I know absolutely nothing about the digital formats, but I do know that
there are at least two different types of digital output on CD players.
One type is the random access digital signals that you would need to make
the CD player into a CD rom reader.  There was another format a few years
ago that never really got off of the ground.  It was supposed to be for
video and text to put liner notes, photos, and lyrics directly onto a
CD.  You would connect the decoded output to your TV or Video monitor,
then watch the stuff as the CD played.  I recall seeing several CD players
that offered this (including Sony machines), but only a hand full of CDs
ever encoded any information in this format.  The plug for this was similar
to a DIN connector, only smaller.
