Section 1 — Encore System Overview
Sharer PC
The Sharer PC is the PC on which the Sharer is installed. Typically the con-
figuration PC and Sharer PC are the same, but separate PCs can be used.
Routing Basics
Terminology
Area
- An Area is a defined group of Sources and Destinations. Takes are
restricted to connecting Sources and Destinations within the same Area
(unless Tie-Lines are used). Defining multiple Areas makes it possible to
assign the same easily identifiable Source and Destination names (like
VTR_1, VTR_2) for use by different devices at different locations in the
facility.
Breakaway
- A Take operation that switches a Source on at least one Level
that is different from the Sources selected on the other Levels.
Channel
- The communication path used to control the crosspoint group by
the Router Control Engine over a selected protocol such as Serial or
Ethernet paths.
Chop - A variation of a Take command that alternately connects each of two
different Sources to a single Destination (flip-flopping) at a designated
switching rate (the chop rate).
Crosspoint
- An electronic switch that allows a signal to pass from an input
to an output when the switch is closed.
Destination
- The location to which Source signals are routed. A Destination
may include one or more outputs across multiple Levels.
Exclusion Set
- User-determined set of items excluded from control by a par-
ticular control panel. Exclusion sets can be created for Areas, Destinations,
Levels, or Salvos. An exclusion set may be shared by more than one panel.
Flag - A parameter that can be set in a control panel template to control how
a panel operates.
Level
- A grouping of signals of a particular type, such as digital video,
audio right, audio left, Red, Green, or Blue, etc. This grouping becomes an
independently controllable stratum of signals within a routing system.
Matrix
- A configuration of potentially intersecting inputs and outputs. In
routing switchers, a matrix is signal switching hardware configured such
that any input may be switched to any output.
