BBC’s DIRAC codecs

Matt web and tom coats seem to be doing a lot of interesting things in
bbc radio and
music
. But I heard about bbc's open source
sourceforge project called DIRAC through this weeks NTK.net. Its basically a experimental video
codec like ogg theora. It supports resolutions
from quarter cif to 1080 hdtv progressive or interlaced.
Oddly it also uses wavelets and motion compensation as well the patent
tricky area of Arithmetic coding.
Anyway i'm going to try it out and if its good, i'm thinking we could
use it for the copyright vs community
lectures
. But I douht its ready for
such use, saying that we could get some support from the bbc if I ask
really nicely? maybe? Worth a email I would say, wouldn't you?

I am hoping to push some of this type of innovation into the world
service. Theres already an opportunity to do some work on blogging for
43 different languages. Hence why i'm watching blojsom's
Internationalization
. Thinking of bringing some of the work with HP's
semantic blogger to the world service. I mean blojsom is that flexible.
Only problem is were using mainly perl and cgi on the backend with
server side includes at the final stage. Don’t think this much of a
secret because everyone can see bbc.co.uk uses *.shtml. Anyway blojsom
with a bit of xsl 1.1 or even 1.0 could create static pages if needed.
More about xsl 1.1 soon I think.
