This is a long shot, but it seems worth asking...

Anyone know the *details* of HDCD flagging/encoding and/or know how to
contact 'cjk32' (C. J. Key, I think) who at Cambridge produced the hdcd.exe
for Windows users? I'd love to do an analysis of this, but that means being
able to understand the system and be able to decode discs using my own
software so I know what it happening.

There is a USA patent I've found, but it only gives a woolly all-covering
description. It lacks the details needed to replicate the process with an
existing HDCD.

Slainte,

Jim
