현재 여러 기관에서 사용하고 있는 방송 시스템은 스튜디오, 방송 장비의 설치 및 확장에 대한 불편함과 비용의 부담, 거리에 따른 방송품질의 저하 등 많은 문제점을 가지고 있다. 이를 해결하기 위한 대안으로 인터넷을 이용한 방송 시스템이 등장하였다. 이는 별도의 시스템 추가 없이 인터넷이 연결되어 있는 장치를 이용하므로 비용절감과 설치의 간편함, 일정한 방송품질을 제공할 수 있다. 그러나 현재 소개되어 있는 인터넷을 이용한 방송 시스템들은 독자적 합의에 의한 호 설정으로서, 시스템 확장과 선택에 대하여 매우 낮은 퍼포먼스를 제공한다. 이를 해결하기 위해 차세대 네트워크 서비스로 각광받고 있는 SIP(Session Initiation protocol)을 이용하여 방송 시스템을 설계 및 구현 하였다.
