초록

본 논문에서는 DTV 방송장치의 대역외발사강도에 대한 국내외 기준을 고찰하였으며, 장비유형별 방사 마스크 요구조건들을 분석하였다. 이를 토대로 DTV 중계기에 적합한 대역외방사특성 기분을 제안하였으며 실험을 통하여 제안된 기술기준의 유용성을 입증하였다. 제안된 기술기준 값을 이용하면 DTV 중계기의 소형화 및 저가화가 가능하며, 향후 디지털 전환에 필요한 방송구역 확대 등에 유용하게 사용될 수 있다.

In this paper, worldwide standards and regulations on in-band/out-of-band emission characteristics of DTV broadcasting equipments are reviewed, and emission mask requirements of several equipment types are analyzed. Out-of-band emission mask draft suitable for DTV repeater is proposed and its usefulness is evaluated and verified in the experiments. Using the proposed standard, small-sized and cost effective DTV repeater can be implemented to broaden DTV broadcasting coverage for digital switchover.
