2.6.1.1. Slide-loop Playlist
The slide-loop is a special type of playlist that may be played before the Preshow playlist. The slide-loop
is a series of images, video clips, and audio clips that continuously loop until the Preshow playlist starts.
The Preshow playlist may be started by menu, automation, or an automated start time determined by the
video configuration. When the Preshow start is given, XD20 finishes the current clip of the slide-loop
before beginning the Preshow playlist.
2.6.1.2. Preshow and Intermission Playlists
The Preshow playlist is normally shown before the film starts. The Intermission Playlist is normally
shown during the film intermission period. The timing of automation events may be programmed
individually for both types of playlists.
2.6.1.3. Playlists C through G
Playlists C through G do not have a predefined purpose. They are available if there is a need to have
separate playlists. The timing of automation events may be programmed individually for each of these
playlists.
2.6.1.4. End Slides
In some cases, an “end slide” is used as the last clip in the playlist. When the end slide is used, the playlist
does not automatically stop. Instead, the image continues to appear until XD20 receives the video Stop
command, or the Video Inhibit signal.
2.6.2. Start and Stop Video Playlists
There are two ways to start and stop video playlists: using menu commands or using automation.
Start and Stop Video with Menu Commands
XD20 menus may be used to start or stop a video playlist. See Playback Menu on page 23, for details.
Start and Stop Video through Automation
Functions to start and stop the video are also available through automation commands. The function must
be assigned to one of the automation pins through the XD20 setup menus. See the section on
Pin
Definitions on page 81, for reference.
2.6.3. Preshow Playlist Schedules
The Preshow playlist schedule is defined by the video configuration file. The playlist schedule determines
which playlist will be shown, based on time and date. For example, the configuration file may define a
different playlist for the Preshow playlist when the playlist starts at night than when it starts during the
day. In order for the scheduling to be correct, the date and time for the XD20 clock must be set correctly.
If the XD20 Media Player is connected through the network and has a network time server configured,
then the clock is automatically set by the program. Otherwise, the clock must be set through the menus.
The clock battery must be replaced every few years (and the system clock must be reset) if the
XD20 unit is not connected to a network containing a Network Time Server.
