VP-794 is a high-performance switcher/scaler/scan converter for analog and digital video signals developed specifically for driving large screen displays and multiple screen applications from video or graphics sources.
It up- or down-scales the incoming signal, processes the image with HQV and flexible warping, geometry correction and professional grade edge blending and outputs the signal to 3G HD-SDI, DVI/HDMI, VGA and S/PDIF connectors.
VP-794 includes a special mode for driving LED video walls with pixel-accurate output image sizing.
VP-794 is multi-personality; it can be switched between LED, Projection or Scaler/Scan Converter modes, greatly appealing to rental and staging providers as it permits a single model to be held in an inventory.
VP-794 is based on Calibre UK's HQView architecture optimized for low latency scaling to arbitrary active image sizes. VP-794 features powerful dual-processor architecture with 16-bit professional-grade blend processing with de-gamma, post-warp blending for optimal blend and warp performance and curved screen warping. VP-794 can capture a live image for display as a still, for example a customer logo screen or backdrop. Unlike other scalers available in the market, VP-794 can scale, warp and blend this captured image, which is a valuable benefit for LED & Projection displays.
Offering the industry's best image calibration and flexibility, VP-794 offers per input channel RGB, Bri/Con/Saturation/Hue controls, including on digital and computer graphics inputs. This is an important feature for color matching images and displays on-set.
VP-794 video inputs include HDMI, DVI, VGA, Component, Composite, YC/SVideo and 3G-SDI inputs and Separate Genlock. Audio pass-through and de-embed is achieved from 3G-SDI & HDMI to 3G-SDI, HDMI & SPDIF.
VP-794 has a Built-in Test Pattern Generator including SMPTE Bars, Pluge, Aspect Ratio Test, Greyscale as well as custom downloadable test patterns that are accessible via web browser interface. With ease of use in mind, the rack-mountable VP-794 has front panel LCD menu with a jog-shuttle wheel for fast setup.
Remote control over a network takes advantage of an inbuilt web-server.
Designed with the application in mind In projection environments, VP-794 can be used for scaling, edge blending, warping, geometry correction and color correction.
For use with flat panel displays, VP-794 performs outstanding scaling and switching, scan conversion, rotation, portrait mode and color correction.
For video wall display, VP-794 performs vital functions such as down-scaling, pixel accurate sizing, arbitrary image size and color correction. VP-794 has a dedicated LED video-wall processing mode with ultra-easy to configure output window sizing using 'drag and drop' and automatic pan/tilt/zoom adjusting to the fit LED video-wall, which remains correct even if the input resolution or channel is changed.
