SDI Output Tab
Screen
The SDI Output tab shows the current settings for both of the SDI outputs. Because
the outputs can be configured independently, one output may be the Primary format
and the other output may be the Secondary format. If an input/output has no video,
it will be indicated on the block diagram ("No Video").
SDI Output Tab Screen Settings—SDI Output 1 and 2
Configure SDI 1 and 2 via pulldowns:
AJA Control Panel, SDI Output Tab
Select Options:
Primary—when selected, this indicates that the SDI output is set to the same format
as the framebuffer. That value will be listed in blue.
Secondary—when selected, this indicates that the SDI output is set to a format
different from the framebuffer (Primary Format). That secondary format value
will be listed in green. This shows that active processing of the video is taking
place (format change and possibly even up/down-conversion).
Video+Key—when selected, this indicates that the SDI 3 video is set to the same
format as the framebuffer. SDI 4 is set to a video key signal associated with SDI 3
(the shape to be cut out from the video - this will appear as a black and white
image/matte). Using the second Io XT output as an Alpha Channel key, with the
video output, may be useful for feeding production switchers, DVEs or other
professional video equipment. If Video+Key has been selected as an output, the
block diagram will indicate the SDI outputs with video in blue and the key in red.
Stereo—when selected, this indicates that SDI 1 represents the left eye output and
SDI 2 represents the right eye output of stereoscopic material.Io XT also offers
single link 3Gb output of multiplexed Stereo 3D.
