Abstract

Recently an extension to DMB AF (Digital Multimedia Broadcasting Application Format) standard has been proposed in such a way that the extended DMB AF can include stereoscopic video and stereoscopic images for interactive service data, i.e., MPEG-4 BIFS (Binary Format for Scene) data, in addition to the existing 2D video and 2D images for BIFS services. In this paper we developed a service that provides the streaming of 3D contents in DMB AF by using MPEG-DASH (Dynamic Adaptive Streaming over HTTP) standard and validated it by implementing the client software.

지상파 DMB 콘텐츠를 위한 국제 표준 파일 포맷인 DMB AF(Digital Multimedia Broadcasting Application Format) 표준을 확장하여 2D 비디오와 2D 대화형 서비스 데이터, 즉 MPEG-4 BIFS(Binary Format for Scene) 데이터뿐만 아니라 스테레오스코픽 비디오와 스테레오스코픽 BIFS 데이터를 함께 담아 2D/3D 비디오 및 2D/3D BIFS 프레젠테이션이 시간적으로 혼용될 수 있게 하는 방식이 최근 제안된 바 있다. 본 논문에서는 이렇게 확장된 DMB AF 형식의 파일로 주어진 3D 콘텐츠를 MPEG-DASH(Dynamic Adaptive Streaming over HTTP) 표준을 이용하여 스트리밍하는 서비스를 개발하고 이에 해당하는 클라이언트 소프트웨어를 구현하여 이 서비스를 검증하였다.
