INTRODUCTION
1. The claimed transmission distance here is subject to the grade of installed cable(s), source
device and display.
2. For over CAT5/COAX transmission, the cable(s) has to be solid, not stranded. Any keystone jack
along the transmission path will kill the transmission performance significantly!

transmission distance up to 50m (165ft) in HDTV 1080i format, 40m (130ft) in HDTV 1080p format, and

format and therefore guarantees the highest 3D video compatibility on the market. With only one cost
effective Cat.5/5e/6 cable, users can readily extend HDTV sources from DVD players, Blu-ray Disc player,
PS3, PC, and any other kinds of sources compliant with TMDS to distant display monitors including HDMI
or DVI enabled TV sets or LCD PC monitors. With the advanced design for the latest HDMI technology,
deep color video, DTS-HD Master Audio or Dolby TrueHD audio, and HDCP supports and compatibility
are all further insured. This flexibility makes HDCP compliant DVD players or PS3 transmit utmost high
quality video and audio with a greater distance at the minimal cost, when integrating several components
apart. In addition,
allows users to boost IR control distance up to 100m (330 ft) and makes IR control possible through only
single Cat.5/5e/6 cable including HDMI signals.

The
transmitting unit is used to capture the input HDMI / DVI signals with IR control packets and carry the
signals via one cost effective Cat.5/5e/6 cable. The receiving unit is responsible for equalizing the
transmitted HDMI signal and reconstructing IR signals. The transmission distance between the sending
and receiving units can be up to 50m (165ft) at HD 720p or 1080i; or 40m (130ft) at Full HD 1080p. With
an 8-level equalization rotary control on the receiving unit, users can adjust the equalization strength to
the received HDMI signals accordingly, and therefore optimize the transmission distance between source
and destination.
