The VP771 is a highquality presentation switcher and scaler for a variety of signals. It accepts one of nine inputs: component video, DisplayPort (DP), 3G HDSDI, two computer graphics, two composite video and two HDMI signals. It scales the video, embeds the audio, and outputs the signal to one HDMI, one computer graphics, one 3G HDSDI and one DGKat TP, together with digital audio, unbalanced stereo and a 2x10watt amplified balanced stereo speaker output.

- K-IIT XLTM Picture-in-Picture Image Insertion Technology - Ultrastable pictureinpicture, pictureandpicture, and split screen capability. Any video source can be inserted into or positioned next to any other video source with full window positioning and sizing controls.
- Kramer's PixPerfectTM Scaling Technology - Kramer's precision pixel mapping and high quality scaling technology. Highquality 3:2 and 2:2 pull down deinterlacing and full up and down scaling of all video input signals.
- Ultra-Fast Fade-Thru-Black (FTBTM) Switching - Video switching transitions are clean and ultra fast. The video fades to black and the new input fades from black for smooth, glitchfree switching. The output signal provides constant sync so the display never glitches.
- Advanced Deinterlacing Functions - Method, sync, selectable film modes, diagonal correction and motion detection sensitivity, 3:2 and 2:2 pulldown; 24sf handling.
- HDTV Compatible.
- HDCP Compliant - The HDCP (High Definition Content Protection) license agreement allows copyprotected data on the HDMI input to pass only to the HDMI output.
- Multi-Standard Operation - SDI (SMPTE 259M and SMPTE 344M), HDSDI (SMPTE 292M) and 3G HDSDI (SMPTE 424M).
- Advanced Input and Output EDID Management.
- Mass Notification Emergency Communication System (MNEC) - Activates a national or campuswide notification, immediately displayed when an emergency situation develops. It uses automatic text overlaying, either via a crawler or a full screen cover up, as well as an optional audio alert.
- DGKatTM Signal Integration - Kramer's unique technology for converting TMDS as well as control and communication to signals that run over twisted pair cables. We strongly recommend using Kramer DGKatTM cables designed specifically for optimum performance.
