Re: Unifying scheduled and event-based content timing

Dear Futomi and all,

Thank you for your comments.

I agreed with you in that the proposal is covered to R1, mark-up based
control of contents. It covers a lot.

However, the proposal is not to achieve event-based contents using a
declarative approach.

It's about integrating event-based content timing to pre-determined content
time schedule.

Let me give an example.

Advertisement A is scheduled to be displayed on a digital signage at 1 PM.
It is paid for 1 hour display (from 1 PM to 2 PM)
Advertisement B is also scheduled to be displayed just from 2 PM to 3 PM.
A user comes to the signage at 1:55 PM. He tries to play an movie clip
pertaining to the advertisement A. The duration of the movie clip is 10 min.

Do we allow him to activate the movie clip?

If we allow him to play the movie,
1) stop the movie at 2 PM  and display the advertisement B thereafter.
2) continue to play until the end of the movie and start the advertisement
B thereafter.

Else,
3) not allow him to play the movie.

In this case,
the advertisement A and B are scheduled in advance to play on time, but the
movie clip is only activated by user events, such as clicking or touching
the signage.
It is required to integrate those two different types of content activating
methods(scheduled vs. event-based content timing).

This issue was already discussed in SMIL 3.0. I think it should be also
considered in our document.

How do you think?

Sincerely,

Gisung Kim
