IPTV increases need for monitoring solutions

October 17, 2013 - 5:34pm
IPTV environments contain more pass-through points in end-to-end broadcast systems.

More devices equals more monitoring.

That simple equation creates challenges for IP video transport, wrote TV Technology contributor Wes Simpson. End-to-end QoS system monitoring solutions that optimize video transport and maintain signal quality are vital in scaling broadcast environments to meet the strain imposed by IP distribution. 

A single direct-to-home broadcast requires two monitoring analyzers, with one located at each end of the transmission. A local broadcast system has the same requirement. In an IP environment the demands increase. Several devices, including one or more routers and switches, lie on the transport path from the signal's origin and its final destination in the viewer's receiver, Simpson wrote. The number of pass-through points means more opportunities for the video stream to become impaired or decrease in quality. Any one device could cause a quality drop, or the video could slowly diminish in quality through each successive device it passes through - therefore IPTV systems require monitoring at more intermediate points. 

Additionally, wrote Simpson, IPTV deliveries are generally single video transport streams transmitted individually through the network. The resulting fragmentation results in more individual streams that must be tested as more variables come into play.
