2.6.5. Video Inhibit
The Video Inhibit function may be assigned to one of the automation pins through the XD20 setup
menus. See the information on
Pin Definitions
on page 81, to define these pins.
The XD20 will not start video playback as long as the video inhibit signal is active. The XD20 will also
stop video playback immediately if this signal becomes active during the video playback.
2.6.6. Video Playlist Automation Sequence
2.6.7. End of Playlist
At the start of the playlist, a “Lamp on” command is immediately sent to the video projector through the
serial port. The first video clip can be delayed, programmable from 0 to 120 seconds after the start, to
allow the lamp to warm-up. A start pulse output may be programmed to occur from 0 to 120 seconds after
the “Playlist start” command.
For video clips with audio, the XD20 will trigger the cinema processor to switch to the DTS format. For
video without audio, the XD20 triggers the cinema processor to switch to the silent video format. These
formats are programmable through the XD20. The format pulse occurs only at the transition from audio to
no audio, or vice versa.
The XD20 may be programmed to send an end pulse near the end of the playlist. The end pulse timing
may be programmed to occur from between 60 seconds before to 60 seconds after the end of the playlist
(negative end pulse). The negative end pulse is useful for triggering a film projector to ramp up before the
playlist ends, so that the film starts immediately after the playlist ends. In cases where the playlist is
shorter than the negative end pulse offset, then the end pulse will occur at the playlist end.
The XD20 may be programmed to turn off the video projector at the end of the playlist. The XD20 may
also be programmed to switch the cinema processor to a predefined sound format at the end of the
playlist.
