Fixed viewport applications for omnidirectional video content Combining traditional and 360 video for immersive experiences

With omnidirectional videos, the viewer is able to direct her Field-of-View (FoV) to any part of the scene while watching the content. This is achieved by rendering the 360 video content on the inside of a (conceptual) sphere in which the viewer is typically placed at the center. This is in contrast with traditional video that is rendered on a...

360-degree video streaming with MPEG-DASH

Virtual reality (VR) has gained a lot of attention due to market availability of consumer devices. A challenge for wider use is the ability to stream VR content to the user. This paper looks at aspects of 360° video streaming and the considerations for possible solutions. The primary focus lies on current efforts to develop standards for...

Media Orchestration between Streams and Devices via New MPEG Timed Metadata

The proliferation of new capabilities in affordable smart devices capable of capturing, processing, and rendering audiovisual media content triggers a need for coordination and orchestration between these devices and their capabilities and of the content flowing from and to such devices. The upcoming Moving Picture Experts Group (MPEG) Media...

MPEG DASH SRD: Spatial Relationship Description

This paper presents the Spatial Representation Description (SRD)feature of the second amendment of MPEG DASH standard part 1, 23009-1:2014 [1]. SRD is an approach for streaming only spatial sub-parts of a video to display devices, in combination with the form of adaptive multi-rate streaming that is intrinsically supported by MPEG DASH. The SRD...

iXperience: A Mobile Application for an Interactive UHDTV Experience

Using MPEG DASH SRD for zoomable and navigable video

This paper presents a video streaming client implementation that makes use of the Spatial Relationship Description (SRD) feature of the MPEG-DASH standard, to provide a zoomable and navigable video to an end user. SRD allows a video streaming client to request spatial subparts of a particular video stream, which might be available in multiple...

Interactive UHDTV at the Commonwealth Games - An Explorative Evaluation

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...

Requirements for multimedia metadata schemes in surveillance applications for security

Surveillance for security requires communication between systems and humans, involves behavioural and multimedia research, and demands an objective benchmarking for the performance of system components.Metadata representation schemes are extremely important to facilitate (system) interoperability and to define ground truth annotations for...

A Hybrid Architecture for Delivery of Panoramic Video

The media industry is being pulled in the often-opposing directions of increased realism (high resolution, stereoscopic, large screen) and personalisation (selection and control of content, availability on many devices). Within the EU FP7 project FascinatE, a capture, production and delivery system capable of allowing end-users to interactively...

Video content representation on tiny devices

The perceptual satisfaction of a user watching video on a tiny mobile device is constrained by the display capability and network bandwidth. To maximize the user's perceptual satisfaction in this constrained environment, we propose a new method to adaptively represent the video content in real-time on tiny devices according to the user's...
