Controlling udp output from an interactive playlist To control udp output for a particular state, add a udp command to the second column of the state specification in the interactive playlist. When BrightSign enters the udp state, the specified string is output via the ethernet connector. The format is: udpSend: Preloading images The autoplay script preloads still images so that appear automatically when a user triggers their display. Here are the rules that apply to preloading an image: • If a state row only has one possible next image state, then the next image is preloaded. • If a state row has more than one possible next image state, and one of them is the next row in the state table, then the image associated with the next state is preloaded. Therefore, if you have a sequence of images that display one after the other and you want them to preload, put them in sequential rows in the state table. To see an example of this, look at the BS1.BMP, BS2.BMP, etc. state rows in the interactive playlist demo. 37 • •

Controlling udp output from an interactive playlist
To control udp output for a particular state, add a udp command to the second column of the
state specification in the interactive playlist. When BrightSign enters the udp state, the specified
string is output via the ethernet connector. The format is:
udpSend:<string>
Preloading images
The autoplay script preloads still images so that appear automatically when a user triggers their
display. Here are the rules that apply to preloading an image:
•
If a state row only has one possible next image state, then the next image is preloaded.
•
If a state row has more than one possible next image state, and one of them is the next row in
the state table, then the image associated with the next state is preloaded. Therefore, if you
have a sequence of images that display one after the other and you want them to preload, put
them in sequential rows in the state table. To see an example of this, look at the BS1.BMP,
BS2.BMP, etc. state rows in the interactive playlist demo.
