Jack and all, Thank you for the advice. One more ... I checked State events. smil-customTest? PriorityClass is very difficult to understand for me. Could you ( or someone ) show me the example of following case? (bus, city, rain, every o’clock) Your advice is highly appreciated. Thanks in advance.

An organization which I joined recently has been considering to implement a playlist for Digital Signage system (e.g. Mobile Signage). I checked out that there are some playlist formats on http://en.wikipedia.org/wiki/Playlist I think SMIL is one of big candidate for our use. However I could not find our requirements as follows. 1. Need a non time events. Such as "when Bus stop arrived to 'B'.", "when GPS points to outside of Tokyo.", "beginning of the rain" – these events will be converted to signals. There are multiple possibilities. But I think the best candidate is SMIL State events (which are new since SMIL 3.0). SMIL State is a way to use variables in SMIL, and you could set up your application so that there is an external agent that modifies state variables based on things like GPS location, or which stop the bus is at. You can then trigger to these to have the SMIL presentation react. 2. Priority e.g. lowest priority = sequence of "video-a", "video-b", "video-c" low priority: City changed "video-city", Rain status "video-rain" middle priority: When time comes every o’clock, show "video-clock-commercial" top priority: Bus stop changed "video-arrive to the bus stop 'B'. SMIL has the <PriorityClass> element specifically for this use case. It can be used within an <excl> element to group the alternatives according to priority. Moreover, you can specify whether high-priority events pause the lower priority events they interrupt (allowing them to continue when the high-priority event has completed) or completely replace them. Please tell me how to do that. Or tell me whether SMIL is suite for this purpose or not. Your advice is highly appreciated.
