VP-774A – Getting Started 3

3 Overview

The Kramer VP-774A is a high quality presentation switcher and scaler. It accepts

one of nine inputs: an SDI signal on a BNC connector, a DisplayPort (DP) signal on
a DisplayPort connector, one composi t e video signal on an RCA connector, two
computer graphics signals on 15-pin HD connectors, and four HDMI signals on
HDMI connectors. It scales the video, embeds the audio, and simultaneously outputs
the signal as follows: to two HDMI outputs, to an SDI output and to an HDBaseT TP
output, together with a digital audio output and a balanced stereo audio output.

The VP-774A 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
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-774A via the
Ethernet, allowing status requests and control of the destination unit

• Advanced deinterlacing functions - including 3D comb filtering, film mode,

• 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

:

18 VP-774A - The OSD Menu

In the example illustrated below, the Master Connection is set to HDMI2 (see

Section 6.7

).

The table below shows function 632 (from the Protocol in Section 13.2):

• 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 3

rd

in the Scale menu

• 2 in the units, represents “Master Connection” which is second in the Output

menu

Scale (6) Output (3) Master Connection

(2)

HDMI1 0 632

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

After selecting Output ( whic h 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 (HDMI2)

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, see Section 6.8

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).

Note that:

• A selected parameter that turns gray becomes valid immediately. You can

press Enter at this point to save these parameter changes to the memory
immediately (the screen will display “Saving Data” for a split second).

• In any case, exiting the menu saves the parameter to the memory

• Data is saved per window and per input (to a dedicated input + window

memory), as applicable

The control buttons let you control the VP-774A

• MENU (or ) button to enter the menu, exit the menu, and when in the OSD

ws: the active channel is input as Group A,

CH1 and CH2.

Figure 20: Set the Output Volume Level

6.3.1 SDI Channeling

SDI channeling includes four groups with two stereo channels each. Two of the
groups are always connected and the other two disconnected. You can select (via
the OSD) one of the eight SDI embedded stereo audio channels, together with
three bypassed channels, to be routed to the input of a connected machine with
SDI audio channels (for example, the Kramer 6810HDXL SDI/HD−SDI/3G Audio
Embedder/De−embedder, or the Kramer 6809HD HD/SD-SDI AES Embedder).

Within the two connected groups, one channel can be activated and
the remaining three channels are bypassed. The acceptor device will
input the channels as follo
CH1; the bypassed channel in the same group is input as Group A,
CH2; the two remaining bypassed channels are input as Group B

30 VP-774A - The OSD Menu

In the example illustrated in Figure 21, channels C and D are disconnected and
channels A and B are connected (CH1 and CH2 in group A are bypassed, CH1 in
group B is bypassed and CH2 in group B is active).

These channels are input to the Kramer 6810HDXL, processed and output to an
audio acceptor:

• The group B active CH2 signal is input as Group A, CH1

• The group B bypassed CH1 signal is input as Group A CH2

• The group A bypassed CH1 signal is input as Group B CH1

• The Group A bypassed CH2 signal is input as Group B CH2

Figure 21: SDI Channeling Example

The active channel and bypassed channels are selected via the OSD menu.

Figure 22

shows the SDI Channeling menu:

Figure 22: The SDI Channeling Menu

In the OSD setup that is illustrated in Figure 23, CH 2 in group B (active), CH1 in
group B as well as CH 1 and CH2 in group A (bypassed) are routed via the
VP-774A SDI output to the input of 6810HDXL; groups C and D are disconnected
and therefore read as None (see example in

VP-774A - The OSD Menu 31

Figure 21).

Figure 23: SDI Channeling Example

If a different channel within the connected groups is activated, the remaining three
channels will be automatically routed to bypass.

If a channel in a disconnected group is activated, the system will automatically
rearrange the groups and channel assignments to keep two groups connected and
two others disconnected.

6.7.1 Selecting the Correct Aspect Ratio

You can configure the aspect ratio of any output image to fit your application. The
VP-774A offers four different aspect ratio settings: Follow Input, Follow Output, Best
Fit and Letterbox. Here is how each of these settings works.

FOLLOW INPUT – The aspect ratio and resolution of the

input video or graphics signal are both preserved (no
scaling). For example, a com p osite video image with a 4:3
aspect ratio will appear with the same aspect ratio on a
1080p (16:9) output image, surrounded by black bars

38 VP-774A - The OSD Menu

FOLLOW OUTPUT – The aspect ratio and res olu ti on

signal images

BEST FIT – This setting re-sizes the video or

either side.

LETTERBOX – This setting compresses the top and

of the input signal is re-sized to precisely match the
aspect ratio and resoluti on of the VP-774A output
signal. This may result in some distortion to the input

graphics input signal to “best fit” the output resolution
while maintaining the aspect ratio of the input signal.
For example, a composite video signal (4:3 aspect
ratio) will “best fit” to the top and bottom of a
widescreen output image, resulting in black pillars on

bottom edges of the input signal, but fills the width of
the screen. For exam pl e, to pr ese rv e a wides c re en
film image on a 4:3 display. When not using a 4:3
monitor, this mode is identical to Best Fit

6.7.2 Master Connection Settings

The Master Connection (HDMI1, HDMI2, HDBT or SDI) is usually set to the main
output display so that the optimal resolution for that display can be obtained.

By setting the output resolution to Native, the VP-774A is triggered to read the
EDID of the main display and change the output resolution value according to the
native resolution of the display.

Note that when the output resolution is set to Native:

• Selecting SDI as the Master Connection results in an output resolution of

720p @60

• If SDI is selected as the Master Connection, hot plugging the HDMI/HDBT

output will not change the output resolution

• If HDMI/HDBT is selected as the Master Connection, and a new display is

connected to the Master Connection output (hot plug), the VP-774A

6.8.1 The Luma Keying Feature

The luma keying feature is an easy-to-use method of compositing two video
sources into a single image. By setting up a “key” image or clip on a black
background, it can be merged – or overlaid – onto the primary video. The key
image is transparent in the areas of its dark background, resulting in a picture which
looks as if the key image is cut out and pasted over the primary image. This useful
function of combining images from two different sources is suitable for many
applications, such as sub-titling, labeling, advertising or logo insertion.

To apply the luma keying feature, first set the PiP window to the desired size and
location and then turn luma keying On. The PiP image will show without its
background.

).

The lower the luminance in the PIP window, the more transparent it becomes, thus
letting the main window image show. The higher the luminance, the less
transparent it becomes, not letting the main window show through. To use this
feature it is recommended to set the PIP image as follows: use low-luminance colors
for the background (the key image portion) and high-luminance colors for the logo.

For certain displays, the screen may flicker once for about a second
after activating or changing the luma keying setting.

We recommend that you activate luma keying after completing the
setup.

6.8.2 The Emergency Alert System

The Emergency Alert System (EAS) is a unique, versatile feature for immediate text
overlaying, with flexible options such as the inclusion of an audio alert siren and the
choice of displaying an emergency notification via either a text crawler or a text
window.

The EAS provides the ability to have a site-wide notification immediately displayed
when an emergency situation develops that could affect the health and welfare of
the people attending the site, whether that site is an educational facility, a corporate
site, a stadium or any other location where large groups of people come together.
Messages can include specifics about weather (tornadoes, hurricanes, high winds,
flooding, storms and so on), Amber and Silver alerts, safety and security, and also
general advisories.

Emergency alert messages are composed and transmitted using the Common Alert
Protocol (CAP). CAP is an XML-based application that allows a warning message
to be consistently disseminated simultaneously over many warning systems to
many proprietary applications and devices. By using XML, messages can be
composed, transmitted, and received across a broad range of proprietary AV and
other devices.

Generally, CAP format alerts can also trigger secondary functions, such as alert
tones, horns, buzzers, and sirens. They can be used to switch on AV equipment to
display alerts. The system also complies with the Emergency Alert System (EAS)
standard, an official, national warning system in the United States, which works in
coordination with the Federal Emergency Management Agency (FEMA) and a
number of US national emergency agencies.

For more details on CAP, go to https://www.oasis-

open.org/committees/download.php/6334/oasis-200402-cap-core-

The VP-774A intercepts XML files over the Ethernet in the CAP format via the
dedicated EAS port from the alert generator server (for example, a FEMA server or a
proprietary CAP message generation application) for immediate alert message
triggering.

VP-774A - The OSD Menu 43

Figure 30: XML File Transfer

The position of the displayed CAP message depends on the severity of the alert.
Noticeable messages with “Extreme” and “Severe” headers will appear on the
screen and cover up any other content together with an audio alert siren (in case of
an Extreme level alert). Messages with lower levels of severity will appear as a text
crawler along the bottom of the image. When an alert is activated, the system (via
P3K) outputs messages according to the activation mode type (see Section 13.4

).

Figure 31: Emergency Alert System Display

The Expiration Date field of the CAP XML file determines when the message will
expire. Note that you can remove the message sooner by pressing/clicking any of the
buttons on the VP-774A (front panel or remote control buttons, as well as via the Web
page or protocol commands).

Press the Swap Inputs button to swap between MAIN and PIP inputs. For
example, if the MAIN window displays input 3 and the PIP window displays input 1,
these inputs swap places when clicking the Swap Inputs button, so the MAIN
window will now show HDMI 1 and the PIP window will show HDMI 3

9.1.3 Auto Switching

Click the Auto Switching button to open the Auto Switching window (see Figure 49).
The Auto Switching window lets you set the Main and PiP scanning mode
separately to:

• Off to disable scanning

• Scan mode to scan through the inputs in search of a valid input signal.

In the scan mode you can select which of the inputs will be included in the
scan (see Figure 50

) and also change the order of the scanned inputs (see

Figure 51)

• Last Connected mode to immediately switch to the latest valid input signal

connected (for HDMI and DP inputs only)
Note that in case the last connected valid input signal is disconnected, the
VP-774A will switch to the previous last-connected valid-input signal, and
then to the input before that and so on until the last disconnected inputs, and
then a “No Signal” screen will appear

Auto Switching Window (Main Tab)

Figure 50: The Routing & Scaling Page –
selecting the Inputs to Scan (PiP Tab)

When Scan mode is activated, the system scans the inputs from the highest to the
lowest priority in search of a valid input signal for each the Main and PiP windows.
The priority is ordered from the lowest input number (9) to the highest (1). For
example, if PC 1 and HDMI 2 have a valid signal and auto switching is enabled, the
VP-774A will scan through the inputs and select the HDMI 2 which is higher in the
priority list (see Figure 49

). Once the signal is no longer valid on HDMI 2, the

VP-774A will scan for the next highest-priority valid signal.

Note that you can Check/uncheck the box next to an input to include/exclude it from
the input scan list.

You can change the priority order as well by dragging an input button and dropping
it in a new location, as illustrated in the example in Figure 51

. In this example, CV is

moved up in the priority list to be scanned for a valid input after HDMI 1.
