| + | * 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. | ||
| + | * 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]] (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. | ||
