Accessing rights-managed content from constrained connectivity devices

A computer program product, comprising a non-transitory computer-readable medium having computer readable program code embodied therein, the computer readable program code comprising instructions that, when executed by one or more processors of an interface server, cause the interface server to perform a method comprising:

• receiving, by the interface server, a plurality of content units, the plurality of content units comprising unprotected content and at least one protected content unit from a content server, the plurality of content units being designated for the wireless device, the content server being external to the interface server;
• determining, by the interface server, that the at least one protected content unit is protected by querying a digital rights management (DRM) server as to whether the received plurality of content units are registered, the DRM server being external to the interface server;
• requesting, by the interface server, access information for the at least one content unit from the DRM server in response to the determining that the at least one protected content unit is protected;
• receiving, by the interface server, the requested access information;
• and
• transmitting, by the interface server, the at least one protected content unit and the access information for the at least one content unit to the wireless device without the wireless device requesting access to the at least one protected content unit, the transmitting the access information being in response to the determining that the at least one protected content unit is protected.

An interface server for implementing a digital rights management (“DRM”) system on a wireless device connected to a wireless network, the interface server comprising:

• one or more processors;
• and
• a non-transitory computer readable medium storing a plurality of instructions that, when executed by the one or more processors, cause the one or more processors to perform a method comprising:
• receiving a plurality of content units, the plurality of content units comprising unprotected content and at least one protected content unit from a content server, the plurality of content units being designated for the wireless device, the content server being external to the interface server;
• determining that the at least one protected content unit is protected by querying a digital rights management (DRM) server as to whether the received plurality of content units are registered, the DRM server being external to the interface server;
• requesting access information for the at least one content unit from the DRM server in response to the determining that the at least one protected content unit is protected;
• receiving the requested access information;
• and
• transmitting the at least one protected content unit and the access information for the at least one content unit to the wireless device without the wireless device requesting access to the at least one protected content unit, the transmitting the access information being in response to the determining that the at least one protected content unit is protected.
