The CSS playback works the same as DTS feature audio playback, in the sense that the film contains
timecode that must match the assigned film and audio serial numbers. This prevents playback of the
wrong content with the wrong feature.
The projectionist threads the film through the D600 Timecode Reader Head on the projector, and when
the show starts, the CSS will play automatically, synchronizing the content to the film. Some operational
tasks can be performed by the projectionist. These are explained in more detail under
Playback Menu
, in
Chapter 3.
