CHAPTER 4
SDI Live Video Input and Control

Displaying Live Video

When Media Folder 255 is selected, the video capture DMX assignments are as follows.
DMX = 1 Standard definition SDI source 1
DMX = 2 Standard definition SDI source 2
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. 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
DLHD fixtures to have the same SDI feed without a switcher/splitter device.
• 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.
