GUIDE TO INSTALLATION AND OPERATION
SDM-874p | 7
• When the pushbutton is pushed once, the LED indicating
the currently selected processing mode flashes red and
green. Subsequent pushes cycle the SDM-874p through
the available operating modes.
The available operating modes are:
• Mode A: direct output – the output signal format matches
the input format
• 60i: the output is forced to 60i
• 50i: the output is forced to 50i
• Mode B: reserved for future use
• 60p: the output is forced to 60p
• 50p: the output is forced to 50p
• Mode C: reserved for future use
• GFX 60p: the output is forced to the selected GFX output
resolution (1920x1200 or 1280x768) at 60p.
• GFX 50p: the output is forced to the selected GFX output
resolution (1920x1200 or 1280x768) at 50p.
The SDM-874p automatically detects the input format. It then
internally invokes the appropriate processing to produce the
result selected by the user controls. Among the processing
modes implemented in the SDM-874p are:
• Progressive Segmented Frame (PsF) video takes a
progressive source and divides the image into two fields
as if it had been an interlaced source. This video mimics
the interlaced format and can be processed accordingly.
The SDM-874p converts P→PsF and PsF→ P.
• The Panasonic Varicam system packages video originated
at various frame rates into a standard 59.94i or 60i output
by adding redundant frames. The original frames are
flagged, allowing the original frame-rate signal to be
reconstituted. The SDM-874p supports Varicam output
flagged at 60, 50, 25 and 24 fps.
