1. A method of transmitting an electronic media key, the method comprising:
- indicating, on a first device, initiation of transmission of an electronic media key to the first device from a second device, the electronic media key comprising a data identifier and a decryption key, wherein the data identifier is used to locate and access encrypted media data associated with the electronic media key, the decryption key usable for decrypting the encrypted media data, wherein the data identifier points to a location where the encrypted media data is stored, and wherein the location is remote from the electronic media key and the first device;
receiving, by the first device, the electronic media key from the second device; and
upon the first device receiving the electronic media key from the second device, printing a physical media key including machine readable information, the machine readable information including the data identifier and the decryption key included in the electronic media key.

16. A method comprising:
-
indicating, using a first indicator on a first device, initiation of transmission of an electronic media key to the first device from a second device, the electronic media key comprising a data identifier and a decryption key, the data identifier used to locate and access encrypted media data associated with the electronic media key, the decryption key usable for decrypting the encrypted media data, wherein the data identifier points to a location where the encrypted media data is stored, and wherein the location is remote from the electronic media key and the first device; upon the first device receiving the electronic media key from the second device; accessing, by the first device, the remotely stored encrypted media data using the data identifier included in the electronic media key; decrypting, by the first device, the accessed encrypted media data using the decryption key included in the electronic media key to produce decrypted media data; and outputting, by the first device, the decrypted media data. - View Dependent Claims (17, 18, 19, 20)
