The VP−790 is a high−quality presentation scaler/switcher for RGB component, computer graphics, composite, s−Video, HDMI, DVI and 3G HD−SDI signals. The unit takes one of the inputs, scales the video, embeds the audio and outputs the signal to the computer graphics, DVI/HDMI and 3G HD−SDI outputs simultaneously.

  • HQV® Video Processing — HQV (Hollywood Quality Video) processing represents the state–of–the–art in video processing technology, with the highest quality de–interlacing (with 3:2 & 2:2 pull down), noise reduction, and scaling performance for both standard–definition and high–definition signals.
  • Max. Data Rate — 3Gbps (3G HD–SDI).
  • HDTV Compatible.
  • HDCP Compliant — The HDCP (High Definition Content Protection) license agreement allows copy–protected data on the HDMI input to pass only to the HDMI output.
  • Multi–Standard Operation — SDI (SMPTE 259M and SMPTE 344M), HD–SDI (SMPTE 292M) and 3G HD–SDI (SMPTE 424M).
  • Video Warping — Uses user–generated screen coordinates to match any linear or non–linear surface.
  • Edge Blending — Facilitates building large images using multiple projectors by feathering the overlapped edges.
