Inserting Titles (Keys)
What is a Key?
On the switcher, you can overlay video containing a title or
other material occupying part of the screen (key) over the
the video displayed on the whole screen (background). The
component that processes keys is called a keyer.
There are four keyers available on each of the M/E and
PGM/PST banks.
(There are eight keyers available on the MVS-6530 PGM/
PST bank only.)
A key is comprised by a signal that describes how the
background is cut out (key source) and the video signal
that is inserted into that space (key fill).
Luminance keys and linear keys
These are keys that cut backgrounds using key sources
generated by differences in luminance (for example, black
and white).
Other keys
Chroma keys (keys that use differences in color), color
vector keys (keys that use differences in color and
brightness), and pattern keys (keys that use wipe patterns)
are available.
Entering Titles using Luminance Keys
