the positions of the font images for the letters A, B, and C having respective sizes are as shown on the left of the font table T shown in Fig. 7, for example, the letter A (A (11) Assume that font data for)) appears in the 97th position of the font file.

Now, in the pdf file (Document 1.pdf), the first character (11-size alphabet letters (A): A (11)) is read (S21). The font corresponding to this character is found in the font table T, and the position (1, 1) of this row / column is recorded (S22) (see the first row in Fig. 7).

Then, the position 97 in the font table T of this font is also recorded in the read character A (S23) (refer to the beginning of the first line in Fig. 8).

When the above process is repeated, the converted font table T as shown in FIG. 7 and the first converted text as shown in FIG. 8 are formed (S24).

For example, in Fig. 7, the first line means the font image for A11, which is the letter A of size 11, in the 97th of the font file, and this letter (A (11)) is a PC document. The second line means the font image for A (12), a size 12 character (A), in the 98th of the font file, and this character (A (12) means not used in PC documents.

As a next step, the font images corresponding to the fonts A12, B13, and C11 that are not used in the font table T in Fig. 7 are deleted from the font file and the reduced font table RT (Fig. 9) to form (S25).

For example, if a font image for an unused font A 12 is deleted from a font file, the reduced font table RT (FIG. 9) originally had A (12) at 98, but (98). A (13) is present.

This process is also performed for the remaining unused fonts B13 and C11 to complete the reduced font table as shown in FIG.

Next, using the reduced font table, the primary converted text of FIG. 8 is converted into secondary converted text as shown in FIG. 10 (S26).

When the above process is performed, the reduced font file (RF) contains only the font data used in the PC document to be transferred, so the size is reduced to several tens of kilobytes and stored in the memory of the mobile terminal. Is reduced.

In addition, since the positional data of each character in the reduced font file exists in the secondary converted text (dmd file), the reduced font file and the secondary converted text are formed into one file to the content server 7. After saving and transmitting to the mobile terminal 5, the mobile terminal 5 reads the secondary text through the viewer program, finds the corresponding font in the transmitted reduced font file, and displays it in sequence on the screen. The created document is displayed.

At this time, since the conversion server 6 holds the specification data for each mobile terminal number, the available memory size of this mobile terminal can be known.

Therefore, when the reduced font file and the secondary converted text exceed the available memory size, the secondary text is divided into a plurality of secondary text files, stored in the content server 7, and stored in the mobile terminal one by one. Send it.

Next, I will briefly explain the viewer program.

A file viewer program for displaying a document on the screen may use, for example, a PixelView FileViewer or a dedicated program.

Such file viewer program should have the following basic functions so that users can use it conveniently.

1. Ability to move to the previous, next, first, last, desired page

2. Zoom in / out function and maintain previous position when zoom in / out

3. Screen scroll function

4. Contents view and bookmark function

On the other hand, because it is a document for a mobile terminal, if the following additional functions can be used by the user more conveniently.

1. The screen of PC monitor is longer than the width of the screen, but the screen of the mobile terminal is longer than the width of the screen.

2. By adding a function that remembers the last point where the cursor was placed on each page, by automatically moving the cursor to the corresponding position when moving the page, it can reduce the trouble of finding the point where the cursor was previously located.

3. In order to solve the inconvenience of excessive use of the scroll button due to the small size of the screen, the automatic scrolling function is provided at a preset speed until the specific auto scroll stop button is pressed in the direction specified by the user through key input or the like. It is good to have it scroll automatically. At this time, when the right end of the screen is reached to automatically move to the left end.

Although preferred embodiments of the present invention have been described above, it should be noted that the present invention is not limited to this embodiment, but various modifications can be made without departing from the spirit of the present invention described above.

For example, in the above description, when the sender selects and transmits an arbitrary PC document, the conversion server 6 converts the file into a pdf file. However, the sender can convert the PC file into a pdf file and transmit the file.

By using the present invention as described above, by transmitting a PC document to a mobile terminal, the other person on the move can see the document transmitted through the screen of the mobile terminal.
