iControl Loudness Monitoring

Aggregation and Analysis of Loudness Data Over Network

iControl Loudness Monitoring stores loudness data collected across various signal distribution networks. It enables broadcasters and pay-TV operators to guarantee end-user Quality of Experience while remaining compliant with loudness legislation around the world, including the CALM Act (U.S.). Leveraging segment information provided by iTX or any third-party automation system, loudness data can be plotted in a meaningful way, enabling rapid troubleshooting and identification of problematic sequences. The application generates complete reports for compliance purposes.
