EIA
Electronic Industries Alliance. A U.S. trade organization that was once responsible for establishing
hardware interface standards. The EIA broke apart into several more specialized standards
development organizations (SDOs) including the CEA and TIA. This break-up resulted in the renaming
of a number of key standards (such as CEA-708 and TIA-232) which has caused industry confusion.
Harmonic is careful to use the current and correct names of relevant standards.
