The CV-57G HDMI 1.3 over Single CAT5 Extender 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. With only one cost effective LAN 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. With the state-of-the-art Silicon Image chipsets
equipped, deep color video, DTS-HD 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.
The CV-57G includes two units: transmitting (CV-57G-TX) and receiving (CV-57G-RX) units. The transmitting
unit is used to capture the input HDMI/DVI signals and carry the signals through one RJ-45 connector into one
cost effective CAT-5/5e/6 LAN cable. The receiving unit is responsible for equalizing the sent TMDS multimedia
data. The transmission distance between the sending and receiving units can be up to 60m (200ft) under HD
(720p/1080i) or 40m (130ft) under Full HD (1080p). With an 8-level equalization control knob on the receiving
unit, users can adjust the equalization strength to the received TMDS signals accordingly, and therefore optimize
the transmission distance between source and destination.

The length depends on the characteristics and quality of the cables. Higher resolutions and longer
transmission distances require low skew cables (<25ns/100m) for best performance. Unshielded CAT6
with metal RJ-45 connectors is recommended.
