Abstract

Currently, The terrestrial MMS(Multi Mode Service) is considering to be adapted in the Korea. The objective and subjective video quality test was carried out to verify the current TV channel's video quality degradation by the MMS. In the objective assessment, MMS system showed better PSNR than current system. In the subjective assesment result, It's hard to find the perceive video quality degradation at overall assesment. Even though, The MMS's video quality will be improved at the documentary and entertainment genre. Comparing with the previous research at 2006 and 2008, It's the time to give the benefit of broadcasting technology to the people.

최근 국내 지상파 다채널 방송의 도입이 재 논의되고 있다. 본 연구에서는 지상파 다채널방송 도입으로 기존 방송 채널의 화질 열화에 대해 객관적 화질평가와 주관적 화질 평가를 통해 검증하였다. 객관적 화질 평가에서는 다채널 방송용 시스템이 기존 방송보다 높은 PSNR을 보였다. 주관적 화질평가 결과도 MMS 시스템의 화질 열화를 인지하기 어려운 것으로 나타났다. 특히 시사 다큐멘터리와 연예 오락 분야에서는 다채널 방송에서 화질이 더 개선될 것으로 나타나고 있다. 따라서 2006년과 2008년 연구 결과와 비교할 때, 방송 기술의 발전으로 다채널 방송 도입에 따른 화질열화 우려가 해소됨에 따라 다채널 서비스 도입에 필요한 정책마련이 시급히 요구된다.
