Overview
3 Overview
Each high quality HDMI Distributor accepts one of two HDMI inputs, and
distributes the selected signal to:
@ 8 outputs (the VM-28HDMI)
@ 12 outputs (the VM-212HDMI)
@ 16 outputs (the VM-216HDMI)
Each machine—the VM-28HDMI, VM-212HDMI, and VM-216HDMI—has:
@ Support for up to 1.65Gbps bandwidth per graphic channel1
@ The ability to read and store, in non-volatile memory2, the EDID3 block at
each input4 from an output display device, so it can then provide the EDID
information to the HDMI source even if the display device is not connected
@ A default EDID for fast and efficient connection of the unit5
@ Three modes of operation: the Distribution mode6, the EDID mode7, and
the EDID Reset mode7
@ A 19" 1U rack-mountable enclosure, and is fed from a 100-264 VAC
universal switching power supply
3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital8
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 Adopter9 and an
HDCP Licensee10.
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 While the machine is ON
3 EDID is Extended Display Identification Data (see section 3.2 for a detailed definition)
4 Independently. Each input can be set with its own EDID block
5 Lets you use the EDID default value when no display from which to read the EDID is connected
6 Used to distribute an input signal to several outputs
7 See section 5.2
8 Ensuring an all-digital rendering of video wit hout the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions

KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
In particular, HDMI:
@ Provides a simple1 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 lengthy2 cable
@ Supports standard, enhanced, high-definition video, and multi-channel
digital audio3 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 cable4, 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
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
3.2 Defining EDID
The Extended Display Identification Data (EDID5) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the VM-28HDMI / VM-212HDMI / VM-216HDMI to
“know” what kind of monitor is connected to the output. The EDID includes
the manufacturer’s name, 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 With video and mu lti-channel au dio comb ined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
2 HDMI technology has been designed to use standard copper cable construction at up to 15m
3 HDMI supports mu ltiple 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
4 HDMI provides the quality and functionality of a di gital interface while also supporting uncompressed video formats in a
simple, cost-effective manner
5 Defined by a standard published by the Video Electronics Standards Association (VESA)
