Source Memory

Figure 81. Default Keyframe

The operator can define exactly what these default settings should be (Suite
Preference), and these settings can be stored and reused to meet varying
requirements. A separate set of factory default settings also exist that
cannot be changed, but may be loaded to the Default Keyframe and then to
the work buffer, typically for system test and initial system installation.

Source Memory

Source memory is a Kalypso system feature that retains the last settings of
keying and video processing parameters used for each source on each bus.
Source memory permits the operator to hot cut from one key to another and
retain the settings for each source. Source memory keying settings include
Clip, Gain, Borderline, Mask, and many other parameters used for various
keying functions. Video processing (proc amp) settings include Lumi-
nance, Chrominance, DC Offset, etc. The source memory feature can be
turned on and off by the operator.

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
