Tektronix's PRISM upgrade allows DPs and operators to setup cameras for live HDR.
At the upcoming 2018 NAB Show, Tektronix will showcase the latest solutions to ensure video and audio content quality, signal integrity and regulatory compliance, as the TV industry transitions to next generation networks, workflows, and delivery systems.
The focus of the Tektronix 2018 NAB Show exhibit is demonstrating and explaining the latest advances in Hybrid IP and SDI media analysis, 4K/UHD with HDR and WCG monitoring solutions, and Quality Assurance in a virtual or cloud environment.
Tektronix flagship PRISM is a real-time IP/SDI monitoring and analysis platform designed specifically to generate objective, trusted information for production of content to satisfy growing expectations in quality and consistency. It is designed to isolate and seamlessly remedy Hybrid IP and SDI workflow issues on daily basis. It offers broadcast engineers and IT professionals connectivity, monitoring and analysis for ST 2110 (-20 (video), -30 (audio) and -40 (metadata)), ST 2022-6 and ST 2022-7.
In addition to the new ST 2110 capability, Tektronix has extended its Precision Time Protocol (PTP) timing analysis to include ST2022-7 timing for system setup and maintenance. PRISM can perform IP and SDI (12G/3G/HD/SD) measurements and offers simple ways to switch between either type of input.
A Tektronix SPG8000A master sync and PTP grandmaster clock generator will provide PTP support for the hybrid IP and SDI media infrastructure in the exhibit. A pair of SPG8000As with the Tektronix ECO8000 series of change over units is a highly reliable timing solution for both IP and SDI networks.
HDR and WCG Upgrade
4K/UHD, High Dynamic Range (HDR) content and Wide Color Gamut (WCG) are becoming increasingly important. The PRISM platform enables shaders and operators to setup cameras for Live HDR using a proprietary STOP waveform and automated conversion support for a wide selection of camera log curves adopted by various camera manufacturers including S-Log, S-Log 2, S-Log 3, C-Log and Log-C.
PRISM also supports both SMPTE ST 2084 standard and Hybrid Log Gamma (HLG) as per the ARIB ST B-67 standard. In post-production, colorists and editors can easily master their content to different standards and across different color spaces such as REC 709, ST 2020 using familiar Tektronix measurement tools regardless of content type.
These HDR capabilities can easily be added to existing WFM/WVR8000 and WFM5200 series products with the purchase of Option PROD (a field upgradeable software-only option). Customers with valid software option key license for PROD can upgrade their instruments free-of-charge with the new firmware that can be downloaded from the Tektronix website.
Tektronix Aurora file-based QC tools and Sentry monitoring tools now provide the visibility and control needed by content providers in virtual and cloud environments. Sentry is the scalable monitoring solution that can measure the Quality of Experience (QoE) experienced by viewers. These measurements look at the actual content being provided to ensure there are no major quality issues (blocking, audio drop out, frozen frames) and that the content meets regulatory compliance requirements (SCTE35 Type testing, Closed Caption and Loudness testing). With Digital Rights Management (DRM) support, Sentry ABR can decrypt each program applying DRM and can view and report on the content seen by subscribers.
Aurora, which supports the latest IMF standards and has expanded AWS workflow compatibility and S3 storage support, can be set up to automatically perform a wide range of fundamental content quality tests including TekMOS picture quality, video analysis, and format compliance.
TekMOS is a non-reference picture quality analysis algorithm that provides a Mean Opinion Score (MOS) that has a high correlation to how viewers would rate the quality of the content. Using graphical displays, TekMOS provides actionable reason codes for quality measurements enabling providers to take corrective action. EBP measurements will ensure that switches between streamed profiles will be seamless and not impact the viewers quality of experience.
Aurora and Sentry have been used in environments with millions of hours of both live and file-based content. They are proven solutions that can be used as cloud or virtual machine implementations and give content providers true visibility into content quality.
