RE: About RealPix in SMIL

From everything I've read, it is best to use the media type tag names. So,
if you have an audio file you are to play, use the <audio> tag. (This is
what I remember reading off of both RealMedia and W3C's web sites). The only
reason you'd use <ref> is because you are not sure what media type will be
used, or for generic reasons. 

Since "RealPix" is a RealMedia format, I would go with what they are saying
to use. There is no defined use by the W3C, to my knowledge, about RealPix.
But if you use the <ref> tag, there should be no problem either, since the
rules of SMIL say that <ref> can be used by any of the media formats. If a
SMIL viewer can not read the RealPix format, then they will not display it
(possibly giving an error message).

Another time you may want to use the <ref> tag is for audio that is in video
format (eg. QuickTime *.mov audio files). 

Hope this helps

 I type SMIL following.

    <par endsync="first">
    <ref src="tabioto02.rp" region="RealPix"/>
    <textstream src="tabioto02.rt" region="RealText"/>
    <audio src="tabioto02.rm"/>
    </par>


 I checked my SMIL tag use RealNetworks SMIL Evaluator.
 ( http://www.real.com/devzone/library/creating/smileval/ ) 

 It suggested me, its better to use "img" for RealPix.
 Which is better "ref" and "img" for RealPix?
  (better: I mean right in W3C SMIL RFC)
