SC-02-12 meeting, Barcelona, 2005-05
Report of the meeting of the SC-02-12 Working Group on Audio Applications Using the High Performance Serial Bus (IEEE 1394) of the SC-02 Subcommittee on Digital Audio, held at the 118th AES Convention, Barcelona, Spain, 2005-05-27The meeting was convened by Chair J. Strawn.
The agenda and the report of the previous meeting were approved as written.
Development ProjectsAES-X075: IEC Liaison for IEC-PAS 61883-6
J. Fujimori-san gave a report; his slides are on the group document site at x75_fujimori_IEC-050527.ppt. This IEC project group met during AES Barcelona and will report to the IEC TC100 Plenary in 2005-09 in San Jose, CA, USA.
Most importantly for us, the Final Draft International Standard (FDIS) for IEC MT61883-6 Ed.2.0 (Consumer audio/video equipment - Digital interface) will circulate in 1-2 weeks, to be finalized several months thereafter. Fujimori-san wants to starts a maintenance team in the 1394 TA, to result in perhaps an Edition 3.0 to include generic data types (see later).
It is expected that edition 3.0 of IEC 60958-3, "Digital audio interface - Part 3: Consumer applications" will progress to CDV during IEC's Barcelona meeting. The CDV for IEC PT 61937-8 (Interface for non-linear PCM encoded audio bitstreams applying IEC 60958 - Non-linear PCM bitstreams according to the Windows Media Audio Professional) closes on 2005-07-15.
PT 62379 (Common Control Interface for digital audio and video products on asynchronous transfer mode (ATM) networks) is to meet during Barcelona to discuss the committee draft (CD). J. Grant pointed out that this project will expand to networks besides ATM.
AES-X101: Data Type, Properties, and Method Definitions for Audio Device Application Program Interfaces (API).
The Secretariat commits to having the PWD formatted by October.
AES-X126: Profile for professional audio over 1394
SC-02-12-G had met earlier in the same day, and discussed a number of topics. Discussion in the task group continues.
AES-X132: Synchronisation of audio over IEEE 1394
Thomas Thaler of BridgeCo has submitted a source document to SC-02-12-G. The AES Secretariat is working with BridgeCo on the necessary patent declaration.
AES-X137: Liaison with 1394 Trade Association (1394 TA)
Fujimori made a report. The slides are on the document site at x137_fujimori_1394ta_050527.ppt. The 1394 TA continues its quarterly meetings. In particular, Yamaha has proposed extensions to the A/M Protocol 2.1, including the already adopted allocation of FDF = 00110xxx for General Data being discussed in Sc-02-12-G.
