FAQ
HDMI connected, but no SDI output?
When two HDMI devices are connected together, the EDID communication
protocol automatically determines the highest resolution both devices
support and congures the HDMI link to that resolution. CHD 1412 supports
video formats up to 2160p60. If the HDMI Input is 2160p60, the SDI Output per
default will be 12G SDI.
If 3G, 1.5G or 270M SDI output is needed, the HDMI source device should
be manually set to output the desired video resolution.
The CHD 1412 has no internal scaler, but it is possible to force the desired
video format with LynxCentraal or yelloGUI. This is done by ignoring the formats
reported via EDID and selecting an appropriate format via LynxCentraal or
yelloGU. As a result the recognized HDMI resolution is changed and the output
might either be cropped or boxed. For examples, where HDMI formats result
in either cropping, boxing, or any combination of both, please refer to the
datasheet.
HDMI LED o, but connected?
The HDMI content may have HDCP copy protection, in which case the HDMI
present LED will be OFF and the module will block the conversion and provide
a black SDI output.
Note: Consumer devices usually include HDCP copy protection even if the source media is not copy
protected. Please verify the operation of the yellobrik module on a HDMI source which is known not to
have HDCP copy protection (e.g. most HDMI cameras) before contacting technical support.
Compatible Formats?
Any HDMI input can have a wide range of formats. These vary not only in
resolution, but also aspect ratio. We compiled a list of expected, compatible
formats. It can be found on the product page.
Note: We are continuously working on improving our products, this list might expand in the future.
