Mixed Signals provides the industry’s most granular frame-by-frame analysis of the MPEG transport stream and scalability to monitor hundreds of channels simultaneously.

Mixed Signals monitoring solutions perform deep inspection of every packet in real-time, simultaneously across hundreds of channels and programs. This provides visibility into video and audio quality metrics such as loss of video and audio, audio silence, video freeze, tiling, macro blocking, slow channel changing and application errors. Our deep packet analysis technology goes beyond traditional monitoring probes to obtain detailed reports on service degradation resulting from poor video and audio quality, MPEG data and table errors, packet arrival interval or delay factor, or from embedded data.

Detailed monitoring of single and multi-program transport streams includes historical uptime statistics, bandwidth trending, audio/video quality of experience metrics, and embedded data tracking and identification. The Sentry product line provides detailed table information along with comprehensive PID and program information.

With advanced alerting, instant notification is possible when problems occur using real-time, configurable alerts. Receive alerts based on various subscriber impacting events including video presence, frozen video, macroblocking, tiling, loss of audio and audio volume level issues; as well as various criteria relating to PIDs, tables, and discontinuities.

Network IP Statistics

Perform root cause analysis on the IP network by using built-in analysis tools and historical reporting to correlate IP anomalies with occurrences of other problems such as discontinuities, audio silence, video freeze alerts, etc. IP Statistics provides a historical graphical report on the entire IP video network that includes the types of issues and information on what the subscriber impact was for any network issue.


Advanced Reporting

Mixed Signals’ source to edge monitoring solution provides unprecedented insight and accuracy into the service quality at all locations, from the main and secondary headends, to hub sites. In addition, since these reports are all event based and actionable, service providers can identify and isolate the root cause of an issue in almost real time.


Video & Audio QoE (Quality of Experience

The Video and Audio Quality of Experience scores serve as an indication of the satisfaction level of the TV viewer.The scores are based on human perceptual analysis of hundreds of audio and video PIDs simultaneously in real time. Should issues such as temporarily frozen video, tiling/macro?blocking, audio disruptions, etc., affect the quality of the viewers’ TV viewing experience, the score is reduced.



With an expert team centered on developing best-in-class monitoring solutions, Mixed Signals constantly releases exciting new features that address the dynamic and changing requirements of today’s digital networks. M ixed Signals offers a full range of monitoring solutions to support even the most advanced digital networks. Our goal is to make cost-effective solutions and ensure our customers’ return on investment is significant.


Audio Level Monitoring

Monitoring and reporting on audio volume level issues helps providers address the common problem that exists with varying volume levels on different channels (evident when the viewer changes channels) or during commercial inserts. Mixed Signals audio level monitoring solution provides multichannel video service providers with the ability to monitor all of their programs and all of their channels in real time for any audio volume discrepancies.
