däçëë~êó=çÑ=pïáíÅÜÉê=qÉêãë=
The following terms and abbreviations are used throughout this guide:
•
3G — A 3 Gbit/s serial digital 10-bit or 12-bit video interface (SMPTE 424M and
425M).
•
AUX (Auxiliary) Bus — AUX buses are extra switching buses that allow video
signals connected to the switcher to be routed to external equipment such as
VTRs, monitors, projectors, etc.
•
Chassis Cards — The following cards are installed in the chassis:
~
1 M/E (Mixer/Effects Card) — provides crosspoints to route inputs to
outputs.
~
1 System Card — provides CPU, system memory, and still stores.
~
5 UIC (Universal Input Card) — provides two universal scaler inputs per
card.
~
2 SOC (Standard Output Card) — provides two universal auxiliary
outputs per card.
•
Computer Video — A generic term indicating video that originates from a
computer platform. A progressive scan signal that follows VESA (Video
Electronics Standards Association) standards, with typical resolutions of 800 x
600, 1024 x 768, 1280 x 1024, etc.
•
Crosspoint — The video switch (or button) that selects the input required on a
particular switcher bus.
•
Cut — an instantaneous switch from one video source to another.
•
DA (Distribution Amplifier) — A video device that inputs one video signal, and
outputs multiple “identical” signals.
•
Enables — Within a Module , Enables are arrays of sub-functions that can be
toggled on or off.
•
GUI (Graphical User Interface) — A term that describes a status display based on
graphics and icons, rather than strictly on numbers and letters.
•
HD-SDI (High Definition Serial Digital Interface) — a high definition SDI signal
(SMPTE 292M). Example formats are 720p, 1080i, and 1080p.
•
LTC — Longitudinal Timecode, an encoding of SMPTE timecode data in an audio
signal, as defined in SMPTE 12M specification.
•
Menu — A term used to describe buttons and functions on the GUI.
•
Module — A column in the Memory Menu ’s table of registers.
•
Multiviewer (MVR) — a monitoring system that enables multiple sources (input
and outputs) to be displayed on one or two monitors, eliminating the need for
individual source monitors. By utilizing different arrays of PIPs, users can select
the preferred multiviewer “look,” and streamline control room operations.
•
Native Resolution — The resolution to which all processing is set within the
switcher frame.
•
PGM (Program) — The on-line (or on-air) output from the FSN switcher.
•
PVW (Preview) — The off-line (or off-air) output from the FSN switcher used to
show content that can be transitioned to Program.
•
RGB — The red, green and blue color signal components.
