The simplest way to correct SDI jitter is to insert a digital time-base corrector into your signal path. This instrument will add a buffer into the signal path that allows it to correct for variances in the rate at which it receives data (jitter). The only disadvantage to adding a time-base corrector is that it will add a small amount of delay to your signal. More advanced and preferable methods for correcting jitter generally involve tracing down the source of the jitter and replacing or repairing those portions of your signal path.
