The Q Check IP head end is a professional multi-stream viewing and analysis tool. It is designed to monitor and analyze streams at headends and teleports or wherever many streams are brought together for distribution.
Digital transport streams are specialized MPEG-2 or H.264 streams with features necessary to enable them to run on any MPEG-2 or H.264 decoder.
Transport streams are used throughout the world in the delivery of satellite based distribution of content by most of the world’s content delivery networks. There is a huge value attributed to this content. It must be delivered reliably 24 hours a day and there is no room for failure.
A remote, 24 x 7 monitoring system designed for verifying the quality of digital audio and video services delivered over IP networks. Combines multi-window MPEG-2 or H.264 transport stream monitoring, comprehensive TS analysis, error logging and alarms, and TS recording in a single or multicore Intel® Xeon® based windows system. Detects and logs errors such as video freezes, black screens, loss of video, audio, or subtitles. Very scalable for 10, 20, 30, or 50+ Services or Network-Wide Monitoring. Includes support for audio alarms, SNMP, Email Alerts, etc. Supports ATSC Tables.
