A Synchronization and T-STD Model for 3D Video Distribution and Consumption over Hybrid Network

Abstract

SUMMARYRecently, standard organizations of ATSC, DVB and TTA have been working to design various immersive media broadcasting services such as the hybrid network-based 3D video, UHD video and multiple views. This letter focuses on providing a new synchronization and transport system target decoder (T-STD) model of 3D video distribution based on heterogeneous transmission protocol in a hybrid network environment, where a broadcasting network and broadband (IP) network are combined. On the basis of the experimental results, the proposed technology has been proved to be successfully used as a core element for synchronization and T-STD model in a hybrid network-based 3D broadcasting. It has been also found out that it could be used as a base technique for various IP associated hybrid broadcasting services.

Design of Synchronization and T-STD Model for 3DTV Service over Hybrid Networks

“…Because 3D video streams are transmitted over hybrid networks, the PTS of such streams may be different. Therefore, it is necessary to provide a timeline synchronization scheme at the frame level for a robust 3D presentation [20], [21]. This paper proposes metadata-based timeline synchronization that fully resolves the problems described in Section II.…”
