The Internet as a video distribution medium has seen a tremendous growth in recent years. Currently, the transmission of major live events and TV channels over the Internet can easily reach hundreds or millions of users trying to receive the same content using very distinct receiver terminals, placing both scalability and heterogeneity challenges to content and network providers. In private and well-managed Internet Protocol (IP) networks these types of distributions are supported by specially designed architectures, complemented with IP Multicast protocols and Quality of Service (QoS) solutions. However, the Best-Effort and Unicast nature of the Internet requires the introduction of a new set of protocols and related architectures to support the distribution of these contents. In the field of file and non-real time content distributions this has led to the creation and development of several Peer-to-Peer protocols that have experienced great success in recent years. This chapter presents the current research and developments in Peer-to-Peer video streaming over the Internet. A special focus is made on peer protocols, associated architectures and video coding techniques. The authors also review and describe current Peer-to-Peer streaming solutions.

Peer To Peer Network

Assuming that video streaming is now responsible for the absolute majority of the Internet traffic and considering that the audience uses WebRTC-enabled web browsers and mobile devices to access and retrieve content, this work proposes the development of a peer-to-peer overlay network to assist the delivery of video streaming events that use HTTP-based protocols without the need to install additional software. Using the peer-to-peer network, the client/server model becomes hybrid, where network nodes that are watching the same event can retrieve portions of the video content directly from the server or neighboring nodes. This approach has two main objectives; decrease the client/server traffic and consequently the economic cost of delivery while improving the quality of the users' experience, given that communication between neighboring nodes can support the flow of better quality videos between the points

The Impact

Today’s Internet knows no bounds. New applications are marketed every single day. Many of them incorporate video sequences. These must be transported over the Internet quickly (often in real time). However, the Internet has not been designed for live communications and, regrettably, this may become apparent all too quickly. Countermeasures are required in the form of new, efficient transport techniques facilitating online video services. MPEG-DASH is one of such modern techniques. But how good is this new technique really? This paper delves into the matter. The paper contains an analysis of the impact that the new technology exerts on the quality of video streaming over IP networks. It also describes a new numerical tool – QoSCalc (DASH-HTTP) which has been used to analyze MPEG-DASH under different use scenarios. The results are presented graphically and their interpretation is provided

Selection Methodology

Quality of live video streaming technology is based on quality of Experiences parameters (QoE). Approaching the peer-to-peer (P2P) or peer-assisted networks as a sympathetic solution is highly required, especially in light of its authentic scalability and its extremely low initial cost requirements. However, the design of robust, efficient, and performing P2P streaming systems remains a high challenge when real-time constraints are part of the quality of service (QoS), as in TV distribution or conferencing applications. One of the P2P main issues that affect the quality of streaming is the neighbor selection methodology. The proposed work presents an effective mesh-based neighbor selection approaches for video streaming – Uniform Peer Distribution Algorithm (UPDA) – based on QoS and QoE Parameters. UPDA shortens the latency to be ranging from 10 ms to 50 ms servicing up to 4000 online peers under failure / recovery tests. Simulation results demonstrate that the proposed UPDA achieves good performance in End-to End delay with a percentage of 10.4 % and packet delay variation about 2% compared to random neighbor selection method.

P2p Overlay

Today some of the most popular and successful applications over the Internet are based on Peer-to-Peer (P2P) solutions. Online Social Networks (OSN) represent a stunning phenomenon too, involving communities of unprecedented size, whose members organize their relationships on the basis of social or professional friendship. This work deals with a P2P video streaming platform and focuses on the performance improvements that can be granted to those P2P nodes that are also members of a social network. The underpinning idea is that OSN friends (and friends of friends) might be more willing to help their mates than complete strangers in fetching the desired content within the P2P overlay. Hence, an approach is devised to guarantee that P2P users belonging to an OSN are guaranteed a better service when critical conditions build up, i.e., when bandwidth availability is scarce. Different help strategies are proposed, and their improvements are numerically assessed, showing that the help of direct friends, two-hops away friends and, in the limit, of the entire OSN community brings in considerable advantages. The obtained results demonstrate that the amount of delivered video increases and the delay notably decreases, for those privileged peers that leverage their OSN membership within the P2P overlay.

Multicast Streaming

Video streaming is becoming one of the most important services deployed over telecommunication networks such as the Internet and triple-play operators’ networks. This service differs from the rest in being loss sensitive and highly delay sensitive and requiring a considerable amount of bandwidth in order to offer a smooth transmission of packets through the network. While upgrading network elements with quality of service and multicast transmission capabilities becomes prohibitive for most network operators, peer-to-peer (P2P) architectures appear to be smart and efficient solutions to the previous issues. Many different P2P systems have been proposed and deployed to offer reliable video streaming services. These approaches address issues such as multicast transmission, quality of service enablement, mobility robustness, and video distribution according to network and user device capabilities. This chapter gives an overview of the different issues related to performance and reliability in multicast streaming over wireless networks and presents several alternatives facing them, including amendments to the already existing multicast mechanism of data distribution, video scalability and how peer-to-peer networking can provide a cost-effective solution to such problems.

SummaryThere is concern regarding the quality of information about mental health problems on the internet. A trial was carried out to see whether sending feedback to website administrators about the quality of information on their website would lead to an improvement (ACTRN12609000449235). Fifty-two suicide prevention websites were identified by means of an online search. The quality of information about how to help someone who is suicidal was scored against expert consensus guidelines. Websites were randomised to receive feedback or serve as controls. The information on the websites varied greatly in quality. However, feedback did not lead to an improvement.

Simulation Results

The popularity of the video services on the Internet has evolved various mechanisms that target the Quality of Experience (QoE) optimization of video traffic. The video quality has been enhanced through adapting the sending bitrates. However, rate adaptation alone is not sufficient for maintaining a good video QoE when congestion occurs. This paper presents a cross-layer architecture for video streaming that is QoE-aware. It combines adaptation capabilities of video applications and QoE-aware admission control to optimize the trade-off relationship between QoE and the number of admitted sessions. Simulation results showed the efficiency of the proposed architecture in terms of QoE and number of sessions compared to two other architectures (adaptive architecture and non-adaptive architecture ).

SummaryIn the United States today, digital versions of current decisions, bills, statutes, and regulations issued by federal and state governments are widely available on publicly accessible Web sites. Worldwide, official (defined as “authoritative,” or “the official” word of the law) legal information issued by international organizations and foreign governments is also becoming available on the Web. However, there are currently no standards for the production and authentication of digital documents. Moreover, the information is sometimes available only for a short time and then disappears from the site. No guidelines exist either to promote a uniform way to cite to digital legal materials.This article examines the contents of legal data and information on the Internet, with a special focus on the United States. It then evaluates the quality of the data, its impact on legal research and access to legal information, and addresses some issues raised by the digital medium, such as its reliability and permanent access concerns.
