This is in the contents stored on the PC and the iPod that is a portable device (PD) when song data is newly added to the hard disk (HD) by downloading EMD contents or CD ripping. This is a function for comparing song data, transferring song data that is in the hard disk (HD) of the PC but not in the iPod, and making the song data stored in each other the same. Note that iPod and the synchronization function (auto sync) are described in Non-Patent Document 1 and Non-Patent Document 2.

  By using this function, it is possible to automatically transfer the song data downloaded to the hard disk (HD) of the PC to the iPod. However, this function can be realized only with a large-capacity PD that can transfer all songs in the HD such as iPod. Further, it does not realize a process of selecting and transferring specific music data stored in the hard disk of the PC. In particular, when it is desired to select only data that has undergone download processing at the present time and transfer it to a portable device, the iTunes synchronization function of Apple cannot be used.
