“…Even more advanced systems exist, adding support for 360 degree video with 3 degrees of freedom (pitch, yaw, roll) [7]. Such systems enable the user to explore the scene with suitable devices, for example using a VR headset.…”

Media is to a large extent consumed on devices that have non-standard aspect ratios, both physically or while rendering content. For example, social media platforms, televisions, tablets, and android devices, most commonly utilise varying aspect ratios of 1, 16:9, 4:3/3:4, 16:9/9:16, respectively. Web pages tend to use responsive design and can therefore have almost any aspect ratio. As current solutions are static, multiple encoded versions of the content must be created to cater for different aspect ratios, increasing workload, storage space requirements and content management complexity. With this in mind, there is a case for client side dynamic aspect ratios that adapt suitably to the user's device to improve their viewing experience based on a common encoded version of the content. In this paper we make the case for a client side dynamic aspect ratio solution, present work on implementation and experimentation, and finally provide some insights into how such a system could be implemented and provided in real world systems. Our solution was tested on content provided by NRK, including both drama series and TV debates.

“…Several newly defined omnidirectional metadata are added in MPD, including Projection Format (PF) descriptor, Region-Wise Packing (RWPK) descriptor, Content Coverage (CC) descriptor, Spherical Region-wise Quality Ranking (SRQR) descriptor, 2D Region-Wise Quality Ranking (2DQR) descriptor, and Fisheye OMnidirectional Video (FOMV) descriptor. OMAF specifies nine media profiles, including three video profiles such as HEVC-based viewport-independent, HEVC-based viewport-dependent, and AVC-based viewportdependent video profiles [278]. OMAF provides a consistent quality to the whole frame regardless of the viewport position for viewport-independent streaming.…”

Omnidirectional or 360 • video is increasingly being used, mostly due to the latest advancements in immersive Virtual Reality (VR) technology. However, its wide adoption is hindered by the higher bandwidth and lower latency requirements than associated with traditional video content delivery. Diverse researchers propose and design solutions that help support an immersive visual experience of 360 • video, primarily when delivered over a dynamic network environment. This paper presents the state-of-the-art on adaptive 360 • video delivery solutions considering end-to-end video streaming in general and then specifically of 360 • video delivery. Current and emerging solutions for adaptive 360 • video streaming, including viewport-independent, viewport-dependent, and tile-based schemes are presented. Next, solutions for network-assisted unicast and multicast streaming of 360 • video content are discussed. Different research challenges for both on-demand and live 360 • video streaming are also analyzed. Several proposed standards and technologies and top international research projects are then presented. We demonstrate the ongoing standardization efforts for 360 • media services that ensure interoperability and immersive media deployment on a massive scale. Finally, the paper concludes with a discussion about future research opportunities enabled by 360 • video.

“…Finally, we present some of the work on network support of omnidirectional video in the context of VR, which is one of the key applications that will be enabled by 5G networks. The Omnidirectional Media Format (OMAF) standard [224] is another specification that can extend DASH or other streaming systems by specifying the spatial nature of video segments. Furthermore, OMAF also specifies some requirements for players, taking another step towards a complete standard specification for omnidirectional streaming.…”

The commercialization of Virtual Reality (VR) headsets has made immersive and 360 • video streaming the subject of intense interest in the industry and research communities. While the basic principles of video streaming are the same, immersive video presents a set of specific challenges that need to be addressed. In this survey, we present the latest developments in the relevant literature on four of the most important ones: (i) omnidirectional video coding and compression, (ii) subjective and objective Quality of Experience (QoE) and the factors that can affect it, (iii) saliency measurement and Field of View (FoV) prediction, and (iv) the adaptive streaming of immersive 360 • videos.The final objective of the survey is to provide an overview of the research on all the elements of an immersive video streaming system, giving the reader an understanding of their interplay and performance.
