As the necessity of software and hardware for the coding of moving picture increases many of moving picture compression techniques are emerged. As a standard, MPEG, one of them, is settled. In this paper, by using Video Overlay Board on PC, MPEG Encoder is implemented. For the purpose of processing per frame-unit, Device driver was made and it is used in the control of VCR in which RS-232C is contained. In order to implement moving picture coding, Video Overlay Board which is used is easy to capture images and to treat them. MPEG encoder is implemented on PC by using software which is composed of C-language and Assembler. Although it cannot be implemented in real-time, we can obtain considerable data compression ratio and moving picture of VCR picture-quality.

교체에 대한 휴지기 측정은 치과질환의 하나인 TMJ 증후군의 진단에 매우 유용한 방법이다. 본 열구에서는 마이크로프로세서를 이용하여 휴지기를 측정함에 있어서 환자의 충신호에 따른 이득조정이 필요없고 실행시간도 빠르며 상격이 보렴하고 사용이 매우 편리한 변과용 의료장비를 설계하였다. 이 장비를 사용하여 휴지기를 측정한 결과 정상인은 20∼30ms이고 환자의 경우 60ms정도이며 실행시간은 0.5 sec이었다. The measurement of the silent period of Masseter muscle is very useful diagnostic method of TMJ syndrome. In this paper, we design a very convenient and very low-priced medical instrument for dental research which does not need gain control to each patient for measuring the silent period and the data processing time is very short. The result of SP measurement using this instrument is 20-30ms in normal subjects and about 60ms in TMJ patient, and the data processing time is 0.5 second.
