The ATSC Broadcast Monitoring systems monitor the OTA broadcast signals and the multi-program transport streams they deliver for signal or encoding anomalies. The systems provide 24\/7 coverage for monitored broadcasts. The Honolulu system is located on the Red Hill side of Moanalua Valley. As this is a challenging location, the Televes yagi is pointed at the Tripler side valley wall to obtain a reflected signal of Akupu towers.<\/p>\n
For a writeup about the charts in action see our blog entry at in-koherence.com<\/a>.<\/p>\n The monitoring system is an internal project of Koherence, LLC <\/a>and based on the Project Entangle<\/a> platform.<\/p>\n The monitoring systems upload data to the HNLATSC servers periodically (currently every 5 minutes), where it is used to create various charts and reports.<\/p>\n For more information on the charts and reports generated by the monitor, please see:<\/p>\n If you’d like to understand where various statistics are generated as the MPTS flows through the monitor, then please see About: Statistics Generation<\/a>.<\/p>\n In addition to generating statistics about the signal and transport stream, the monitors record the full MPTS of each broadcast. The amount of MPTS stored varies by monitor – a day’s worth of MPTS for one RF channel is about 210 GB. A system monitoring 8 channels and having 16 TB of storage holds the last 9 days’ or so worth of broadcast.<\/p>\n The MPTS is not available for download, however if you have a need for it (or would like us to examine it for some property) please get in touch with us via the Contact <\/a>page or email<\/a>.<\/p>\n If you would like to bookmark the chart or report for a specific broadcast, you can do so using query parameters with the charts launch pages. The launch page for ATSC 1.0 is https:\/\/hnlatsc.koherence.com\/index.php\/atsc-3-0-broadcast-monitor-launch. It accepts the parameters “bmon_channel=XX” where XX specifies an RF channel and “bmon_chart=YY” where YY is one of Tuner (RF and Demodulation chart), PSIP, MPTS, or Program (Program & Bitrates chart). For example, to bookmark the tuner\/demodulator chart for RF 35, bookmark the URL:<\/p>\n For the ATSC 3.0 charts the launch URL is https:\/\/hnlatsc.koherence.com\/index.php\/atsc-3-0-broadcast-monitor-launch. It also accepts “bmon_channel” for specifying the RF channel of interest, and “bmon_chart” can have the values Tuner, PLP, Service, or Signaling.<\/p>\n The monitors need to be taken down periodically for software\/hardware updates, and as with all software and hardware experiences failures from time to time. We’ll try to keep a log of downtime on the Maintenance History<\/a> page so you’ll know why there’s a hole in the charts or reports.<\/p>\n Like the base Project Entangle platform its based on, the monitoring system undergoes constant improvement. If you have a feature request we’d love to hear about it.<\/p>\n And if you run into a problem with the monitoring system, please send us a message via the Contact<\/a> page or drop us an email<\/a>.<\/p>\n (And if you have an idea for a name other than “the ATSC monitoring system” please drop us a note too!)<\/p>\n And as always, keep watching OTA and supporting your local broadcasters!<\/p>\n","protected":false},"excerpt":{"rendered":" The ATSC Broadcast Monitoring systems monitor the OTA broadcast signals and the multi-program transport streams they deliver for signal or encoding anomalies.
