Ten EPIs to Facilitate ACN in Public Review
Ten documents that are part of BSR E1.30-200x, Application level equipment interoperability for control of commonly encountered entertainment technology devices using ANSI E1.17, have been posted on the ESTA website at http://www.esta.org/tsp/documents/public_review_docs.php for review through 25 August 2008. The ten new draft documents add to the functionality of ANSI E1.17, ACN, by specifying how to do common tasks in ACN. The ten draft documents are:
BSR E1.30-1-200x, EPI 23, Device Identification Subdevice
EPI 23 specifies a templated device for device identification as typically used for remote hardware and software devices.
BSR E1.30-2-200x, EPI 24, Internet Protocol Properties Subdevice
EPI 24 specifies two template devices, each describing a block of properties used for supplying information on and configuring the Internet Protocol (IP) configuration of a device, using DMP. These devices may typically be used for remote hardware or software devices to allow configuration over the network.
BSR E1.30-3-200x, EPI 25, Time Reference in ACN Systems Using SNTP and NTP
EPI 25 specifies restrictions and guidelines for establishment of a common time reference across components within an ACN system using SNTP (Simple Network Time Protocol) and optionally NTP (Network Time Protocol). This EPI does not define a control synchronization model.
BSR E1.30-4-200x, EPI 26, Device Description Language (DDL) Extensions for DMX512 and E1.31 Devices
EPI 26 defines protocol specific extensions to Device Description Language for describing DMX512-type devices.
BSR E1.30-5-200x, EPI 27, Operation of SDT on Wireless Networks
EPI 27 outlines issues with SDT usage over wireless networks, specifically 802.11g. It proposes changes to EPI 18 constants and speculates on 802.11n.
BSR E1.30-6-200x, EPI 28, Independent Device Location Properties
EPI 28 specifies a non-templated device for Independent Device Location properties as typically used for remote hardware and software devices.
BSR E1.30-7-200x, EPI 29, Allocation of Internet Protocol Version 4 Addresses to ACN Hosts
EPI 29 obsoletes ACN EPI 13 (Allocation of Internet Protocol Version 4 Addresses to ACN Hosts). The principle reason for this revision is to allow assignment of static IP addresses and provide guidance for how to manage systems using these methods.
BSR E1.30-8-200x, EPI 30, Time Code Properties
EPI 30 specifies a non-templated device for Time Code properties as typically used for remote hardware and software devices.
BSR E1.30-9-200x, EPI 31, MIDI System Exclusive Properties
EPI 31 specifies a non-templated device for MIDI System Exclusive properties as typically used for remote hardware and software devices.
BSR E1.30-10-200x, EPI 32, Identification of Draft Device Description Language Modules
EPI 32 specifies how draft DDL modules that may be changed frequently during development shall be marked as experimental.
In addition to being asked to review the documents to see if they offer adequate advice, reviewers are asked to notify ESTA of any protected intellectual property in the draft standards. ESTA does not warrant that its standards contain no protected intellectual property, but it also does not intend to adopt any standard that requires the use of protected intellectual property, unless that property is necessary for technical reasons and can be licensed by anyone without prejudice or preference for a reasonable fee.
