AES11 Annex D (in the November 2005 or later printing or version) shows an example method to provide
isochronous timing relationships for distributed AES3 structures over asynchronous networks such as
AES47 where reference signals may be locked to common timing sources such as
GPS. In addition, the
Audio Engineering Society has now published a related standard called
AES53, that specifies how the timing markers already specified in
AES47 may be used to associate an absolute time-stamp with individual audio samples. This may be closely associated with AES11 and used to provide a way of aligning streams from disparate sources, including synchronizing audio to video in networked structures. The media profile defined in annex A of
AES67 provides a means of using AES11 synchronization via the
Precision Time Protocol. ==References==
