Open for Revision: E1.31, a.k.a. sACN

E1.31, Entertainment Technology – Lightweight streaming protocol for transport of DMX512 using ACN, describes a mechanism to transfer DMX512 A packets over a TCP/IP network using a subset of the ACN protocol suite. It covers data format, data protocol, data addressing, and network management. It also outlines a synchronization method to help ensure that multiple sinks can process this data concurrently when supervised by the same controller. E1.31 was last revised in 2016 to incorporate DMX512A universe synchronisation. The Control Protocols Working Group is now opening the document for revision limited to the incorporation of IPv6 and to correct errors. Input on additional features is not being sought at this time.
