단지점간 통신 단말기를 이용한 다자간 화상회의 참가방법How to Participate in Multi-party Video Conferencing Using Point-to-Point Communication Terminal

본 발명은 단지점간 통신 단말기를 이용한 다자간 화상회의 참가방법에 관한 것으로, 특히 단지점간 통신만을 지원하는 단말기를 이용하여 다자간 화상회의에 참가중인 다지점간 통신 단말기의 매체(화상, 소리등)를 선택함으로써 다자간 화상회의에 참가할 수 있는 단지점간 통신 단말기를 이용한 다자간 화상회의 참가방법에 관한 것이다.The present invention relates to a method of participating in a multi-party video conference using a point-to-point communication terminal, and in particular, selecting a medium (picture, sound, etc.) of a multi-point communication terminal participating in a multipoint video conference using a terminal supporting only point-to-point communication. The present invention relates to a multi-party video conference participation method using a point-to-point communication terminal capable of participating in a multi-party video conference.

최근들어, 인터넷의 보급과 고속화에 힘입어 수많은 응용 프로그램들이 개발되고 있다. 그 중에 패킷망(packet network)에서의 단지점간 화상회의 단말기는 상호 호환성을 위해 아이티유(international telecommunication union : 이하, ITU)의 H-323 규약에 따라 제조되고 있다. 이와같이 H-323 규약을 지원하는 시판 제품으로는 마이크로소프트사의 넷미팅, 인텔사의 인텔 인터넷 비디오 폰 및 엘지전자의 비쥬얼 링크 300등이 있다.In recent years, a number of application programs have been developed due to the spread and speed of the Internet. Among them, point-to-point video conferencing terminals in a packet network are manufactured according to H-323 protocol of ITU (international telecommunication union) for mutual compatibility. Commercially available products that support the H-323 specification include Microsoft's NetMeeting, Intel's Intel Internet Video Phone, and LG's Visual Link 300.

일반적으로, 다자간 화상회의는 중앙집중 방식, 분산 방식 및 두가지의 혼합 방식으로 구분되며, 중앙집중 방식이 주로 사용되고 있다. 이와같은 중앙집중 방식의 다자간 화상회의 시스템은 다자간 회의장치(multipoint conference unit : MPU)를 사용하는데, ITU는 종합 디지털 통신 서비스망(integrated services digital network : ISDN)을 위한 다자간 회의장치의 규약으로 H-231을 두고 있다.In general, multi-party video conferencing is divided into a centralized method, a distributed method, and a mixed method of two types, and a centralized method is mainly used. This centralized multi-party video conferencing system uses a multipoint conference unit (MPU). ITU is a protocol for multi-party conference devices for integrated services digital network (ISDN). 231.

상기 다자간 회의장치는 다자간 회의 제어기(multipoint conference controller : MCC)를 통해 다수의 다지점간 통신 단말기를 동시에 처리하고, 각 다지점간 통신 단말기로부터 입력되는 매체를 다른 단말기로 분배한다.The multi-party conference apparatus simultaneously processes a plurality of multi-point communication terminals through a multipoint conference controller (MCC), and distributes media input from each multi-point communication terminal to other terminals.

상기 매체를 분배하는 방식은 다자간 회의장치가 각 다지점간 통신 단말기로부터 입력되는 화상이나 소리등의 매체를 혼합하여 다른 단말기로 출력하는 방식과, 각 다지점간 통신 단말기가 원하는 단말기를 다자간 회의장치를 통해 선택하고, 그 선택한 단말기로부터 화상이나 소리등의 매체를 받아오는 방식이 있다.The method of distributing the media includes a method in which a multi-party conference apparatus mixes media such as an image or sound input from each multi-point communication terminal and outputs it to another terminal, and a multi-party conference apparatus desired by the multi-point communication terminal. There is a method of selecting through and receiving a medium such as an image or sound from the selected terminal.

이때, 소리의 경우는 상기 전자의 방식이 주로 사용되고, 화상의 경우는 후자의 방식이 주로 사용된다.In this case, the former method is mainly used for sound, and the latter method is mainly used for images.

이와같은 중앙집중식 다자간 화상회의 시스템은 도1의 예시도에 도시한 바와같이 다자간 회의장치(4)가 각 다지점간 통신 단말기(1,2,3)와의 매체 송수신을 제어하도록 구성된다.Such a centralized multi-party video conferencing system is configured such that the multi-party conference apparatus 4 controls media transmission and reception with each multi-point communication terminal 1, 2, 3, as shown in the exemplary diagram of FIG.

그러나, 상기한 바와같은 종래의 중앙집중식 다자간 화상회의 시스템은 다자간 회의장치가 각 단말기에 다른 단말기의 선택방법만을 제공하는 경우에 단지점간 통신만을 지원하는 단말기를 통해 화상회의에 참가하려고 할 때, 그 단지점간 통신 단말기가 다른 단말기를 선택할 수 없게 되므로, 다자간 화상회의에 참가하는 단말기는 다자간 통신을 지원해야만 하는 문제점이 있었다.However, in the conventional centralized multi-party video conferencing system as described above, when the multi-party conference apparatus provides each terminal with only a method of selecting other terminals, it attempts to join the video conference through a terminal supporting only point-to-point communication. Since only the point-to-point communication terminal cannot select another terminal, the terminal participating in the multi-party video conferencing has a problem in that it must support multi-party communication.

본 발명은 상기한 바와같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 본 발명의 목적은 중앙집중식 다자간 화상회의 시스템에서 단지점간 통신 단말기를 통해 다른 단말기를 선택할 수 있는 단지점간 통신 단말기를 이용한 다자간 화상회의 참가방법을 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems as described above, and an object of the present invention is a multi-party image using a point-to-point communication terminal that can select another terminal through a point-to-point communication terminal in a centralized multi-party video conferencing system. To provide a way to participate in a meeting.
