Abstract

PURPOSE: A method for sharing a screen and manufacturing a white board on a network and a servicing method using the same are provided to supply a function capable of being used at all fields requesting an explanation or a common work on a network effectively by performing a white board function independent of the application programs. CONSTITUTION: A screen sharing and white board system(10) performs a function for making a predetermined application program(20) set between two persons to be communicated therewith and contents(41) being inputted from a real time pen input device as a pen mouse be transmitted to the responded person simultaneously on a network, and thus makes a screen(30) be displayed as an overlapped state. Elements of the screen sharing and white board system(10) are described as follows. A module captures an entire screen or a specific application program screen. A module compresses a captured screen for decreasing a transmission amount and decreasing a load of a network. A module transmits compressed screen information to the network as one to multi or multi to multi. A module overlaps and displays functions supplied by a white board on a captured screen. A module processes a movement of an input device as a mouse and transmits the movement to the network. A module overlaps and displays information of a white board received through the network on a screen. A module releases a compression of screen information received through the network. A module displays compression-released screen information on a screen.

Description

Screen sharing and whiteboard production method on network and service method using same {Web page sharing and white board system in on-line and It's server method}

The present invention is a system that combines the function of showing the user's entire screen or application screen on the user at the same time on the network and the independent whiteboard independent of the application program belongs to the Internet communication system and sells as a solution using this system. In addition, it belongs to the Internet business model field, which is a member service on the Internet and earns Internet advertising revenue.

Software having a function similar to the present invention has a function of sharing a common whiteboard and application program of Microsoft Corporation. Since these two functions are currently independent and not mutually interrelated, they cannot basically provide essential functions for an application such as the present invention, and the only way to solve this problem is to provide the application directly. . Therefore, the present invention is a new technology that interconnects these two functions, and in particular, a technology in which a whiteboard function is linked to a shared application is a new technology that has not been attempted yet.

The present invention provides a function of sharing the screen of all applications among the network users, and also can be effectively used in all fields requiring explanation or collaboration on the network by performing the function of the whiteboard independently of the application. Provide functionality.

In order to implement such a function in the present invention, first, a technique for capturing a full screen or a screen of a specific application and compressing the captured screen;

Transmitting compressed screen information to a network;

A technique of superimposing functions provided by the whiteboard on the captured screen;

A technology for processing information by a whiteboard function and transmitting it to a network;

A technique of displaying information of a whiteboard received through a network, superimposed on a screen;

Decompressing the screen information received through the network;

We developed a technology for displaying decompressed screen information on the screen.

1 is a block diagram of a screen sharing and whiteboard manufacturing method and a service method system using the same on a network.

2 is a functional flowchart at the time of network transmission.

3 is a functional flowchart at the time of network reception.

<Description of Symbols for Major Parts of Drawings>

50: Capture entire desktop / application screen

51: Image compression to reduce throughput when transmitting over the network

52: Compressed and sent to the network

60: (pen) accepts mouse input

61: output superimposed on the current screen

62: vectorize mouse input and send over network

70: Receive compressed image from network

71: Decompresses the received compressed image

72: output the canceled image on the current screen

80: Receive drawing information

81: interpret the received information

82: output superimposed on the current screen

The screen sharing and whiteboard system 10 on the network of the present invention is a content input from a real-time pen input device such as pen mouse and any application program 20 set up between two people to communicate on the network as shown in FIG. Simultaneously transmitted to the counterpart and overlapped with each other, the screen 30 is shown.

The screen sharing and whiteboard system 10 on the network of the present invention includes a module 50 for capturing a full screen or a screen of a specific application,

As the module 51 compresses the captured screen, it reduces the amount of transmission, thereby minimizing the load on the network. In addition, the present invention provides a module 52 for transmitting the compressed screen information to the network 1: 1: or:

A module 61 for superimposing functions provided by the whiteboard on the captured screen;

A module 62 for processing information by a whiteboard function for transmitting an input device movement such as a mouse in real time and transmitting it to a network;

Module 82 for displaying the information of the whiteboard received in the network overlapping the screen,

Module 71 for decompressing the screen information received by the network,

And a module 72 for displaying the decompressed screen information on the screen.

As described above, according to the present invention, it is possible to provide a function of a multi-party white board independently to all application programs, and also to share the same screen for all documents of Word and PowerPoint, so that the groupware on the network and the remote Face-to-face effects can be achieved in areas such as education and consulting.
