Random Linear Network Coding for 5G Mobile Video Delivery
An exponential increase in mobile video delivery will continue with the
demand for higher resolution, multi-view and large-scale multicast video
services. Novel fifth generation (5G) 3GPP New Radio (NR) standard will bring a
number of new opportunities for optimizing video delivery across both 5G core
and radio access networks. One of the promising approaches for video quality
adaptation, throughput enhancement and erasure protection is the use of
packet-level random linear network coding (RLNC). In this review paper, we
discuss the integration of RLNC into the 5G NR standard, building upon the
ideas and opportunities identified in 4G LTE. We explicitly identify and
discuss in detail novel 5G NR features that provide support for RLNC-based
video delivery in 5G, thus pointing out to the promising avenues for future
research.Comment: Invited paper for Special Issue "Network and Rateless Coding for

The VITI program: Final Report
In this report we present our findings and results from the
VITI program in 2000. The focus of the research work undertaken by
VITI has been to provide electronic meeting environments that are easy
to use and afford as natural a collaboration experience as
possible. This final report is structured into three parts. Part one
concerns the VITI infrastructure and consists of two sections. The
first section describes the process of establishing the
infrastructure, concentrating on how the work was done. The second
section presents the actual infrastructure that is in place today,
concentrating on what has been put in place. Part two examines the use
the VITI infrastructure has been put to, giving examples of activities
it has supported and discussing strengths and weaknesses that have
emerged through this use. Finally part three considers the future of
distributed electronic meeting environments. It is recommended that
the report be read in the order in which it is presented. However,
each section has been written as a standalone document and can be read
independently of the others
Mobile support in CSCW applications and groupware development frameworks
Computer Supported Cooperative Work (CSCW) is an established subset of the field of Human Computer Interaction that deals with the how people use computing technology to enhance group interaction and collaboration. Mobile CSCW has emerged as a result of the progression from personal desktop computing to the mobile device platforms that are ubiquitous today.
CSCW aims to not only connect people and facilitate communication through using computers; it aims to provide conceptual models coupled with technology to manage, mediate, and assist collaborative processes. Mobile CSCW research looks to fulfil these aims through the adoption of mobile technology and consideration for the mobile user. Facilitating collaboration using mobile devices brings new challenges. Some of these challenges are inherent to the nature of the device hardware, while others focus on the understanding of how to engineer software to maximize effectiveness for the end-users. This paper reviews seminal and state-of-the-art cooperative software applications and development frameworks, and their support for mobile devices
