Internet Protocol Television

The Internet protocol television brought seamless potential that has revolutionized the media and telecommunication industries by providing a platform for transmitting digitized television services. However, zapping delay is a critical factor that affects the quality of experience in the Internet protocol television. This problem is intrinsically caused by command processing time, network delay, jitter, buffer delay, and video decoding delay. The overarching objective of this paper is to use a hybrid delivery method that agglutinates multicast- and unicast-enabled services over a converged network to minimize zapping delay to the bare minimum. The hybrid method will deliver Internet protocol television channels to subscribers using the unicast stream coupled with differentiated service quality of experience when zapping delay is greater than 0.43 s. This aids a faster transmission by sending a join message to the multicast stream at the service provider zone to acquire the requested channel. The hybrid method reported in this paper is benchmarked with the state-of-the-art multicast stream and unicast stream methods. Results show that the hybrid method has an excellent performance by lowering point-to-point queuing delay, end-to-end packet delay, and packet variation and increasing throughput rate.

El siguiente artículo presenta un análisis de las métricas de QoS (Quality Of Service) más relevantes para el servicio IPTV (Internet Protocol Television) sobre una infraestructura de red Móvil basada en MIPV4 y MIPV6, el cual es realizado con el Sniffer Wireshark. Es de suma importancia evaluar las métricas en el servicio, dado que esto permitirá observar cuál es el rendimiento de la red durante la trasmisión de cualquier servicio multimedia, dependiendo del protocolo móvil. De acuerdo a lo anterior, el resultado logrado es que en MIPV6 es más eficiente la calidad de la red para trasmitir un servicio IPTV, dado que las métricas evaluadas arrojaron que hay menos retardo y pérdidas de paquetes durante la trasmisión, esto se puede notar dado que en MIPV4, cuando el MN(Mobile Node) se encuentra ubicado en el FA(Foreing Agent), la pérdida es de 7% mientras que en MIPV6 es de 2%, favoreciendo la trasmisión del servicio hacia MIPV6. Para continuar con el trabajo, se recomienda evaluar la QoE (Quality Of Experience) del servicio en los diferentes protocolos móvil, con el fin de lograr un acercamiento a lo que puedan percibir o sentir los usuarios sobre el servicio.

Internet Protocol Television is a system that has revolutionized the media and telecommunication industries. It provides the platform for transmitting digitised television services across the Internet Protocol infrastructure. Internet Protocol Television took advantage of the Internet service convergence by providing seamless interactivity, time shifting, video on demand and pay per view to subscribers. However, zapping delay is a critical problem that deters the switching intention of terrestrial subscribers and the widespread of Internet Protocol Television services. Subscribers often experience this zapping delay problem in Internet Protocol Television when switching channels, which makes subscribers, wait for several seconds before the desired channel is found and made available. The zapping delay problem is intrinsically caused by video stream end-to-end delay, buffering delay, network jitter and traffic load. In the last few decades, a lot of frameworks, for instance, those based on multiple channels, have been proposed to reduce zapping delay in Internet Protocol Television. Such frameworks are implemented at the subscriber level, network level or video level. However, high bandwidth is still required to make the existing frameworks work effectively, which is an intrinsic limitation because not all subscribers can afford the cost of high bandwidth. This research develops a unified framework that takes the advantages provided at the subscriber level and network level to solve the zapping delay problem in Internet Protocol Television. It is possible to reduce zapping delay in Internet Protocol Television using an effective framework to aid faster channel switching and increase the quality of experience. The framework being proposed in this research is faster than a regular stream and it reduces the zapping delay to the bare minimum. The framework has been validated at both subscriber and network levels, which indicates that as traffic load increases at a set bandwidth within the converged network, packet end to end delay and network jitter should be reduced in order to eliminate zapping delay. Furthermore, the encoded and decoded video sequence available to the subscriber is evaluated using popular quantitative metrics and mean opinion score to determine subscriber perceptions of video quality through the salient object that will interest the subscriber in the video sequence displayed in order to aid a high satisfaction level video quality of experience. A large-scale implementation of the proposed framework by a telecommunication firm promises to generate revenue for the firm. In addition, the implementation and practical deployment of the proposed framework would also benefit subscribers to enjoy unlimited Internet Protocol Television services at reduced cost.

Routing is a design way to pass the data packet. User is assigns the path in a routing configuration. A significant role played by the router for providing the dynamic routing in the network. Structure and Configuration are different for each routing protocols. Next generation internet protocol IPv6 which provides large address space, simple header format. It is mainly effective and efficient routing. It is also ensure good quality of service and also provide security. Routing protocol (OSPFv3) in IPv6 network has been studied and implemented using ‘cisco packet tracer’. ‘Ping’ the ping command is used to check the results. The small virtual network created in Cisco platform .It is also used to test the OSPFv3 protocol in the IPv6 network. This paper also contains step by step configuration and explanation in assigning of IPv6 address in routers and end devices. The receiving and sending the packet of data in a network is the responsibility of the internet protocol layer. It also contains the data analysis of packet forwarding through IPv6 on OSPFv3 in simulation mode of cisco packet virtual environment to make the decision eventually secure and faster protocol in IPv6 environment.

Meta Analyses

Channel zapping delays are inconveniences that are often experienced by the subscribers of Internet protocol television (IPTV). It is a major bottleneck in the IPTV channels switching system that affect the quality of experience of users. Consequently, numerous channels switching approaches to minimize zapping delay in IPTV have been suggested. However, there is little knowledge reported in the literature on the determination of the strength of the evidence presented on the approaches of reducing zapping delay in IPTV, which is the prime purpose of this study. The extraction of the relevant articles was designed following the technique of preferred reporting items for systematic reviews and meta-analyses (PRISMA). All the included research articles were searched from the widely used databases of Google Scholar, and Web of Science. All statistical analyses were performed with the aid of the random-effects model implementation in Stata version 15. The overall pooled estimated delay component was presented in forest plots. Overall, thirteen studies were included in the meta-analysis and the overall pooled estimate was 10% (95% CI: 7%, 30%)). Experimental studies have shown that virtual elimination of IPTV zapping delay is possible for a relevant chunk of channel switching requests.

The founding of the Bell Telephone System, the public switched telephone network (PSTN), has evolved into a highly successful global telecommunications system. It is designed specifically for voice communications, and provides a high quality of service and ease of use. It is supported by sophisticated operations systems that ensure extremely high dependability and availability. Over the past 100 years, it has been a showcase for communications engineering and led to groundbreaking new technologies (e.g., transistors, fiber optics). Yet it is remarkable that many public carriers see their future in Internet protocol (IP) networks, namely the Internet. Of course, the Internet has also been highly successful, coinciding with the proliferation of personal computers. It has become ubiquitous for data applications such as the World Wide Web, e-mail, and peer-to-peer file sharing. While it is not surprising that the Internet is the future for data services, even voice services are transitioning to voice over Internet protocol (VoIP). This phenomenon bears closer examination, as a prime example explaining the success of the Internet as a universal communications platform. This chapter gives a historical development of the Internet and an overview of technical and nontechnical reasons for the convergence of services.

Increasing Demand

Transmission of video traffic over the Internet has grown exponentially in the past few years<br>with no sign of waning. This increasing demand for video services has changed user expectation of quality. Various mechanisms have been proposed to optimise the Quality of Experience (QoE) of end users’ video. Studying these approaches are necessary for new methods to be proposed or combination of existing ones to be tailored. We discuss challenges facing the optimisation of QoE for video traffic in this paper. It surveys and classifies these mechanisms based on their functions. The limitation of each of them is identified and future directions are highlighted.
