Getting Started

2.1 Quick Start

This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview

The VS-44H is a high-performance matrix switcher for HDMI signals. It

reclocks and equalizes the signal and can route any input to any or all

outputs simultaneously.

More specifically the VS-44H features:

•Up to 1.65Gbps bandwidth per graphic channel1

•Four input selector buttons to switch to the four selectable outputs

•Support for HDCP (High Bandwidth Digital Content Protection)

•I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent

EDID handling and processing algorithm that ensures Plug and Play

operation for HDMI systems

•An OFF button to disconnect an output

•A PANEL LOCK button to prevent unwanted tampering with the

buttons on the front panel

•1U-high, 19” size for mounting in a professional rack enclosure

The VS-44H can be controlled using the front panel buttons, or remotely via:

•RS-232 serial commands transmitted by a touch-screen system, PC, or

other serial controller

•The Kramer infrared remote control transmitter

•The ETHERNET

3.1 Defining the EDID

The EDID (Extended Display Identification Data2

) is a data-structure,

provided by a display, to describe its capabilities to an HDMI source. The

EDID enables the VS-44H to “know” what kind of monitor is connected to

the output. The EDID includes the name of the manufacturer, the product

type, the timing data supported by the display, the display size, luminance

data and (for digital displays only) the pixel mapping data.

1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions

2 Defined by a standard published by the Video Electronics Standards Association (VESA)

Overview

3.2 About HDMI

High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital1

In particular, HDMI:

audio/video interface, widely supported in the entertainment and home cinema

industry. It delivers the highest high-definition image and sound quality. Note

that Kramer Electronics Limited is an HDMI Adopter and an HDCP Licensee.

•Provides a simple2interface 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

lengthy3

•Supports standard, enhanced, high-definition video, and multi-

channel digital audio

cable

•Transmits all ATSC HDTV standards and supports 8-channel digital

audio, with bandwidth to spare to accommodate future enhancements

and requirements

on a single cable

•Benefits consumers by providing superior, uncompressed digital

video quality via a single cable5

•Is backward-compatible with DVI (Digital Visual Interface)

, and user-friendly connector

•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

HDMI has the capacity to support existing high-definition video formats

(720p, 1080i, and 1080p/60), as well as standard definition formats such as

NTSC or PAL.

1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-

to-analog conversions

2 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

3 HDMI technology has been designed to use standard copper cable construction at up to 15m

4 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

5 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a

simple, cost-effective manner

3.3 About HDCP

The High-Bandwidth Digital Content Protection (HDCP) standard

(developed by Intel), protects digital video and audio signals transmitted

over DVI or DVI 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.

3.4 Recommendations for Best Performance

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer VS-44H

away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated noise

levels (often associated with low quality cables).
