Multicast As A Mandatory Stepping Stone For An IP Video Service To The Big Screen (2014)

By Amit Eshet, John Ulm, Uzi Cohen, Carol Ansley, ARRIS

With the availability of new technology, namely home gateways with 16 or more DS tuners and CCAP platforms, the transition to a managed IP video service is now becoming feasible and cost-effective. The biggest challenge remaining is the bandwidth; especially with the continual growth of high-speed data service leading to constant contention among the services for the limited spectrum resources available. This paper provides a window into the viewing habits in 2013. We show that linear content is still the number one service with the number of peak time viewers at over 75%. We compare the efficiencies of switched multicast, and unicast (native for ABR delivery) approaches. Furthermore, to give indication of the transition period to a full IP service, we further present the significant benefits of multicast even at small groups of subscribers. We conclude by introducing a Multicast assisted ABR architecture that offers the benefits of multicast as well as building upon a single infrastructure to enable an IP video service to all devices in and outside the home
