< communications > /i:-sok'rn-*s/ A form of data transmission that guarantees to provide a certain minimum data rate , as required for time-dependent data such as video or audio .
Isochronous transmission transmits asynchronous data over a synchronous data link so that individual characters are only separated by a whole number of bit-length intervals. This is in contrast to asynchronous transmission, in which the characters may be separated by arbitrary intervals, and with synchronous transmission [which does what?].
Asynchronous Transfer Mode and High Performance Serial Bus can provide isochronous service.
Compare: plesiochronous .
