Introduction
About the KD-VP2500
The KD-VP2500 is a digital video processor, audio transcoder, video/audio switcher and universal
“distribution center”. It is capable of scaling and de-interlacing virtually any input resolution and
outputting to virtually any standard or high definition display up to 1080p. The unit serves as an
excellent solution for inter facing standard or high definition video sources and computers with
displays.
The KD-VP2500 uses motion-adaptive deinterlacing, 3:2 pull down engines and 3-D noise
reduction. The unit also features time base correction (TBC) and accepts analog and digital video
signals up to 1080i.
The design intention of limiting input resolution only up to 1080i ser ves a practical purpose
considering that the KD-VP2500 is a video scaler. To understand why, consider two scenarios of
creating HD-DVD and Blu-Ray content.
Scenario One:
Original material is recorded at 1080P/24hz to the DVD. This signal is read from the disc then
converted loss free to 1080i/60hz. From here, HD-DVD and Blu-Ray players upscale this
1080i/60Hz signal to 1080P/60hz using low cost scaler chips. Therefore, the 1080P output on
consumer players started out as a 1080i signal and then ran through an inferior scaling chip to
achieve 1080P.
Scenario Two:
Original material is recorded at 1080i/60hz to the DVD. From here, HD-DVD and Blu-Ray
players upscale this 1080i/60Hz signal to 1080P/60hz using low cost scaler chips. Again, the
1080P output on consumer players started out as a 1080i signal and then ran through an
inferior scaling chip to achieve 1080P.
The component outputs on HD-DVD and Blu-Ray players always output the 1080i/60hz signal
before scaling, making these analog outputs more ‘true’ to the original content. The HDMI outputs
are the only signals that are affected by these low cost scaling circuits.
When HD-DVD and Blu-Ray devices are connected to the KD-VP2500 via HDMI, the Key Digital
unit forces the players to output 1080i, the signal closest to the original format. We then get access
to the cleanest possible signal and transfer the responsibility of scaling to 1080P to the high quality
scaling engine in the KD-VP2500.
Any audio input-to-output routing combination is possible on the KD-VP2500. The audio
processing capabilities of the unit allow analog to digital (Coaxial, Toslink and HDMI PCM), digital to
digital (format conversion) and digital to analog conversion.

Setup and Operation
After all cabling is connected and the unit powered on, there are some functional settings
which need to be made. These include output resolution, screen and audio/video association
menu assignments as well as proper color space settings. Additionally, there are many detailed
parameters which can be adjusted to taste or to compensate for different sources and/or displays.
These parameters are grouped within the picture and screen menus.
The following detailed steps will facilitate easy setup and operation of the KD-VP2500.
Setup
Configure the functional settings of the KD-VP2500. It will help to have a video signal present at
selected input
1. Set desired output resolution – Navigate to the ‘Output Resolution’ menu. Press the left or
right arrow button repeatedly until the desired resolution is displayed. These resolutions take
effect immediately and there is no need to press the ‘select’ button to engage the setting.
2. Set the A/V associations - Each video input is able to be associated with any audio input.
Navigate to the ‘A/V Association’ menu until the desired video input is displayed. For example,
to assign stereo analog input 1 to Component 1, go to ‘A/V Set Component 1’. Press the left or
right arrow button until Stereo 1 is displayed. Assignment takes place immediately.
3. Set the intended color space conversion (CSC) for HDMI Input/Output – Proper color
space must be set for HDMI input and output. The correct setting depends on the source
and display characteristics. Navigate to the ‘HDMI In CSC’ or ‘HDMI Out CSC’ menu. There
is an ‘auto’ setting in these two menus which can be used most reliably. Alternatively, it may
sometimes be necessary to select either RGB or YCbCr color space conversion. With any of
the above menus, the correct setting will be apparent when viewing the display, as the wrong
setting will yield incorrect colors in the image. In order to determine, with accuracy, what the
correct settings should be, use the built-in color bar test patterns on the KD-VP2500 to assure
proper setup.
4. Set the intended CSC for the analog video output – Proper color space must also be set
for the analog video output. Navigate to the ‘Analog Out CSC’ menu and select either YPbPr
or RGB, depending on the requirement of the display. With the above menu, the correct setting
will be apparent when viewing the display, as the wrong setting will yield incorrect colors in the
image. In order to determine, with accuracy, what the correct settings should be, use the builtin color bar test patterns on the KD-VP2500 to assure proper setup.
5. Setup the HDMI output port – Navigate to the ‘HDMI Out Setup’ menu. Use the left or
right arrow button to select either DVI or HDMI. When using DVI equipped displays and an
appropriate HDMI to DVI adapter cable out of the KD-VP2500, set this menu to DVI. When
using HDMI equipped screens, set this menu to HDMI.
After the above functional settings have been configured, detailed adjustments can be made for
each individual video input source. To begin the input source setup, choose an input with which
to start. Complete the steps below, and then continue on to the next video input, completing the
same steps for each source. The KD-VP2500 will automatically store every parameter below for
each input.

Operation
After all of the setup steps above, the KD-VP2500 is ready for operation. Most applications will
involve only input switching for day to day operation. There are a several options for controlling the
unit. Most commands can be issued via IR remote control, RS-232 or simply by using the front
panel buttons.
Front Panel Control
For switching inputs, simply press the ‘Input Select’ button on the right side of the front panel. See
number 8 on Figure 4. Pressing this button repeatedly will cycle through all video inputs.
IR (Remote Control)
The KD-VP2500 ships with an IR remote control providing direct selection of inputs and adjustment
of the most common parameters via ‘hot buttons’. Hot buttons enable quick adjustment to these
parameters without the need to access the extensive menu through the LCD. As illu strated in the
following diagram, these convenient keys are clearly marked and aid in configuring and operating
the KD-VP2500.

Examples of RS-232 Commands
1. Input Switching
» IVx x = desired input
Example: To switch to component video input 3, issue the command IV3
2. Picture Contrast Adjustment
» CTU/CTD/CTI# # = setting between -50 ~ 50
Example: To increase the contrast, issue the command CTU
Example: To decrease the contrast, issue the command CTD
Example: To set the contrast to a value of 15, issue the command CTI15
3. Picture Aspect Adjustment
» AP# # = aspect setting 1 ~ 6

*The PAL 2:2 pull down process is used specifically for conversion when viewing content filmed at 24 frames/second on
50hz displays. The KD-VP2500 default setting is ‘On’, which means it automatically detects the need for this conversion
process. If the source signal i s noisy, then this process can sometimes yield jagged edges and, therefore, we offer the
option to turn off ‘auto detect’.
5. Screen Horizontal Picture Adjustment
» HPU / HPD / HPI# # = setting between -20 ~ 20
Example: To shift the picture left, issue the command HPU
Example: To shift the picture right, issue the command HPD
Example: To set the horizontal position to a value of 5, issue the command HPI5
6. Audio/Video Association Set
» AVx # x = desired video input # = desired audio input
Example: To associate PCM input 2 with component input 3, issue the command AV5 6
Please not that there is a space nece ssary between ‘x’ and ‘#’
7. Output Resolution Set
» OR# # = output resolution 1 ~ B
Example: To set the output resolution to 1920X1080i, issue the command OR2
8. HDMI Input Color Space Conversion
» IC# # = setting between 1 ~ 3
Example: To set the HDMI input CSC to YCbCr, issue the command IC1

Firmware Update
From time to time, Key Digital may provide firmware updates for the KD-VP2500. These updates
are optional, and should only be performed as instructed by Key Digital. Below is the procedure for
updating the firmware. Please note that incorrect update processes can result in an unusable unit.
Follow the detailed directions carefully.
Firmware Update Procedure
1. Check our web site at www.keydigital.com for the latest firmware update ZIP file. Download
and unzip the firmware ZIP file to any directory on the PC. All of the unzipped files that are
created must be located in same directory on the PC.
2. Be sure power is disconnected to the KD-VP2500 unit. The power supply must be
disconnected (either from the back of the unit or from the wall outlet) to have a
complete power shutdown - reset.
3. With power disconnected, set the rear-panel slide switch (see page 5 number 12) to program
mode “Mode A”. Do not yet apply power to the unit.
4. Connect an RS-232 cable to the COM1 serial port on the PC, and the other end to the RS-232
port on the rear panel of the KD-VP2500 unit. Make sure that no other devices are using the
COM1 serial port on the PC. Use of laptop computers has proven less reliable than desktop
systems. Please refrain from updating the firmware with laptops.
5. Apply power to the KD-VP2500 unit.
The power supply must be reconnected to the unit.
6. Double-click the ‘isynchd.bat’ file from within the ZIP folder. The command mode window
should pop up. Monitor this pop-up window to verify the update progress.
7. If an error occurs, check the RS-232 connection and repeat all of the above steps.
8. When the update is complete, disconnect the RS-232 cable between the unit and the PC.
9. Disconnect power from the KD-VP2500 unit. The power supply must be disconnected
(either from the back of the unit or from the wall outlet) to have a complete power
shutdown - reset.
10. With the power disconnected, set the rear-panel slide switch to “Normal” mode.
11. Turn on power to the KD-VP2500 unit. Power supply must be reconnected to the unit
first; then push the ‘On” button on the front panel.
12. The firmware update is now complete, and the KD-VP2500 is ready for operation. Upon boot-
up, the LCD will display the new firmware version
