“…For our field trial, we leveraged the tiled adaptive streaming system and mechanisms as presented in [6,17]. These have been previously demonstrated and validated during a live dance performance in Manchester, May 2013, and as a training tool for professional skiers in Schladming, host of the Alpine Skiing World Championship 2013 [7].…”

In conjunction with BBC R&D experiments and demonstrations at the 2014 Commonwealth Games, an explorative field trial was conducted with a live zoomable UHD video system. The unique field trial featured the world's first live tiled streaming of 4K UHD video to end users. During the trial, we studied and evaluated the attractiveness and novelty of an interactive UHD application, and investigated system design aspects of a live UHD tiling system. In this paper, we evaluate the overall perceived quality of experience (QoE) of the application and to what extent the QoE depends on system factors and/or network conditions. We observe that interactive UHDTV is well received by users, but the delivered experience may decrease in presence of low bandwidth availability.

“…The MPD as defined in MPEG DASH can be readily extended with resolution scale and spatial tiling information. Figure 11 shows an instance of the delivery network based on tiled HAS delivery [17] [18]. It incorporates a set functions for the A/V Ingest and A/V Proxy components based on the tiled HAS mechanism, and a regular Content Delivery Network ( CDN) as the A/V Relay.…”

The media industry is currently being pulled in the often-opposing\ud directions of increased realism (high resolution, stereoscopic,\ud large screen) and personalization (selection and control of\ud content, availability on many devices). We investigate the\ud feasibility of an end-to-end format-agnostic approach to support\ud both these trends. In this paper, different aspects of a format-\ud agnostic capture, production, delivery and rendering system are\ud discussed. At the capture stage, the concept of layered scene\ud representation is introduced, including panoramic video and 3D\ud audio capture. At the analysis stage, a virtual director component\ud is discussed that allows for automatic execution of\ud cinematographic principles, using feature tracking and saliency\ud detection. At the delivery stage, resolution-independent\ud audiovisual transport mechanisms for both managed and\ud unmanaged networks are treated. In the rendering stage, a\ud rendering process that includes the manipulation of audiovisual\ud content to match the connected display and loudspeaker properties\ud is introduced. Different parts of the complete system are revisited\ud demonstrating the requirements and the potential of this advanced\ud concept.Peer ReviewedPostprint (published version

“…In particular, related to the walkthrough scenario described in section III, in a followup publication [6], the authors describe the extension of their ideas towards geo-referenced 360°Hypervideo. More details on tiled delivery of omni-directional video can be found in [7], [8] and [10]. A system exploiting depth information for enhanced playback purposes (see section V-C2) is Plenopticon [1], where dynamic adaptive depth of field is applied to a video sequence recorded using a plenoptic Lytro camera.…”

Abstract-This paper describes how optimized streaming strategies, based on MPEG-DASH, can be employed to power a new generation of interactive applications based on immersive video. The latter encompasses ultra-high-resolution, omnidirectional and panoramic video. The goal is to deliver experiences that are made up of multiple videos of short duration, which can be joined at run-time in an order defined through user interactions. Applications of the technology are widespread, ranging from virtual walkthroughs to interactive storytelling, the former of which will be featured in detail. The main technological challenges tackled in this paper are to deliver these experiences in a seamless fashion, at the highest quality level allowed by network conditions and on a wide range of platforms, including the Web. Besides these, the paper focuses on the two-tier software architecture of the proposed framework, as well as a short evaluation to substantiate the validity of the proposed solutions.
