Matrix 3200/6400 Series • Reference Information
SVHS – A high band video recording process for VHS that increases the picture
quality and resolution capability. See S-Video.
S-Video – The composite video signal is separated into the Luminance (Y) and
the Chrominance (C).
Terminal – A device typically having a keyboard and display that is capable of
sending text to and receiving text from another device, a network, etc.
Termination – A load, or impedance at the end of a cable or signal line used to
match the impedance of the equipment that generated the signal. The
impedance absorbs signal energy to prevent signal reflections from going
back toward the source. In the video industry, termination impedance is
typically 75 ohms.
Vertical Interval – The synchronizing information which is presented between
fields, and then signals the picture monitor to return to the top of the screen
to start another vertical scan.
Videoconferencing — Conducting a conference between two or more locations
using video cameras, microphones and video monitors. The participants can
be seen, as well as heard. Referred to as a “virtual conference room”.
Virtual conference room — See videoconferencing.
Virtual map — Used with Extron’s virtual matrix switchers (Matrix 3200/6400), a
virtual map is made up of tables stored in memory that relate physical
connectors (as on the back panel) to logical connections (as seen by the
user). In printed form, this can show physical input/output connector
numbers as they relate to virtual input/output numbers.
Virtual memory — The process of increasing the apparent size of a computer’s
random-access memory (RAM) by using a section of the hard disk storage
as an extension of RAM.
Virtual switching — A means of making real, physical input or output ports
appear to have different numbers. For example, Extron’s Matrix 3200/6400
switchers can be programmed to switch a set (group) of connectors as one.
Also see virtual map.
Wideband – A relative term indicating a high bandwidth.
Y – In video, “Y” is an abbreviation for Luminance.
Z – A symbol for impedance.
