buses and provides transition (mix and wipe) and keying capabilities on
the selected signals.
A simple basic ME used in a typical switcher will be used as an example in
the following discussion. A Kayenne ME has added capabilities, but the
basic principles described here will apply. See Section 1 - System Overview
for a simplified diagram of the actual Kayenne ME architecture.
Figure 11. Simplified Mix Effects (ME) Subsystem
has an A and a B background bus. These
buses select the background video signals sent to the output of the ME.
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 ME 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. See Transitions
for more information. The processed signal in
an ME is then sent to an ME output, typically program or preview.
Each Kayenne ME actually is able to produce up to six outputs (Program A,
Preview A, Program B, C, D, and Preview 2 that is shared by the three addi-
tional program outputs). These additional outputs allow great flexibility in
configuring a Kayenne system for special purposes.
Logical Assignments of MEs
A video production switcher can have more than one ME. For example a
4.5-ME Kayenne system has five (ME 1, ME 2, ME 3, ME 4 and PGM PST).
A 4.5-ME frame consists of four full ME cards, A, B, C, and D and the stan-
dard Half ME (ME 50). Any frame ME can be assigned to the logical MEs
by using the Eng Setup, Acquire Resources menu. ME 50 could be assigned
as ME 2 or later assigned as PGM/PST on a show-by-show basis. Any of
the frame’s MEs can be assigned to one of the five logical Kayenne MEs.
