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 Signal) from Silicon Image and DDC (Display Data Channel) from VESA (Video Electronics Standards Association). DVI-D is a DVI connector that supports digital signals only, and DVI-I supports both digital and analog signals.

SDI — Serial Digital Interface. The 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 either 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 it’s own set of 16 user presets.

PIP: Up to 16 user defined PIP window layout presets can be stored, available for later use. Ten factory default PIP window layout presets come as standard and can be overwritten.

Auto Memory — The automatic saving and recall of input and picture controls for signals that have been previously applied.
