Data Field Format
All time data (field count) and speed data is specified to be binary data in
S15.16 format. The lower two bytes specify a fractional field value. The
topmost bit is the sign bit and the next 15 bits represent whole field values.
Note the following examples.
+1 field : 00 01 00 00
– 1 field : FF FF 00 00
+1 (unity) speed : 00 01 00 00
– 1/2 speed : FF FF 80 00
Setting the Run Time for a speed of zero is the same as sending a STOP com-
mand.
The editor is allowed to write a negative field count or to trim in a negative
direction which results in a negative field count. In either case the result is
to display a negative timecode in the menu and position the video at the 1st
