The present invention relates to a text message combined with a font codec, and a system and method for transmitting the same. More specifically, a font codec combined with a font codec for displaying a message written in a font designated by a sender of a text message as it is is displayed on a receiver's terminal. Text message, and a system and method for transmitting the same.

In addition to voice calls, mobile phones are often used for text message transmission or Internet access. Recently, younger students are actively expressing their opinions through text messages (SMS, MMS).

In the early days of the spread of mobile communication technology, text message transmission, which was only outputting text, evolved into a combination of various fonts, colors, and shapes, thus acquiring more users.

In the text message transmission method using a mobile communication user terminal such as a handset phone, a message written through a message client program mounted on the terminal is transmitted to a receiver's user terminal through data transmission according to the standard of the mobile communication network.

In the text message transmission according to the prior art, in order to deliver the font design constituting the sentence to the counterpart, the text must be converted into an image. In other words, the contents of the message expressed in a specific font are converted into image data, and the contents of the message converted into images are transmitted to the receiver as it is and output.

This method has the advantage of sending various types of fonts to the receiver. However, when the output status (LCD window size, aspect ratio, etc.) of the sender and the receiver's terminal are different, There was an issue that could not be shown.

For example, if a sender composes a message at a typical 4: 3 aspect ratio, images it, and sends it, but the receiver is using a terminal with a 16: 9 aspect ratio, the receiver cuts off part of the message sent by the sender. You have to look at the screen, or see a text message with some space on your screen.

Therefore, there is a problem that the utility of the text message is reduced because the sender can not deliver the intended appearance to the recipient.

Recently, a service for allowing a user to express various types of fonts while selling font implementation programs sold by each mobile communication company in addition to the fonts basically mounted on a mobile phone has been disclosed.

However, even in the case of using such a service, each user must access a site that sells the corresponding font implementation program, and purchase and install the program. However, each user must purchase the program each time a text message written in a new type of font is required. There was a problem.

The present invention has been made to solve the above-mentioned problems, by encoding a font that displays a special font to be coded and transmitted to the text message through the mobile communication network so that the receiver can see the text message as sent by the sender at any time It is an object of the present invention to provide a text message in which a font codec is combined and a system and method for transmitting the same.

In addition, the present invention does not cut or blank the screen even if the terminal screen configuration of the sender and receiver is different, combined with the font codec to enable the display of the kerning, line spacing, line breaks, etc. suited to their screen It is an object of the present invention to provide a text message and a system and method for transmitting the same.

Hereinafter, a text message transmission system according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Example 1

1 is a conceptual diagram illustrating a structure of a font codec coupled to a text message of the present invention, and FIG. 2 is an exemplary diagram illustrating a method of generating font data.

In the text message of the present invention, a font codec capable of implementing a font written by the sender is embedded together, and the user terminal of the receiver receiving the text message in which the font codec is combined executes the font codec. The caller specified fonts can be viewed on their terminal. In other words, the font glyph data output on the screen is coded as it is and combined with the text message.

In addition, the font codec of the present invention is prepared in MDF (Mobile Data Font) format, which is a dedicated font file considering a wireless memory environment and hardware memory specifications of a user terminal for use of various font designs when transmitting a message on a wireless Internet through a mobile communication network. do.

The core of the present invention is to embed the font into the message codec data in the message client of the mobile phone. To implement this, a technique for reducing the data size of the message font format is required.

MDF format is a format for exclusive use of the wireless Internet. It conforms to KSC5601 and Unicode 4.0, and has the same Hangul font standard as the existing Windows font (TTF).

In addition, the average capacity of the MDF format is about 200KB, which can compress up to 150KB.

As shown in FIG. 1, the structure of the font codec 10 according to the embodiment of the present invention includes a header 11, a font identifier 12, data length information 13, and glyph length information. glyph 14, font data 15, and glyph data 16.

The font codec 10 is a codec of data information constituting the phoneme of a specific font, and is combined with data of a text message and transmitted to the receiver.

The header 11 is a portion in which the essential information of the font codec 10 is recorded, and a name for identifying the font is recorded in the font identifier 12, and has a size of about 4 bytes. In the present invention, an identifier called EMDF (Embeded Moble Font Data) is used.

The data length information 13 stores information on the total size of data embedded in the text message, and the grip length information 14 stores information on the number of embedded characters.

The data length information 13 and the grip length information 14 each have a size of about 2 bytes.

The font data 15 exists by the number of embedded characters for each font codec 10. The font data 15 is composed of code, width, and offset.

Code is the standard code value of Korean used in the message and it means the code value of KSC5601 or Unicode.

The width is the variable width of the character, which means the width size value of the vector font kanji.

The offset is a vector font data value, and means an entire data value (stroke length, height, rotation angle value, etc.) for a glyph data value representing a single character of the vector font.

2 shows an example of generating the font data 15.

In order to output a character having a specific font, the glyph data 16 of the font element is marked at a point on the pixel position constituting the mobile phone screen. Through the output function of the font glyph data 16 in units of pixels, the design elements of the font can be reconstructed as they are.

As shown in FIG. 2, when the letter 20 of size B is rendered, the following results are obtained.

{image-> width: 13

image-> bbox.ox: 1

image-> bbox.oy: 1

image-> bbox.sx: 12

image-> bbox.sy: 17

image-> data

NNNNNNNNN000

NN0000000NN0

NN00000000NN

NN00000000NN

  .....

NNNNNNNNN000}

These result values are combined with the message data making up the content of the text message and sent to the receiver.

When the caller creates a text message using his mobile phone, the message client creates message data in which the text content entered by the caller is recorded. When the caller selects a specific font, the font codec 10 previously stored in the mobile phone is combined with the message data to generate a 'font embedded text message'.

The text message combined with the font codec is transmitted to the receiver through the mobile communication network, and the receiver's mobile phone can extract and recombine the font codec 10 and the message data to view the text message transmitted by the sender.

Example 2

3 is a structural diagram illustrating a connection state of a text message transmission system in which a font codec is coupled, and FIG. 4 is a flowchart illustrating a flow of a text message transmission method in which a font codec is coupled.

3 and 4, the service method of the present invention will be described.

The user terminals 300 that can exchange text messages are connected to each other through the mobile communication network 200, and the text message transmission system (hereinafter, referred to as a "transmission system") in which a font codec is combined is a mobile communication network or a wireless Internet network. It is connected to each user terminal 300 through.

The transmission system 100 includes an MMS server 102 for displaying and transmitting a text message input from the sender's user terminal 300 to the receiver's user terminal 300.

The MMS server 102 performs a function of transmitting and receiving a text message with a font codec combined as in the present invention together with the transmission and reception of a general text message.

However, the MMS server 102 may not be installed in a separate service system, but may be installed together in a system of a communication company operating the mobile communication network 200.

If the font server 104 does not have a font codec in the sender or receiver user terminal, the font server 104 may transmit and install the font codec. To this end, the font server 104 is preferably connected to the font DB 106 that stores data for a plurality of font codecs.

However, if it is connected to a separate system that generates only data for the font codec, the font DB 106 may not be installed in the transmission system 100.

The billing module 108 is responsible for billing related to downloading font data. To this end, the fee payment module 108 is connected through a network and a payment system of various financial institutions (banks, card companies, payment agencies, etc.). In general, the font data download fee is often a small amount and is convenient to handle with the mobile communication service fee. Therefore, the font data download fee may be summed up when billing the mobile communication fee through an alliance with a telecommunication company.

The text message transmission method using the transmission system 100 is as shown in FIG. 4.

First, the caller starts a message client program in his user terminal 300 and inputs message contents to be transmitted to the input window. (S102) The input message contents are converted into message data and temporarily stored in the user terminal 300 of the sender. Stored.

The sender selects a font to be applied to the message content input by the sender (S104).

The message client program searches whether there is font data in the sender's user terminal 300 (S106). The font data to be searched is data for expressing a font selected by the caller.

If there is no font data in the caller's user terminal 300, it is determined whether to purchase new font data.

When the caller decides to purchase the font data, the caller's user terminal 300 accesses the font server 104 of the transmission system 100 and requests the purchase of the font data.

The font server 104 extracts font data from the font DB 106 and transmits and installs the font data to the sender's user terminal 300 (S112).

The billing module 108 accesses the financial institution system through a separate network (not shown) and withdraws the download fee using the user account information.

Such payment may be made before or after the completion of the download, preferably in partnership with other micropayment systems.

Since a payment method or a payment system for purchasing font data uses the same method as a general online content purchase, a separate description is omitted.

When font data is downloaded from the font server 104 or when font data exists in the sender's user terminal 300, the message client program extracts font data for implementing the font selected by the sender (S114).

The message client program combines the extracted font data and the message data to generate integrated message data in which the font is embedded (S116).

Finally, the MMS server 102 transmits the integrated message data in which the font is embedded to the user terminal 300 of the designated receiver (S118).

Upon receiving the message, the user terminal 300 extracts font data from the integrated message data and reconstructs the message as it was originally (S120).

The receiver's user terminal 300 may store the font data extracted from the received message in a memory or a storage device and use the same to reconstruct a message when a message having the same font arrives in the future.

Meanwhile, the sender may transmit a text message having a specific effect together with the text message displayed in a specific font.

To this end, in addition to the message data and font data, a font animation module that implements separate animation effects is combined together and transmitted to the receiver.

The animation effects may include waves, spins, vortices, squeezes, typewriters, and the like. In addition, various types of animation effects may be implemented.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the above-described technical configuration of the present invention may be embodied by those skilled in the art to which the present invention pertains without changing its technical spirit or essential features of the present invention. It will be appreciated that the present invention may be practiced as. Therefore, the above-described embodiments are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the appended claims rather than the detailed description, and the meaning and scope of the claims and All changes or modifications derived from the equivalent concept should be interpreted as being included in the scope of the present invention.

According to the present invention, the user can send a text message in his or her desired font to the recipient, and the receiver can receive the text message in the font sent by the sender, so that the message can be faithfully delivered to the contents it has and Since it is delivered in its designed state, it is possible to express more emotionally.

In addition, according to the present invention, even when sending a text message to a user using a mobile communication network belonging to another language, there is an effect that can send a text message having a variety of fonts regardless of language.

In addition, according to the present invention, when a new font is produced, it is possible to create a new revenue model by selling text messages to users.
