Z2-1 An mLAN Connection Management Server for Web-Based, Multi-User, Audio Device Patching— Jun-ichi Fujimori, Yamaha Corporation, Hamamatsu Japan; Richard Foss, Brad Klinkradt, Shaun Bangay, Rhodes University, Grahamstown, South Africa
A connection management server has been developed that enables connections to be made between mLAN-compatible audio devices, via a client web browser on any web-enabled device, such as a laptop or PDA. The connections can also be made across IEEE 1394 bridges and will allow for the transport of audio and music data between mLAN devices on the same or separate IEEE 1394 buses. Multiple users will be able to make and break connections via the server.

Z2-2 The Audio File Format for Digital Distribution—Shigeru Aoki, TokyoFM Broadcasting, Tokyo, Japan; Hirokazu Nakashima, TBS R&C, Tokyo, Japan
The Japan FM Network, 38 affiliate FM broadcasting companies all over Japan, installed the digital audio program file distribution network system to abolish conventional analog distribution. This system reduces the distribution cost and duration compared with the traditional technique of broadcasting relay where one station records another station’s program off-air for later use. This paper also describes the format of digital audio file for current distribution and presents solutions to some existing problems.

Z2-3 Design Method of Digital Audio Network System for Auditoriums—Masahiro Ikeda, Shinjiro Yamashita, Shinji Kishinaga, Fukushi Kawakami, Yamaha Corporation, Hamamatsu, Japan
In terms of the sound systems installed in auditoriums, it is difficult to design comprehensive networking systems because of limitations in available channels, latency, and cost. However, with rapid progress of networking devices, digital audio networks will become more valuable in the field of performing arts. This paper discusses required functions of network audio systems for auditoriums from the system-design viewpoint using a 2300-seat multipurpose hall as an example. Comparing the system against networking technologies that are suggested today, the paper will also discuss the feasibility of the example and point out problems in realizing such systems.
