Abstract

PURPOSE: A method for transmitting multimedia messages is provided to divide received messages by four kinds such as a video, an audio, a text, and an image in real time to store the four kinds in a database, and to decide connected terminals by an automatic detection process to synchronize the messages in the terminals, so as to store/transmit various kinds of messages through various terminals. CONSTITUTION: Multimedia messages transmitted by a user are checked whether the messages are normally transmitted. The messages are decided whether the messages are normal. If so, the messages are stored in a temporary database. The messages are divided by four kinds such as a video, an audio, a text, and an image, and the divided messages are stored in a database. If the messages are not normally transmitted, a notice that the messages are not normally received is transmitted to the user through an error process. The multimedia messages are decided whether the messages are normally divided. If so, the messages stored in the temporary database are deleted. The divided messages are synchronized by using motion picture experts group(MPEG) according to terminal kinds. The messages are checked whether the messages are normally synchronized. If so, the synchronized messages are transmitted to connected terminals. If the messages are not normally divided, the process of dividing the messages is repeated.

Description

Multimedia Messaging System and the Method

As shown in Fig. 2, the existing mail system includes a post office protocol (POP) 2_2 and a mail transmission function that serve to receive messages from the host 2_4 that holds messages by the mail program of the user computer 2_1. It consists of two Simple Mail Transfer Protocol (SMTP) servers. An information service provider (ISP) mail server keeps a letter that arrives at the user and delivers the letter to the user's computer when the user requests it. In addition, when a user writes a letter, it receives a message from a mail server and delivers it to another information provider's (ISP) mail server. In general, the current messaging system provides a limited service focusing on text or voice, and even a company that provides multimedia messaging service does not exceed a range of services in which pictures or music are attached to the background of messages. In addition, important information may not be provided in places that cannot support the Internet or communication, which may interfere with not only the business but also the individual's work or activities. The limited use of resources and the limited use of terminals in these messaging systems result in the inability to use a variety of information, which can lead to the inability to satisfy users with a variety of information. Unified Messaging System (UMS) In addition, it is a system that has been recently developed to pursue the convenience of the user beyond the limitation of the terminal of the general messaging system. However, this system also has a wider range of devices than computer-based general messaging systems such as computers, faxes, and telephones, but it does not support a variety of handsets. Moreover, it supports only voice and text, so video, audio, text, images and It does not support the same multimedia message format.

SUMMARY OF THE INVENTION An object of the present invention is to provide a new concept of multimedia messaging system and method that overcomes limitations on the terminal using the messaging system and accommodates all currently provided media formats (video, audio, text, and image). . That is, the purpose is to store and transmit messages in various formats through various terminals, and the present invention also analyzes the protocol for each terminal, so that even if a new terminal other than the existing terminal is developed, the characteristics of the new terminal can be grasped to determine the protocol of the new terminal. The user can transmit and receive a multimedia message without a separate work step even in a newly developed terminal.

With reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

The present invention divides the database into four types of video, audio, text, and image using MPEG, which is a video compression and decompression technology, and a temporary storage database for temporarily storing the received multimedia as shown in FIG. A message partitioning process (i) stored in the network, a terminal automatic discrimination process (i) for discriminating terminals connected via an internet network and a wired / wireless telephone network, and a divided message database storing messages divided by the message splitting process ( I) and a message synthesizing process for synthesizing and transmitting the divided messages according to the determined terminal type.

In the first step 1_1, various multimedia messages sent by the sender are stored in a temporary database, and in the second step 1_2, video, audio and text are received in real time using MPEG, a video compression and decompression technology. In the third step (1_3), the divided message is stored in the divided message database (㉱), and then the database (㉮) in which the original message is stored is deleted. 1_4) determines the connected terminal by the terminal automatic discrimination process (i), and transmits the determined terminal information to the divided message database (i) in the fifth step (1_5), and in the sixth stage (1_6) system The split message is synthesized by using MPEG, which is a video compression and decompression technology according to the terminal information transmitted in step 5 (㉲), and in step 7 (1_7), the synthesized message is converted into an access terminal. The song.

3 is a flowchart of a process of a terminal automatic detection process according to the present invention.

When the user connects through the internet network and the wired / wireless telephone network, it checks whether the terminal is connected (3_2). For example, in the case of wireless internet access using a mobile phone, the user connects using the http method. For example, in the case of a wired telephone network connection using a fax, for example, a fax is connected by using a feature of signaling a response request sent from the receiver side in a telephone connection, that is, hook off state. Check the status of the terminal. After checking the connection status of the terminal (3_2), it is determined whether the terminal connection status is normal (3_3: Q1), and if the connection status is normal (Y), the log file, data format, and header file are received from the connected terminal. Receive (3_5). If the connection status is abnormal, an error message is output (3_4) to induce the user to reconnect. Once the log file, data format, and header file are successfully received, the validity of the received file is verified. If it is determined that the file received from the terminal is valid or inaccurate (3_7: Q2), an error processing process for determining whether an internal error or the received file is unsafe is performed (3_8). Through the process, the multimedia messaging system operates its own internal security function, and the function of analyzing the characteristics of the connected terminal is significantly reduced as the operating time of the multimedia messaging system increases. After checking the validity of (3_6), received log file and data format and header Analyze the protocol of the connected terminal by analyzing the file (3_9). For example, a log file, a data format, and a header file include various information such as the access method, reception speed, memory size, display area, and frequency band of the connected terminal. As it is included, the process of analyzing the protocol of each access terminal is performed by using such data.After performing the protocol analysis process (3_9), the process of extracting the code of the client terminal based on the analyzed protocol is performed. (3_10).

For example, the analyzed terminal-specific protocol includes a client code for identifying an access terminal such as 01 for a computer, 02 for a PCS, 03 for a cellular phone, 04 for a PDA, 11 for a wired connection, and 12 for a wireless connection. Since information on the resources of the terminal for each client code is included, the type and characteristics of the terminal are determined from the analyzed protocol. It is determined whether the client code extraction is normally performed (3_11: Q3). If normal (Y), the type and characteristic of the terminal are determined from the extracted client code (3_12), and the step of FIG. 3 ends.

4 is a flowchart of a multimedia message processing and transmission / reception of the present invention. After checking whether the multimedia message sent by the user has been correctly received (4_2), it is determined whether the received message is normal (4_3: Q1), and if the message is normal (Y), the received message is stored in a temporary database (4_5). .

If the message is not received normally, an error handling process sends a notification to the sender that the message was not received (4_4). After storing the received multimedia message in a temporary database (4_5), the video compression and restoration technology A message segmentation process 4_6 is performed in which the received message is divided into four types of video, audio, text, and image and stored in a database using MPEG. It is determined whether the multimedia message is divided normally (4_7: Q2), and if it is normal (Y), the message stored in the temporary database is deleted to secure the space of the database (4_8). If the message is not normally divided (4_7: Q2), the process of dividing the received message is performed again (4_6). After deleting the original multimedia message from the temporary database, the divided message is synthesized using MPEG, which is a video compression and decompression technique, according to the type of the terminal determined in the step of FIG. 3 (4_9). After the process of synthesizing the multimedia message according to the type of the terminal, it is determined whether the message is normally synthesized (4_10), and if it is normal (Y), the synthesized message is transmitted to the connected terminal (4_11), and the steps of FIG. Ends.

As described above, the present invention, by maximizing the resources of the client (Client) device having a performance limit, escapes the limited service of the existing messaging system, multimedia message without limitation of the terminal and media type and time and place It aims to provide a multimedia messaging system and method that can provide related services, and the expected effects are as follows.

First, by providing users with a means of communication that is not tied to the category of the terminal, it becomes a foundation for providing speed and accuracy of work among employees in the enterprise, and can remove unnecessary elements of work. In addition, since the general user is provided with a more comprehensive multimedia service, it is possible to receive a variety of in-depth contents services, thereby contributing to the change to an active Internet business.

Second, it is expected to create added value through diversification of business through entry into a new concept e-commerce market, and it is possible to secure new technologies through acquisition and application of multimedia processing-related technologies, thereby transferring relevant company technologies.
