B.1.2 Selecting SDI Inputs
Depending on the video standard of the SDI video you want to analyse/convert, you need to set
the Connections window to detail the 1, 2 or 4 SDI Input ports that you will be using for the cables
over which the video input is delivered.
IMPORTANT: For correct results to be achieved, the ordering of the inputs in the list you create
needs to correspond to the cable/link numbering detailed in the appropriate SMPTE standard. For
instance, where 4K video is delivered over four separate cables, the image is divided into four
‘Subimages’ and you need to arrange that the first port in the list is used for the cable carrying
Subimage 1, the second Subimage 2, the third Subimage 3 and the fourth Subimage 4.
Looping Back Output
To make it easy to analyse the output from the Generator, the list of SDI Inputs offered by
the
Ultra
includes the output on SDI 1 to SDI 4, AUX 3 and AUX 4. So if the Generator
is outputting a set of four subimages to ports SDI 3, SDI 4, AUX 3 and AUX 4, then instead
of having to plug cables between these ports and the remaining four SDI ports, the
Analyser/Converter of the Ultra can be configured to work on these subimages by selecting
SDI 3 Output , SDI 4 Output , AUX 3 Output and AUX 4 Output as the four inputs.
Using these Output options also has the advantage that the selected output ports can continue to
be used to output the generated signal to external equipment as these ports are not required for
feeding the output into the Ultra ’s Analyser/Converter.
To help you select the correct inputs, the ‘input’ versions of the SDI ports that have been selected
as outputs are marked as ‘Assigned to Loopback’, while the ‘output’ versions of these ports are
labelled with the video standard that is being delivered. Please note: to get the required effect, the
entries to pick as the inputs are the ‘output’ version of the ports selected for output. Selecting the
entries marked as being assigned to loopback selects these ports as inputs in their own right. To
alert you to this issue, a message is displayed asking you to confirm that you want to override the
previous connection.
To record the required SDI Input ports:
In the Connections window:
1. Click on the down-arrow at the right-hand end of the first slot of the list of SDI Inputs.
This displays a drop-down list of the SDI inputs,
together with details of how these are currently used.
2. Select, from the drop-down list that appears, the name
of the port you want to use for the cable that delivers
either the whole image (where appropriate) or
Subimage 1.If a message appears that draws your
attention to the current use of the selected port, either
take the option to switch the use of this port or pick a
different port as required,
3. If the image comprises two or more Subimages, repeat
the above steps in order to assign the ports
you will be using for Subimages 2, 3 & 4 to the
second, third and fourth slots in the list.
