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 de­interlacing and full up and down scaling of all video input signals

 State-of-the-art video processing technology, with the highest quality de-

interlacing, noise reduction, and scaling performance for both standard­definition and high-definition signals

 K-IIT XL™ Picture-in-Picture Image Insertion Technology - Ultra stable

picture−in−picture, picture−and−picture and split screen capability, or fully

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
up, as well as an optional audio alert

 Port tunneling, bidirectional RS-232 interface – simple control commands

and data can flow in both directions from a controller to the VP-770 via the
Ethernet, allowing status requests and control of the destination unit

VP-770 – Overview

7

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.

i

3.1 HDCP Compliance

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.

6 The OSD Menu

The VP-770 OSD menu lets you set the operation parameters for the:

 Main Window Control
 PIP Window Control
 Entire System Control

The nature of the operation setup appears in the OSD title, as shown in the
example in Section 6.1:

 The title line shows the control mode (Main, PIP or Entire system)
 Level 1 lists the main menu items
 Level 2 includes the second hierarchy level, below level 1
 Level 3 includes the third hierarchy level, below level 2
 Function, is the selectable parameter or numerical value and can appear

either under level 2 or 3

6.1 OSD Menu Operation Example

In the example illustrated below, the Master Connection is set to DGKat (see

Section 6.7).

The table below shows function 632 (from the Protocol in Section 12.2):

 6 in the hundreds, represents “Scale” which is the 6th menu item in the main

menu list

 3 in the tens, represents “Output” which is 3rd in the Scale menu
 2 in the units, represents “Master Connection” which is second in the Output

menu

18

VP-770 - The OSD Menu

The subtitle, below the title line shows
the current level accessed (Scale in this
example)

After selecting Output (which is the
second Level), it appears in the subtitle

Once Master Connection is selected, the

Title changes to “Entire System Control”

indicating that the selection will affect the
entire system. The subtitle shows the
current, Level 3, selection and the menu
list shows the function (DGKat)
Note that SDI is not applicable to the
VP-770 and appears transparent.
If the transparency of the OSD menu is
set to ON this menu item will become
invisible (see Section 6.8)

If the display layout includes a PiP window, you can set the OSD menu to control
the main source window and the PIP window separately (by defining Window
Control).

General characteristics which apply to the entire system (for example, setting the
volume) are changed without needing to shift control (the title line will state: Entire
System Control).
