Dynamic Motion Control (DMC) Playback
Overview
DMC playback allows you to vary the playback speed for a certain section
of a tape, in variable mode (from −1 to +1 times normal speed), and store
the varying speed in memory for later playback at the same varying speed.
For example, during a live broadcast of a sporting event you can set the
start and end points of highlights while recording, and then provide
immediate DMC playback of those highlights.
During DMC playback the tape moves as shown in the following figure.
