4.3 EDID Management
An essential part of operation is the EDID table, which is transmitted to the source from
the HDBaseT Transmitter input.
The VL120025 features advanced built-in EDID management function, and it should
follow the below rules:
When the
“
HDMI-1 OUT
”, “
HDMI-2 OUT
” and “
HDBT OUT
” ports are connected
with devices, the input source device will firstly read the EDID from the HDBT
output device (such as HDTV) which is connected to the HDMI output port of
HDBaseT Receiver. If disconnecting
the HDBT output device, the EDID data don’t
need to be read again. If changing the HDBT output device, the EDID data will be
read again from the new device.
When the
“
HDMI-1 OUT
”, “
HDMI-2 OUT
” ports are connected with devices, but the
“
HDBT OUT
” port aren’t connected with any device, the input source device will
firstly read the EDID from the HDMI-1 output device of the last repeater (such as
HDTV). If disconnecting the HDMI-1
output device, the EDID data don’t need to be
read again.
Note:
The input source will re-read the EDID date according the above rules when the
system is powered down and reset.
4.4 HDCP Management
The VL120025 offers advanced HDCP management to allow greater compatibility with
other devices. The output will always be encrypted or unencrypted, following the status
of the source content. If the content is encrypted, the output of the HDBaseT receiver
will be encrypted; if the content is unencrypted, the output of the HDBaseT receiver will
be unencrypted.
The VL120025 HDCP2.2 compliant and backward compatible to the down-level version.
