Currently, most videoconferencing technologies do not keep employees sufficiently engaged during business meetings. Recent studies have shown how extended reality (XR) technologies can help in executing remote meetings in new and possibly better ways. One important factor for meetings in e.g. Virtual Reality (VR) is avatar realism, with the...

We recently developed the Holistic Social Presence Questionnaire (HSPQ) to measure the quality of mediated social communication experiences. Initial research confirmed the content and face validity of the HSPQ. This study investigates the convergent validity and sensitivity of the HSPQ. Participants completed a decision-making task in groups,...

Telemeetings such as audiovisual conferences or virtual meetings play an increasingly important role in our professional and private lives. For that reason, system developers and service providers will strive for an optimal experience for the user, while at the same time optimizing technical and financial resources. This leads to the discipline...

5G promises to offer a single network platform that can be optimized for several vertical industries and applications. It is envisioned that this optimization will be achieved through advanced network orchestration functionalities. Video streaming accounts for the vast majority of mobile traffic, hence optimizing performance and Quality of...

Driven by the growth in mobile phone and tablet ownership, recent years have witnessed an increasing trend towards coordinated media experiences across multiple devices. The quality of experience (QoE) over such new generation applications is dictated by the quality of service (QoS) of underlying networks. Inevitable network delay and bandwidth...

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 reports on the evaluation of the concept of interactive camera-based coaching and training (iCaCoT), which focuses on using interactive video navigation for coaching and training purposes. The iCaCoT concept leverages tiled streaming technology, which allows users to navigate freely through high-resolution video feeds while minimising...

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...

HTTP Adaptive Streaming (HAS) refers to a set of novel streaming services that allow clients to adapt video quality based on current network conditions. Their use of existing HTTP delivery infrastructure makes them perfectly suited for deployment on existing Content Delivery Networks (CDNs). Nevertheless, this leads to some new challenges,...

Effective design of shared mediated spaces, information and connectedness requires theory and practice from a range of disciplines such as found in European projects like Together Anywhere, Together Anytime (TA2) and the EIT ICT Labs Mediating Presence activity. Building on this work we continue to investigate the changes in the European digital...

This paper belongs to a research program started in 2006, dealing with Quality of Experience (QoE) aspects of channel zapping. The program, which has relevance for the broader topics Quality of Service and Next Generation Networks, started with quantifying the QoE expressed as a socalled Mean Opinion Score (MOS) for situations when a black...

Performance modeling of the transport control protocol (TCP) has received a lot of attention over the past few years. The most commonly quoted results are approximate formulas for TCP throughput (Padhye et al. (2000) [1]) and document download times (Cardwell et al. (2000) [2]) which are used for dimensioning of IP networks. However, the...

Quality of Experience (QoE) relates to how users perceive the quality of an application. To capture such a subjective measure, either by subjective tests or via objective tools, is an art on its own. Given the importance of measuring users' satisfaction to service providers, research on QoE took flight in recent years. In this paper we present...

Nowadays various digital television services are available. However, the user of these services experiences longer delays than the traditional analog TV while switching from channel to channel. The digital TV operator usually displays a black screen with the channel number during zapping. However, it could be interesting for the TV viewer, if...

Mobile and wireless communication systems are becoming more and more complex, making understanding the interaction of different technologies on different layers a very difficult task. The introduction of sophisticated techniques on the physical layer that react to changes of the wireless channel on small timescales requires new paradigms for...

In an earlier paper we showed, that perceived quality of channel zapping is related to the perceived quality of download time of web browsing, as suggested by ITU-T Rec.G.1030. We showed this by performing subjective tests resulting in an excellent fit with a 0.99 correlation. This was what we call a lean forward experiment and gave the rule of...
