Abstract

디지탈 텔레비젼 신호 처리 시스템에 있어서 특정 코드 워드, 패킷 정렬 플래그(PAF)는 픽쳐 그룹(GOP)의 존재를 알리기 위해 MPEG 코드 워드 비트 스트림내에 삽입된다. 상기 PAF는 GOP를 개시하는 "I"프레임용 픽쳐 스타트 코드 워드를 바로 앞선다. PAF가 나타날 때 구성중에 있는 데이타 패킷은 GOP가 패킷 바운더리에서 시작되기 때문에 종료된다. 이러한 종료는 데이타 패킷을 완성하는데 필요한 소정 갯수의 코드 워드 보다 적은 단축된 패킷을 생성시킨다. 각 패킷의 최종 워드는 데이타 패킷과 각각의 헤더를 계속해서 조합시키게 하는 워드로서 표시된다. 소정 갯수의 워드를 갖는 완성된 데이타 패킷을 구성하기 위해 미완성된 데이타 패킷에 널(null)(제로비트)워드가 채워진다.In a digital television signal processing system, a specific code word, packet alignment flag (PAF), is inserted into the MPEG code word bit stream to signal the presence of a picture group (GOP). The PAF immediately precedes the picture start code word for the " I " frame initiating the GOP. When a PAF appears, the data packet in the configuration ends because the GOP starts at the packet boundary. This termination produces shortened packets less than the predetermined number of code words needed to complete the data packet. The last word of each packet is denoted as a word that causes the data packet and each header to continue to be combined. A null (zero bit) word is filled in an incomplete data packet to form a complete data packet with a certain number of words.
