摘要:
Techniques enable seamless movement and consumption of licensed digital content amongst multiple devices. In some embodiments, these techniques allow establishment of a domain capable of having multiple member devices. Each member device of the domain typically comprises a content-consuming device such as a personal computer, a portable media player, or the like. These techniques enable a license associated with digital content to bind to a domain rather than an individual device. As such, each member device of the domain may contain a domain identity and, with the identity, may consume the content with use of the license and in accordance with policy described in the license. These tools may also enable a member device to join multiple domains and to contain an identification of each of these multiple domains.

A method of registering network devices in a digital rights management system (DRMS) includes receiving a digital certificate transmitted by the network device requesting registration and verifying the validity of the certificate. The DRMS may then send cryptographic information to the applying network device. The network device may be authorized for registration via a user interface to the DRMS. The DRMS may conduct a proximity test to determine of the network device is proximate to the DRMS. If the certificate is validated, authorization is received, and the proximity test indicates that the network device is proximate to the DRMS, the network device may be registered. A registered network device is then authorized to play protected digital content.

A digital license includes an identification of a removal service that can authorize removing such license. A client selects the license to be removed and the service, constructs a challenge including therein a challenge license identification block (LIB) identifying the license to be removed, and sends the challenge to the service. The service receives the challenge, stores at least a portion of the challenge in a database, constructs a response corresponding to the challenge and including therein a response LIB identifying the license to be removed and an identification of the service, and sends the response to the client. The client receives the response, employs the response LIB from the response to identify the license to be removed, and removes the identified license upon confirming that the identification of the service in the identified license matches the identification of the service in the response.

摘要:
Metered data is accumulated and is indexed within a metering database of a client according to a metering ID (MID) and a content-associated ID (KID). The client selects a particular MID and metered data in the metering database having the selected MID, and constructs a challenge based on the selected metered data and sends same to a metering service. The metering service obtains the metered data from the challenge, stores same, and constructs a response. The client receives the response including a list of KIDs of the selected metered data in the challenge, and processes the list of KIDs by, for each KID in the list, deleting the metered data from the metering database having the selected MID and the KID.

Described herein are one or more implementations for transforming (e.g., transcoding) DRM-protected digital media content while retaining associated DRM-information (e.g., a user license its related information).
