TVTechnology.com reports that a brilliant decision in developing the recent audio-over-IP standard, AES67-2013, was basing it on existing protocols.
One of the goals for this “AES standard for audio applications of networks—High-performance streaming audio-over-IP interoperability” was to provide low latency (less than 10 milliseconds) between and among AES67 devices on a network. With that in mind, the developers of this standard chose IEEE 1588. The most recent version is from 2008, and the standard is currently being reviewed for possible revisions.
“IEEE 1588 is used for high-speed synchronization over the network. It was the only obvious choice for establishing a synchronization mechanism” said Greg Shay, a member of the AES task group that developed the standard.
