Description

[0001] N-screen based video conference system [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video conferencing system based on an N-screen, and more particularly, to a video conferencing system capable of connecting to a web space at a terminal such as a computer, a tablet PC,

N screen (N-screen) is a network service that can use the same contents as multiple information devices. It is a computing service that can share one content in various digital information devices such as a smart phone, a PC, a smart TV, a tablet PC, ㆍ Network service. N screen technology is a technology that allows users to view one content anytime and anywhere without having to worry about time, place, and digital devices. For example, you can watch movies downloaded from a computer on a TV, watch them on a smartphone in the subway, can see.

Interactive communication is a communication between two or more user terminal devices via a network, and is generally known as chatting or chatting room.

This chat system can be implemented in a general client-server manner and is composed of a plurality of user terminal devices which are clients connected to the server via a network, The server is composed of an interactive system for connecting / relaying / communicating / controlling interactive communication between user terminal devices.

The Internet chat communicates with each other using a client system provided by each chatter after the chatters access a common Internet information network. The Internet chat includes a client system provided by the chatter, a chat program installed in the client system, a keyboard It is common that an Internet chatting is performed by transmitting a text input by a user to a partner via an input device of the user and transmitting the text entered by the partner to a user.

Here, the Internet chat transmits a program in which an algorithm is configured to allow chatting in the service system to each user and the other party, or installs the chat program received by the user in the user's personal computer or wireless communication terminal, According to the setting, the user writes his / her personal information and transmits the personal information to the service system. After the personal information transmitted by the user is stored in the service system, the user is registered as a member and the chat program is used And the user who has been granted the use authority activates the chat program, and at the same time, establishes a chat with the other party who has access to the same chat program.

In addition, chatting is a method in which a user inputs a message to be transmitted to an opponent through an input device such as a keyboard provided in the client system, and information on the entered opponent is converted into information that can be communicated in accordance with the setting items of the chat program In addition, it is common to transmit the chat program to the service system or the chat program of the partner through the Internet connected to the chat program, and to display the chat through the display means provided in the chat program of the partner.

At this time, meeting with the other party through the chat program is accomplished by a user who activates the chat program is connected to a service system that controls a user of the chat program or the chat program, And a chat with one or more opponents of a plurality of opponents according to a user's selective operation has been performed.

Wireless mobile communication technologies have been developed into GSM, GPRS, and WCDMA networks standardized by the 3rd Generation Partnership Projects (3GPP) International Standardization Conference. IS-95A and IS95-B standardized by the 3GPP2 (3rd Generation Partnership Projects 2) CDMA 2000 1x, and CDMA 1x-EVDO networks. Among these wireless mobile communication technologies, in the IMT-2000 network, the synchronous IMT-2000 is referred to as CDMA 2000 1x-EVDO, and the asynchronous IMT-2000 is referred to as WCDMA.

Here, for the video telephony service, the WCDMA network is provided based on the wired circuit network, and the ITU-T H.324 protocol standard is partly changed in accordance with the 3GPP standardization organization to the wireless circuit network and standardized to the 3G-324M protocol standard In the CDMA 2000 1x-EVDO network, the ITU-T H.323 protocol standard used in the wired packet network is used for the wireless packet network without a separate standard in the wireless network.

On the other hand, based on the Session Initiation Protocol (SIP), a video call service integrating a synchronous network and an asynchronous network is provided. Since Web phone provides video call service using existing packet data network, it is inexpensive and is attracting attention as next generation technology because it can create new service by combining with computer technology.

However, since the video communication network is implemented by a different service provider as a sub-network based on a different protocol, a subscriber who subscribes to a video call service provided on a sub-network tries to make a video call to a subscriber subscribed to another sub- There is a problem in that interworking between networks based on different protocols has to be implemented.
