Lawo’s HOME Downstream Keyer allows operators to move 3 layers up

Lawo has introduced HOME Downstream Keyer, a “sophisticated and powerful” HOME App for video. Its feature set, says Lawo, is closer to what a vision mixer provides than to what operators expect from a downstream keying function of the past.

John Carter, Senior Product Manager, Media Infrastructure, Lawo, said, “HOME Downstream Keyer allows operators to simultaneously and independently transition up to three key layers over an A/B background mix. 

“As Lawo’s first mixing processing app, it comes with eight ST2110-20 receivers and two ST2110-20 transmitters. Each of the three Keyers can perform Luma, Linear or Self keying to provide the desired processing for high-end broadcast graphics designed with transparency and drop shadows.”

The HOME Downstream Keyer app provides keying and mixing capabilities to meet production needs and enable additional channel branding within a state-of-the-art, agile infrastructure, based on triggers issued via the VSM control system where desired.

As part of the HOME Apps suite, HOME Downstream Keyer can be deployed in both standard dynamic range (SDR) and high dynamic range (HDR) workflows. It supports SMPTE ST2110 (including JPEG XS), NDI, SRT, and in a future version, Dante AV transport as required.

Like all HOME Apps, and a growing number of other Lawo solutions, HOME Downstream Keyer can either be licensed perpetually or solicited on an ad-hoc basis through Lawo Flex Subscription credits.

Jeremy Courtney, Senior Director, CTO Office, Lawo, concluded, “With HOME Downstream Keyer, Lawo’s HOME Apps have reached a new level of sophistication.

“Architecting the container-based HOME Apps platform from scratch for bare-metal compute has allowed Lawo’s software developers to avoid the pitfalls and limitations of lifting and shifting existing technology to a different platform.

“The advantages of this clean-slate microservice approach are now becoming apparent.”
