CONCERNING THE VD-1673

1.1 General description

The model VD-1673 is an HDMI signal switcher which is provided with two HDMI input ports and

eight output ports. It enables the input ports to be switched for TVs which have a multiple number of

HDMI inputs without having to change the cable connections. When it is used together with a

generator in the VG series, it enables the signals of the input ports to be monitored easily.

The switcher makes it possible to distribute the TMDS signals among the HDMI input signals, and

output them when HDCP is not going to be executed.
