Research Topics

Technologies for Efficiency Networks

Information technology has many applications related to energy efficiency, by means of both communication networks and end user devices (the Internet of Things). Developing intelligent devices, able to monitor energy use in smart homes and cities, and having the ability to access this information from any device (e.g. a smart phone) are two key components in the development of these technologies.

QoS and QoE in 3D video transmission systems

3D video encoding and delivery requires of adecuate QoE assessment methodologies, able to measure how the process of encoding, delivering or adapting the content affects the quality of experience. Moreover, there is a need to evaluate advance encoding schemes required to reduce the bitrate of 3D video streaming services.

Performance evaluation of content distribution mechanisms

The performance of mechanisms related to error correction, scheduling, cache management or content popularity is crucial in the delivery of unidirectional push content delivery services (DVB-T/T2, IPTV) with sufficient quality, regarding download times or the use of residual bandwidth.

QoS and QoE for the video streaming over heterogeneus networks

Video delivery over wireless networks (e.g. Ad-hoc networks), optical networks (e.g. OBS) or over any network without QoS guarantees, can cause a degradation in the QoE perceived by the user. The implementation of mechanisms to guarantee, adapt or improve video transmission can potentially improve the user experience.  

Distributed signal processing over networks

Signal processing algorithms for multimedia applications have been developed to run on a single centralized processor, where all the information arrive to a single point. This research line works on the design of distributed algorithms that work over a network of processors, but that can achieve similar performance to centralized ones.
