AES11

<h2 id="related-developments">Related developments</h2>
<p>AES11 Annex D (in the November 2005 or later printing or version) shows an example method to provide <a href="/facts/Isochronous/4aX8RPCl">isochronous</a> timing relationships for distributed AES3 structures over asynchronous networks such as <a href="/facts/AES47/Vw7GV8Ak">AES47</a> where reference signals may be locked to common timing sources such as <a href="/facts/GPS/DKVLnzF3">GPS</a>.
</p><p>In addition, the <a href="/facts/Audio_Engineering_Society/SgW7IJ9f">Audio Engineering Society</a> has now published a related standard called <a href="/facts/AES53/uIMknpCB">AES53</a>, that specifies how the timing markers already specified in <a href="/facts/AES47/Vw7GV8Ak">AES47</a> 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.
</p><p>The media profile defined in annex A of <a href="/facts/AES67/uXSJhUhj">AES67</a> provides a means of using AES11 synchronization via the <a href="/facts/Precision_Time_Protocol/N5u5HVqx">Precision Time Protocol</a>.
