Frame accurate media synchronization of heterogeneous media sources in an HBB context
conference paper
Next generation HbbTV applications promise exciting new possibilities with respect to heterogeneous content sources synchronization, like multi-angle picture-in-picture video rendering and . Frame accurate synchronization is required in order to achieve these new possibilities. In this study, as part of the ongoing European FP7 Next Generation Hybrid Broadcast Broadband (Hbb-Next) project, we investigated the use of content agnostic timestamp information for media synchronization. We demonstrate that frame accurate synchronization on a single device can be achieved between local transport streams and a remote MPEG-DASH stream using a customized GStreamer based test bed. In future research, we will extend our test bed for inter device and inter destination synchronization.
