Abstract

An online digital entertainment system comprises a first server operable to receive authenticating data from a digital media player via a global computer network and confirm the authenticating data, and a second server operable to generate unique public and private keys in response thereto, and sending the public key to the digital media player. The system further comprises a third server operable to generate a unique session key for each streaming request received from the digital media player, and sending the session key encrypted by the public key to the digital media player, and a fourth server operable to stream digital media content encrypted by the session key to the digital media player via the global computer network, the digital media player operable to decrypt the digital media content using the session key and display the digital media content on a television.

Claims

1. An online digital entertainment system, comprising:

a first server operable to receive authenticating data from a digital media player via a global computer network and confirm the authenticating data;

a second server operable to generate a unique public key and a unique private key in response to the confirmed authenticating data, and sending the generated public key to the digital media player via the global computer network;

a third server operable to generate a unique session key for each streaming request received from the digital media player, and sending the unique session key encrypted by the generated public key to the digital media player via the global computer network; and

a fourth server operable to stream digital media content encrypted by the session key to the digital media player via the global computer network, the digital media player operable to decrypt the digital media content using the session key and display the digital media content on a television set.

2. The system, as set forth in claim 1, further comprising a user database in communication with the first server operable for storing authenticating data and other data associated with the user.

3. The system, as set forth in claim 1, further comprising a key database in communication with the second server operable for storing the public and private keys associated with a user.

4. The system, as set forth in claim 1, further comprising a content database in communication with the fourth server operable for storing digital media content.

5. The system, as set forth in claim 1, further comprising a billing database operable for storing data associated with digital media content streamed to the digital media player.

6. The system, as set forth in claim 1, further comprising a server cluster including the first, second, third and fourth servers.

7. The system, as set forth in claim 1, wherein the first server is operable to receive a unique identifier associated with a storage media encoded with software executed on the digital media player

8. The system, as set forth in claim 1, wherein the fourth server is operable to encrypt the digital media content in blocks prior to streaming to the digital media player.

9. The system, as set forth in claim 1, further comprising a fifth server operable to select a random checksum application and send to the digital media player, and verify a result of the checksum application sent thereto by the digital media player.

10. The system, as set forth in claim 1, wherein the fourth server is operable to respond negatively to a request from a digital media player to stream digital media content in response to a load level exceeding a predetermined level.

11. The system, as set forth in claim 1, wherein the fourth server is operable to stream digital media content to a digital media player beginning at a mid-point of the digital media content.

12. A method of providing on-demand online delivery of digital media content, comprising:

receiving a unique identifier from a digital media player via a global computer network;

authenticating the received identifier;

storing data associated with a user of the digital media player represented by the unique identifier;

receiving a selection of a digital media file from the user; and

streaming the selected digital media file to the digital media player via the global computer network for and for playing on at least one component of an entertainment system coupled to the digital media player.

13. The method, as set forth in claim 12, further comprising:

generating a set of unique public and private keys and delivering the keys to the digital media player via the global computer network; and

generating a session key, encrypting the session key with the user'"'"'s public key, and delivering the encrypted session key to the digital media player.

14. The method, as set forth in claim 13, further comprising encrypting blocks of the selected digital media file with the session key.

15. The method, as set forth in claim 12, wherein receiving a unique identifier comprises receiving a unique alphanumeric string associated with a storage media having encoded thereon software that enable communication with the digital media player.

16. The method, as set forth in claim 12, wherein delivering the keys to the digital media player comprises delivering the keys via a secure connection.

18. The method, as set forth in claim 12, further comprising receiving a selection of an entertainment channel associated with a collection of digital media content from the digital media player, and streaming block-encrypted digital media content associated with the selected entertainment channel in response thereto.

19. The method, as set forth in claim 12, further comprising:

receiving a request for streaming digital media content from a digital media player;

determining available resources;

denying the streaming request;

receiving a referral request for streaming digital media content from a digital media player;

determining available resources; and

accepting the streaming referral request.

20. The method, as set forth in claim 12, further comprising receiving a selection of a broadcast channel having a digital media content stream associated therewith from the digital media player, and streaming block-encrypted digital media content associated with the selected broadcast channel in response thereto.

21. A method of providing on-demand online delivery of digital media content, comprising:

transmitting a list of available digital media content to a digital media player over a global computer network for display on a television coupled to the digital media player;

receiving, from the digital media player, a selection of a digital media content from a user; and

streaming the selected digital media content to the digital media player via the global computer network for displaying on the television.

22. The method, as set forth in claim 21, further comprising:

generating a session key and delivering the session key to the digital media player;

encrypting blocks of the selected digital media content; and

streaming the block-encrypted digital media content to the digital media player over the global computer network.

23. The method, as set forth in claim 22, further comprising:

generating a set of unique public and private keys and delivering the keys to the digital media player via the global computer network; and

encrypting the session key with the user'"'"'s public key prior to delivering the session key to the digital media player.

24. The method, as set forth in claim 23, wherein delivering the keys to the digital media player comprises delivering the keys via a secure connection.

25. The method, as set forth in claim 21, further comprising:
