• Use Kramer high performance high resolution cables
• Use only the power cord that is supplied with this machine
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
• Do not secure the cables in tight bundles or roll the slack into tight coils
• Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
• Position your Kramer VP-437N away from moisture, excessive sunlight and
dust

VP-437N – Overview 3
3 Overview
The Kramer VP-437N is a high quality presentation switcher and scaler. It accepts one
of seven inputs: a component video on RCA connectors, computer graphics on a
15-pin HD connector, composite video on an RCA connector, s-Video on a 4-pin
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, an RGBHV
video output together with a digital audio output and an analog 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-437N is HDTV compatible and the resolution can be up- or down-scaled as
follows: Native, VGA, SVGA, XGA, SXGA, UXGA, 480i, 480p, 576i, 576p, 720p
(@50 and 60Hz), 1080i (@50 and 60Hz), 1080p (@50 and 60Hz), WXGA, WSXGA,
WUXGA, 1280x800, 1440x900, 1400x1050 and 1600x900.

3.1 About HDMI—General Description
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital audio/video
interface, widely supported in the entertainment and home cinema industry. HDMI
ensures an all-digital rendering of video without the losses associated with analog
interfaces and their unnecessary digital-to-analog conversions. It delivers the
maximum high-definition image and sound quality in use today. Note that Kramer
Electronics Limited is an HDMI Adopter and an HDCP Licensee.
HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered
trademarks of HDMI licensing LLC.
In particular, HDMI:
• Provides a simple 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 cable
SIMPLICITY - 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
LENGTHY CABLE - HDMI technology has been designed to use standard copper cable
construction at up to 15m
• Supports standard, enhanced, high-definition video, and multi-channel digital
audio on a single cable
MULTI-CHANNEL DIGITAL AUDIO - 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
• Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
VP-437N – Overview 5
• Benefits consumers by providing superior, uncompressed digital video quality
via a single cable, and user-friendly connector
HDMI provides the quality and functionality of a digital interface while also supporting
uncompressed video formats in a simple, cost-effective manner
• 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), standard definition formats such as NTSC or PAL, as well
as 480p and 576p
3.2 10BAbout HDCP—General Description
The High-Bandwidth Digital Content Protection (HDCP) standard, developed by
Intel, protects digital video and audio signals transmitted over DVI or HDMI
connections between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios) from
having their programs copied and shared, the HDCP standard provides for the
secure and encrypted transmission of digital signals.
