Switcher Control
Basic E-MEM Operations
The E-MEM (Effects Memory) system provides 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.
The GV Switcher system has 1000 E-MEM registers organized into Pages and Banks. There
are ten pages of ten banks with 100 E-MEM registers each, that can be learned and recalled
from the menu or in the Local and Master E-MEM areas.
Register operations such as Learn and Recall can be performed in the current page and
bank or changed before selecting the desired register.
Time Value Entry
Time values are input on the GV Switcher Control Panel Local E-MEM and Master E-MEM
areas in seconds, frames, odd field format, using the • button the separator (indicated below
as “•”) and pressing the hard button below “Enter” in the display to complete the entry:
(seconds), •, (frames), •, (field), Enter
The default time entry is in frames. For example, a time of 15 frames (one half second on 60
Hz systems) can be input simply by pressing:
15, Enter
Entries in seconds can be entered by adding one separator. For example, a time of 1 second
is input by pressing:
1, •, Enter
An odd field is input by pressing 1 as the last entry. For example, a time of one second 15
frames and one field is input by pressing:
1, •, 15, •, 1, Enter
After an odd field has been entered, it is represented with an “f” in the E-MEM readout. For
example, the completed time above appears as 1:15f. It is possible to enter values other
than 1 as an odd field. The system will calculate and display the correct number frames and
a single odd field.
To enter only fields, use two separators before the number. For example, a time of 30 fields
(one half second on 60 Hz systems) is entered by typing:
•, •, 30, Enter
Pressing the • button first resets the effect duration to the Natural duration.
