As the internet network is growing up, it is possible to transmit the large capacity file such as high-quality stereoscopic 3D content. Thus, the burden of internet network is becoming heavier than before, since 3D stereoscopic video services require larger and more stable bandwidth. Also, it may cause disconnection of the streaming service to provide the large capacity content in the limited network environment. Therefore, it is necessary to develop the technology of streaming service adaptive to the network environment. In order to achieve a seamless video streaming service, the international standardization organization MPEG (Moving Pictures Experts Group) has developed an adaptive HTTP streaming technology called DASH (Dynamic Adaptive Streaming over HTTP). However, the DASH does not have an obvious scheme that can express the two elementary video stream based on the service-compatible stereoscopic contents in a single Segment sequence. Therefore, in this paper, we propose a method of efficient 3D adaptive streaming service based on the DASH, which covers service-compatible stereoscopic content in a single Segment sequence. The 3D adaptive HTTP streaming method introduced in this paper is able to provide seamless streaming service for various kinds of stereoscopic contents.
