A provider network device communicates with the memory and wirelessly communicates with a requester network device that requests a copy of the content. The provider network device determines a local/remote status of the requester network device, transmits a key request to the requester network device when the requester network device has a local status, receives a key from the requester network device, encrypts the content with the key and transmits the encrypted content to the requester network device.
CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation-in-part of U.S. patent application Ser. No. 11/085,761 filed on Mar. 21, 2005. This application is related to U.S. patent application Ser. No. 11/039,288 filed on Jan. 19, 2005. The disclosures of the above applications are incorporated herein by reference in their entirety.
FIELD OF THE INVENTION The present invention relates to networks, and more particularly to network systems that allow secure distribution of protected content.
BACKGROUND OF THE INVENTION Consumers often purchase video content on digital versatile discs (DVDs). A DVD player may be used to output the video content to a television (TV) or other video monitor. Some DVD players may include a carousel for allowing selection and play of one of a plurality of DVDs. In some situations, a consumer may want to view the DVD content on a first TV in one room of the consumer's home when the DVD player is located and connected to a second TV in another room. As a result, the DVD player needs to be disconnected from the second TV, moved to the room with the first TV and reconnected to the first TV. Alternately, if the consumer has a second DVD player, the consumer moves the DVD to the other player.
SUMMARY OF THE INVENTION A system for distributing content in a network comprises memory that stores content. A provider network device communicates with the memory and wirelessly communicates with a requester network device that requests a copy of the content. The provider network device determines a local/remote status of the requester network device, transmits a key request to the requester network device when the requester network device has a local status, receives a key from the requester network device, encrypts the content with the key and transmits the encrypted content to the requester network device.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. As used herein, the term module or device refers to an application specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) and memory that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable components that provide the described functionality. For purposes of clarity, the same reference numbers will be used in the drawings to identify similar elements.
The network device 30-2 communicates with the router 28 and with a DVD player or a combined DVD/HDD player 44 (both referred to hereinafter as �DVD player 44�) such as the one shown and described in U.S. patent application Ser. No. 11/039,288, filed Jan. 19, 2005, which is hereby incorporated by reference in its entirety. The DVD player 44, in turn, may communicate with a television or monitor 46, which may be connected to the medium 16 or to a set top box 50. The service provider 18 provides broadband access to the DCS 22, video content and/or other services. One or more other servers 54-1 and 54-2, (collectively servers 54) provide an interface for network devices 60, computers 62, personal digital assistants (PDAs), etc. to the DCS 22.
