1. An interconnect for connecting a source device to a destination device to facilitate delivery of media content that is associated with a rights management restriction, comprising:
- a first communication interface for communicatively coupling the interconnect to a communication interface of the source device;
a source media interface for a direct wired connection to a non-compliant rights management media interface of the source device;
a destination media interface for a direct wired connection from the interconnect to a media interface of the destination device; and
a control system associated with the first communication interface, the source media interface, and the destination media interface and adapted to;
receive from the source device via the, first communication interface first information indicating first media content to be delivered from the source device to the destination device is associated with the rights management restriction;
in response to receiving the first information from the source device indicating that the first media content to be delivered from the source device to the destination device is associated with the rights management restriction, determine whether the media interface of the destination device is compliant with the rights management restriction associated with the first media content; and
if the media interface of the destination device is determined to be compliant with the rights management restriction associated with the first media content;
send to the source device via the first communication interface second information indicating that the media interface of the destination device is compliant with the rights management restriction associated with the first media content; and
in response to sending the second information to the source device;
receive from the source device via the source media interface encrypted media content, which is the first media content encrypted based on compliance encryption information;
decrypt the encrypted media content to provide unencrypted media content;
encrypt the unencrypted media content based on rights management encryption information associated with the media interface of the destination device to provide re-encrypted media content; and
deliver the re-encrypted media content to the media interface of the destination device via the destination media interface.

11. A source device comprising:
-
a first hardware communication interface for connecting to a communication interface of an interconnect that couples the source device to a destination device; a non-compliant rights management media interface for a direct wired connection to a media interface of the interconnect; and a control system associated with the first communication interface and the non-compliant rights management media interface and adapted to; determine whether media content to be delivered to the destination device is associated with a rights management restriction; send via the first communication interface a first message indicating whether the media content is associated with a rights management restriction; receive via the first communication interface a second message indicating whether the destination device has a compliant rights management media interface; when the media content is associated with the rights management restriction and the destination device has a compliant rights management media interface, encrypt the media content based on compliance encryption information to generate encrypted media content; and deliver the encrypted media content via the non-compliant rights management media interface to the interconnect. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for operating an interconnect that connects a source device to a destination device to facilitate delivery of media content that is associated with a rights management restriction, comprising:
-
receiving via a first communication interface that communicatively couples the interconnect to a communication interface of the source device first information indicating first media content to be delivered from the source device to the destination device is associated with the rights management restriction; in response to receiving the first information from the source device indicating that the first media content to be delivered from the source device to the destination device is associated with the rights management restriction, determining whether a media interface of the destination device is compliant with the rights management restriction associated with the first media content; and if the media interface of the destination device is determined to be compliant with the rights management restriction associated with the first media content; sending to the source device via the first communication interface second information indicating that the media interface of the destination device is compliant with the rights management restriction associated with the first media content; and in response to sending the second information to the source device; receiving via a source media interface that provides a direct wired connection from the interconnect to a non-compliant rights management media interface of the source device encrypted media content, which is the first media content encrypted based on compliance encryption information; decrypting the encrypted media content to provide unencrypted media content; encrypting the unencrypted media content based on rights management encryption information associated with a compliant rights management media interface of the destination device to provide re-encrypted media content; and delivering the re-encrypted media content to the compliant rights management media interface of the destination device via a destination media interface of the interconnect that provides a direct wired connection from the interconnect to the compliant rights management media interface of the destination device.

24. A method of operating a source device to provide media content to a destination device via an interconnect comprising:
-
determining whether the media content to be delivered to the destination device is associated with a rights management restriction; sending via a first communication interface that communicatively couples the source device to a communication interface of the interconnect a message indicating whether the media content is associated with the rights management restriction; receiving from the interconnect via the first communication interface a second message indicating whether the destination device has a compliant rights management media interface; and when the media content is associated with the rights management restriction and the destination device has a compliant rights management media interface, effecting encryption of the media content based on compliance encryption information to generate encrypted media content for delivery via a non-compliant rights management interface of the source device to the interconnect. - View Dependent Claims (25)
