IPTV Technology: How It Works and Its Future in the Digital Era

2010 Fifth International Conference on Information and Automation for Sustainability, 2010

This tutorial presents on IPTV technology. Internet Protocol television (IPTV) is a system through which television services are delivered using the architecture and networking methods of the Internet Protocol suite over a packet-switched network infrastructure. IPTV services may be classified into three main groups: live television, time-shifted programming, and video on demand.

ABSTRACT IPTV, or Internet-Based TV broadcasting is going to significantly change the way people obtain information, get entertainment, and possibly collaborate with each other. Compared with today's TV system, IPTV gives the viewers more choice as to what to watch and how to watch, and allows users to broadcast their own programs easily, thus “democratizing” information broadcasting.

IP Protocol Television (IPTV) challenges the traditional television industry by opening the Internet to high quality real time television content delivery. This paper compares between two concepts; namely: IPTV and internet TV. Furthermore, analysis is conducted based on some practical tests' results implemented in the literature. This study evaluates the impact of the Quality of Service (QoS) parameters into IPTV real-time stream environment.

After the success of carrying voice over IP networks, the dream of an IP-based television is being turned into reality with the research and standardization efforts. Today, standardization organizations, researchers, as well as commercial companies are putting huge efforts to make Internet Protocol TeleVision (IPTV) successful. The achieved successes of IPTV are due to many factors, including mainly the advanced video coding techniques, the continuously increasing Internet bandwidth that end users have been enjoying and the mature wired and wireless networking protocols and architectures. Although IPTV still faces many challenges, many content providers as well as Internet Service Providers (ISPs) already started to deliver IPTV services to customers. Nevertheless, the way ahead is still long and more efforts are required. This paper surveys a breadth of research areas related to IPTV. It first discusses the general service architecture of IPTV services and diagnostics in these architectures. It then turns the attention to surveying encoding techniques that can serve as enablers for future IPTV especially Scalable Video Coding. Then, various IPTV distribution approaches including peer-to-peer and Content Distribution Networks are discussed. After that, major work on security and privacy concerns in IPTV is tackled. Finally, a discussion of the major work in wireless IPTV services is discussed with focus on LTE-based service offering. We believe such a survey will be very helpful for researchers who would like to educate themselves in the overall landscape of IPTV before digging deeper to address open research problems to bring IPTV closer to reality.

Video oriented services are taking the lead in terms of revenue in the current Internet environment. In order to tap this revenue, Telcos are resorting to serious measures such as moving to Next Generation Network (NGN) where they can provide QoS for services that demand this feature, such as, IPTV. IPTV is more than just what its name implies and

As more and more content migrates to the Internet, "personal" video choices are becoming the norm not the exception. The impact of Internet content and IP based business of video distribution is still difficult to evaluate. However, there is obviously no turning back as this content pervades the home and the community. Driven in large part by the near-ubiquitous IP-based communication services, the TV experience has been extended over the years to embrace many of the same ancillary services provided by web applications. This new TV promises to deliver a world of content and services to "any device, anytime, anywhere". This paper addresses the architecture, the value chain and the technical and business challenges of implementing this new connected mobile and social TV experience.

The goal of this paper is to shed some light on the meanderings of the IPTV route. Regional Bell operating companies' (RBOCs') last chance: The RBOCs are experiencing an erosion of their access line and voice revenue. It has been compensated by the DSL growth and, for BellSouth, SBC and Verizon, the health of their cellular properties. However, as MSOs finally deploy VoIP, they become triple-play providers. The RBOCs must add video to their voice and data offering. It is a pivotal moment for the RBOCs; they have no choice but to succeed. The RBOCs already tried video service in the mid-'90s; they failed miserably and at great expense. This time around, anything other than complete success will spell their demise. The current asymmetric digital subscriber line (ADSL) network cannot support IPTV. It must be overhauled. Trenches have to be dug, fiber/copper have to be installed, and new outside electronic equipment-new routers, a new OSS/BSS, a video head end, a video server, a set-top box (STB) or set-top terminal (STT)-have to be purchased. This heavy investment should allow the telecom equipment manufacturers that have survived the nuclear telecom winter to enjoy some springlike weather. It will also lead to further concentration in the industry. IPTV-Microsoft's Trojan horse for the living room?: Microsoft has won major IPTV deals, making its MSTV middleware solution the de facto reference. After dominating the office desktop, it is clear that Microsoft is positioning itself to dominate the living room. Microsoft is offering one-stop shopping for acquisition server, delivery server, video server, and digital rights management; but at its core, it is an operating system company. It will integrate features into the operating system of the STB or STT as it sees fit and will most likely exit peripheral businesses (video server for example). Small is beautiful: There are many successful deployments of IPTV across the world. Most of them are by small or medium-size operators. Large operators are struggling. Five facts about middleware: 1. More than 50 percent of the effort to develop and integrate middleware with the rest of the system is spent on the STB. 2. Middleware scales well, and supporting hardware is not a cost factor. 3. Middleware database is small by today's database standard. 4. Scripting language in the STB is too slow. Java is better, but embedded C/C++ offers the best performance. 5. A middleware client program has a small object footprint (below 32 MB). The last 100 meters: Telcos have a good understanding of the core/metro network and the outside loop. The challenges of the last 100 meters remain. Most IPTV providers confess that it still takes an average of four hours to set up a customer (including network access termination). A

For half a century, television has been a dominant and pervasive mass media, driving many technological advances. Despite its widespread usage and importance to emerging applications, the ingrained TV viewing habits are not completely understood. This was primarily due to the difficulty of instrumenting monitoring devices at individual homes at a large scale. The recent boom of Internet TV (IPTV) has enabled us to monitor the user behavior and network usage of an entire network. Such analysis can provide a clearer picture of how people watch TV and how the underlying networks and systems can better adapt to future challenges. In this paper, we present the first analysis of IPTV workloads based on network traces from one of the world's largest IPTV systems. Our dataset captures the channel change activities of 250,000 households over a six month period. We characterize the properties of viewing sessions, channel popularity dynamics, geographical locality, and channel switching behaviors. We discuss implications of our findings on networks and systems, including the support needed for fast channel changes. Our data analysis of an operational IPTV system has important implications on not only existing and future IPTV systems, but also the design of the open Internet TV distribution systems such as Joost and BBC's iPlayer that distribute television on the wider Internet.

The world of telecommunications continues to provide radical technologies. Offering the benefits of a superior television experience at reduced long-term costs, IPTV is the newest offering. Deployments, however, are slow to be rolled out; the hardware and software support necessary is not uniformly available. This paper examines the challenges in providing IPTV services and the limitations in developments to overcome these challenges. Subsequently, a proposal is made which attempts to help solve the challenge of fulfilling real-time multimedia transmissions through provisioning for differentiated services. Initial implementations in Opnet are documented, and the paper concludes with an outline of future work.
