A possibility of estimation of IPTV QoS parameters by using DSL transceivers physical layer parameters

This paper analyses a dependence of standard definition IPTV service continuity error on code violation block codes. A very reliable method of evaluating of several IPTV QoS parameters by observing the parameters of physical layer of DSL transceivers was introduced. Also, an ability to use the procedures, which have already implemented at common ATU-R and ATU-C ADSL2+ modems for estimation of IPTV QoS parameters, without appropriate performance monitoring system implemented was discussed.
