본 논문은 국내의 지상파 디지털 방송 표준인 ATSC표준을 이용하여 디지털 방송 시 제공되는 PSIP (ATSC A/65) 정보를 기반으로 한 전자프로그램가이드를 구현하는 시스템을 제안한다. 이 시스템은 PSIP 파서를 이용하여 방송국으로부터 수신된 MPEG-2 트랜스포트 스트림에서 PSIP 정보를 파싱하고, 이를 토대로 전자프로그램가이드에 필요한 정보를 만들어 DTV에서 보여주게 된다. 일반적으로 방송국으로부터 제공되는 PSIP 정보는 프로그램정보를 비롯하여 다양한 형태로 데이터 방송에 응용될 수 있는 정보를 포함할 수 있는데, 본 논문에서는 임베디드 리눅스 기반의 홈서버 시스템에 적용하여 구현하였다.
