IPTV Testing with the IQS-8510B
The IQS-8510B module equipped with the IPTV option can be used at
different points in the network to collect data and help isolate a fault
affecting the IPTV service quality as described in the figure below.
While monitoring the selected stream (via its IP address) in the IPTV
network, all the functions supported via the Frame Analyzer application
are also simultaneously available. This provides additional resources
facilitating the troubleshooting of network issues that could provide an
insight to IPTV detected problems.
