Intuition XG
MasterConfig
1 Enable pre-roll in the general settings. Intuition XG requires it to function properly.
2 In the ‘Intuition XG’ page, check the ‘Program’ box and, if your XG box has 2 channels, also
check either the ‘Preset’ box or the ‘Preview box’.
3 Assign IP addresses to ‘program’ and ‘preset’ or ‘preview’. If they use a single XG processor,
use the same IP address. If you have not checked the ‘Program’ box, the checkboxes for pre-
view and preset are dim (disabled). If you do not check the ‘Preset’ (or ‘Preview’) box, no
options appear for preset (or preview).
4 Assign “Oxtel” ports. Use 5006 for program and 5007 for preset. These are predetermined by
the Intuition XG processor.
5 Choose a keyer for the ‘program’ channel and choose a (different) keyer for the preset (or pre-
view) channel.
If you have a two-channel XG processor, the program keyer must be keyer 3 and the preset
keyer must be keyer 2. (Note that these are both post-squeeze in the effects ordering.)
If you have a single-channel XG processor, you may use any of the 3 keyers. (Keyer 1 is pre-
squeeze.)
S
Master control supports up to 4 XG layers. Each layer can be assigned an XG media clip
identifiable by a “recall ID.” The clips mix with the MCE’s program video through the key-
ers assigned to the XG channels. In an MCE configured for Intuition XG, those keyers are
not available as independent keyers.
6 Specify the SWB input ports for each channel. (These belong to an SWB input backplane. The
SWB input card and backplane are required for Intuition XG.)
These inputs receive the fill and key video signals from the Intuition XG processor.
7 Specify the XMS port as 14050 (predetermined by the Intuition XG processor) for the proces-
sor(s) you have identified by their IP addresses. Specify the keyer behavior (disabled, normal or
clear after preset). It is not likely that you would want ‘disabled’ but it is one of the choices.
8 Specify the pre-roll value as 6 (frames). This is actually not a pre-roll, but a latency. The latency
might vary and might have to be determined through experimentation.
Use a value of 12 frames if your MCE’s video standard is progressive.
9 Specify the audio parameters.
The Intuition XG video signals can include embedded audio (up to 16 channels). The MCE pro-
cesses this audio as an audio over. These are the audio options:
• The number of audio channels (from 2 to 16).
• The default over-to-main ratio of the XG layers. This is simply labeled ‘Ratio’. Panel
operators can adjust the over level and the over-to-main ratio.
• Whether to turn on the audio over automatically when a panel operator presses an ‘XG
layer’ button. This is a checkbox option. (With this option, the over actually turns on when
the keyer that supports the XG channel is on and turns off when the keyer is off.)
S
As with other audio over sources, the XG key’s audio might be non-existent or inaudible. If
that is the case, the over will switch on automatically (when enabled) but present no detect-
able audio.
10 Specify the maximum number of layers.
The lower this value, the better your system performance will be.
