Few people would purchase a home that does not offer running water, reliable electricity and a road to get there-and increasingly, few would want to live permanently in a home without fast, reliable and affordable internet connectivity. This transition from a valuable, but somewhat secondary, infrastructure to a crucial utility, largely during the last decade, has made researching broadband connectivity ever more relevant. While the United States and other high-income countries have now deployed some kind of internet access to above 90% of households and nearly 100% of young adults access the internet by various means (typically by smartphone), the adoption and availability of key internet applications with societal benefits, such as remote work, telehealth and distance education, remains much lower, particularly for households with lower income and those living in rural areas." A recent Harris Poll 2 commissioned by National 4-H Council and Microsoft found that 21% of teens do not have internet access at home but instead rely on schools, libraries, and other public places to get access.

It uses dynamic rates and coefficients to constantly adapt to local conditions and to allow for provider and application differentiation.

It provides a comprehensive set of terms in order to avoid ambiguities in future IRTF and IETF documents on Network Coding. This document is the product of the Coding for Efficient Network Communications Research Group (NWCRG), and it is in line with the terminology used by the RFCs produced by the Reliable Multicast Transport (RMT) and FEC Framework (FECFRAME) IETF working groups.

The 2nd Convergence: A Technology Viewpoint

The first convergence, the technology convergence, was in fact many convergences: the wired/wireless and fixed/mobile convergence that gave us the Internet of today and ubiquitous connectivity, the device convergence of smart phones and tablets, and the media convergence that changed the way we consume content at home, work and on the road. The 2nd Convergence is melding technology, business models, social networks and culture and catalyses media and story telling innovation. It is breaking through traditional design silos and is displacing traditional linear value chains and some the predominant business models and creates a new generation of innovators, users and creators across skill and age barriers. This book chapter will review the technology convergence, the first convergence, by revisiting its heritage, establishing its basis, reviewing current and past research and providing early implementation examples as well as challenges and controversies. It will show that the 2nd convergence emerges from it and promises even more innovation in the future.
An Implementation of Network Coding with Association Policies in Heterogeneous Networks

Many advances in networking technologies have utilized this change by focusing on the content of an exchange rather than the endpoints exchanging the content. Network coding and informationcentric networking are two examples of these technology trends, each being developed largely independent so far. This paper brings these areas together in an evolutionary as well as explorative setting for a new internetworking architecture. We outline opportunities for applying network coding in a novel and performance-enhancing way that could eventually push forward the case for informationcentric network itself. I.

At the same time, the varying methods of viewing, interacting with, and sharing content have diverged. This paper introduces neXtream, a new approach to delivering video by integrating multiple devices, content sources, and social networks. This concept is developed following research in social television and converged applications, providing both personalization features and social interaction. NeXtream delivers video by dynamically generating streams of video customized to a viewer, while facilitating a common dialog between users around the content, creating both a user- and community-centric viewing experience. NeXtream integrates smartphones, PCs, and TVs to deliver video content to viewers. The paper presents the system concept, theory, and architecture, and describes the developed prototype.

To fulfill this goal, a collaboration was established with the University of Surrey Spacecraft Engineering Unit to test Spar&#39;s compression code on UoSAT-5 EIS images and have it ultimately executed onboard UoSAT-5. Image compression of the UoSAT-5 remote sensing data has been achieved by a number of algorithms including lossy methods such as the `discrete cosine transform&#39; (DCT) related to the JPEG standard, the `block truncation&#39; (BT), the `vector quantization (VQ) as well as lossless compression methods.

Video is now ubiquitous in the home and on the street. It demands new approaches to video transmission to meet the growing traffic volume. This paper presents a novel strategy for network coding in video transmission. It uses a variety of coding approaches and adds feedback and device discovery to tailor the coding to the receiver ecosystems and can achieve better overall performance than the non coded versions 1 .

We propose a simple, distributed, two-stage message passing algorithm to generate network codes for single-source multicast of multi-resolution codes. The goal of this pushback algorithm is to maximize the total rate achieved by all receivers, while guaranteeing decodability of the base layer at each receiver. By conducting pushback and code assignment stages, this algorithm takes advantage of inter-layer as well as intra-layer coding. Numerical simulations show that in terms of total rate achieved, the pushback algorithm outperforms routing and intra-layer coding schemes, even with field sizes as small as 2 10 (10 bits). In addition, the performance gap widens as the number of receivers and the number of nodes in the network increases. We also observe that naïve inter-layer coding schemes may perform worse than intra-layer schemes under certain network conditions.

We are specifically interested in groups based on connections that are established using the emerging online social networking tools like Facebook, MySpace, etc. This paper explores the value chain dynamics resulting from the integration of social networks with a given service. The example we will be using in this paper involves social TV applications, with a focus on social discovery. We hypothesize that these mashup social services introduce new control points in a given service's value chain, which complement or compete with existing control points. The paper focuses on the North American experience.
