Source Memory
Work Buffer, E-MEM, and Source Memory
When source memory is on, it tracks the work buffer’s source selection for
each bus. Whenever a new source is selected on a bus, the last settings used
by that new source are loaded into the work buffer from source memory.
Source memory settings are automatically updated when corresponding
values in the work buffer are changed. For example, suppose Source 1 has
a clip level of 50%, and Source 2 has a clip level of 70%. Selecting Source 1
applies its last used source memory setting to the work buffer (50%).
Adjusting its Clip level to 40% in the work buffer also modifies the corre-
sponding source memory of Source 1. Selecting Source 2 recalls its last used
source memory settings (70%), not those used by Source 1. Selecting
Source 1 again applies its modified setting of 40%, not its earlier setting or
the setting used by Source 2 (
Figure 43 ).
Figure 43. Source Memory and Work Buffer
Source memory is separate from the E-MEM system, though they are
related to one another through the work buffer. When an effect is learned
to a register, the keyer and video processing settings for the sources
involved are saved to that register. When an effect register is recalled, the
sources selected on a bus will use settings from the recalled register, not
from source memory. This recall changes the work buffer. When source
memory is on, the source memory for each source involved in the recall is
updated with the changed work buffer values, and so each source memory
will initially have the same values as the recalled register. Subsequent
changes to work buffer settings will update the source memory of each
source, but these changes are only saved to an E-MEM register if the effect
is relearned.
