Abstract

본 발명은 실시간 방송 프로그램의 기준 영상과 부가 영상간의 동기화 방법 및 장치에 관한 것이다. 이러한 본 명세서는 프로그램 레벨의 서술자에 포함되고 기준 영상에 관한 프레임의 시작시간을 지시하는 기준시간 스탬프를 기반으로, 기준 영상의 현재 프레임과 기준시간 스탬프간의 시간차이를 계산하고, 시간차이를 이용하여 기준 영상에 관한 프레임과 부가 영상에 관한 프레임의 동기를 맞추는 동기화 방법을 개시한다. 실시간으로 송출되는 스트림과 함께 동기 시간 정보를 시그널링함으로써, 스테레오스코픽 비디오 서비스가 시작되는 시점의 첫 PMT를 수신하지 못하거나 패킷에러가 발생했을 때에도 저장된 부가 영상과 실시간으로 전송되는 기준 영상간의 동기화가 가능하다. 이로써 안정적으로 스테레오스코픽 영상 서비스를 제공할 수 있다.
