기존의 T-DMB 표준 문서에서는 T-DMB 기반의 비디오 서비스를 무료 서비스로 규정하여 스크램블링을 수행할 수 없도록 제한 사항을 두고 있다. 그러나, 최근의 T-DMB 수익 구조 개선의 노력과 차세대 T-DMB(AT-DMB) 기술의 등장으로 T-DMB 기반의 유료 비디오 서비스에 대한 관심이 점차 증대되고 있다. 본 논문에서는 유료 서비스 관련 기존 T-DMB 표준 문서들을 분석하여, T-DMB 채널을 통한 유료 비디오 서비스를 제공하기 위한 효율적인 시그날링 및 스크램블 방법을 제안한다. 제안된 방법은 기존의 비디오 서비스와 역호환성을 유지하여 이미 보급된 T-DMB 수신 단말에 문제점을 야기하지 않는 것을 특징으로 한다.
