INTRODUCTION 

The 

CV-57KG 

HDMI extender over single cat.X

 boosts up your video/audio transmission distance 

up  to  60m  (200ft)  in  HDTV  1080i  format,  40m  (130ft)  in  HDTV  1080p  format,  and  20m  (65ft)  in  HDTV 
1080p with 36-bit color depth. CV-57KG also supports the most advanced 3D video format complaint with 
HDMI specification 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/DVI enabled TV sets or LCD PC monitors. 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. 

The  CV-57KG  includes  two  units:  transmitting  unit  CV-57KG-TX  and  receiving  unit  CV-57KG-RX. 

The  transmitting  unit  is  used  to  capture  the  input  HDMI/DVI  signals  and carry  the  signals  via  one  cost 
effective Cat.5/5e/6 cable. The receiving unit  is responsible for equalizing the transmitted HDMI signal. 
The transmission distance between the sending and receiving units can be up to 60m (200ft) 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.

The claimed transmission distance here is subject to the grade of installed cable(s), source device and 
display.  

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!
