Abstract

Since starting of terrestrial digital broadcasting in 2001, there has been discussion on introduction of multiple broadcasting services, one of advantages of digital broadcasting. In the mean time, task force on terrestrial multiple channel experimental broadcasting was formed with government organizations, broadcasting companies and household appliance companies in Oct. 2013, and terrestrial multiple channel experimental broadcasting was started between Jan. to April, 2014. Based on this experimental result, EBS started 2HD MMS experimental broadcasting first in Korea on Feb. 11, 2015. This study was carried out in consideration of operation of 2 HD channels in existing 6MHz bandwidth based on MPEG-2 codec with development of compression technology. A study on image quality optimization was carried out and applied to 2HD MMS experimental broadcasting through application experiment of variable bit rate and change according to 1080i and 720p scanning type.

2001년 지상파 디지털방송 시작 이후, 디지털방송의 장점 중 하나인 다채널방송 서비스 도입에 대한 논의가 계속되던 중, 2013년 10월 정부기관, 방송사, 가전사가 참여하는 지상파 다채널 실험방송 추진반이 구성되어 2014년 1월부터 4월 사이에 지상파 다채널 실험방송이 실시되었다. 이 실험방송 결과를 바탕으로 EBS에서는 2015년 2월 11일 국내 최초로 2HD MMS 시험방송을 시작하였다. 본 연구는 압축 기술의 발전으로 기존 6MHz 대역에 2개의 HD 채널을 MPEG-2 코덱기반으로 운영하기 위하여 실시하였다. 1080i 와 720p 주사방식에 따른 변화 및 효율적 데이터 사용을 위한 가변 비트율(Variable Bit Rate) 적용 실험을 통하여 화질 최적화 연구를 실시하고 2HD MMS 시험방송에 적용하였다.
