High-speed 4K scaler-switchers from Calibre's HQUltra range incorporate in-house developed virtual-ASIC video processing technology, providing the 'world’s fastest' single channel 4K presentation switching performance. The switches are set to revolutionise the current landscape of video displays.

Under the Calibre-Kramer ‘Powered by Calibre’ partnership, the HQView625 scaler-switcher is also available as Kramer VP-796. The global launch will take place at the Kramer Electronics booth (3443) during InfoComm in June.

Whilst competing technologies can switch in 2 or 3 seconds, HQUltra switches can switch between input channels in just 0.25 seconds, even with different input resolutions and formats and between different HDMI/HDCP inputs. With the devices, image black time when switching is only 0.1 seconds.

The HQView625/Kramer VP-796 supports 4K and has eight video inputs, including HDMI, Display Port, HDBaseT, VGA, Composite and DVI-U. Outputs include HDBaseT and two HDMI 2.0 outputs.

The more powerful HQView770/Kramer VP-798 includes pixel-accurate extreme downscaling for LED videowalls. As part of the HQUltra range, the device includes an extremely powerful LED-optimised scaling algorithm developed in-house by Calibre. Optimum performance features include advanced image warp and blend capabilities. The switch features 10 video inputs and four identical video outputs, including HDMI 2.0, HDBaseT and 3G HD-SDI.
