MAESTRO Installation and Service Manual 67
Customer Requirements
Router Control
Encore is connected using Ethernet LAN.
Jupiter is connected using either Ethernet LAN (CM-4000) or serial cable
(VM-3000).
Prelude is connected using Ethernet LAN.
Router type
All Maestro systems require the use of a GV-controlled matrix router (there
is no “internal matrix” option).
If a Concerto board is installed in a Maestro/Concerto frame, it should be
understood that there are no inter-frame connections between the Maestro
board(s) and the Concerto board(s) other than a power bus. Video, audio,
LAN, etc. cables must therefore be installed to connect Concerto rear panels
to Maestro rear panels.
Keyers
All systems include four key inputs. Keys can be inserted “upstream”
(paired with the background video) or “downstream” (not affected by
background video transitions).
Note Maestro includes eight keyers. Sources from the four key cut/key fill inputs
may be assigned to any of the eight keyers; however, only four keyers can be
on air simultaneously. A future branding engine option will provide internal
storage of additional key sources which may also be assigned to any of the
eight keyers. With the branding engine installed, it will be possible to have all
eight keyers on air simultaneously.
When a key is operated in “external” mode (that is, using a fill signal with
a cut signal), the fill and cut connectors are operated as fixed pairs. For
example, KF1 (Key Fill 1) will always be paired with KC1 (Key Cut 1), KF2
will always be paired with KC2, etc. See
Figure 34 on page 86 . Typically, the
key and fill signals arrive from a Maestro-controlled router, and the Key Fill
Association table is used to configure the Key/Fill pairs. For example, if a
character generator fill signal is selected for KF1, the CG’s cut signal will be
routed automatically to KC1.
If instead the key signals do not pass through a Maestro-controlled router,
they are referred to as “direct key” inputs; in this case the operator must
manually switch the fill and key signals to the appropriate connector pairs.
For example, if the fill signal is switched to KF1, then the cut signal must be
switched to KC1. (Unlike Saturn, there is no special configuration entry to
permit other associations such as KF1 to KC2, etc.)
