Terminology OpenMG Copyright protection technology that manages the music data from EMD/Audio CD on a personal computer. Application software installed in the computer encrypts the digital music content when recording on the hard disk. This allows the user to enjoy music content on the computer, but prevents unauthorized transmission of contents across a network or elsewhere. SDMI (Secure Digital Music Initiative) A forum constituted of approximately 130 or more companies in the fields of audio records, computers and consumer electronics, for the purpose of developing an integrated method of copyright protection technology that can be used world wide. It is working to create a framework for preventing illegal usage of audio files and to promote legal music distribution services. The copyright protection technology OpenMG, used in the OpenMG Jukebox, is based upon the SDMI standard. Check in/Check out Check out is to transfer an audio data managed on a personal comuputer by an OpenMG-compliant software to a portable player (Music Clip Player, etc.). Returning the checked out audio data back to that comuputer is to check out. (You cannot move a checked out audio data to another comuputer.) You can also check out a data, check it back in, and then check it out again. According to the basic rule of the SMDI, up to four copies of an audio file can be created by copying it once, except for the audio data to which a special condition for usage is set. Thus, while one copy is saved in the computer, the other three can be checked out to the portable players. (continued) 31
