|
|
<p class='phone'><cite>raphael:</cite> section 3.1 figure
|
|
explains context, but the last row "example image track"
|
|
illustrates that we can take a blob of an image, but the text
|
|
doesn't consider this</p>
|
|
|
|
<p class='phone'>raphael, case, eg. spatial regions of
|
|
images</p>
|
|
|
|
<p class='phone'>phillip suggested we specify that we also
|
|
support spatial ranges</p>
|
|
|
|
<p class='phone'><cite>jack:</cite> what is the difference
|
|
(from our point of view) between text and image track?</p>
|
|
|
|
<p class='phone'>i think the overlapping content is the main
|
|
thing</p>
|
|
|
|
<p class='phone'>so for temporal addressing there can be
|
|
multiple text elements which match a temporal region</p>
|
|
|
|
<p class='phone'><cite>jack:</cite> for this draft perhaps we
|
|
should only specify audio+video</p>
|
|
|
|
<p class='phone'>and chasing dependencies of previous text
|
|
elements (ie. working out which are active now) can be more
|
|
difficult than eg. video keyframes</p>
|
|
|
|
<p class='phone'><cite>raphael:</cite> we should publish,
|
|
including these minor changes</p>
|
|
|
|
<p class='phone'><cite>jack:</cite> editorial note by silvia is
|
|
a question to the reader<br />
|
|
... editorial note by dave singer, needs to be addressed (sec
|
|
3.12)?</p>
|
|
|
|
<p class='phone'>"The fallback plan needs to be clarified. We
|
|
must be able to handle the way the # is already used, e.g. in
|
|
YouTube, without breaking what is already working."</p>
|
|
|
|
<p class='phone'><cite>raphael:</cite> the wg. has discussed
|
|
that we need to be backwards-compatible with existing
|
|
implementations as much as possible</p>
|
|
|
|
<p class='phone'>eg. youtube syntax, and we are still
|
|
discussing what the behaviour should be</p>
|
|
|
|
<p class='phone'>so is the vague phrasing of compatibility with
|
|
"widely implemented solutions" enough?</p>
|
|
|
|
<p class='phone'><cite>raphael:</cite> we have already
|
|
discussed that eg. the youtube way could be a different syntax
|
|
we specify, with explicity hms</p>
|
|
|
|
<p class='phone'><cite>jack:</cite> ok then we should add a
|
|
sentence about that, and a note to suggest that parsers
|
|
recognize foreign syntax and stay away from it<br />
|
|
... so if we draft a paragraph and send it to dave, see what he
|
|
thinks</p>
|
|
|
|
<p class='phone'><cite>raphael:</cite> ok, but also that is not
|
|
blocking the publication of documents</p>
