Abstract

In this paper, we design and implement a digital LCD stopwatch function of the remote control. The central controller and LCD stopwatch is implemented based on the clock signal of the crystal oscillator of 8MHz by using ATmega8 processor in the AVR representative series of ATMEL, Communication module basic, ZBS-using the ISM 2.4GHz frequency band at 100. Stopwatch of remote control that has been proposed, it is possible to solve the three problems. First, it is possible to solve the sight deviation between broadcast camera and panelists glance to large LCD stopwatch monitors. Second, it is possible to avoid the trouble of broadcasting cameras cross replacement, Third, it is possible to minimize the inconvenient of the viewer corresponding to the operation of the horizontal movement of the broadcast camera.

본 논문은 원격제어 기능의 디지털 LCD 초시계를 설계하고 구현한다. LCD 초시계와 중앙제어기는 ATMEL의 대표적인 AVR계열 중에서 ATmega8 프로세서를 이용하며 8MHz의 크리스털 발진기의 클록 신호를 바탕으로 구현하였고, 기본 통신모듈은 ZBS-100으로 2.4GHz의 ISM 주파수대역을 이용하였다. 제안한 원격제어 초시계는 세 가지 문제를 해결할 수 있다. 첫째, 중앙에 설치된 대형 LCD 초시계 모니터 주시에 따른 토론자와 방송카메라 간의 시각 편차를 해결할 수 있다. 둘째, 카메라 교차 촬영방식의 번거로움을 피할 수 있으며, 셋째, 공개방송에서 방송카메라의 좌우이동 동작에 따른 시청자의 시야방해를 최소화할 수 있다.
