Q. can you explain how orion-ott works? A typical scenario would be ORION-OTT running at the post origin server point in the workflow. Based on user defined automated or manual schedules, it looks at every asset to check for errors and generates alerts and reports in real time. It will also check for inconsistencies pertaining to ABR package compliance, manifest/playlist syntax, download errors, audio video quality, etc. User can get in-depth reports regarding errors, which can be used to troubleshoot problematic issues. The web-based interface of ORION-OTT allows remote monitoring through any browser-enabled device, giving users a comprehensive monitoring and reporting tool at their fingertips. Q. what types of checks are essential for abr content delivery? Video service providers will want to look for baseband quality; compression artefacts such as macroblocking, pixelation, ringing artifacts, etc.; and standards compliance checks. Then there are ABR checks such as segment start time, alignment of variants, consistency between metadata and actual content, etc. It is also important to make sure that the monitoring tools support a wide variety of formats such as Apple HLS, DASH, SmoothStreaming, H.264, Closed Captions, etc. Q. can ott monitoring solutions be used for both real-time and vod/ linear environments? Yes, in fact a good OTT monitoring solution should support real-time, VOD, and linear workflows. They can be quite effective for post-origin server, content delivery network (CDN), and cache server monitoring where QoS checks such as availability of URLs, download time, and latency checks are more important. At the post-origin server, CDN, and edge server locations, broadcasters will want to focus more on HTTP checks. Having a high-density, high-performance monitoring platform will ensure proactive monitoring of large volumes of content. Q. what kind of problems should an ott monitoring solution address at the content delivery stage? During the content delivery stage, you need a solution that checks for availability of content and comprehensive HTTP checks such as content download time, latency, etc. These checks fall under the category of QoS assurance, and are deemed critical for OTT delivery. Basic quality checks such as freeze frames, black frames, etc. should also be part of the monitoring at this stage. Audio checks such as loudness, silence, and levels are also important. In an OTT workflow, content is stored on origin servers, CDNs, as well as edge/ cache servers. Depending on the location of the end user, bandwidth availability, and other factors, video is sent from one of these servers to the end user. QoS problems can arise at any of these delivery points, and content providers will need visibility into the entire workflow to ensure optimum QoS and QoE. ORION-OTT helps address these critical OTT delivery requirements through centralized management, checks of QoS and QoE, and real-time error alerts for problem detection and troubleshooting.
