摘要： Encrypted content from a content provider is received at a central location of a multichannel video programming distributor (MVPD). The content provider is distinct from the MVPD. The content is decrypted and processed in a virtual set-top application associated with a set-top of a customer of the MVPD. The set-top of the customer is located in a customer premises remote from the central location. The processed content is provided over a secure data link to a conditional-access encoder at the central location. The conditional-access encoder encrypts the processed content, which is then transmitted to the set-top of the customer.

摘要： A system for providing multiple levels of authentication before delivering private content to the client devices over the communications network. A product identifier on the physical product is scanned using a code reader/decoder in the client device to access or request private content from the server. The server receives the device identifier associated with the client device and the product identifier associated with the physical product from the client device over the communications network for authentication. The server processor transmits the requested content, preferably a webpage, to the client device if both the device identifier and the product identifier are authenticated by the server processor.

摘要： Components of a mobile traffic network and components in communication with the network cooperate to confirm whether a mobile station user or account owner has previously purchased media content for a particular mobile station. Media content that has already been purchased by a user can be downloaded by that user to a new mobile station after the initial mobile station is lost, damaged, or upgraded.

摘要： A first user having a certain set of privileges with respect to an initial three-dimensional (3D) model associates a watermark with the initial 3D model, so that the watermark is displayed whenever the initial 3D model is viewed or edited. A second user having a smaller set of privileges with respect to the initial 3D model is permitted to view, copy and/or modify the initial 3D model, but is not permitted to remove or alter the content of the watermark. The watermark is continuously displayed as the second user works with the initial 3D model. When the second user applies a change to the initial 3D model, an indication of the modifications applied by the second user is generated and stored with the model data corresponding to the updated 3D model.

摘要： Direct content redistribution between users belonging to the same community is enabled. A portable telephone set issues a request to a community management server to register portable telephone sets belonging to a community, in association with the community, and the community management server performs community registration. The portable telephone sets issue requests to the community management server for permission to redistribute content which has been distributed from a CP server, and when the redistribution permission request is for registered portable telephone sets belonging to the same community, the community management server grants permission for the redistribution. By this means, content redistribution can be performed directly between users belonging to the same community, without the intervention of the CP server.

摘要： A method is disclosed for a device to interdependently validate a digital content package having a piece of digital content in an encrypted form, and a corresponding digital license for rendering the digital content. A first key is derived from a source available to the device, and a first digital signature is obtained from the digital content package. The first key is applied to the first digital signature to validate the first digital signature and the digital content package. A second key is derived based on the first digital signature, and a second digital signature is obtained from the license. The second key is applied to the second digital signature to validate the second digital signature and the license.

摘要： An information delivery system includes a delivery server and two cellular phones. For example, when one cellular phone accesses the delivery server and requests a delivery of content data such as music data, desired music data is delivered from the delivery server onto the one cellular phone. Meanwhile, if the one cellular phone accesses the delivery server and designates a destination (the other portable phone) and a day and hour of delivery and then executes a schedule of delivery, music data is delivered on a scheduled day and hour from the delivery server to the other cellular phone.

摘要： Systems and techniques are provided for controlling and managing digital assets. These systems and techniques are particularly useful when digital assets are transmitted electronically using, for example, the Internet, as these techniques serve to make the Internet secure for communication and control of digital assets. In addition, they permit dynamic control and management of digital assets, regardless of where the assets reside. Use of these systems and techniques promises to enable new, Internet-based distribution models, and to provide superior insight with respect to the use and status of digital assets. Particular implementations of the systems and techniques permit features such as lifetime control of digital content, multi-level control of digital content (including session encryption, asset encryption, and remote management), and try-before-you buy marketing approaches. They also support functions such as digital rights transfer, tracking, segmentation, archiving, and improved handling of upgrades and updates.
