Tektronix Introduces OTT Monitoring Solution

News Image
Tektronix has introduced video on demand (VOD) and live over-the-top (OTT) monitoring solutions for customers.

At IBC2017, Stand 10.D14, Tektronix will showcase the new solutions designed with scalability in mind. As a result, broadcasters can start out at any level that fits their needs, whether a single point in the video workflow or part of a wider, more comprehensive monitoring program.

The Tektronix OTT monitoring solution for live content, based on the Sentry platform, provides monitoring and diagnostics anywhere along a modern media workflow, from cloud ingest through to content delivery networks (CDNs). With new support for Microsoft's PlayReady digital rights management (DRM) technology, Sentry offers video quality of experience and picture quality analysis on encrypted networks. The software-based solution can be deployed where it's needed with cloud, virtual private network and datacenter options.

For file-based analysis, the company's Aurora file-based QC solution delivers flexibility and scalability. With Aurora, broadcasters can verify the correct encoding for all ABR profiles, and ensure their packaging is error-free and aligned for the viewing experience. They can also use Aurora's perceptual video quality tests to reveal any encoding issues and alignment features ensure seamless transitions between different representations for viewers.

Charlie Dunn, General Manager, Video Product Line, Tektronix, said: "With so many fundamental changes in technology and workflows, broadcasters need scalable, future-proof and highly flexible monitoring solutions to adopt cloud-based OTT video delivery models that ensures quality and regulatory compliance. For both file and live OTT, our scalable solutions allow customers to start out at any level, big or small, and to see what their viewers see with QoE and video quality measurement that validate picture quality."

Also being demonstrated for the first time at IBC will be Tektronix's TekMOS technology. TekMOS provides a new, fully automated single-ended mean opinion score evaluation system for picture quality. As a single-ended analysis solution, TekMOS uses machine-learning techniques to evaluate picture quality and identify distortions based on a large training set of subjectively graded images. The score-based approach saves broadcasters time and money since they no longer need to devote resources to monitoring picture quality and greatly improves the viewers' experience.

As opposed to an implied image quality measurement approach, TekMOS provides an objective measure of picture quality so broadcasters can comparatively grade picture quality through their broadcast chain. With TekMOS, broadcasters can ensure image quality stays consistent throughout the workflow and any problem areas can be quickly identified and corrected based on the actionable scores it provides.
