1. Introduction
This is a high performance four input & two outputs switcher.
The output ports support Audio Return Channel (ARC) and HDMI Ethernet
Channel (HEC) according to HDMI v1.4 specification. The SWITCH-4X2 provides
a S/PDIF link from the sink to feed an AV receiver to get digital audio from the
sink decoder. The most typical application for this is a TV with built in Satellite
receiver that decodes digital audio and forwards the SPDIF signal through the
HDMI cable to the SWITCH-4X2 instead of running an additional SPDIF
connection wire.
Another HDMI 1.4 feature is the HEC that adds a connection to the HDMI
link that is capable of carrying the same data as a full duplex, 100Mbps
Ethernet connection. Connection a Fast speed HDMI cable with Ethernet allows
convenient integration of Digital Televisions (DTVs) into the end user’s home
network system. Simply connect the network cable to the SWITCH-4X2 and make
your TV part of the IP network through the HDMI cable.
