VP-770 - Overview
3 Overview
The Kramer VP-770 is a high quality presentation switcher and scaler. It accepts
one of eight inputs: a component video on RCA connectors, a DisplayPort (DP)
signal on a DisplayPort connector, two computer graphics signals on 15-pin HD
connectors, two composite video signals on RCA connectors, and two HDMI signals
on HDMI connectors. It scales the video, embeds the audio, and simultaneously
outputs the signal to an HDMI output, to a computer graphics output and to a
DGKat TP output, together with a digital audio output and an unbalanced stereo
audio output.
COMPONENT VIDEO is also known as Y, Pb, Pr, or Y, Cb, Cr or YUV; compatible with both
SD and HD component
The VP-770 Presentation Switcher / Scaler features:
PixPerfect™Scaling Technology –Kramer’s precision pixel mapping and high
quality scaling technology. High-quality 3:2 and 2:2 pull down de-interlacing

customizable windows’size and position control: any source can be inserted
into or positioned next to any other source and resized as desired
Ultra-Fast Fade-Thru-Black (FTB™) Switching - Video switching transitions
are clean and ultra-fast. The video fades to black and the new input fades
from black for smooth, glitch-free switching. The output signal provides
constant sync so the display never glitches
An emergency alert system that can have a national or campus-wide
notification immediately displayed when an emergency situation develops, by
means of automatic text overlaying, either via a crawler or a full screen cover

VP-770 – Overview

3.1 HDCP Compliance
If an HDMI signal is HDCP protected, it can only appear on HDMI
and DGKat outputs that are connected to HDCP compliant displays.
The VP-770 will not output an HDCP protected source to a display
that is not HDCP compliant. Instead it will show a black screen.
In the dual window display mode (see Section 7.2), even if only one
of the inputs is HDCP protected, and is output to a non-compliant
display, it will affect the entire screen and turn it black.
3.2 About the Power Connect™ Feature
The VP-770 can power the receiver on the DGKat output when the devices are
within 90m (270ft) of each other. The Power Connect™ feature applies as long as
the cable can carry power and the distance does not exceed 90m on standard TP
cable. For longer distances, heavy gauge cable should be used (TP cable is still
suitable for the video/audio transmission, but not for feeding the power at these
distances).
3.3 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built cables significantly outperform
regular CAT 5 / CAT 6 / CAT 7a cables.
