Abstract

In this paper, 4K-UHDTV or 8K-UHDTV and UHD-3DTV that the next generation broadcasting implementation and the possibility of direct receiving environment construction is analyzed on the terrestrial broadcasting. Particularly, we investigated the possibility by analyzing the previous and related works with regard to UHDTV transmission by DVB-T2 that is one of the best commercialized transmission mode. In order that the UHDTV broadcasting succeeds once again after completion of digital terrestrial switch over at the end of 2012, the ultra high resolution image transfer is important. However, the direct, the indoor and ubiquitous receiving environment is important in not only TV but also the personal type multimedia terminal in the sense of UHDTV service penetration. Therefore, in this paper, by using SFN and high error-correcting mode in DVB-T2 standard, the efficient frequency utilization and effective reception environment construction is illustrated. Particularly, SFN network constitution by 2 mutually different frequencies including the VHF bandwidth and UHF band, and etc. is shown. And the method that builds the free wireless receive environment by using SFN low power radio repeater and for home use gap filler is proposed. And the effect and frequency amount required are presented, when UHDTV broadcasting use 10MHz bandwidth.

본 논문에서는 지상파방송 무선전송 환경에서 4K-UHDTV 혹은 8K-UHDTV 및 UHD-3DTV 등 차세대방송 구현 및 효과적인 수신환경 구축 가능성을 현재 상용화된 전송방식 중 DVB-T2 기술을 중심으로 제안하였다. 특히, 2012년 완료된 지상파방송 디지털전환에 이어 또다시 UHDTV방송을 위한 차세대방송 투자와 전환의 성공조건으로 초고화질 영상 전송 외에도 TV뿐만 아니라 개인형 멀티미디어 단말기에서도 수신이 가능한 직접수신과 실내수신 및 언제 어디서나 자유로운 수신환경 제공도 매우 중요함을 강조하고 있다. 본 논문에서는 UHDTV방송 구현 시 효율적인 주파수 활용과 효과적인 수신환경 구축방안을 찾는데 목적을 두고 있다. 아울러 DVB-T2 전송방식이 가지고 있는 SFN 기능 및 강력한 수신오류정정 능력을 이용하여 VHF대역과 UHF대역 등 2개의 서로 다른 주파수에 의한 SFN 송출망 구성 방법을 제시하고, SFN 소출력중계기 및 가정용 Gap Filler를 활용한 자유로운 무선수신환경 구축 방안을 제안하고 있다. 그 외 10MHz 폭 채널을 이용한 UHDTV방송 효과와 주파수 소요량을 제시한다.
