A New Software Update to Telestream PRISM


A company known for its file-based media workflow orchestration, media streaming and delivery technologies is unveiling a new software update for its PRISM series of hybrid SDI and IP waveform monitors.

The latest update from California-based Telestream supports more advanced tools for HDR (High Dynamic Range) and WCG (Wide Color Gamut) productions in 4K and HD. While PRISM has been used by customers making the transition to IP-infrastructures, this software release makes it a tool in 3G and 4K Production applications for SDI.

This software upgrade is available now for any model of PRISM with the production license to enable the features that support HDR and WCG.

“We’ve been working closely with customers who are producing live events and creating content masters in post-production to understand how we can help them simplify their workflow,” said Ian Valentine, VP of products and strategy for the Tektronix Video Business unit at Telestream. “The result of this close work is a complete toolset that includes solutions for HLG, PQ, and Dolby Vision events and projects.”

This new toolset not only includes additions like CIE Chart, False Color, and STOP Waveform
(a new kind of waveform that displays in units of lights as a log scale), but it also includes more familiar tools like Diamond, Vector and a standard % waveform—easing the learning curve when transitioning to these formats.

“Working in HDR and an expanded color space is new for everyone, but ultimately these
challenges will demand a new workflow and we have a role to play to support the industry,” said Tsuyoshi Kitagawa, Product Manager at Telestream.

As an example, the new software update includes a false color mode that can highlight the area in the picture display where the colors have exceeded the P3 gamut range which is critical in grading and QC’ing projects for Netflix requirements. Other questions that customers have asked such as “what % of the picture is in the HDR range” (i.e. above 203 NITS) are now solved with objective tools that display this information or can clearly show this in a customizable false color mode.

The PRISM platform is a next generation family extension to the broad range of waveform
monitors that Tektronix Video—now a business unit of Telestream—has developed to aid in
similar transitions from Analog to Digital and from SD to HD.
