New PRISM capabilities will be on display in the Tektronix exhibit.
Engineering, IT and Operations teams responsible for the delivery of high quality content will require new tools and solutions that are optimal in a hybrid IP and SDI environment. At the 2017 NAB Show, Tektronix will showcase end-to-end solutions that ensure content quality, signal integrity, and regulatory compliance in both.
The Tektronix exhibit is planned to demonstrate and explain the latest technology in scientific signal test, measurement and analysis tools to visitors. Scientific measurement is crucial to validate and ensure the best video, audio, or data content. Knowing how the network and the associated operations are performing at the local station and group level is vital.
Tektronix was at the leading edge of TV signal testing and measurement when the National Association of Radio Broadcasters (NARB) became the National Association of Radio and Television Broadcasters (NARTB) in 1951. The company continues to provide innovative tools to help broadcasters measure and monitor electrical signals to comply with industry technical standards and legal requirements.
New tools and solutions
New at the 2017 NAB Show will be additions to the Tektrtonix PRISM capabilities. They include analysis of PTP synchronization timing, and support SMPTE ST 2022-7 redundancy and Internet Group Management Protocol (IMGP) V3 for IP multicasting. A new API provides easy system integration into network management systems, and it includes IP stream capture for deep dive analysis.
Availability and quality of both live and file-based content is a critical task for content distributors moving to adaptive bit rate (ABR) delivery models. Tektronix’ Sentry ABR and Aurora file-based QC solutions provide Perceptual Video Quality (PVQ) measurements designed to detect video compression artifacts that affect the viewer’s quality of experience. PVQ is a proven technology that provides an accurate measure of quality that is based on years of real-world evaluation. This offers content distributors a tight correlation between file-based and live stream monitoring technologies.
In addition to PVQ, the Sentry ABR also provides an end-to-end view of the Quality of Experience (QoE) for all profiles by decrypting and decoding the live video and audio from the origin or caching servers for both encrypted and unencrypted content. With Digital Rights Management (DRM) support, Sentry ABR can decrypt each program from servers applying DRM and can view and report on the same content seen by subscribers.
Tektronix WFM8000 series 4K HDR waveform monitors enable the technically accurate creation of 4K HDR content from content acquisition to color grading or correction in post, ensuring the highest level of content image quality.
HDR features include graticules specifically designed for 18% grey (20NITS) and 90% reflective white (100NITS) for easy adjustments to correct grey and white points of content which is essential in HDR applications. Other HDR capabilities include support for both SMPTE ST 2084 standard and Hybrid Log Gamma (HLG) as per the ARIB ST B-67 standard and 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.
The new HDR capabilities can easily be added to existing WFM/WVR8000 series products with the purchase of the field upgradeable software-only Option PROD.
A fundamental requirement of a hybrid IP and SDI infrastructure is the ability to synchronize the facility in a mixed packet and frame-accurate environment. The Tektronix SPG8000A master sync and PTP grandmaster clock generator will be on display in the exhibit. It will demonstrate SPG8000A Precision Time Protocol (PTP) support for hybrid IP and SDI media infrastructures with PRISM showing detailed PTP timing measurement and analysis for system setup and maintenance.
