7. The gateway apparatus of claim 6 , wherein said re-encryption of said content comprises encryption according to one or more digital rights management (DRM) techniques.

8. A digital video recorder (DVR) apparatus configured to enable synchronization of content to one or more portable media devices (PMDs), said DVR comprising:

at least one first interface configured to communicate with one or more entities of a content delivery network;

a second interface configured to communicate with said one or more PMDs;

a storage entity configured to store a plurality of encrypted content received from a content server of said content delivery network; and

a processor apparatus configured to:

run at least a digital rights management (DRM) client application thereon, said DRM client application configured to request and receive a DRM license from a DRM server of said content delivery network, said request comprising a hash value anonymously identifying said DVR, said DRM license being created based at least in part on a determination that said DVR is entitled to receive access thereto, said determination based at least in part on communication of said DRM server with one or more entitlement entities of said content delivery network and comprising use of said hash value; and

run at least one second computer application, said at least one second computer application comprising a plurality of instructions which are configured to, when executed:

receive a request for first content from said one or more PMDs;

identify said first content among said plurality of encrypted content stored at said storage entity;

decrypt said first content via at least information contained in said DRM license;

determine whether said identified first content comprises a format compatible with said one or more PMDs;

when it is determined that said format is not compatible, transcode said first content to a format compatible with said one or more PMDs;

re-encrypt said first content according to DRM standards; and

provide said first content and said DRM license to said one or more PMDs.

9. The DVR of claim 8 , wherein said plurality of encrypted content stored at said storage entity comprises content encrypted according to PowerKey content access standards.

10. The DVR of claim 8 , wherein said at least one second computer application is further configured to, when it is determined that said format is compatible, provide said content to said one or more PMDs in said compatible format and without transcoding said content.

11. The DVR of claim 8 , wherein playback of said content at said one or more PMDs comprises a transmitting a request using an identical DRM client application for said DRM license.

12. A method of synchronizing content from a first premises device to at least one portable device in communication therewith, said method comprising:

storing at least first content at a storage entity of said first premises device, said at least first content being stored in a first encrypted format;

requesting and storing a license via a client application running on said first premises device, said license received from a server in direct or indirect communication with said first premises device, said license based at least in part on communication between the server and a database to determine that said first premises device is associated with an authenticated user, said determination based at least in part on a hash value provided to said server that anonymously identifies said user, said authentication configured to authorize said first premises device to access said first content;

receiving a request at said first premises device for said first content stored at said storage entity, said request originated from said at least one portable device;

in response to said received request:

(i) using at least information contained in said license to decrypt said first content from said first encrypted format and re-encrypt said first content to a second encrypted format;

(ii) transcoding said first content from a first encoding format not compatible with said portable device to a second encoding format compatible with said portable device; and

(iii) providing said transcoded and re-encrypted first content to said portable device, said portable device also configured to run said client application configured to access said license from said server to enable said decryption of said re-encrypted first content.

13. The method of claim 12 , wherein said client process of said portable device and said client application of said first premises device comprise client processes with common encryption/decryption capabilities.

14. A method of providing content to a client device in a premises network, said premises network in data communication with a managed content delivery network, said method comprising:

receiving said content at an intermediary entity of said premises network from a content server of said managed content delivery network, said content being encrypted according to a first access control standard;

in response to a determination that said intermediary entity is entitled to access said content, receiving a rights package from a DRM server of said managed content delivery network;

receiving a request for said content originated from said client device;

authenticating a user of said client device as a subscriber of said managed content delivery network;

identifying a current subscription or service level of said user;

determining one or more rights of said user based at least on said current subscription or service level; and

performing via at least said intermediary entity, in response to said request and based at least on said authenticating and said determined one or more rights:

decryption of said content via at least information received in said rights package;

transcoding of said content from a first encoding format to a second encoding format;

re-encryption of said content according to a second access control standard; and

provision of said content and said rights package for delivery to said client device;

wherein said determination comprises use of a cryptographic hash by said DRM server and a communication with at least one database, said cryptographic hash anonymously identifying said intermediary entity.

15. The method of claim 14 , wherein said rights package comprises a digital rights management (DRM) license; and wherein said request is made via a DRM client running on said intermediary entity which is configured to have identical protected content access functionality to a DRM client running on said client device.

16. The method of claim 14 , wherein said second encoding format comprises a format compatible with capabilities of both said client device and at least one other client device in said premises network.

17. The method of claim 16 , wherein said first encoding format comprises a Moving Pictures Experts Group (MPEG)-2 format, and said second encoding format comprises an MPEG-4 or H.264 format.

18. The method of claim 12 , wherein said first encrypted format comprises encryption according to PowerKey content access standards.

19. The method of claim 12 , wherein said second encrypted format comprises encryption according to one or more digital rights management (DRM) techniques.

20. The method of claim 12 , wherein said first encoding format comprises an Moving Pictures Experts Group (MPEG)-2 format, and said second encoding format comprises an MPEG-4 format.

21. The method of claim 14 , wherein said first access control standard comprises a PowerKey content access standard.

22. The method of claim 14 , wherein said first encoding format comprises a Moving Pictures Experts Group (MPEG)-2 format, and said second encoding format comprises an MPEG-4 or H.264 format.
