OG-ROI Series openGear card v1.6 29 www.aja.com
In default mode, the OG-ROI passes up to eight channels of embedded audio
from the HDMI or DVI input to the SDI output.
NOTE: The OG-ROI-DVI model can receive both DVI and HDMI protocol input, and
accepts audio if it is embedded in an HDMI signal. However, the DVI protocol
does not carry audio, so if the ROI-DVI is receiving DVI input, only analog audio
can be embedded to the output.
Input Select
Use this control to select which input audio to pass to the SDI output.
• HDMI - This selection passes the HDMI incoming audio to the SDI output (up
to 8 channels).
• Analog- This selection passes only the Analog audio input for inclusion into
the SDI audio stream. In this case, you can use the
Analog Out Map
pulldown
menu to select the specific channel pair you want to carry the signal.
• HDMI - This selection causes the Analog audio input to replace
one pair of the HDMI audio channels on the SDI output. The analog audio is
inserted on the channels defined by the Analog Out Map pulldown.
• None - No audio is output (mute) on the SDI output.
HDMI Conversion
The
Convert Rate
button enables OG-ROI Series to convert incoming HDMI audio
between 32 kHz to 96 kHz to 48 kHz (the SDI native audio standard). If you don’t
want to convert, choose Pass Through.
Analog Out Map
This control selects which two SDI embedded audio channels receive the
incoming L R analog audio when Input Select is set to Analog or HDMI.
Choose from Ch 1-2, Ch 3-4, Ch 5-6, or Ch 7-8.
