3 Overview
The Kramer VP-437 is a high quality presentation switcher and scaler. It
accepts one of seven inputs: a component video
1
on RCA connectors, computer
graphics on an HD15F connector, composite video on an RCA connector, s-
Video on a 4p connector and two HDMI signals. It scales the video, embeds the
audio, and outputs the signal to the HDMI output as well as to a computer
graphics output and an RGBHV video output together with a digital audio
output.
The VP-437 Presentation Switcher / Scaler:
Is HDTV compatible and the resolution can be up- or down-scaled
2
Has analog audio inputs and a digital (S/PDIF) audio output
Automatically detects and selects the audio source for the HDMI input.
Default selection is HDMI – if this is not present, then the machine uses
the audio from the analog input
Comes with an On-Screen Display (OSD) for easy setup and adjustment,
accessible via the IR remote control and via the front-panel buttons
Has a non-volatile memory that retains the last settings used
Supports firmware upgrade

Control your VP-437:
Directly, via the front panel push buttons
By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
Remotely, from the infra-red remote control transmitter
Via the Ethernet
The VP-437 is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included, and is fed from a 100-240 VAC universal switching power supply.
1 Also known as Y, Pb, Pr, Y, Cb, Cr and YUV
2 The resolutions which can be selected include: 1080i, 1080p, 576i, 576p, 720p, 1080i, 1080p, WXGA, WSXGA, WUXGA,

3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the maximum high-definition image and sound quality in use
today. Note that Kramer Electronics Limited is an HDMI Adopter
2
and an HDCP
Licensee
3
.
In particular, HDMI
4
:
Provides a simple
5
interface between any audio/video source, such as a
set-top box, DVD player, or A/V receiver and video monitor, such as a
digital flat LCD / plasma television (DTV), over a single lengthy
6
cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
7
on a single cable
Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
Benefits consumers by providing superior, uncompressed digital video
quality via a single cable
8
, and user-friendly connector
Is backward-compatible with DVI (Digital Visual Interface)
Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
Has the capacity to support existing high-definition video formats (720p,
1080i, and 1080p/60), standard definition formats such as NTSC or PAL,
as well as 480p and 576p.
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions

5 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
6 HDMI technology has been designed to use standard copper cable construction at up to 15m
7 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
8 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

deterioration in signal quality due to poor matching, and elevated noise-
levels (often associated with low quality cables)
