Yes SP/DIF supports parity, but if the parity is wrong, there are few
alternatives but to mute or conceal the erroneous data.

Matt is correct as far as SP/DIf goes - if an error is detected the only
alternative would be to try to conceal the error as is done with CDs,
since
SP/DIF and AES-3 have no protocol and lack a bi-directional connection for
retries.

One major difference between ripping a CD on a computer, and playing it on
a
CD player, is that most ripping software supports retries.

When digital audio data is encapsulated in other protocols, such as the
protocols between a computer and its disk drives, then the protocol
encapsulating the transfer can and often does support retries.

While this is true, you're likely to need retries reading data from the
media (i.e. CD). Error detection and correction are done in the CD player.
That's why you have players running the CD's at a higher speed than 1X, so
the data can be read many times to support error detection and correction.

By the time the digital data leaves the CD player through a digital coax or
optical digital connection, the likelihood that you're going to need error
detection and correction is very small. Your digital connection between the
player and the receiver will either work, or it won't.
