Tektronix, an industry-leading innovator of video quality monitoring solutions, has unlocked end-to-end ABR monitoring with the unveiling of decryption and decode functionality for the Sentry ABR video quality monitoring platform.

Adaptive bitrate streaming (ABR) is the underlying technology used with multiscreen, on-demand streaming services for PCs, laptops, smartphones, tablets and TVs. Also called TV Everywhere or OTT (over the top), multiscreen video services use ABR to break content into small fragments of compressed content for transmission to viewing devices. With the increased amount of content delivered via ABR, service providers need to be able to pinpoint errors in the network quickly to reduce operational expenses related to trouble calls and mean time to detect and repair (MTTD, MTTR) issues.

Tektronix Sentry products are widely deployed and are used to provide vital QoE (Quality of Experience) and PVQ (Perceptual Video Quality) information to network operators concerned about the experience they are providing their customers. With the addition of decryption and decode functionality, Sentry ABR gives service providers the breadth and depth of monitoring they are accustomed to with linear-based services. 

After transcoding in a typical ABR workflow, a video stream is fragmented into fixed time duration fragments, encrypted and Digital Rights Management (DRM) applied. Sentry ABR is now capable of viewing this encrypted content to evaluate the actual viewing experience, or QoE as well as determining PVQ.

Sentry will be on show at the TekInsite booth at ABE2016.
