Delay Efficient Method for Delivering IPTV Services

Internet Protocol Television (IPTV) is a system through which Internet television services are delivered using the architecture and networking methods of the Internet Protocol Suite over a packet-switched network infrastructure, e.g., the Internet and broadband Internet access networks, instead of being delivered through traditional radio frequency broadcast, satellite signal, and cable television (CATV) formats. IPTV provides mainly three services: live TV, catch up TV, and video on demand (VoD).This paper focuses on delivering the live TV services by exploiting the virtualised cloud architecture of the IPTV and statistical multiplexing. The VoD tasks are prescheduled so that there will be less Instant Channel Change (ICC) delay. We select a proper scheduling algorithm for rescheduling the VoD tasks. We then implement the scheduling algorithm for preshifting the VoD tasks. Key Terms: IPTV, Statistical multiplexing, Virtualization, Vo D, Live TV, Scheduling, ICC Delay
