Calibre to unveil 4K Scaler/Switcher at Prolight + Sound 2019

Calibre will debut the first models in its HQPro series, the HQPro1000 4K/UltraHD scaler/switcher and HQPro1050 remote controller, when it exhibits at Prolight + Sound in Frankfurt, Germany.

At the exhibition that runs April 2 to 5 at the Messe Frankfurt, Calibre will show the HQPro1000 that is designed for pro AV and LED large venue applications. It features a modular architecture composed of the base unit, two optional input cards and one optional output card. 

The base unit includes two 4K HDMI 2.0 inputs, one 4K HDMI 2.0 output and a confidence monitor output and genlock connectors.

Calibre’s initial release also includes an input card featuring a 4K HDMI 2.0, 4K Display Port 1.2 and 3G-SDI interfaces to expand the number of supported sources. The initial release also includes a card with four 2K HDMI 1.4 outputs allowing for splicing up-to four LED walls. Future releases will include 12G-SDI and HDBT input and output cards. 

The HQPro1000 supports four layers that can be sized, positioned and mixed anywhere on the output display. Switching is achieved through seamless transitions, cuts or ultra-fast switching. Scaling is provided by Calibre’s low-latency proprietary HQUltra technology supporting 4K50/60 4:4:4 RGB formats. Additional features include vertical and horizontal flips, support for input area-of-interest (AOI), EDID and HDCP management, freeze and full colour control. A future software release will add support for streaming video using the H.264 codec.

Ten presets are also included, allowing users to store and recall different screen layouts. Each preset stores the source, size and position, and all other attributes associated with each layer. The size, position and priority of all layers stored in each preset can be previewed on the front panel’s colour graphic display in a wireframe format. 

Calibre will also introduce the HQPro1050, a dedicated remote controller for the Calibre control unit HQPro1000. The HQPro1050 communicates with the main unit via the LAN interface and allows control of the unit from a remote location. 

Users can also control the unit from the front panel, computers or mobile devices via the built-in webpage interface and soon to be released set of API commands.
