Displaying Live Video

When Media Folder 255 is selected, the video capture DMX assignments are as follows.
DMX = 1 SVideo source 1
DMX = 2 Standard definition SDI source 1
DMX = 3 SVideo source 2
DMX = 4 Standard definition SDI source 2
DMX = 5 High definition SDI source 1
DMX = 6 High definition SDI source 2
DMX = 7 High definition SDI source 3
DMX = 8 High definition SDI source 4
For a DL fixture with a standard definition SDI card installed, svideo capture will be at DMX = 1
and SDI video capture will be at DMX = 2. For a DL fixture with an high definition SDI card
installed, svideo capture will be at DMX = 1 and SDI video capture will be at DMX = 5.
A DL.3 fixture can both capture SDI (accept external SDI feeds) and also output its camera
through SDI. There are two separate ports on the DL.3 back panel.
NOTE: A DL.3 fixture cannot capture SDI and output its own camera feed
through SDI simultaneously. So, unlike the S-video capture, it cannot
be displaying the SDI feed of another fixture while outputting its own
camera through SDI.
To switch between SDI in and SDI out, access the Motion Control parameters through your DMX
console. The iris does not have to be closed for the switch to happen. See Chapter 14: Fixture
Motion Functions and Appendix A: DMX Protocol for more detailed information.
Note the following when using the SDI video input and output option:
• While capturing SDI, anything that is being fed to the "In" SDI port will be mirrored on the
"Out" port. Therefore, it is possible to daisy chain fixtures together via SDI, allowing multiple
DL.3s to have the same SDI feed without a switcher/splitter device.
• In order for the DL.3 to output its camera through SDI, the S-video relays must be set to
internal camera capture (otherwise known as camera feedback). This is necessary because
the S-video signal must be routed to the computer.
• The "frame delay" on the SDI capture is nearly identical to that of the S-video capture. The
difference cannot be seen with the naked eye.
• It is possible for a unit to have both SDI and S-video inputs coming in at the same time.
