I would like to capture the digital output from my C.D. player.  There is
a jack on the back which provides access to this, but I don't know the
format of the bitstream.  I know that digital audio is 16 bit linear PCM
at a sampling rate of 44.1(?) kHz but what I don't know is what kind of
framing and timing information they stick in the bitstream.  Is there
any kind of industry standard for these 'digital outputs' or am I out
of luck?

It would be nice to also grab the subcode data also.  I know of at least
one released C.D. that has some type of graphics in the subcode that can
be displayed on a monitor or T.V. while the music is playing (with some
probably proprietary adapter).

Analog Devices has a 'Industry standard pinout' DAC in a 16 pin package
(AD1856) which has three digital inputs - CLK, LE, DATA.  I take it that
the serial bitstream coming into this device is standardized - probably
just the linear PCM audio signal.  They also make an 18 bit version.

Thanks,
