Determining the feasibility of a method for improving bandwidth utilization of cable networks

While the cable television industry has made significant investments in infrastructure to improve the number and quality of services delivered to their end customers, they still face the problem of limited bandwidth of signals down the last mile of coaxial cable to the subscriber premises. This thesis investigates an approach devised by the author to overcome this limitation. The method involves clustering of channels in both the upstream and downstream directions in a DOCSIS compliant cable system. A model of this approach is made and the theoretical maximum throughput is calculated for several scenarios. Results are compared to performance of existing systems. It is found that proposed approach yields significantly more throughput for a given RF bandwidth than others in the comparison

Capacity Behaviour using WSDV Scheme over WiMAX

The objective of this project is to create Mobile Worldwide Interoperability for Microwave Access (WiMAX) for 4th generation mobile wireless networks in which it is foreseen that mobile Television (TV) services will reproduce rapidly. In television applications are bandwidth hogs that cause a challenging capacity problem in wireless networks. To address this challenge, a novel scheme for mobile Television services over WiMAX network, called the Wireless Switched Digital Video (WSDV) scheme, is proposed. Compared with the conventional broadcast or unicast schemes, the hybrid approach introduced in the proposed WSDV approach exploits the merits of two conventional schemes and mitigates their demerits, which enables it to increase wireless capacity for mobile Television services. The analytical model can capture the details of WiMAX resource allocation and take into consideration the popularity of the mobile Television contents being viewed by users enabling it to provide an accurate estimate of the amount of bandwidth required for WiMAX TV services and also enabling a designer to optimally select the number of channels via the WSDV service while meeting a desired level of blocking probability. The proposed optimized scheme outperforms the conventional schemes with respect to blocking probability. Finally, an end-to-end solution to the WSDV scheme is also presented

Statistical Information of the Increased Demand for Watch the VOD with the Increased Sophistication in the Mobile Devices,Communications and Internet Penetration in Asia

As the rapid progress of the media streaming applications such as video streaming can be classified into two types of streaming, Live video streaming, Video on Demand (VoD). Live video streaming is a service which allows the clients to watch many TV channels over the internet and the clients able to use one operation to perform is to switch the channels. Video on Demand (VoD) is one of the most important applications for the internet of the future and has become an interactive multimedia service which allows the users to start watching the video of their choice at anytime and anywhere, especially after the rapid deployment of the wireless networks and mobile devices. In this paper provide statistical information about the Internet, communications and mobile devices etc. This has led to an increased demand for the development, communication and computational powers of many of the mobile wireless subscribers/mobile devices such as laptops, PDAs, smart phones and notebook. These techniques are utilized to obtain a video on demand service with higher resolution and quality. Another objective in this paper is to see Malaysia ranked as a fully developed country by the year 2020.Comment: 17 pages, 17 figures, 4 tables; The International Journal of Multimedia & Its Applications (IJMA) Vol.3, No.4, November 201

Network Neutrality after Comcast: Toward a Case-by-Case Approach to Reasonable Network Management

The Federal Communications Commission’s recent Comcast decision has rejected categorical, ex ante restrictions on Internet providers’ ability to manage their networks in favor of a more flexible approach that examines each dispute on a case-by-case basis, as I have long advocated. This book chapter, written for a conference held in February 2009, discusses the considerations that a case-by-case approach should take into account. First, allowing the network to evolve will promote innovation by allowing the emergence of applications that depend on a fundamentally different network architecture. Indeed, as the universe of Internet users and applications becomes more heterogeneous, it is only natural for the services that networks provide to diversify in response. Allowing prioritized services would also benefit consumers by allowing them to purchase only the level of service that they need. More diverse business relationships would also allow the network to reflect the insights of two-sided markets, which suggest that the money flowing through the network will often vary in magnitude and direction over time. Any mandated access regime would also confront substantial implementation difficulties and would raise the capital costs of deploying new network facilities. Lastly, a case-by-case approach to network neutrality would provide better ex ante guidance if it incorporated the jurisprudence developed by the Supreme Court applying the rule of reason under the antitrust laws

Online high-definition video adoption among college students

Department Head: Greg Luft.2010 Summer.Includes bibliographical references (pages 82-85).As more online video products are available in high-definition format, online high-definition video (online HD video), as a specific application of HD IPTV, has become more appealing to consumers. This study applied Rogers' (2003) diffusion of innovation theory to analyze the decision-making processes used in the adoption of the new technology. College students (n=242) completed a survey that examined the effects of technology use, media consumption, demographics (gender and family income), personality traits (innovativeness-venturesomeness and social integration), awarenessknowledge, perceptions about characteristics of online HD video, and perceptions about the benefits and risks of adoption. Dependent variables included attitudes among all respondents, satisfaction among adopters, and behavioral intent among non-adopters. Favorable attitudes were positively related to being male, more knowledge, more time spent with the broadband Internet, more innovative and venturesome in personality, more perceptions about benefits and fewer perceptions about risks, more perceptions about the five characteristics of online HD video. Satisfaction among adopters (n=187) was positively related to being male, innovativeness-venturesomeness and social integration personality, knowledge, perceived characteristics of online HD video, and perceptions about more benefits and less risks. Findings related to behavioral intent among nonadopters were difficult to analyze due to the small number of respondents (n=55), who were predominantly female. Behavioral intent was positively related to Rogers' notions about relative advantage, compatibility and observability, and perceptions about benefits and risks, but negatively related to a focus on social integration. No differences based on family income were found for attitude, behavioral intent or satisfaction

Systems analysis of emerging IPTV entertainment platform : stakeholders, threats and opportunities

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2008.Includes bibliographical references (p. 140-144).Why do certain types of companies, goods, services survive and others do not. Why does one set continuously reinvent themselves and others wither away and die? Why does Cisco continue to provide exciting and innovative networking products, while companies like Cabletron die? Several academics believe that a dominant factor is that winners are able to create robust and effective product platforms. These platforms are able to cater to changing customer needs. On the winning side, the platform leader is effectively able to manage the various conflicts that are present in the platform ecosystem. On the loosing team, often there is no platform leader!I believe that effective platform leadership, platform architecture play a key role in product success.In this thesis, I plan to compare two large platforms. These are the IPTV platform and the conventional cable based TV platform. Both are competing with each other to provide similar services to the same customer set. I have coined the term 'Mega Platform" to describe such large platforms. . As part of this comparison I will develop a set of metrics or comparison points which will help compare the two competing platforms. Please note that the purpose of this thesis is not to prove that there is a strong correlation between platform success and market success.by Shantnu Sharma.S.M
