RE: Thanks, but could you please elaborate on...

The same bits can be conveyed by slightly different waveforms due to noise and timing issues associated with the transmitter at the transport, the digital cable, or the digital receiver in the DAC. In an ideal world, the digital receiver in the DAC would correctly interpret the bits and would eliminate all of the noise and timing issues. In the actual world, this does not happen and some of the variations make it to the analog output of the DAC.

Here are two strings of bits that are the same, but are physically different on the screen:

0 1 0 1 0 01 0 1 1 1 01
0 101 0 0 1 0 1 1 1 0 1
