Abstract

PURPOSE: A multi voIP/streaming conference system in Peer to Peer is provided to solve a limit of multi voice, an overload, removing a dubbing effect, and to adopt a voice buffering. CONSTITUTION: A voice switching system is developed in softwares to overcome the limitation of multi voice support by the existing traffic. The load of a server solves overloads of a server using Peer to Peer method. A dubbing effect according to the flow of network resources is removed by synchronizing voice and streaming. The best sound quality is obtained by utilizing voice buffering technique. A soft image is obtained by manufacturing self-protocol.

Description

P to P응용기술을 적용한 다자간 영상 및 음성 동시 작동 화상회의 시스템{Peer to Peer Technology Applied Multi A/V Streaming System}Peer to Peer Technology Applied Multi A / V Streaming System}

기존방식이 서버중계방식으로 인해 음성의 Packet Distribution에 있어 Full Duplex 지원이 한계가 존재하였으며, 이를 해결하기 위해 기존의 자료교환방식에 이용되던 P to P기술을 적용하여 이 문제를 해결하였으며, 이를 위해 Voice switching system을 소프트웨어 적으로 개발하여 수입 대체는 물론 세계시장에 수출한다.Full Duplex support was limited in the packet distribution of voice due to the server relay method. To solve this problem, P to P technology used in the existing data exchange method was applied to solve this problem. We develop voice switching system in software and export to global market as well as import substitution.

본 발명은 기존 서버중계방식으로 인한 한계를 극복하기 위해 기존 자료교환 방식에 적용되던 P to P방식을 응용한 것이다.The present invention is to apply the P to P method applied to the existing data exchange method to overcome the limitations due to the existing server relay method.

첫 번째, Voice switching system을 소프트웨어적으로 개발하여 기존의 트래픽에 의한 Multi Voice 지원의 한계를 극복하며First, the voice switching system is developed in software to overcome the limitations of multi-voice support by existing traffic.

두 번째, P to P방식을 이용함으로 서버의 부하를 분산시켜 사용자의 네트워크를 이용해 Load balancing함으로 서버과부하 문제를 해결하며,Second, by using P to P method, the server load is distributed and load balancing is performed using the user's network to solve the server overload problem.

세 번째, Voice와 Streaming을 동기화 시킴으로 네트워크의 자원의 흐름에 따른 더빙 효과 제거Third, by synchronizing voice and streaming, it eliminates the dubbing effect due to the flow of network resources.

네 번째, Voice Buffering기술을 활용하여 최상의 음질확보Fourth, securing the best sound quality by using voice buffering technology

다섯 번째, 자체 프로토콜을 제작, 부드러운 이미지 구현하는 것이 목적이다.Fifth, the goal is to produce a smooth image by creating its own protocol.

본 발명은 세부분으로 되어있으며The present invention is divided into three parts
