Jitter is simply a timing error.
... CEC transports use belt drive systems to reduce error rate, also know as jitter ...Error rate and jitter are two different things. Errors result from inability to read data. That is actually rare - because the data is interleaved and encoded redundantly - and when it does it happen, it is almost always resolved through error correction, which is part of the CD standard.
