All Bridge Technologies probes have OTT/ABR capabilities relevant when monitoring in adaptive bitrate streaming systems. The technology comes in the form of OTT engines. For VB120/VB220 the total number of OTT streams that can be monitored is 250 (25 engines). For VB330 the figure is 500 (50 engines).
Formats supported include HLS, HDS SmoothStream and MPEG-DASH. This enables providers to have real active monitoring of ALL channels provided both for LIVE content and selected VoD streams.
Each OTT Engine operates autonomously and only requires knowledge of the URL from which the media is being fetched. The OTT Engine then parses the manifest file provided by the origin or edge-server, extract the different profiles served, validates syntax, checks chunk counters and then does the same for the individual profiles.
Support for AES-based decryption is included as well as an innovative method for customizing the expected format of the manifest files received.
