1.0 INTRODUCTION
It is a Home Entertainment System with very powerful functions. It supports 4
HDMI inputs and 1 HDMI output. With Built-in HDCP engine for Instant Port
Switching (IPS), 4 Ports switching can be very fast because there is no need to
redo HDCP authentication when port switching occurs. With the built-in HEC
(HDMI Ethernet) and ARC (Audio Return Channel) chips, it can split HEC
which is from HDTV to Ethernet signals and can split ARC which is also from
HDTV to Coaxial, Toslink, Stereo audio signals that are also from source
device through ARC ON/OFF button on the Remote Control.
