    <p class='irc'>&lt;<cite>Yves</cite>&gt; file always get the
    full result, so identifying fragment forces seeking</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; 4. RTSP

    http://www.w3.org/2008/WebVideo/Fragments/wiki/RTSP_implementation</a></p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; Davy: I describe
    how to address a track and a temporal fragment in rtsp</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; ... some feedback
    would be nice</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; ... is there any

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; Jack: I will read

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt;
    <strong>ACTION:</strong> Jack to review the RTSP implementation
    document [recorded in <a href=
    "http://www.w3.org/2008/11/05-mediafrag-minutes.html#action03">http://www.w3.org/2008/11/05-mediafrag-minutes.html#action03</a>]</p>

    <p class='phone'>5. existing technologies survey (erik)</p>

    <p class='phone'><cite>raphael:</cite> merge this to the state
    of the art page</p>

    <p class='phone'><cite>erik:</cite> I can only look at it from
    15/11/2008<br />
    ... it will be ready at second F2F</p>

    <p class='phone'><cite>Guillaume:</cite> how to give feedback

    mailinglist<br />
    ... provide the version you have reviewed<br />
    ... give comments section per section</p>

    <h3 id="item05">Issues</h3>

    <p class='phone'><cite>raphael:</cite> caching discussion<br />
    ... time ranges is really hard</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; Jack: i think time
    is complex and cache should not necessary try to understand
    time ... thus only cache bytes range</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; Davy: I do not say
    exactly the contrary, but i'm arguing about implementation</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; Jack: caching time
    ranges requires cache server to do recombination ... so have
    knowledge about the various media container formats</p>

    <p class='phone'><cite>yves:</cite> implementation hard or not,
    if we no it can be done, than there is no problem</p>

    <p class='phone'><cite>Jack:</cite> caching based on byte
    offsets will work on 99% of the cases</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; Yves: when the
    implementation is done ... it is done! We know it can be done
    ... implementation difficulty should not influence the
    design</p>

    <p class='phone'><cite>jack:</cite> it would work with time
    ranges, but I see no advantages</p>

    <p class='phone'><cite>Yves:</cite> with time ranges, you can
    directly request the fragment</p>

    <p class='phone'><cite>jack:</cite> I fully agree<br />
    ... I think we should leave this issue open</p>

    <p class='phone'><cite>raphael:</cite> more discussion on the
    mailinglist</p>

    <p class='irc'>&lt;<cite>erik</cite>&gt; +q</p>

    <h3 id="item06">AOB</h3>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; regrets for me next
    week (HTTP meeting)</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; thanks davy for the
    scribing</p>

    <p class='irc'>&lt;<cite>rtroncy</cite>&gt; close ACTION-7</p>
