국내에서도 본격적으로 디지털 방송이 시작되면서 주로 가정에서만 사용되어 오던 TV 의 디지털화로 컴퓨터와 통신에 가전이 결합되면서 새로운 개념의 양방향 멀티미디어시대를 맞이하게 되었다. 디지털 방송은 디지털 기술을 응용해서 음성과 영상뿐만 아니라 부호나 데이터의 형태로 되어 있는 정보를 양방향에서 제어할 수 있는 환경을 제공하여 디지털 방송을 통해 가정에서 TV 를 시청하면서 뉴스 및 일기예보 검색, 프로그램 안내, 온라인 퀴즈, 온라인 쇼핑, 인터넷 메일 검색 등의 각종 데이터들을 검색하는 기능을 제공할 수 있는 데이터 방송을 가능하게 한다. 본 논문에서는 기존의 아날로그 방식에 비해 다채널의 프로그램과 다양한 부가 서비스를 제공하는 ATSC A/65 표준의 PSIP 파서를 구현하고 이를 통해 EPG(Electronic Program Guide)를 구현한다.
