isochronous

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.
