Multimedia network system with content importation, content exportation, and integrated content management
First Claim
1. A multimedia system, comprising:
- at least one control server configured to receive a first request for content from at least one client device via a network;
at least one content server configured to send the content to the at least one client device via the network; and
at least one license server configured to;
receive a request from the at least one client device for a content license, via the network, the content license comprising at least a decryption key, the decryption key being an input parameter of a decryption algorithm associated with the content, the request being based upon a determination by the at least one client device that the content is protected and requires a content license, the request further comprising a public key associated with the at least one client device;
receive information from the at least one client device via the network, the information comprising a user authorization and a device authorization, wherein the device authorization corresponds to a security rating of the at least one client device, the security rating of the at least one client device being based on security specifications of software and hardware of the at least one client device;
evaluate the information according to at least one predetermined criterion;
encrypt the content license with the public key; and
send, after being encrypted using the public key, the content license to the at least one client device via the network.

Abstract
This system provides wired and/or wireless access throughout a multimedia network built on a distributed architecture which can be transparent to the user. This multimedia network includes content which is imported or generated within the network. The system allows for the content provider to determine the license status of content and update the license status of content which was previously provided by that provider. The external content can be accessed in real time or downloaded and stored within the system for later access at the convenience of the user. The usage of some content is controlled by the use of encryption and other protection methods. The system allows for storage of live video by storing the digitized video and allowing the user to control how, when and where the content is viewed. The system makes available multiple multimedia services to all users in the network or connected via the internet.

36. A method, comprising:
-
receiving, in at least one control server, a first request for content from at least one client device via a network; transmitting, by the at least one content server, the content to the at least one client device via the network; receiving, in the at least one license server, a request for a content license from the at least one client device via the network, the content license comprising at least a decryption key, the decryption key being an input parameter for a decryption algorithm associated with the content, the request being based upon a determination by the at least one client device that the content is protected and requires a content license, the request further comprising a public key associated with the at least one client device; receiving, in the at least one license server, information from the at least one client device via the network, the information comprising a user authorization and a device authorization, wherein the device authorization corresponds to a security rating of the at least one client device, the security rating of the at least one client device being based on security specifications of software and hardware of the at least one client device; evaluating, in the at least one license server, the information according to predetermined criteria; encrypting, in the at least one license server, the content license with a public key associated with the at least one client device; transmitting, by the at least one license server, the encrypted content license to the at least one client device via the network; decrypting, in the at least one client device, the content license using a private key associated with the at least one client device; and decrypting, in the at least one client device, the content using the at least one decryption key as at least one input parameter for a decryption algorithm. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
