Abstract

The broadcasting of the analog TV was terminated in 2012 and was converted into the broadcasting of the digital TV, so methods for arrival of DAB(Digital Audio Broadcasting) are planned recently. Thus, with digitization of analog broadcasting and appearance of new service, it takes effort to improve efficiency of broadcasting frequency. T-DMB which came in 2005 uses existing analog TV band and its channel is allocated inefficiently in order to avoid interference between mutual services. However, the foundation which can afresh reorganize T-DMB channel is building up because the broadcasting of the analog TV was terminated. So, this paper proposes the method for national SFN composition of T-DMB considering existing local broadcasting in order to provide better service to users as well as improve efficiency of broadcasting frequency.

2012년 아날로그 TV가 종료되고 디지털 TV로의 전환이 이루어졌으며 최근 디지털 라디오의 도입 방안을 수립하기로 하는 등 아날로그 방송의 디지털화와 새로운 서비스의 등장으로 방송 주파수의 효율성을 높이기 위한 노력이 필요하게 되었다. 2005년 도입된 T-DMB는 기존 아날로그 TV 대역을 사용하며 상호 서비스 간 간섭을 피하기 위해 비효율적으로 채널 배치가 되어있다. 하지만 아날로그 TV가 종료되어 새롭게 정비할 수 있는 기반이 마련되었고, 이에 본 논문에서는 방송 주파수 사용의 효율성을 높이고 사용자에게 더 나은 서비스를 제공하기 위해 기존 지역 방송국을 고려하면서 전국 공통 방송을 제공할 수 있는 전국 SFN 구성 방안을 제안한다.
