Claim:
A content management method comprising: receiving a first instantiation of first digital content at a device, wherein the first instantiation is encoded in a first format; determining an identity of the received first digital content; storing the identity of the received first digital content on the device; the device determining that a user has a right to play the first digital content by accessing a rights management logic; receiving a second instantiation of second digital content at the device, wherein the second digital content is encoded in a second format that is different from the first format; determining an identity of the received second digital content; the device determining whether the user has a right to play the received second digital content without accessing the rights management logic by comparing the determined identity of the received first digital content with the determined identity of the received second digital content to make a determination of whether the second digital content is the same as the first digital content, wherein comparing the determined identity of the received first digital content with the determined identity of the received second digital content comprises retrieving the stored identity of the received first digital content on the device and comparing the stored identity of the received first digital content with the determined identity of the received second digital content; and responsive to the determination being that the second digital content is the same as the first digital content, enabling the user to play the second digital content.
