To facilitate network performance analysis and simulations for IPTV traffic, a two-level Markovian traffic model is proposed in the paper. The model considers both spatial and temporal correlation in MPEG encoded video sequences, so it can mimic the highly variable data rate (VBR) behavior of IPTV sources. The model contains a Group of Pictures (GoP)- level Markov chain and a frame-level Markov chain,...
Telecommunication service providers are racing to deliver IPTV/video on demand (VoD), voice, and data, the so called triple-play services. IPTV traffic, supported by the UDP protocol, has highly variable data rates and stringent quality of services (QoS) requirements in terms of delay and loss. Data and VoD flows are normally supported by TCP, which has its own congestion control loop to adjust the...
IPTV is considered to be the next killer application. A key, challenging issue is in-home IPTV distribution with affordable deployment cost and sufficient flexibility, scalability, and reliability. In this article, we first survey and compare the emerging wired and wireless communication technologies for broadband home networks, including transmission over power lines, phone lines, coaxial cables...
Understanding the pros and cons of different distribution technologies is the first step in designing efficient future broadband home networks for IPTV service delivery. In this paper, we survey the emerging wired and wireless communication technologies, including powerline, phone line, UltraWide Band (UWB), millimeter wave (MMW), etc., which are promising candidates for distributing broadband signals...
