Definitions
The following terms are used throughout this manual:
EDID — Extended Display Identification Data. A communications protocol or instruction
set developed by VESA (Video Electronics Standards Association) for the identification of
display devices to computers using the DDC (Display Data Channel) transmission standard.
DVI — Digital Visual Interface. The digital video connectivity standard that was developed
by DDWG (Digital Display Working Group). This connection standard offers two different
connectors: one with 24 pins that handles digital video signals only, and one with 29 pins
that handles both digital and analog video. This standard uses TMDS (Transition Minimized
Differential Signaling) from Silicon Image and DDC from VESA. DVI-D is a DVI connector
that supports digital signals only, and DVI-I supports both digital and analog signals.
SDI — Serial Digital Interface. A standard definition video transmission standard based on
a 270 Mbps transfer rate. This is a 10-bit, scrambled, polarity independent interface with
common scrambling for both component ITU-R 601 and composite digital video and four
channels of embedded digital audio.
HD-SDI — High-definition version of SDI specified in SMPTE 292M. This standard
transmits audio and video over a single coaxial cable with a data rate of 1.485 Gbit/
second.
Preset — A configuration that has been stored, allowing the setup and recall of recurring
I/O configurations using the front panel, RS-232/422, or Ethernet control.
• Input – Up to 128 input presets (individual I/O configurations) may be saved and
recalled. An input preset is a user-defined set of input and picture control settings that
can be saved for each source within a system so that they can be recalled whenever
the source is active. Input presets can be recalled on any input that supports the saved
input’s video format. This type of preset saves specific settings for size, centering,
contrast, brightness, detail, zoom, and input configuration. Unlike user presets, input
presets save parameters that can be recalled only on the source that was active when
the preset was saved.
• User – Up to 16 user presets per input are available. A user preset saves specific
settings for color, brightness, detail, size, and centering. User presets are used when
a shortcut is needed to quickly recall a group of settings that relate to the current
content or current input. Each input has its own set of 16 user presets.
Auto Memory — The automatic saving and recall of input and picture controls for signals
that have been previously applied.
