Glossary of Switcher Terms

DVE (Digital Video Effects) — A special effects generator with the ability to create PIP effects, reduce and enlarge images, create borders and shadows around those images, and create keyframes for motion paths. See PIP and Keyframe for additional information.

EXT (External) — A digital key input that is dedicated to the DSK.

Fader — see T-Bar.

FTB (Fade to Black) — The button which enables the TD (Technical Director) to fade everything on Program, including the DSK, to or from black.

GPIO (General Purpose Input/Output) — One or more communications ports that control input and output "triggering." For example, with a GPI (input) trigger, an external peripheral device can trigger a specified switcher function. With a GPO (output) trigger, the switcher can trigger an external device.

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.

Keyframe — In a PIP “move,” a keyframe is a point where an action or change occurs. For example, when a PIP moves from the upper right corner to full screen, keyframe 1 is the upper right position, and keyframe 2 is the full screen position of the PIP.

Keying — The process of superimposing video from one source (the foreground) on top of another source (the background).

Key Fill — The video which fills the hole cut by the keying circuitry. Typically, switchers provide a variety of choices for the fill source — internal mattes, external video, or "self" fill are several examples.

Key Mask — A key modification system that protects a portion of the foreground video from being keyed, using the switcher’s internal pattern system.

Key Signal — also known as Key Source. The signal that electronically cuts the hole in the background video signal. Key signals typically originate from external inputs such as character generators or cameras.

Linear Key — a keying mode in which the edges of anti-aliased key sources (such as character generators) are reproduced clearly. Typically, two separate signals are required from a linear key source: a cut and a fill.

M/E (Mix/Effects) — The section (or "bank") of a video switcher where video signals are processed to select inputs and create mixes, wipes, keys and other effects. An M/E is essentially a video layer that can be combined with other M/Es (layers) to form the entire output of the switcher.

Menu — A term used to describe buttons and functions on the high-resolution color LCD touch screen.

Mix — also known as a Dissolve. A transition between two video sources in which one source fades out as the other fades in.

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, e.g., SD-SDI (SMPTE 259M, Level C) or HD-SDI (SMPTE 292M).
