Re: [AVT] Vorbis RTP issues list for Vienna



I may be incorrect here, but from my discussions with Phil earlier
in the year, the codebook issue has these requirements:

 -- May change every few minutes (say, once per song when used for
    Internet radio apps).




IMHO, this is a flaw in the "Vorbis" architecture.  It would be much better 
to have a fixed, predefined set of codebooks that all receivers would know 
in advance.  Then you'd need to send only a 'codebook id', which should be 
small enough to include in the Vorbis RTP payload format header.



Having to send a complete codebook for each song partially defeats the 
purpose of audio compression.



The Vorbis designers should just figure out a complete set of codebooks 
that are likely to be useful, and settle on those.
