Optical feeder links (OFLs) benefit from the vast amount of bandwidth available in the THz-regime of the electro-magnetic spectrum, and could enable future terabit-per-second satellite systems. This study assesses the end-to-end performance of analog coherent OFLs for digital video broadcasting (DVB) applications, employing phase modulation (PM)...

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...

In traditional video decoding applications, the number of elementary streams that a hardware decoding platform of an end device can decode is determined at runtime by the. Upon request by the application, the decoding platform verifies whether a new decoding instance with an associated requirement in terms of data rate can fit under the current...

Recent developments in key technologies like 5G, Augmented and Virtual Reality (AR/VR) and Tactile Internet result in new possibilities for communication. Particularly, these key digital technologies can enable remote communication and collaboration in remote experiences. In this demo, we work towards 6-degrees of freedom (DoF) photo-realistic...

Searching in digital video data for high-level events, such as a parade or a car accident, is challenging when the query is textual and lacks visual example images or videos. Current research in deep neural networks is highly beneficial for the retrieval of high-level events using visual examples, but without examples it is still hard to (1)...

The continuing growth in the mobile phone arena, particularly in terms of device capabilities and ownership, is having a transformational impact on media consumption. It is now possible to consider orchestrated multistream experiences delivered across many devices, rather than the playback of content from a single device. However, there are...

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...

Multimedia experiences allow us to access other worlds, to live other people's stories, to communicate with or experience alternate realities. Different spaces, times or situations can be entered thanks to multimedia contents and systems, which coexist with our current reality, and are sometimes so vivid and engaging that we feel we are living...

The media industry is currently being pulled in the often-opposing directions of increased realism (high resolution, stereoscopic, large screen) and personalization (selection and control of content, availability on many devices). We investigate the feasibility of an end-to-end format-agnostic approach to support both these trends. In this paper...

There is a group of communication services that use resources from multiple domains in order to deliver their service. Authorization of the end-user is important for such services, because several domains are involved. There are no current solutions for delivering authentication, authorization and accounting (AAA) to multi-domain services. In...
