If an HDMI signal is HDCP protected, it can only appear on HDMI
outputs that are connected to HDCP compliant displays.

The VP-778 will not output a picture on an HDMI display that is not
HDCP compliant; instead it will show a green screen.

In the PiP 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 green.

The products described in this user manual are HDBaseT certified.

We strongly recommend that you use shielded twisted pair cable.

3.1 HDCP Compliance for HDMI inputs

3.2 About HDBaseT™ Technology

HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the ProAV – and also the home –
environment as a digital networking alternative, where it enables you to replace
numerous cables and connectors by a single LAN cable used to transmit, for
example, uncompressed full high-definition video, audio, IR, as well as various
control signals.

3.3 Using Twisted Pair Cable

Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products. For optimum range and performance use the
recommended Kramer cables available at www.kramerav.com/product/VP-778.

Define the output HDCP activation policy. Set to:
Follow Output (this option is recommended when the HDMI type
output is connected to a splitter/switcher) – to activate the HDCP
per output according to the setting of the HDMI acceptor to which it
is connected; that is, if the HDMI acceptor is not HDCP compliant,
the VP-778 always outputs without HDCP and vice versa.
Follow Input – to activate the HDCP on all HDMI type outputs in
the case that the video on the Main or PiP window is HDCP
encrypted.
Note that the VP-778 will output a green screen if the output
acceptor to which it is connected is not HDCP compliant, in the
case that the video on the Main or PiP window is HDCP encrypted.

6.3.1 Master Connection Settings

The Master Connection (HDMI OUT1, HDBT OUT1, HDMI OUT2 or HDBT OUT2)
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-778 is triggered to read the EDID
of the main display and change the output resolution value according to the native
resolution of the display.

If HDMI/HDBT is selected as the Master Connection, and a new display is
connected to the Master Connection output (hot plug), the VP-778 automatically
reads the EDID of that display and updates the output resolution accordingly.

If it is not supported by the selected Master Connection, the system searches for the
best supported resolution. If the search fails (for example, if the master connection is
disconnected or EDID is unreadable), the resolution will default to XGA.

FOLLOW INPUT – The aspect ratio and resolution of the input

video or graphics signal are both preserved (no scaling). For
example, a composite 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

FOLLOW OUTPUT – The aspect ratio and resolution of the

input signal is re-sized to precisely match the aspect ratio
and resolution of the VP-778 output signal. This may result in
some distortion to the input signal images

BEST FIT – This setting re-sizes the video or 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 either side.

LETTERBOX – This setting compresses the top and bottom

edges of the input signal, but fills the width of the screen. For
example, to preserve a widescreen film image on a 4:3
display.

Note that you can also customize the window size and position via the
“Y” commands (see Section 14.2) or protocol 3000 (see Section 14.4).

6.4.2 Selecting the Correct Aspect Ratio

6.5.1 The Luma Keying Feature

The luma keying feature lets you display the Channel 2 window (the key image) as
semi-transparent over the Channel 1 window. This feature can be used to have the
Channel 2 window display a static or dynamic logo, for example, which will appear
on a transparent background.

To apply the luma keying feature, first set the Channel 2 window to the desired size
and location and then turn luma keying On. The Channel 2 image will show without
its background.

The lower the luminance in the Channel 2 window, the more transparent it becomes,
thus letting the Channel 1 window image show. The higher the luminance, the less
transparent it becomes, not letting the Channel 1 window show through. To use this
feature it is recommended to set the Channel 2 image as follows: use low-luminance
colors for the background (the key image portion) and high-luminance colors for the
logo.

The VP-778 can function in two modes, the:

 Transition mode, see Section 7.1
 Overlay mode (for example, PiP), see Section 7.2

The operation modes are set by selecting the display Mode via the Layout menu
(see Section 6.3).

7.1 Transition Mode

In the transition mode you can setup the input, view it via the Channel 2 output and
then switch it to the Channel 1 output.

The VP-778 has two output channels (Channel 1 and Channel 2). Each channel
includes an HDMI connector and an HDBT port: Each of these channels functions
independently. An input is routed to the Channel 1 outputs by pressing that CH 1
INPUT front panel button. In the same way pressing a CH 2 INPUT front panel
button will route that input to the Channel 2 outputs.

Use the Channel 2 outputs to:

 See how the scaled output looks before displaying live during a presentation
 Harmonize the transition to the Channel 2 output after determining the look

and feel

 Use the OSD menu to make adjustments and choose the settings

When in the transition mode, you can set the speed of the transition; determine the
type of the transition (Swap or Follow) and the transition effect (Cut or Fade) via the
OSD menu (see, Section 6.3).

For example, select Cut for an instantaneous transition from the Channel 2 output
to Channel 1 and check Swap to interchange Channel 2 with Channel 1.

VP-778 - Port Tunneling

79

79

10 Port Tunneling

The port tunneling feature lets you send and receive simple RS-232 signals
between a controller and a serial device via the VP-778 which is connected to the
Ethernet and outputs via TP cable.

The example, illustrated in Figure 52, shows a Kramer room controller that is
connected to the VP-778 via the Ethernet. The HDBT OUT connector on the VP-778
is connected via TP to an HDBT receiver. This HDBT receiver connects to a display
via HDMI and RS-232.

Figure 52: Port Tunneling

The room controller sends RS-232 signals over the Ethernet via a dedicated
Tunneling port to the VP-778. The VP-778 sends these signals via TP to a display
that is connected to the receiver. This way, control data can flow between the room
controller and the display device, tunneling through the VP-778.

80

VP-778 - Port Tunneling

To setup and activate port tunneling on the VP-778:

1. Set the dedicated port tunneling Ethernet connection port type and port
number through which the VP-778 will be passing RS-232 signals via:

 OSD menu – in the Misc menu, select Advance>Port Tunneling>Port

Settings>Port Type, see Section 6.5.

 Y commands – select Misc>Advance>Port Tunneling>Port Settings To

change these settings see table in Section 14.2.2.

 PTN-CFG protocol 3000 command – see Section 14.7.4.1.

2. Set the HDBT UART via:

 OSD menu – in the Misc menu, select Advance>Port Tunneling>Port

Settings>Port Number, see Section 6.5.

 Y commands – select Misc>Advance>Port Tunneling>Port Settings To

change these settings see table in Section 14.2.2.

 UART protocol 3000 command – see Section 14.7.4.2.

3. Make sure that the VP-778 is connected to Ethernet.

The VP-778 is now ready to tunnel RS-232 signals via Ethernet port tunneling.

VP-778 - Routing Serial Data

81

81

11 Routing Serial Data

The VP-778 lets you route serial data through its various ports in the following
ways:

 Serial matrix – up to eight sets of connections are created for passing serial

data from a selected source to a selected destination.
Select the source/destination ports: port tunnelling, data, HDBT IN1, HDBT
IN2 HDBT OUT1, HDBT OUT2 or none (for no connection)

 USR buttons – a programmed command is launched to a selected

destination with a press of a USR button (see Section 8.1.4).
Select the source/destination ports: port tunnelling, data, HDBT IN1, HDBT
IN2 HDBT OUT1, HDBT OUT2, all or none (for no connection)

VP-778 - VP-778 RS-232 Communication Protocol

All three tables together include all the protocol commands, but they are
not identical and do not always include the same information. Some of
the data may appear in one or two of the tables but not in the third table
and vice versa.

14 VP-778 RS-232 Communication Protocol

The Kramer Protocol lets you control the VP-778 from any standard terminal
software (for example, the Windows® HyperTerminal Application).

14.1 Using the Communication Protocol

There are three different methods to control the VP-778 RS-232 or the Ethernet:

 Protocol commands mimicking the OSD, see Section 14.2
 The button functions mimicking the remote controller buttons (as well as the

front panel buttons), see Section 14.3

 Protocol 3000 common commands, see Section 14.4

The protocol 3000 communications protocol uses a data rate of 115200 baud, with
no parity, 8 data bits, and 1 stop bit.

14.2 Communication Protocol: Mimicking OSD

The audio/video protocol commands defines all the function numbers, their valid
parameters can be used with protocol 3000.

14.2.1 Using the Communication Protocol with Protocol 3000 (the “Y” Command)

Set Command:

Type in: “Y Control_Type=0,Function,Param”
Reply: “~id=01Y Control_Type=0,Function,Param OK”

Set command example: set HDCP mode for input 1 (113) to “On”

Send: “#y 0,113,1”

Result: “~01@Y 0,113,1 OK”

Line Feed, ASCII code 0x0A

Get Command:

Type in: “Y Control_Type=1,Function”
Result: “~id=01Y Control_Type=1,Function,Param”

Get command example: get HDCP mode for input 3 (113):

Send: “#y 1,113”
Result: “~01@y 1,113,1”

The “Y” command also supports the value increment/decrement of any command

using the ‘+’ or ‘-‘ signs as the third parameter of the “Y” command.

For example, in order to decrease the volume on the DVI-U2 input (165)

Send: “#Y 0,165,-<CR>”
Reply: “~01@Y 0,165,-OK”

Note that if the value after the decrease is out of range, the reply will show an error
such as:”~01@Y ERR -03”

14.2.2 Protocol Table: Mimicking OSD

You can associate a function number to its description and valid parameters
intuitively by navigating the OSD menu according to the following logic:
A function number is directly related to its location in the OSD menu.
For example, the second menu on the OSD is Layout (2 in the hundreds). The third
menu item in Layout is Overlay Settings (2 in the tens), therefore the function
number for it will be 230 (2nd item on the Main menu and the 3rd item in the Layout
submenu (see also Section 6.1). When navigating in the OSD MENU you will be
able to see the Overlay Settings valid parameters.

92

VP-778 - VP-778 RS-232 Communication Protocol

Note that for the Inputs, menu levels 3, 4 and 5 are valid for each input
from 1 to 8. For example, Type (3rd level) item is 111 for Input 1 and 121
for Input 2, and so on. In order not to repeat the Inputs menu for each
input, the function list will have an x denoting the input number from 1 to 8.
For example, the Type item will have 1x1 as the function number x being
from 1 to 8.

The following table shows the Program function numbering.

Note that some items that appear in red on the OSD menu seem missing
in the table below. These items will be enabled in future firmware and will
be described in detail.
