8. A transfer method for transferring content between a storage apparatus and a playback apparatus, comprising:
-
storing a plurality of pieces of content data in a storage medium; editing program lists in which content identifiers of the pieces of content data stored in the storage medium are registered, and associating each of the plurality of program lists with corresponding apparatus identification information uniquely identifying the playback apparatus; performing transfer control to cause apparatus identification information uniquely identifying a playback apparatus to be received, extract a program list with which apparatus identification information that matches the received apparatus identification information is associated, and cause content data that is not stored in the other storage medium within content data corresponding to a content identifier included in the extracted program list to be transferred from the storage medium to the playback apparatus, the performing compares the program list with a list configured using a content identifier of the content data stored in the other storage medium, and causes content data corresponding to a content identifier that is not included in the program list and that is included in the list to be deleted from the other storage medium; and storing the transferred content data to another storage medium. - View Dependent Claims (9, 10, 11, 12, 13, 14, 18)
