Source Memory Organization
Each source on each Zodiak bus has its own source memory. Source
memory parameters for each source are organized into groups to allow
some settings to be remembered and applied independently to meet dif-
ferent requirements (
Figure 44. Source Memory Organization
Because a Zodiak source may have two signals (key cut and key fill), dif-
ferent groups of source memory parameters are associated with each
signal. The Zodiak system key buses always have key cut and key fill sig-
nals. The background A and B buses that do not have key cut signals do not
use the key cut group of source memory parameters.
Source memory for the key fill signal has video processing (proc amp)
parameters, and also specifies which key cut signal to use. Source memory
for the key cut signal contains all the keying parameter settings. Some of
these keying parameters are in turn organized into four subgroups, or key
modes. These modes correspond to linear key, luminance key, chroma key,
and preset pattern. A parameter specifying which of the four modes is
being used is included in the key cut portion of source memory. This means
with source memory on, selecting a source with a key fill and a key cut
signal will automatically apply any proc amp settings to the key fill, select
the last used key cut signal which specifies the key mode, and the last used
