3 Overview
The KW-11T and KW-11R is a high-definition, wireless, HDMI transmitter and
receiver combination for indoor use over short range distances.
The KW-11T converts an HDMI signal into a wireless signal. The KW-11R
converts the wireless signal back into HDMI.
The KW-11T and KW-11R support:
•Uncompressed video resolutions up to 1080p @60Hz
•Zero latency
•EDID
•HDCP
•CEC
•OSD (On Screen Display)
•A transmission range of up to 12m (39ft)
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

4 KW-11T/KW-11R - Overview
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
•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 CEC, 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
3.2 About 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.
