3.7 Terminology
Terms used in this Vega 30 Router User Manual are listed and defined in the table below:
Term
Definition
Association
A logical grouping of sources, or of destinations, which allows
several signals to be routed together. These are normally of
different signal types e.g. audio channels associated with a video
source.
Association Routing
Routing using associations, i.e. associated sources and associated
destinations.
Audio Channel Source
Sources for each audio channel in a source association.
Audio De-mux Point
Internal node within a Vega 30 router. Provides access to the
embedded audio in the video crosspoint outputs.
Channel
A signal may be a composite of several signals or channels.
For example, the 16 embedded audio channels in a video signal.
Clean switch
A switch transition resulting in a signal waveform with no or minimal
disturbance in the switched signal waveform.
Crosspoint Switch
(Crosspoint)
The switching component of a router.
There can be more than one crosspoint switch.
For example, video crosspoint and audio crosspoint.
Destination
An output of a crosspoint.
Direct Audio Routing
Routing the audio crosspoint, using source and destination port
names or fixed numbers, not using associated sources and
destinations.
Direct Video Routing
Routing the video crosspoint, using source and destination port
names and fixed numbers, not using associated sources and
destinations.
Follow Video
A type of audio channel source which gives automatic access to
the embedded audio in a routed video signal.
Input
Router input connection.
Line Sync
(Line Synchronizer)
A feature which aligns the timing of video signals.
Lock Route 1:1
Setting Lock Route 1:1 guarantees the presence of input video at
the corresponding output of the
video crosspoint.
Used to give
audio routing direct access to the input embedded audio.
MADI
Multichannel Audio Digital Interface
Null Source
A video or an audio channel source of ‘null source’ has no effect
when routed.
Output
Router output connection.
