This webinar explains how IPTV is sent over the network using DSL in the last mile (fiber-to-the-node/cabinet), the associated challenges and reliability issues, and how some DSL test results point to service affecting problems.

IPTV is a sensitive end-to-end service from the content provider to the customer’s TV. It requires extra bandwidth for reliability, and is typically delivered over ADSL2+ and VDSL2 provisioned at high rates. And, similar to carrier circuits, its loop quality requirements are more stringent than voice. For example, T and E Carriers were limited in the amount of bridged tap permitted in order to maintain sufficient SNR and low bit error rates. For IPTV over high speed DSL, additional band-width robbing factors cannot be ignored: those impacting SNR (not just attenuation, but also balance, noise and crosstalk) and impulse noise.
