Description

A real-time electronic document sharing system running on a computing device equipped with a web browser supporting WebRTC communication

The present invention relates to a real-time electronic document sharing system executed on a computing device equipped with a web browser supporting WebRTC communication, and more particularly, to a computing device used by both presenters and conference participants while conducting an electronic document meeting in real time. can control electronic documents for meetings in , and by storing electronic documents in volatile memory, when the device is restarted, electronic documents do not remain in memory and data leakage can be prevented. It relates to a real-time electronic document sharing system running on a computing device equipped with a web browser that supports WebRTC communication that can compose an electronic document conference screen that is faster and more realistic than an actual download environment.

Due to global environmental problems, the use of electronic documents is increasing to reduce the use of paper and for systematic and safe document management, and the use of electronic document conferences using electronic documents is also increasing. In principle, electronic documents for meetings should not be possessed by outsiders or individuals due to the importance of their contents.

Electronic documents During a meeting, meeting electronic documents are distributed to meeting participants. At this time, for the security of electronic documents, most electronic document sharing systems place electronic documents on a server and virtualize them to allow meeting participants to use their own computing devices. Get the electronic document from the server and use it.

However, when the presenter of the electronic document conference turns over the page of the document in the presenter's terminal when presenting, the pages of the same document displayed on the conference participant's terminal are not synchronized, causing inconvenience. In addition, there is a problem in that meeting participants cannot individually check the previous page of the same document even if they have questions during the meeting.

Meanwhile, Web Real-Time Communication (WebRTC) is an API (Application Programming Interface) designed to communicate with each other without the need to install a separate plug-in or Active-X between web browsers. WebRTC can be used for voice calls, video calls, and peer-to-peer (P2P) file sharing on a web browser. Since WebRTC technology implements real-time communication using only HTML (Hyper Text Markup Language)5 and JavaScript, a separate plug-in for WebRTC communication is not installed in the web browser.

If both the presenter and meeting participants can control the electronic document for the meeting from their computing device while sharing the electronic document between computing devices equipped with a web browser that supports such WebRTC communication, it is possible to hold a meeting with plain paper. As always, you will be able to hold meetings intuitively and conveniently.

As an example, the display control unit 250 displays an electronic conference screen for conference participants that reflects document turning, document enlargement or reduction, or document editing information from another computing device that has opened an electronic document conference through the WebRTC communication unit 220 . print out As another example, the display control unit 250 outputs an electronic conference screen for conference participants reflecting document turning, document enlargement or reduction, or document editing information input from the user of the first computing device.

3 is an exemplary diagram for explaining a real-time electronic document conference procedure executed in a computing device equipped with a web browser supporting WebRTC communication according to the present invention. For convenience of description, the first computing device is referred to as a computing device used by a presenter, and the second computing device is referred to as a computing device used by conference participants.

The first computing device establishes an electronic document conference according to the presenter's operation (S311). Opening an electronic document conference means creating and storing a virtual dome (DOM) in memory by operating a real-time electronic document sharing system, receiving presenter information and meeting electronic document files, and storing them in the virtual dome (DOM) area, and electronic document conference It means a series of processes to create access information for

A user who wants to participate in a meeting drives a real-time electronic document sharing system of a second computing device to create and store a virtualized dome (DOM) in memory (S312) and connects a communication session with the first computing device through WebRTC communication. The second computing device transmits device performance information including network speed and memory virtual space capacity to the first computing device to which the communication session is connected. The device performance information may include screen size, CPU performance, memory capacity, and multimedia format information of the second computing device in addition to network speed and memory virtual space capacity.

In the electronic conference screen for presenters, functions such as document turning, document enlargement, document page selection, retrieval, distribution, screen synchronization, and document conversion are implemented so that users can intuitively use it.

The first computing device converts the electronic document for a meeting into an image (S314). In order to output an electronic conference document file, for example, a presentation file (ppt) on an HTML screen, the presentation file (ppt) must be converted into an image file. Accordingly, the first computing device converts the presenter's electronic conference document into an image file, for example, PDF.

The first computing device encodes the converted conference electronic document image and the user interface (UI) in the form of components by adjusting the encoding value according to the device performance information of the second computing device (S315). For example, the encoding value may be adjusted when the network speed of the second computing device is fast and the memory virtual space capacity is large, and when the network speed is slow and the memory virtual space capacity is small. The first computing device transmits the encoded electronic document image and a user interface (UI) in the form of components to the second computing device.

When a user interface (UI) in the form of an electronic document image for a meeting and a component form encoded from the first computing device is inputted from the first computing device, the second computing device used by the user participating in the electronic document conference updates it to the changed part to the virtualized dome (DOM) After that, the user interface (UI) composed of the encoded electronic document image and component form is decoded (S316).

The second computing device outputs the electronic conference screen for conference participants based on the decoded conference electronic document and a user interface (UI) in the form of components ( S317 ). The second computing device outputs an electronic conference screen for meeting participants reflecting document turning, document enlargement or reduction, or document editing information input from the first computing device that established the electronic document conference. Of course, the user of the second computing device may select, enlarge, or reduce a page to be viewed from among the electronic document for a meeting by using a user interface (UI).
