I’ve got a problem with the CIRC process as described in this picture : http://www.ee.washington.edu/conselec/CE/kuhn/cdaudio2/95x74.gif
With a process too long to explain here (wait for my webpage), I got a real life descrambling example, but there is no sign of the “Delay of one symbol” showed in that picture, just after the C1 encoder, in it. Is it possible that it doesn’t exists ?
EDIT : oops, I assumed it was a “delay of one frame”… What it is meant to be, obviously.
Also, in frames with 5 bad symbols, the fact that some of the bad symbols are parity bytes doesn’t seem to prevent the correction of the other audio symbols, that are less than 5 in this case, but in a frame suffering all the same a total of 5 bad symbols.
For the time being, I’m trying to match theory and practice. Do you think the two pieces of theory above can be correct ?
