초록

본 논문에서는 실시간 전송 및 군용환경을 만족하는 소형, 경량 임베디드 영상부 복호화 시스템을 개발하였다. 제안하는 시스템은 ADV212와 FPGA를 기반으로 개발하였다. 본 논문에서는 장치 소형화를 위한 최적 하드웨어 설계방법, 노이즈가 포함된 입력 영상신호에 강인한 소프트웨어 설계방법 등을 제안한다. 실험 결과에서 알 수 있듯이, 본 장치는 국내 기 개발하여 운용중인 DSP를 이용한 Motion JPEG 2000 영상압축장치 이용한 동일 구현방법 보다 6~7배 정도 경량이고, 압축복원시 영상프레임의 지연 시간도 대략 2~3배 이상 빠르다. 군용장치 장비로서의 신뢰도 입증 위해 수행한 환경시험규격(MIL-STD-810G) 및 전자파간섭시험규격(MIL-STD-461F)에서도 규격을 만족함을 입증하였다.

In this paper, we developed a miniaturized real time video compression system satisfying the military environment using ADV212 and FPGA. We present an efficient hardware design scheme for the weight reduction of the device and also a software solution to deal with noisy image signals. Experimental results show that the frame delay is reduced by a factor of 2 or 3 and the device's weight is decreased by a factor of 6 to 7. In order to prove the reliability for the military usage of this development, we examine the environmental test (MIL-STD-810G) and EMI test (MIL-STD-461F). Experimental results show that the developed system satisfies the requirements.
