Transferring a data object between devices
摘要:
A playable copy of the digital content object is stored at a first device. A data object associated with the digital content object is sent to a second device. The playable copy of the digital content object is disabled at the first device, such that only an authorized, playable copy of the digital content object is operable to be stored on the first and second device at any given time before, during and after sending the data object.
