This provides an informative overview, even if an advertisement for Q-Lan: http://www.qscaudio.com/products/network/QSys/Q-LAN_WhitePaper_2009-10.pdf (authored by the patent-holder on CobraNet: http://bit.ly/9TOyJt (*)) >AVB™ is a layer-2 network solution.

These xmos units look quite promising for $149.00: https://www.xmos.com/products/development-kits/xc-2-ethernet-kit And (OT) make it possible to cost-efficiently recreate great ideas originating as burning man projects: http://petrinis.se/blog/swarm-light/ http://www.youtube.com/watch?v=YqexlHt1Mw0&feature=related (TODO: large area sonic-holography network using ethernet and hundreds of these xmos units and consumer "digital tv" i2s-to-class-D amplifier units and "tv-size" loudspeakrs, all solar powered and outdoor-situated :-) ) Regarding audio over ethernet -- see also: http://en.wikipedia.org/wiki/Audio_over_Ethernet http://en.wikipedia.org/wiki/MADI http://en.wikipedia.org/wiki/EtherSound http://en.wikipedia.org/wiki/AES47 Niels http://nielsmayer.com (*): http://bit.ly/9TOyJt == http://books.google.com/books?id=y0d9VA0lkogC&pg=PA1346&lpg=PA1346&dq=kevin+gross+QSC&source=bl&ots=APtb9Fe6mM&sig=jQrWKVBJNufz_GthfwFgnNDuy94&hl=en&ei=o0s7TKjaNZHWtQODxrjaCg&sa=X&oi=book_result&ct=result&resnum=5&ved=0CCIQ6AEwBA#v=onepage&q=kevin%20gross%20QSC&f=false _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
