<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:13pt'>It is interesting, almost funny (or sad depending on the perspective) how the reaction to a _God Forbid_ IP-free video codec is mirroring the opposition to the Internet audio codec. That opposition proved eventually futile and we have now a CODEC WG.<BR>
I hope the AD’s will have now the same fortitude as was shown when the Internet audio codec WG was formed. <BR>
<BR>
I have taken the liberty to copy the CODEC WG and hope they can participate now in the video codec discussion as well.<BR>
My apology for the double posting.<BR>
<BR>
Thanks, Henry <BR>

<BR>
About the video codec: Are there any arguments on why VP8 would not have IPR issues? It is available as an open source implementation, but that does not mean there are no IPR against it. My understanding is that the IPR situation wrt. VP8 is still unclear and thus risky. The other issue with VP8 is, as far as I know, the lack of a clear spec out of which independent interoperable implementations can be created.<BR>
<BR>
So I don’t at least buy the argument that we should choose VP8 as mandatory to implement video codec because of IPR reasons.<BR>
<BR>
I’m working on a separate review on Harald’s drafts (thanks for putting them together) and will come back to the codec issue there in more detail, but just wanted to respond to Peter’s point here.<BR>
<BR>
Regards,<BR>
Markus <BR>
