4-2-3 Dynamic Motion Control (DMC) Playback

Overview

DMC playback allows you to vary the playback speed for a certain section of a tape, in variable speed mode (from –1 to +2 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.
