[linux-audio-dev] Re: [Alsa-devel] IEEE 1394

for audio+MIDI, there is no fully-defined standard yet. linux already has a compliant 1394 driver, but you normally need extra protocols on top of this for moving specific kinds of data around. IEEE has defined one (IEC61883-6) for audio+MIDI, based on mLAN, and I believe you can get the specs from them or the AES. However, it doesn't support any connection management, so all endpoints have to be explicitly identified by the user, and everything has to be explicitly delivered. Yamaha submitted their scheme for CM to the 1394 trade association as the "AV/C Music Subunit". its been released but not implemented (even by Yamaha) because Yamaha are changing mLAN again. Basically, to quote from someone who really knows this stuff: "So a streaming driver using a format compatible with mLAN devices is not a problem at this stage - it is possible to direct audio/MIDI to mLAN devices and pick up audio and MIDI, but not in a flexible manner. The connection management architecture first needs to settle." --p ps. just a quick note to point out that whether you know it or not, the email program you are using is sending out copies of your mail in both plain text and HTML formats. increasingly on the net, there are filters being put in place that silently dump HTML-formatted email. some mailing lists will not ever accept such posts. as long as you do this, you are (1) wasting network bandwidth by sending messages that are typically more than twice as long as they could be (2) making it harder for people using traditional email readers to read them (3) risking the chance that people will never see your mail because its filtered before reaching their email inbox.
