What I do know, albeit not alot (yet i hope), is that Multimedia voice
data, in digital form must be in either PCM (Pulse coded Modulation) or
ADPCM. That former for IFF standards and ADPCM for RTF (Real Time Files)
format.  This, however, is Phillips standard, I do not think there is an
International Standard.  Probably will not be for a long time. For    
compression, We do not compress our data, due to the lack of processor
speed.  Our multimedia platform (Phillips CDI) is meant to be a simple
inexpensive machine for CONSUMERS.  Thats the whole waahoo over multimedia.
So I can't help you there, sorry!
