 ====== NetMDLinux ======
+===== Software =====
 There are several orphanend open-source projects aiming to support NetMD Walkman devices under Linux, namely:
-libnetmd: A library to connect to NetMD Walkman - [[http://libnetmd.sourceforge.net/]] and [[http://www.unmaintained-free-software.org/wiki/Libnetmd]]
+  * libnetmd: A library to connect to NetMD Walkman - [[http://libnetmd.sourceforge.net/]] and [[http://www.unmaintained-free-software.org/wiki/Libnetmd]]
+  * Patch for libnetmd to add support for MZ-RH1 and -RH10, also minor casting fixes: [[http://users.physik.fu-berlin.de/~glaubitz/linux-minidisc/0001-cast-fixes-MZ-NH600-MZ-RH1-MZ-RH10-support-adde.patch]]
+  * gnetmd: A GUI for libnetmd - [[http://www.pdr.cx/projects/gnetmd/main]]/
+  * Xmd: NetMD software for Mac OS X - [[http://www.sorted.org/Xmd/]]
+  * WinNMD: non-free Windows software - [[http://winnmd.net/]]
+  * FreeMD: how the NetMD protocol works, and a shell to set track titles etc.

+===== Official Specs and Patents =====
-gnetmd: A GUI for libnetmd - [[http://www.pdr.cx/projects/gnetmd/main]]/
+The NetMD protocol is based on the AV/C Digital Interface Command Set, an 1394 TA specification:
-Xmd: NetMD software for Mac OS X - [[http://www.sorted.org/Xmd/]]
-WinNMD: non-free Windows software - [[http://winnmd.net/]]
-FreeMD: how the NetMD protocol works, and a shell to set track titles etc.

-  * [[http://software.marcus-brinkmann.org/projects/show/freemd]]
-  * bzr branch http://bzr.marcus-brinkmann.org/freemd/trunk/ freemd
-The NetMD protocol is based on the AV/C Digital Interface Command Set, an 1394 TA specification:
   * 2004006 AV/C Digital Interface Command Set General Specification Version 4.2
   * 2004005 AV/C Tape Recorder/Player Subunit Specification 2.4
   * 2002013 AV/C Descriptor Mechanism 1.2
-  * 2002002 AV/C Disc Subunit - Generic Recordable Video Disc Media Type Specification 1.0
+  * <del>2002002 AV/C Disc Subunit - Generic Recordable Video Disc Media Type Specification 1.0</del> For MD, 1998014 is relevant instead of this document.

-Loading files on the MiniDisc Player, in particular the role of the EKB, is described in the [[http://www.marcus-brinkmann.de/files/pat7228568.pdf|US Patent 7228568]]
+Here is an older document by the TradeAssociation:
-(retrieved via [[http://www.pat2pdf.org/]]), which contains some hilariously bad cryptography (and is in any other way utterly trivial).  This answers many, but not all, questions about the file transfer logs.  YAP: [[http://www.marcus-brinkmann.de/files/pat7362870.pdf|US Patent 7362870]].  Also noteworthy may be US Patent 20050246286, which seems to document how OpenJukeBox manages licenses.

+  * {{:avc_general_30.pdf|1998003 AV/C Digital Interface Command Set General Specification Version 3.0}}
+  * The Sony patent [[https://wiki.physik.fu-berlin.de/linux-minidisc/lib/exe/fetch.php?media=us7437770.pdf |US7437770]] describes in details the entire communication between a NetMD device and a PC starting with the exclusive login and retrieving of the track titles. The data exchange commands are shown in the form control/response frames (Figures 33-49). It's quite easy to understand the stuff, especially by working in conjuction with the AV/C documents mentioned above.

+===== Other Information =====
-The EKB format is mostly revealed now.  There is now a [[http://software.marcus-brinkmann.org/repositories/changes/freemd/tools/dump-ekb.py|Dump EKB]] tool that can be used to display EKB files.  Here is an example output (the unique keys have been blacked out):
