Time Limited Links in HTML+TIME

Hi

Can anyone tell me how to do time limited links in HTML+TIME.  For
instance the equivalent of the SMIL

<area href="http://whatever.com" cords="10,10,100,100" dur="15s" />

Also, I read that the SMIL linking module is not implemented in
HTML+TIME since it just uses the trad HTML version.  How then can you
make a time limited hyperlink?

Also, how might internal hyperlinking be supported in HTML+TIME - e.g
the equivalent of

 <area href="#clip3" cords="10,10,100,100" dur="15s" />

Thanks

Steve Bennett

RE: Time Limited Links in HTML+TIME

Basically, you do the same thing as in SMIL language. I just tested it in
IE6 with a sequence of area elements synced to a sequence of text (so I knew
when the areas *should* be active). Works fine. If you have trouble, let me
know and I will post the example to the ludicrum demos site.

Seeking on hyperlinks does not work in IE. You can still do the internal
hyperlinking, but all you get is the spatial seek (scrolls the page). You
can make it work by adding a behavior that does the seeking (e.g. in an htc
or in script onclick handlers for the links). Unfortunately, for non-trivial
cases where you are seeking to elements deep within time containers that are
not active, the logic may be hard to get right. The spec describes it
clearly, but it is work. If you  have simpler cases, then you can use the
time2 DOM to do the seek as you need.

spline animation

From spec:

*********
keySplines:
The values must all be in the range 0 to 1

********

I'm puzzled by this, if I understand correctly, This limits the possibility
to create smooth curves from one value to the next.

I agree that x1 and x2 should be limited to 0..1, but y1, y2 shouldn't have
that limitation.

Am I misunderstanding something?

Access Key & Unicode

Hi all,

I am attempting to implement a system for slide presentation over the web.  I have a main region containing a
sequence of graphics and audio within <PAR> tags, and below that, a region containing a list of buttons
allowing the user to navigate to the various slides within the presentation.

Now supposing the number of slides was greater than 10, how could one implement access keys for those
buttons?  Now on windows platforms if you press on the alt key and then do a sequence of numbers you can
produce characters to appear on screen. I'm wondering if that would work for me (e.g you could press ALT+17
and that would take you to slide 17).

Below is what alt + 1 to 10 looks like

☺☻♥♦♣♠•◘○◙

(I'm not sure if the mail relay will reproduce what I see before me but it is essentially)

a smiley with the fill white and the line black
a smiley with the fill black and the line white
a heart symbol
a diamonds symbol
a clubs symbol
a spade symbol
a dot
a white dot inside a black square
a circle with fill white and line black
a white circle enclosed within a black square

Anyway, my question is, does anyone know how to implement access Keys for non standard ascii characters?

RE: Access Key & Unicode

Hi Steve - 

I do not know what the SMIL Language players do, but accessKey support is not in IE (XHTML+SMIL includes it,
but IE does not support it).

I would think that an easier UI would include a TOC panel with a list of slides (e.g. by title), and then
hyperlinks or event-based timing that shows the associated slide.  You can even have that whole TOC hide
and show on a small button if you are concerned about real-estate. I have done this in IE for my own slides (I
use a simple XML schema for slides and then have different XSLT stylesheets to create the presentations).

Good luck - Patrick

Hi,

Following up on my previous question, would it be correct to nest <par>
tags used simply as a grouping mechanism?

For example,
<par>
	<audio ....>

	<!-- pseudo grouping 1 -->
	<par>
		<image begin="0" dur="3"...>
			<transitionFilter.../>
		</image>
		<animation begin="0" dur="3"...>
			<transitionFilter.../>
		</animation>
		<text begin="0" dur="3"...>
			<transitionFilter.../>
		</text>
	</par>

	<!-- pseudo grouping 2 -->
	<par>
		<image begin="2" dur="3"...>
			<transitionFilter.../>
		</image>
		<animation begin="2" dur="3"...>
			<transitionFilter.../>
		</animation>
		<text begin="2" dur="3"...>
			<transitionFilter.../>
		</text>
	</par>

	...etc

</par>

So we have an audio stream playing in parallel with 'groups' of other
media items which are roughly in sequence, but written in parallel (by
the top level par tag) to facilitate transition effects between the
'groups'

I am evaluating the potential of SMIL as a data format for a project I
am working on and so I am interested in what the language allows. I
think some kind of generic 'group' item, or meta data group tag, would
be useful in situations like this, however, as there does not appear to
be one within SMIL, is the above the correct approach?

Thanks
~Colin.

Proposal on SMIL 2.0 Extension

Dear All,

I'm pleased to inform you that our Submission request on SMIL 2.0
Extension[1] has been acknowledged and published by W3C[2].

[1] http://www.w3.org/Submission/2003/04/
[2] http://www.w3.org/TR/SMIL2-AuthExt/

------------------------------------------------------------------------
Abstract:

This submission is a proposal for resuming SYMM Working Group to improve
SMIL 2.0 Specification.

Originally SMIL was designed for describing interactive multimedia on
the Web. However, this proposal intends to seek out the possibility of
SMIL for professional multimedia authoring. Introducing SMIL-based
content authoring into professional multimedia production is also
expected to enhance the possibility of SMIL-based contents on the Web.

Depicting a number of requirements for professional multimedia authoring,
possible solutions are proposed by improving existing function modules
and appending additional function modules. Lightweight profiles are also
important to keep conformance between wide variety of authoring
functionality.
------------------------------------------------------------------------

I believe some of you on this ML already familiar with this because
originally I made a presentation of this idea at SMIL Europe 2003 in
February.  Now I would like to call your attention on this ML to our
proposal.  

We are still making continuing efforts to introduce SMIL-based XML
language to multimedia authoring systems.  That is expected not only to
change professional content production and content delivery, but also
expand the market of SMIL application.

I would like to encourage those who are interested in developing the
future possibility of SMIL to be involved in the discussion and future
working of SMIL.

I will be so glad to have your comments, suggestions and any interests.

It would be great to see those with the resources to take advantage
of what SMIL does to Multimedia. SMIL can take separate media files
and present it as one, but it also can allow the viewer to choose
and customize the audio/visual experience. An analogy would be
a restaurant customer choosing the foods that pleased their senses of
smell and taste, a Multimedia viewer watching a SMIL movie could now 
choose the audio and visual selections that would please those senses.

Choice is Good :)
