Aja HDMI To SDI With Region Of Interest Scaling
AJA's OG-ROI-HDMI is an openGear card that allows exceptionally high-quality conversion of computer and HDMI outputs to 3G-SDI baseband video. With incredible region-of-interest image scaling as well as aspect ratio and frame rate conversion, OG-ROI-HDMI fulfills the growing need to properly incorporate extractions from HDMI sources and computer signals into the video world without sacrificing budget or space.
Connectivity
OG-ROI-HDMI utilizes a direct loop through, allowing it to be placed in-line so you still have a connection to an external monitor while extracting to SDI. The reference input ensures the SDI signal out of OG-ROI-HDMI is locked for use throughout a production or facility.
Audio
OG-ROI-HDMI accepts 2-channel analog audio from the 2x 3-pin terminal blocks connectors or embedded 8-channel audio from an HDMI input. The audio source and routing can be selected in the DashBoard software and is embedded into the SDI output. This allows computer audio to be embedded within the SDI signal for easy, synchronized routing.
openGear Compatibility
The openGear standard ensures that AJA cards will be compatible with other openGear products from certified openGear partners. With a growing list of products, openGear is the future of rack frame products.
Flexible I/O
The modular rear panel allows custom I/O connections per card (included with individual cards).
Failsafe
The optional redundant power supply provides a secondary power source in the event of a primary power failure.
Ethernet Access
A standard Ethernet connection allows the frame to be accessed via the Dashboard application for overall frame communication. Optional per-card Ethernet access can be installed in the frame for advanced communication with compatible openGear cards.
