With an increasing number of HDMI enabled entertainment devices becoming 
available, such as games consoles, DVD players and network streaming boxes, you 
are likely to find yourself lacking in HDMI ports with a large number of sets 
only possessing the one.
The Simplecom CM340 HDMI Switch Box solves this problem by allowing 4 HDMI 
sources to be connected to a single HDMI port on a HDTV. Switching between the 4 
devices is then made easy by the front control buttons so you no long have to 
spend ages, fiddling with wires behind your TV.
HDCP Compatible, thanks to mechanical switch design without re-processing of 
the HDMI signal, the TV will get the original signal directly from HDMI sources 
by switching physical pins of HDMI port, which will overcome interference and 
incompatibility issue caused by processor chip based HDMI switch, especially for 
HDCP protected contents such as Foxtel, Apple TV.
