Ultra v2.0a User Guide
B-2
Note the inclusion of a ‘Local User Interface’ block in the central section of the display. This may
be used to display the User Interface to a monitor plugged into the HDMI output by routing the
output from the Analyser/Converter to the Local User Interface then from there out to the HDMI
output (as illustrated in Figure B-1). This is needed in order to display on screen an image of the
video being processed (as described in Section K): the image is displayed at full resolution.
The paths taken are indicated by arrows, shown in two shades of blue:
bright blue arrows
indicate
internal links that you cannot change (e.g. between the Eye input and the Physical Layer Analyser
block), while
lighter blue arrows
indicate internal links that you can change.
The points between which these connections can be made are marked by little squares (the ones
on the left-hand side of each block representing inputs; the ones on right-hand side generally
representing outputs) and links are typically made between a marker on the right-hand side of a
block in one column and a marker on the left-hand side of a block in the next column. (The input
to the Local User Interface is however on the right-hand side of this block for layout reasons.)
The
Ultra has both input and output ports for SDI, DisplayPort (DP 1.2) and HDMI 1.4 but while
all three types of output port are supported in the current version, only SDI inputs and the HDMI
input are currently supported for format conversion, while only the SDI inputs are supported for
analysis. Connections can therefore be made between the output of either the Analyser/Converter
or the Generator and any of the output ports, but at the moment the only connections on the Input
side of the
Ultra
’s operation are the links between the Eye Input and the Physical Layer Analyser
block and between the SDI Input(s) or the HDMI Input and the Analyser/Converter.
On the output side, any of the output ports can be used for the output from either the
Analyser/Converter or the Generator but, at present, the Local User Interface can only be output
on the HDMI output port. (There is no external output from the Physical Layer Analyser block.)
SDI video is delivered over 1, 2 or 4 cables depending on the video format, so the Connections
window caters for up to four SDI input ports and up to four SDI output ports to be picked out for
use at any one time. Drop-down lists of available ports are offered for you to make your selection.
AUX 1, AUX 2 and the EYE port are mono-directional and can only be used as inputs, similarly
SDI4, AUX 3 and AUX 4 can only be used as outputs. SDI 1 – SDI 3, however, are bi-directional
and each can be used either as an input or as an output. The Ultra also has the option of looping
back output on SDI 1 – 4 and AUX 3 or 4 for use as an input. This provides a convenient way of
arranging for the video output produced for example by the built-in Generator to be analysed or
converted to a different format, without the need for any additional cabling (see ‘ Looping Back
Output
’ below).
The SDI Outputs can therefore be chosen from among SDI 1 – SDI 4, AUX 3 and AUX 4, while
the SDI Inputs can be chosen from among SDI 1 – SDI 3, AUX 1, AUX 2, the EYE port plus
‘Output’ versions of SDI 1 – 4, AUX 3 and AUX 4. Where a port has been selected as an output,
the ‘Output’ version of the port shows the video standard that is being transmitted while the ‘Input’
version is marked ‘ Assigned to loopback ’. The ‘Output’ version is the option to pick to achieve
the loopback effect: picking the ‘Input’ version results in a message that asks you to confirm that
want the port to be taken off the list of selected outputs and put on the list of selected inputs. A
similar message is displayed if you select as an output a port that is currently selected as an input.
Note: The AUX 1 and AUX 3 ports and the AUX 2 and AUX 4 ports are paired in much the same
way as the Input and Output modes of SDI 1 – 3 are paired with the result that, for example,
selecting AUX 3 as an output makes AUX 1 ‘assigned to loopback’ and hence not available for
use as a separate input.
At the point that an Input port is selected in the Connections window, there is no requirement for
a video signal to be fed into the port. However, when a signal is fed into any input port, the Ultra
automatically determines and reports the video standard that has been detected.
