Abstract: A method and protocol for creating and configuring customized paths, such as channels, for the delivery of electronic content to a variety of devices associated with a user is provided. A content provider may create a channel for each device registered by a user by creating a provisioning Uniform Resource Locator (“URL”) for each device. The user may select certain content to be delivered to a registered device via the channel. The user's device requests a list of feed URLs available to the user by accessing the provisioning URL. A content management program returns the list of feed URLs to the device and the list of feed URLs stored on the device is updated. The electronic content may be distributed through the disclosed protocol directly to the registered device if the device is active, or to a computing device for distribution to passive devices.

Abstract: Aspects of the present disclosure relate to managing licenses for playback of digital content. A license management device may create licenses that determine the number of playback devices that can be authorized by the license. Each license may be included in a corresponding digital content. In addition, each license may be distributed to a set of playback devices. Thereafter, a playback device may playback digital content that includes a license when the playback device stores a matching license. A single license can be used to provide authorization to play digital content from multiple sources and/or multiple types of content. Playback devices can store multiple licenses, which allows playback devices to belong to multiple sets of playback devices authorized to playback various digital content. In one embodiment digital content files can contain multiple licenses to allow the content files to be shared by multiple sets of playback devices.

Abstract: A method and apparatus for digital content license management is disclosed that provides one or more license management devices that manage licenses for playback of digital content. The license management devices create licenses having an associated cardinality that determines the number of playback devices that can be authorized by the license. The license is stored in a set of playback devices, where the number of playback devices in the set corresponds to the cardinality of the license. The license is also included in digital content that the license authorizes for playback. Playback devices that have a license that matches a license included in the digital content are authorized to play the digital content. A single license can be used to provide authorization to play digital content from multiple sources and/or multiple types of content.
