Broadcast Probing System

Cloud-based monitoring of DVB-T/T2 networks​​

Digital service broadcast suffers from misconfigurations at the source and dynamically changing signal propagation conditions. The lack of feedback leads to undisclosed service degradation and decreased experience. Our Broadcast Probing System offers cloud-based continuous near real-time monitoring of broadcast networks by utilizing massively distributed low-cost probes. Controlled either individually or in groups the probes are securely instructed to execute scheduled jobs like scanning, tuning and transport stream inspection. The collected spatiotemporal data links RF characteristics and stream quality, multiplexed tables (e.g. AIT/HbbTV, EIT/EPG) and AV dumps to allow for live analysis, evaluation and integration into monitoring environments.
