Recognizing the appearance of improperly shaped video helps you know
how to correct the problem should it occur.
E-MEM (Effects Memory)
Grass Valley Group developed the E-MEM (Effects Memory) system to
provide a way of storing effects for later use. An effect defines parameter
settings that determine how the selected video sources are processed. An
E-MEM effect is learned into an effect register, and can then be recalled at a
later time with a single button press. Effects can be edited after they have
been learned, and effect data can also be saved to and loaded from disk.
Work Buffer
The work buffer is a fundamental aspect of system operation. The work
buffer contains the current state of the system, specifying the sources
selected and the video processing applied to those sources. The work buffer
tracks all the system parameters, including those that do not have controls
delegated. As the operator delegates and alters control panel and menu set-
tings, the associated parameters in the work buffer change. If any altered
work buffer parameters affect the video outputs of the switcher, the
appearance of these outputs will change accordingly.
