Meeting of SC-06-02, 2003-10

Report of SC-06-02 Working Group on Audio Applications Using the High Performance Serial Bus (IEEE 1394) of the SC-06 Subcommittee on Network and File Transfer of Audio meeting, held in conjunction with the AES 115th Convention, New York, NY., US., 2003-10-10

The meeting was convened by chair J. Strawn.

The agenda and the report of previous meeting were approved as written.


AES-X075: IEC Liaison for IEC-PAS 61883-6 Consumer audio/video equipment � Digital interface � Part 6: Audio and music data transmission protocol
J. Fujimori is the new liaison, following the retirement of Y. Osakabe. The final draft international standard (FDIS) for updates to IEC 61883-6 was circulated for discussion.

AES-X127 : Liaison with IEEE 1394.1
S. Harris reported that P. Johansen, who was writing the 1394.1 standard, has recently gotten new funding and will continue. There is no date yet for the availability of the next draft.

AES-X137: Liaison with 1394 Trade Association (1394 TA)
Fujimori reported as follows:

The 1394TA had its second quarter meeting at Oxford Semiconductor in 2003-07. The next meeting is set for October 20-23, 2003, South San Francisco, California, USA.

The A/V Working Group is looking at the following topics:

  1. Blu-ray DVD recording.
  2. Japanese terrestrial DTV.
  3. A point-to-point test network.
  4. AVC Camera storage subunit 2.1.
  5. BRC review of 1394 implementation tests.
  6. S800 Base-T, now known as IEEE-1394c.
  7. Pin assignments on UTP5 cable. The proposal from Digital Home Technology is to use pins 4 and 5 for 48V, and 3 and 6 for ground. B. Moses will get more information on this.
The A/V working group voted on AVC printer subunit 2.0

M. Mora of Apple asked if the Trade Association plans to publish audio guidelines similar to video guidelines. Fujimori answered that the DVD Forum and other organizations are expected to do that within their application space.

Open Projects

There was no discussion.

AES-X126 : Profile for professional audio over 1394
Task group SC-06-02-G met before the SC-06-02 meeting. SC-06-02-G promoted the proposal of Fujimori for General Data up to SC-06-02.

K. Ruling of the Entertainment Services & Technology Association (ESTA) presented their draft standard BSR E1.17, commonly known as "ACN", a network control protocol suite.

AES-X132: Synchronisation of audio over IEEE 1394
We continue to await the completion of 1394.1, we then anticipate a report from T. Thaler.

New Projects

Strawn will submit a project initiation form for General Data based on IEC 61883-6. A rewriting group will meet during the convention. Strawn will post the revised draft to the SC-06-02 document site.

New Business

Bob Moses gave an update on 1394b and 1394c. Steven Harris gave a tutorial on 1394.1

The next meeting is scheduled to be held in conjunction with AES 116th convention in Berlin, 2004-05.
