Just a thought ...
Many breakthroughs in compression such as ... (I'll leave you to
fill in an appropriate acronym or trade name) neglect to mention
that the effort required to encode usually increases greatly in
order that the highest compression ratios are achieved. This means
that they are usually not applicable to live video, although can
sometimes work well for 'taped' video, where a thundering great
cluster can munge away for days working wonders on half an hour
Also, if the originator (and now presumably MWC) want to keep the
system under lock and key, that probably means that the AG community
isn't very interested, as we're after public domain, multi-platform
OK, it was two thoughts!
