This book details the past, present, and future of IPTV delivery networks, which employ IP-based networking techniques and topologies to support real time and scheduled television services. It also covers several other related issues of IPTV, namely: broadcasting, buffering, contents storage and allocation, security and privacy, QoS, QoE, and mobility. It is written for professionals and researchers who are working in the field of multimedia and delivery networking technologies, and can also can be utilized as a reference book to teach the courses related to delivering and streaming real time and scheduled multimedia contents. Moreover, the book provides a practical guide to designing and optimizing the IPTV delivery networks so that it can be beneficial for professionals in the IPTV industry. Currently, much of the available literature discusses only the basics of IPTV; there is no book which discusses in depth the IPTV Delivery Networks for both live and on-demand IPTV services. For the researchers and professionals, such a book that covers all the aspects of IPTV delivery networks comprehensively is needed for a deeper understanding of the technology. Moreover, the issues of delivering IPTV over 3G/4G/LTE are still hot research areas alongside the issues of heterogeneity in the delivering process. Based on that, the motivation of the authors is to assist the shareholders of IPTV Delivery Networks in building strong knowledge about delivery networks and related technologies and issues.
