Dynamic adaptive 3D multi-view video streaming over the internet

Increasing throughput rates and technical developments in video streaming over the Internet offer an attractive solution for the distribution of immersive 3D multi-view. Nevertheless, robustness of video streaming is subject to its utilisation of efficient error resiliency and content aware adaptation techniques. Dynamic network characteristics resulting in frequent congestions may prevent video packets from being delivered in a timely manner. Packet delivery failures may become prominent, degrading 3D immersive video experience significantly. In order to overcome this problem, a novel view recovery technique for 3D free-viewpoint video is introduced to maintain 3D video quality in a cost-effective manner. In this concept, the undelivered (discarded) views as a result of adaptation in the network are recovered with high quality at the receiver side, using Side Information (SI) and the delivered frames of neighbouring views. The proposed adaptive 3D multi-view video streaming scheme is tested using Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard. Tests using the proposed adaptive technique have revealed that the perceptual 3D video quality under adverse network conditions is significantly improved thanks to the utilisation of the extra side information in view recovery.

Interaction with 3D video content

Interaction with 3D video content

One of the main emerging challenges of future multimedia platforms is the development of three-dimensional (3D) display technology, resulting in a plethora of research activities in the video research community focusing on this topic. This emerging technology is capable of bringing a whole new experience to the end user by offering a 3D real immersive feeling experience. However, research towards meaningful user interaction with the real 3D content is still at its early stages.
Having this in mind, the main aim of this research activity is to provide a comprehensive understanding and investigation about how to develop an interactive 3D video platform that delivers intuitive interaction with 3D video content. The key elements of the proposed platform include effective interaction with the content and the design of appropriate UI modality. Moreover, in order to specify the requirement for the designs, a number of studies into the implication of the 3D content delivery mechanism as well as the best user practices are being conducted.
