The Real time / Nonreal time Interactive Web Presention Method and System applicated Multimedia Technology}

The present invention relates to a method and system for real-time / non-real-time mutual web presentation using multimedia technology, and the presenter simultaneously announces to a plurality of clients on the web using multimedia technology and real-time / non-real-time bidirectional communication technology. The present invention relates to a new concept interactive web presentation (IWP) method and system for providing information and consulting in real time and non-real time through a server.

Multimedia technology refers to a technology that simultaneously provides text, voice, and image information to a client.

Real time two-way communication technology refers to a communication technology that exchanges information between clients in real time. For information exchange, a server that mediates this is essential. There is the same.

The first is a real time text communication solution that transmits and receives only text information between clients in real time.

In this technique, when the sending client sends the character information to the server, the server retransmits it to a plurality of receiving clients.

In this method, if the server sends information sequentially to each client, there may be a delay depending on the number of clients connected to the server and the capacity of the network. Therefore, the server communicates with the client to minimize the delay. Thread).

That is, when the sending client sends the character information to the server, it means that the server retransmits the character information to the receiving client in sequence rather than sequentially.

This real time text communication technology enables the sharing of text information between clients, so real time text messaging, N: N text conversation, and real time drawing communication are available. It becomes the foundation technology of Real Time Event Communication.

In addition, since data is exchanged with the server, when the client requests the information from the server, the server can search the database and send it to the requesting client. The user authentication process, various bookmark management, user information management, customer It is also essential for implementing database information transmission and reception.

The second is a real time drawing communication solution for transmitting and receiving graphic data between clients in real time, commonly referred to as a 'real time white board'.

In this technique, when the sending client sends graphic information to the server, the server retransmits it to a plurality of receiving clients.

This method is vectorized to minimize large amounts of graphic data. If the sender client draws a straight line on his monitor, all coordinates and color information constituting the straight line in the screen are sent to the receiving side. Therefore, the network load is huge. Vectorization of graphics is essential.

In other words, the graphic data is converted into text and only the environment where the graphic object is drawn (start and end point coordinates, color, line thickness, etc.) is transmitted to the receiver, and this information is reprocessed into the graphic data on the client of the receiver.

The third is a real time event communication solution in which a client of a sender controls an environment of a client of a receiver.

This technique is an automated way in which the sending client intercepts the events of the receiving client and manipulates the event manipulation as the sending client desires.

The fourth is a real time voice communication solution that transmits and receives voice information between clients in real time.

In order to process voice information in real time, a voice codec and streaming technology are required.

Codec (Compress / Decompress) refers to a technology that compresses for efficient storage of a large amount of voice information data and decompresses it for reproduction.

In order to transmit a large amount of voice data in real time in a network environment such as the Internet, such codec technology is essential.

Fifth is a real time video communication solution for transmitting and receiving video information between clients in real time.

Since image data is also large, image codec and image streaming technology are required to process image information in real time.

Image codec (Codec: Compress / Decompress) refers to a technology that compresses for efficient storage of a large amount of image information data and decompresses for reproduction thereof.

In order to transmit a large amount of image data in real time in a network environment such as the Internet, such codec technology is essential.

However, real-time moving picture streaming has a very large load on the network because the moving picture information is so large despite the excellent compression technology.

Conventional off-line business presentations and product briefing sessions were limited to one-offs because limited spaces, such as hotels and venues, and limited number of people attended at specific times.

In addition, in the marketing and sales activities of a company, salespeople visited their customers from the beginning to the contract stage and after-sales service to carry out sales activities and post-services through consultation.

However, the above-mentioned classic off-line marketing, propaganda, and sales methods of the company did not overcome the constraints of time and space, but also resulted in huge labor and management expenses. There was this.

The present invention was created to solve the above-mentioned problems on the offline, the presenter using a multimedia technology and real-time / non-real-time two-way communication technology to present a plurality of clients (Client) simultaneously to the multiple presentation server (Client) server ( Presentation Server) provides real-time and non-real-time information and counseling system, through on-line marketing activities that overcome time and space constraints and dramatically reducing costs. It aims to provide real-time / non-real-time interactive web presentation method and system using new concept of multimedia technology that can contribute to profit creation and enhance corporate and national competitiveness.

Hereinafter, the present invention will be implemented for each module according to the steps.

The first is the module about membership, which is a task that the presenter and the presenter must go through to participate in the presentation room. Joined members are managed as a database, and are given the authority of the presenter by the administrator. Only those with the authority of the presenter can open a presentation room, and the presenter can listen to the presentation in real time through the opened presentation room, or download the uploaded presentation and play it in a non-real time manner.

Member information stored in the database is used in terms of security, community, and personal information management, the details of which are shown in the table table shown in FIG.

The general membership registration process is implemented by one's own description, but in the case of the present system, presenters can subscribe to unsubscribed presenters instead.

The presenter may register the presenter with the member by entering an ID, name, password, etc. on behalf of the presenter, and may notify this by email or other means of communication. The membership module can be implemented through the web as in a messenger or other community sites, and a detailed work procedure of membership is shown in FIG. 10.

With reference to Figure 10 will be described in detail for the membership registration process of the present invention.

1. Both the presenter and the presenter first register as a presenter by using the messenger program means included in the client computer.

2. The basic identity information is entered into the database.

3. The presenter asks the network administrator for the presenter's authority.

4. The network administrator authorizes the presenter by modifying the database.

5. If authorized by the presenter, presenters can be represented on behalf of the presenter and the information of the surrogate presenter is automatically registered in the presenter's friend information table.

6. After the speaker has signed up for the presentees, the presenter will be notified by email, fax, telephone, official letter, or other means of communication, and notified to the client program described above or to be downloaded from the designated download site. .

Presenters, presenters, and presenters who are represented by the presenter can use the client program downloaded after joining to form a community and open or participate in the presentation room.

On the other hand, in the case of presentations that require an unspecified number of presenters, such as company presentations and public seminars, a specific ID of "Guest" is allowed so that the presenter can participate in the presentation without registering. The presenter can determine whether or not the guest participates when opening the presentation room, and a plurality of presenters can access the present invention system by using the guest ID. Presenters who want to participate as a Guest ID without signing up can download the client program of the present invention system from the designated web site and then participate in the presentation room by entering Guest in the ID field in the logon window of the client program. Presenters connected by Guest ID can use only limited functions such as voice, video, N: N text conversation during real time presentation, and special functions (receive real-time text message, personal information management, etc.) that must use unique ID Can not use it.

Second, as a module related to program download, a program of the system of the present invention is divided into a server program and a client program, the server program is installed and operated by a system administrator, and the client program is distributed by the system administrator. In-house program distribution can be made by email, network sharing, etc., but in the case of the present invention, the presenter may not be a member of the company, so it can be downloaded through a web server. Alternatively, the presenter may forward by email or other means of communication for the convenience of the presenter.

11 is a table describing the configuration program and functions of the system of the present invention.

12 shows a combination of configuration programs of the present system. As shown, the whiteboard server transmits the information to the messenger server, so that the client program on the client side can receive the information of the whiteboard server by requesting the information from the messenger server even if it is not connected to the whiteboard server. . This allows the messenger server to be in charge of the r management function when a large number of whiteboard servers are configured to open multiple presentation rooms.

That is, the client group consisting of the presenter and the presenter can refer to the presentation rooms opened in a plurality of whiteboard servers in the messenger program, and based on this information, a specific presentation room can be accessed. The messenger server sends the whiteboard server IP and the whiteboard server port where the presentation room is opened to the messenger program of the client who wants to access the specific presentation room, and the messenger program receives the information by retransmitting this information to the whiteboard program. Try to connect to a whiteboard server with a seal.

When the whiteboard program successfully accesses the whiteboard server, all real-time information generated in the presentation room is made between the whiteboard server and the whiteboard program, and the functions unique to the messenger program can be controlled in the whiteboard program.

Third, as a module for creating a presentation material, a method of preparing a presentation material by a presenter in the present system may be classified into three methods as shown in the table of FIG. 13.

1. Presentation materials are provided on the web, so you can write them in the form of documents that can be referred to through a browser. The file format that is basically used in the web is an HTML file, which can be referred to by entering only the URL path name of the file in the URL input window of the browser even if the client does not download the file. By saving only the path of file, video file, etc., the client can refer to the file. In addition, technologies such as ASP and CGI, which dynamically reconfigure HTML files and provide them to clients, have recently been used. This technology can be used to apply programming techniques such as web document DB linkage and document security.

The present invention supports all document forms accessible through a browser such as ASP, CGI, and Flash in addition to the HTML form, which is the basic document format of the web. Therefore, the presenter can write the presentation document in HTML, ASP, CGI, or FLASH file according to the presenter's ability or personal taste. The presenter can also use the web's basic image file format, JPG or GIF.

Various recently developed web editors are designed to make it easy for beginners to write HTML files, and all text editors include a function to convert and save HTML files. Presenters can create presentations in HTML files and upload them to the server for use in presentations.

2. The browser embedded in the client program itself of the system of the present invention has a URL input window similarly to a commonly used browser, and the corresponding document can be displayed by inputting a specific document address in the URL input window. This feature can be used as a presentation material by remembering the addresses of various documents found by the presenter through web surfing and instructing the presenters to enter the address during the real-time presentation. In addition, the presenter can use it as a form of reference material by instructing the presenters to enter an address when the presenter prepares the presentation and uploads it to the server.

3. The present invention system provides a document creation program means for the convenience of the presentation data creation and more systematic management of presentation materials. Since this program is not included in the downloaded client program but is mounted on the web, the presenter has the advantage that the presenter can access it through the web wherever the network is available such as home, office, or PC room.

The document writing program allows the presenter to prepare the presentation through the process shown in FIG. 14.

When the presenter accesses the presentation materials, the web server reads the presentation data items stored in the database and outputs them in accordance with the data output form of the document preparation program. Is followed by the process of FIG.

Fourth, as a module for uploading presentation materials, when presentation materials are created by an external program, they should be uploaded for reference in real time presentation and non-real time presentation.

The presenter implements this using the upload program means of the client program, and the upload server program means stores the information of the presentation material uploaded to the database. In case of HTML file, only the path of external reference file such as image file, video file, etc. is saved. To upload this type of file, all files referenced by HTML file must be uploaded together. In addition, if there are a large number of pages that make up the presentation, each must be uploaded after the HTML file. The upload program simplifies this complex upload process and has the ability to store additional information in the database that is required when the presenter wishes to refer to the presentation.

The table table shown in FIG. 15 shows the items of the presentation data information stored in the database by the upload server.

Next, FIG. 16 illustrates a process in which the presenter uploads prewritten presentation materials.

As shown in FIG. 14, the presenter stores the presenter information and the presentation material information by using the upload program means, and when the upload server successfully performs the presentation data file, the presentation data document configuration file, You can store additional information files. The presentation document file refers to a web document file in HTML format written for each page. The presentation document document file refers to a picture file or a moving picture file linked to a web document file. The additional information file of the presentation refers to these files when the presenter prepares a voice file, a moving image file, a whiteboard graphic data file, a presentation environment file, etc. in advance for the presentees participating in the non-real time presentation.

Fifth is a module for opening a presentation room, which is in charge of the whiteboard program means among the client programs of the system of the present invention. The client logged on as the presenter requests the messenger program means to open the presentation room, and the messenger program requests the messenger server again. The messenger server finds the IP and port of the smallest number of whiteboard servers in the plurality of whiteboard servers and transmits them to the messenger program means, and the messenger program means transmits them back to the whiteboard program means. The whiteboard program means that the IP and port of the whiteboard server is delivered to the server after opening the presentation room on the server. The complexity of this procedure is to open the presentation room in the most stable mode when using multiple whiteboard servers. Real-time announcements include real-time N: N text conversations, real-time voice conversations, and real-time video broadcasts. Therefore, if multiple presentation rooms are opened on the whiteboard server, there is a concern that the delay of network delivery will increase. In the present invention, in order to minimize this, a whiteboard server management function is given to the messenger server. Accordingly, when the presentation room is opened, the messenger server passes through the messenger server.

17 shows a combination form of each program for generating a presentation room.

The first step is to create a presentation room in the whiteboard program tool of the client-side program. This request is sent to the messenger program means as it is. The messenger program means waits for a response after resending the presentation room creation request of the whiteboard program means to the messenger server. The messenger server continuously receives the changes of the whiteboard server so that the IP address and port of the whiteboard server with the least number of participants or the smallest number of participants can be known and transmitted to the messenger program means. do. The messenger program means may retransmit this information back to the whiteboard program means, and the whiteboard program means may create a presentation room in the whiteboard server according to the received information.

Sixth is a module about participation in the presentation room. Participation of the presentation room is implemented based on the presentation room information displayed in the messenger program means or the presentation room information displayed in the whiteboard program means. The presentation room information includes the whiteboard server IP where the presentation room is located, the whiteboard server port, the maximum number of people, the current number of people, presenter information, and the password of the room. The information of the presentation room is delivered similarly to the process of creating a presentation room shown in FIG. 17, and a detailed method of participating in the presentation room is shown in FIG. 18. When the messenger program means is connected to the messenger server, the information of the presentation rooms established on the whiteboard server is read, and the information is retransmitted to the whiteboard program means by the messenger program means. If the messenger program means or the whiteboard program means attempts to access the opened room using this information, it will access the opened presentation room.

After the process as shown in FIG. 18, the document is automatically displayed after receiving the presentation data of the presentation room through the database. If the presenter uses the presentation material in the form of using the document on the pre-written site as the presentation material, the presentation information is not transmitted and referred by the presenter by inputting the URL of the presentation material into the URL input box according to the presenter's instructions. can do. 19 illustrates a process of receiving information of a presentation data after joining a presentation room and displaying it on a screen. The presentation information stored in the database is sent to the messenger server, which is sent to the whiteboard program means. Then, the whiteboard program means accesses the web server using the received presentation data information (URL path of the presentation data) and navigates the presentation document.

The seventh module is a presentation progress module. When participating in a live presentation, the presenter and the presenter display the presentation document through an HTML viewer, and display real-time N: N text conversation, N: N voice conversation, and 1: N video information. In addition, N: N whiteboard graphic data is exchanged, and information is exchanged between clients. These functions are all made between the whiteboard server and the whiteboard program means, and after joining the presentation room, the various functions of the messenger program means can still be used.

The presenter sends his or her video to all the presentees through the camera and capture board, and delivers his voice through the microphone. Speakers who are given the right to speak can also pass their voices to other clients through the microphone, while maintaining one to four clients who can speak at the same time. In addition, clients who do not have the right to speak can perform their own communication such as question / answer using N: N text conversation function. The N: N whiteboard graphics feature, on the other hand, allows presenters to mark important notes directly on the presentation document during the presentation and communicate them to the presenter, who can also use the feature to display specific pictures on the web document. Can be. Various events generated by the presenter at the time of presentation, such as switching the presentation document page, scrolling the presentation document, navigating back and forward documents, navigating through the address input window, and navigating to the link page through anchors, are also available. It is sent to the exhibitors under the arbitration of.

20 illustrates a format for transmitting information between the presenter and the presenter during the presentation process.

The whiteboard server transmits the changes to the messenger server in real-time announcement to manage the messenger server, and connects the whiteboard program means and the messenger program means to use the functions of the messenger program means in the whiteboard program means. do. The whiteboard server, which arbitrates all real-time information, transmits voice information, text conversation, and whiteboard graphic information generated between clients such as presenter and presenter in N: N.Only event information and video information generated by the presenter is 1: N. To the presentationees.

Eighth is a module related to presentation material reproduction. In order for the presenter to reproduce the presentation in a non-real time manner, the presenter should log on to the messenger server using the messenger program means and play it by the whiteboard program means. Presenters of Guest accounts who are not registered members can also refer to the presentation materials in a non-real time manner if the presenter permits.

The presenter uses the upload program means to save the presentation document file, the presentation document document configuration file, and additional information file of the presentation on the web server, and store this information in the database via the upload server. In order to refer to this information, the presenter receives the presentation data of the database from the messenger server, and accesses the web server from the information to navigate the presentation data. Among the presentation materials, voice files and moving image files are played without being downloaded by streaming method, and the presentation documents and presentation document configuration files are web documents, so they can be navigated without being downloaded. Whiteboard graphic data files, presentation environment files, etc. are not very large, so users download and play them, and when playing them, voice files and video files are played at the same time, and navigation to web documents performed by the presenter during playback ), Graphics of the whiteboard are also played. Next, the function of each file is shown in a table table shown in FIG. 21, and a process of reproducing it is shown in FIG.

As shown in FIG. 22, the whiteboard program means that has received the presentation data information (received the URL of the presentation data) via the messenger server and the messenger program means downloads the whiteboard graphic data file and the presentation environment file. When the presenter plays the presentation environment file using the playback function in the whiteboard program means, the whiteboard program means navigates the presentation document file using the received presentation data information and displays it through an HTML viewer. Stream and play video files. It also reads the graphic data from the downloaded whiteboard graphic data file and displays it through an HTML viewer, and plays back the events saved by the presenter.

Ninth is a module for the invitation to present, and the presenter can be divided into three ways of presenting the presenter to the presentation room, which is illustrated in FIG.

Hereinafter, a description will be given of how communication technology applying the real-time concept is applied in the present invention.

In the present invention, Winsock 2 is used, and text communication is implemented based on the TCP / IP method, which is widely known as a bidirectional data transmission.

This method provides a reliable, bidirectional, connection-based protocol that uses byte streams, so that it checks each received packet and requests retransmission of lost or corrupted packets. .

In the present invention, a view is managed using a title string that appears in a caption bar of a frame including a view for managing pages.

Therefore, when a client draws a picture on a specific page, the corresponding page information is also transmitted along with the graphic data, and the received client outputs the graphic data only to the designated page.

In addition, for the convenience of drawing, the drawing can be done using the bending line technique. The Bending Line technique means that when a user drags the mouse cursor during drawing, gray lines such as rubber lines are output from the starting point to the current mouse cursor position, and the figure is drawn by the person who draws the picture. It is a technique to make it known. To use this technique, every time you move the mouse, you must delete the previously drawn picture and redraw it at the new coordinates. In the classical method, the screen background before drawing is stored in the temporary storage device and then redrawn when the picture disappears, thereby drawing or deleting the picture. However, the present invention implements this by the XOR output technique.

XOR output method is to output screen background and new picture to draw by using XOR operation. When outputting like this, the color of the picture to be drawn and the color of the background picture are combined with XOR operation and appear as a new color. If you draw a picture with XOR operation again, the original background color is restored and the drawn line is erased.

Therefore, when drawing a completed picture, the picture to be drawn by COPY should be output once more. Although this method has the disadvantage that the color of the bending line technique is different from the original color, it is used in the present invention because of the advantage that the screen restore operation can be performed quickly and the output position of the picture can be known.

In the present invention, when the presenter switches pages of the presentation document or scrolls, the presenter may manually perform the presenter according to the presenter's instructions. However, the presenter intercepts the presenter's event and communicates with the presenter's whiteboard program. Real-Time Text Communication) can be used to automatically perform these event manipulations. This automated approach simplifies the presentation process.

In other words, the event message generated by the presenter and the additional information accompanying the message are transmitted to the presenter's whiteboard program as it is via the server, and the received whiteboard program directly generates the corresponding event. This allows you to control page transitions and scrolling as if they were controlled by the presenter.

In the present invention, the voice codec selects and stores only a human voice among various sound sources heard through a microphone, thereby increasing the compression ratio and maintaining high sound quality.

In addition, the network bandwidth is less than 3kbps of voice information per person, so even on a slow line, there is little risk of packet loss.

The part that streams the voice is in charge of the whiteboard server that mediates the real-time information between the clients and implements 1 to 4 tokens for effective presentation.

All clients must use a Duplex Sound Card to enable two-way voice communication.

If 4 tokens are used, there are 4 speakers, and 4 voice data are compressed on each client and then transmitted to the server. The server retransmits this information to the client in the same room as the speaker, and the clients who received the voice information release the compressed voice information and synthesize the voice information of each speaker through the audio mixer. Output through On the other hand, because it supports Duplex, you can receive voice information from the server even when you speak, and hear other speakers' voices through the speaker.

In the present invention, a real-time moving picture streaming product is installed to build a real-time moving picture transmission system. Moving picture streaming product consists of streaming server, encoder, player or player. It may be.

The presenter should be equipped with a camera and a capture board on the computer to receive his / her moving picture into the computer. The encoder program displays the presenter's video captured in real time in a streaming server program. Board Server). The streaming server program streams video information to clients requesting video in real time, and the player program that receives the video is embedded in a whiteboard program using ActiveX technology.

The present invention accesses a database using ODBC, which is a standard connection technology, to allow access to various database engines operating in a window system. Can be replaced by the techniques listed in the table.

On the other hand, the servers constituting the system of the present invention includes the function of the database server to minimize the transmission delay due to the inter-server interworking that can occur by operating a separate database server.

25 is a connection structure of a server accessing a database in the present invention. As can be seen from the figure, the data of the present invention system is largely divided into two types of member information and presentation data, and the member information data can be inputted and output through a messenger server, and the presentation data is inputted into a database through an upload server. Read through the messenger server.

By applying the above technology, the present invention is able to present and consult to thousands of customers at the same time by realizing the web-based real-time two-way communication program and the whiteboard and database to be able to present and consult at the same time. .

The present invention having the configuration and operation relationship as described above, the presenter using a multimedia technology and real-time / non-real-time two-way communication technology in real time / through a presentation server (Presentation Server) to a plurality of clients (Multiple Client) simultaneously on the web By providing information and consulting in non-real time, the company has been actively contributing to the company's sales growth and profit generation through on-line marketing activities that overcome time and space constraints and significant cost savings. This has a very useful effect of increasing national competitiveness.
