Soohong Park Samsung Electronics Architectures and Approaches Mobile Tv plus Ip Iptv plus Mobile

Seong-Ho Jeong Hankuk University of Foreign Studies M obile IPTV lets mobile users transmit and receive multimedia traffic, such as TV signals, video, audio, text, and graphics, through IP-based networks with the support of quality of service (QoS) and quality of experience (QoE), security, mobility, and interactivity. In short, mobile IPTV extends many IPTV services to mobile users. To coordinate and promote development of global IPTV standards, the ITUT in 2006 formed a focus group called FG IPTV, which took into account the existing work of ITU-T study groups and other standards development organizations. Then, in January 2008, the IPTV Global Standards Initiative (IPTV-GSI) took over the IPTV standardization role. In this article, we describe the current status of mobile IPTV standardization as well as mobile IPTV approaches and technical challenges. Additionally, we propose an efficient signaling scheme to support QoS for seamless mobile IPTV services. QoS support is critical for video delivery systems, especially in the mobile environment, and a requirement for viewer satisfaction.
