Mix/Effects (M/E) Stage
Each M/E of the Kayak system can create a composite of two or more pic-
tures. It includes multiple source selection buses and provides transition
(mix and wipe) and keying capabilities on the selected signals.
The M/E can be organized with the keying circuitry separate from the
mixing circuitry, which permits Effect Send capabilities (see
Effects Send
on
page 43
for more information).
A simple basic M/E used in a typical switcher will be used as an example
in the following discussion. The Kayak M/E has added capabilities, but the
basic principles described here will apply.
Figure 15. Simplified Mix Effects (M/E) Subsystem
The basic M/E shown in
Figure 15 on page 42
has an A and a B background
bus. These buses select the background video signals sent to the output of
the M/E.
Generally the source on the background A bus is the current background
output, and the source on the background B bus is the background video
that will be used next. During most transitions, portions of both back-
grounds are output simultaneously. The keyers in the M/E allow the inclu-
sion of additional material over the background. Wipe generators also
exist, which create patterns used by the mixer for wipe transitions, or used
by the keyers to modify the signals it sends the mixer.
The processed signal in an M/E is then sent to an M/E output, typically
program or preview (or can be selected as input in the second M/E).
Alternate Buses and Delegation
Many earlier generation switchers had M/Es equipped with two keyers,
and each M/E could accept two background sources. This permitted
mixing or wiping between two backgrounds, and keying up to two addi-
tional sources over the background. Dedicated rows of control panel
buttons were used to select these key and background signals.
