发明名称 METHOD AND SYSTEM FOR MANAGING ACCESS TO MEDIA FILES
摘要 Access to selected content in different file formats can be managed by conducting, in a single purchase transaction, a user purchase of access rights that allow a user to acquire multiple copies of the same selected content in media files having different file formats. An authorization signal is communicated to a content provider or multiple content providers who did not conduct the purchase transaction. The authorization signal contains information that allows the content provider or the multiple content providers to authorize the user to acquire multiple copies of the same selected content in different file formats without requiring the user to conduct multiple transactions. Each copy of the selected content acquired from a content provider is in a media file having a different file format.
