Light field visualization has progressed and developed significantly in the past years. At the time of this paper, light field displays are utilized in the industry and they are commercially available as well. Although their appearance on the consumer market is approaching, many potential applications of light field technology have not yet been addressed, such as video streaming. In this paper, we present our research on the dynamic adaptive streaming of light field video. In order to evaluate the presented concept of quality switching, we carried out a series of subjective tests, where test participants were shown light field videos containing stallings and switches in spatial and angular resolution.

Efficient traffic control and management is a fundamental and urgent challenge in our ever-growing cities. Maximizing roadway capacity usage, balancing traffic flows, decreasing emission, improving traffic safety and providing motorists with the best end-to-end transportation experience are the most important goals of modern intelligent traffic control infrastructures. Evolving traffic light or traffic signal controller systems are playing an important role in these architectures by adaptively and dynamically coordinating individual traffic lights to achieve city-wide objectives of traffic operations. The integration of such systems with vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communication techniques (together referred as V2X) could easily be the next step of this evolution allowing for dynamic real-time information exchange between all the players of the traffic controlling ecosystem and fostering cooperative urban mobility. In this paper we propose a possible architecture for a V2X-integrated traffic light controller systems and present the testbed with our proof-of-concept implementation of the proposed scheme.

Light field displays provide a natural sense of 3D visual experience through the glasses-free visualization of the content. It is enabled by the smoothness of the horizontal motion parallax, which is determined by the density of source images allocated to a given field of view. This measure is commonly known as angular resolution, and similarly to spatial resolution, has a fundamental effect on the visual experience. In this paper, we investigate how the reduction of angular and spatial resolution affect each other. Our hypothesis is that lowering spatial resolution to a certain extent does not degrade the perception of the parallax effect, in fact, it may improve it. We carried out a series of subjective tests on a real light field display to test this hypothesis, results of which are introduced in this paper.

The host identity protocol (HIP) is a rather new concept that separates the identity and location information both represented by IP addresses in the current Internet architecture. HIP also has capabilities and efficient extensions to serve macromobility, but it shows unnecessary signaling overhead and handoff latency, when used in micromobility environments. This paper introduces a new method how HIP can be extended to serve as a micromobility protocol

The scientific researches performed in the past decade clearly highlighted that Quality of Experience (QoE) has become the ultimate measure of service value in this rapidly developing era of technology. Its continuous monitoring is now simply essential and is the key to service success. Subjectively measured QoE is considered to be somewhat unerring, however, several human factors may introduce distortions in the assessment of multimedia quality. Motivated by the phenomenon of cognitive bias, this paper attends the topic of end-user devices; how they may influence evaluation of video streaming quality. We performed an empirical analysis of mobile streaming multimedia quality with 100 participants, and utilized four different subjective measurement scales. Results show that the perception of streaming quality was significantly affected by the phenomenon through cognitive dissonance.
