Analysis and implementation of the Large Scale Video-on-Demand System

Next Generation Network (NGN) provides multimedia services over broadband based networks, which supports high definition TV (HDTV), and DVD quality video-on-demand content. The video services are thus seen as merging mainly three areas such as computing, communication, and broadcasting. It has numerous advantages and more exploration for the large-scale deployment of video-on-demand system is still needed. This is due to its economic and design constraints. It's need significant initial investments for full service provision. This paper presents different estimation for the different topologies and it require efficient planning for a VOD system network. The methodology investigates the network bandwidth requirements of a VOD system based on centralized servers, and distributed local proxies. Network traffic models are developed to evaluate the VOD system's operational bandwidth requirements for these two network architectures. This paper present an efficient estimation of the of the bandwidth requirement for the different architectures.Comment: 9 pages, 8 figure

Multimedia delivery in the future internet

The term “Networked Media” implies that all kinds of media including text, image, 3D graphics, audio and video are produced, distributed, shared, managed and consumed on-line through various networks, like the Internet, Fiber, WiFi, WiMAX, GPRS, 3G and so on, in a convergent manner [1]. This white paper is the contribution of the Media Delivery Platform (MDP) cluster and aims to cover the Networked challenges of the Networked Media in the transition to the Future of the Internet. Internet has evolved and changed the way we work and live. End users of the Internet have been confronted with a bewildering range of media, services and applications and of technological innovations concerning media formats, wireless networks, terminal types and capabilities. And there is little evidence that the pace of this innovation is slowing. Today, over one billion of users access the Internet on regular basis, more than 100 million users have downloaded at least one (multi)media file and over 47 millions of them do so regularly, searching in more than 160 Exabytes1 of content. In the near future these numbers are expected to exponentially rise. It is expected that the Internet content will be increased by at least a factor of 6, rising to more than 990 Exabytes before 2012, fuelled mainly by the users themselves. Moreover, it is envisaged that in a near- to mid-term future, the Internet will provide the means to share and distribute (new) multimedia content and services with superior quality and striking flexibility, in a trusted and personalized way, improving citizens’ quality of life, working conditions, edutainment and safety. In this evolving environment, new transport protocols, new multimedia encoding schemes, cross-layer inthe network adaptation, machine-to-machine communication (including RFIDs), rich 3D content as well as community networks and the use of peer-to-peer (P2P) overlays are expected to generate new models of interaction and cooperation, and be able to support enhanced perceived quality-of-experience (PQoE) and innovative applications “on the move”, like virtual collaboration environments, personalised services/ media, virtual sport groups, on-line gaming, edutainment. In this context, the interaction with content combined with interactive/multimedia search capabilities across distributed repositories, opportunistic P2P networks and the dynamic adaptation to the characteristics of diverse mobile terminals are expected to contribute towards such a vision. Based on work that has taken place in a number of EC co-funded projects, in Framework Program 6 (FP6) and Framework Program 7 (FP7), a group of experts and technology visionaries have voluntarily contributed in this white paper aiming to describe the status, the state-of-the art, the challenges and the way ahead in the area of Content Aware media delivery platforms

Video-on-Demand over Internet: a survey of existing systems and solutions

Video-on-Demand is a service where movies are delivered to distributed users with low delay and free interactivity. The traditional client/server architecture experiences scalability issues to provide video streaming services, so there have been many proposals of systems, mostly based on a peer-to-peer or on a hybrid server/peer-to-peer solution, to solve this issue. This work presents a survey of the currently existing or proposed systems and solutions, based upon a subset of representative systems, and defines selection criteria allowing to classify these systems. These criteria are based on common questions such as, for example, is it video-on-demand or live streaming, is the architecture based on content delivery network, peer-to-peer or both, is the delivery overlay tree-based or mesh-based, is the system push-based or pull-based, single-stream or multi-streams, does it use data coding, and how do the clients choose their peers. Representative systems are briefly described to give a summarized overview of the proposed solutions, and four ones are analyzed in details. Finally, it is attempted to evaluate the most promising solutions for future experiments. Résumé La vidéo à la demande est un service où des films sont fournis à distance aux utilisateurs avec u

Performance Evaluation of MPEG-4 Video Transmission over IP-Networks: Best-Effort and Quality-of-Service

The demand for video communication over internet has been growing rapidly in recent years and the quality of video has become a challenging issue for video transmission. Different types of video coding standards like MPEG-2 and MPEG-4 have been developed to support application like video transmission. MPEG-2 which requires high bit rate transmission has been successful video standard for DVD and satellite digital broadcasting. On the other hand, MPEG-4 supports low bit rate and is suitable for transmitting video over IP networks. In this paper, MPEG-4 Video standard has been used for evaluating the performance of video transmission over two IP networks:- Best-effort and Quality of Service (QoS). For both of the best-effort and QoS IP networks, peak signal noise ratio (PSNR), throughput, frame and packet statistics have been considered as performance metrics. The calculated values of these performance metrics reflect that video transmission over QoS IP network is better than that of the best-effort network.

FLOSSTV Free, Libre, Open Source Software (FLOSS) within participatory 'TV hacking' Media and Arts Practices

This research operates in the context of a European political discourse, where the main concern is counter­cultural approaches to non­ mandatory collaboration and contractual agreements. FLOSSTV (Free, Libre, Open Source Software TV) covers a broad range of practices, from television via documentary up to media arts productions. This thesis documents the endeavour to formulate a policy for FLOSS culture. FLOSSTV studies the impact of new intellectual property legislation on media production, as well as conceptions and applications of collective authorship and alternative licensing schemes. FLOSSTV sets out to explore methods that can facilitate media and arts practitioners wishing to engage in collaborative media productions. The thesis sets out to investigate the theories and histories of collaborative media and arts productions in order to set the ground for an exploration of the tools, technologies and aesthetics of such collaborations. The FLOSSTV thesis proposes a set of contracts and policies that allow for such collaborations to develop. It is through practice that this research explores FLOSS culture, including its methods, licensing schemes and technologies. In order to focus the research within the field of FLOSSTV I initiated the practice ­based Deptford.TV pilot project as the central research experiment for the FLOSSTV thesis. DVD ONE contains a series of films produced collaboratively for Deptford.TV that express the characteristics and contractual arrangements of FLOSS culture. Deptford.TV is an online audiovisual database primarily collecting media assets around the Deptford area, in South­East London, UK. Deptford.TV functions as an open, collaborative platform that allows artists, film­makers, researchers and participants of the local workshops in and around Deptford, and also beyond Deptford, to store, share, re­edit and redistribute their footage and projects. The open and collaborative nature of the Deptford.TV project demonstrates a form of shared media practice in two ways: audiences become producers by submitting their own footage, and the database enables the contributors to interact with each other. Through my practice­lead research project Deptford.TV I argue that, by supporting collaborative methods and practices, FLOSS (Free, Libre, Open Source Software) can empower media and arts practitioners to collaborate in production and distribution processes of media and arts practices

Indexing, browsing and searching of digital video

Video is a communications medium that normally brings together moving pictures with a synchronised audio track into a discrete piece or pieces of information. The size of a “piece ” of video can variously be referred to as a frame, a shot, a scene, a clip, a programme or an episode, and these are distinguished by their lengths and by their composition. We shall return to the definition of each of these in section 4 this chapter. In modern society, video is ver

Security-Camera Proposal for the Dynamy Youth Center

Dynamy is an educational program that sponsors a Youth Center for high schools students. Recently, Dynamy officials have considered security cameras to secure the building from outsiders. To assess Dynamy\u27s Security Camera needs, I went to the University of Pennsylvania to learn from the most secure educational facility in America. I also met with professional CCTV installers from ADT Security, who even gave a free on-site estimate. I was able to draft a security camera proposal for the Dynamy Youth Center. The proposal asks for 8 cameras to be installed by Dynamy officials to secure the facility\u27s computer labs, conference rooms, office areas, and entrance ways. The security camera proposal explains how to buy a CCTV system, where to place cameras, and how to route cabling
