Section Commands
Section commands define the settings of this playlist instance. Current support settings are
region setting and video setting. Although the previous example places the commands
after section headers, it can be placed anywhere in the section. Once the command is
executed, the setting will be in effect until some other commands overwrite it; changing
sections won’t reset the setting. For example,
[PL1:start]
<<VIDEO:ON>>
<video1.wmv>
^[PL1]
[PL2:2007/01/01-MON-12:00:00]
<<VIDEO:OFF>>
^[PL2]
[PL3:2007/*/02-*-12:00:00]
<video2.wmv>
^[PL3]
If the device time is 2006/12/01, the flow will be the following:
1. Hard triggered header (PL1) is triggered because none of time triggered headers has
reached their time yet.
2. Turn on the video output.
3. Play
video1.wmv
4. Jump to section header (PL1) and repeat step 1, 2, 3, and 4 until 12:00:00 on
2007/01/01 is reached.
5. At 12:00:00 on 2007/01/01, section (id=2) is triggered.
6. Turn off the video output and repeat step 5 and 6 until 12:00:00 on 2007/01/02 is
reached.
7. At 12:00:00 on 2007/01/02, section (id=3) is triggered.
8. Error occurred when try to Play video2.wmv, because the video output is off!
From this example, it shows the video on/off commands is persistent no matter which
section is currently executing. Furthermore, it demonstrates a careless design that will
cause device malfunctioning after 2007/01/02 at 12:00:00.
Region Setting
The region setting defines the coordinate of the left-top corner and the size of the display
region. The media file can choose to display in defined region by giving the region id.
Syntax:
<<REGION:{id}:{x},{y},{width},{height}>>
Valid parameter values:
{id} = 0-15
{x} = integer
{y} = integer
{width} = integer
{height} = integer
