Abstract:

This invention describes a system and methods for media content subscription (251) service distribution; typical services include cable television, premium content channels, pay-per-view, XM radio, and online mp3 services. Subscribers use portable electronic devices to store digital certificates (256) certifying the subscriber's privileges and an assigned public key (255). The devices can communicate with specially enabled televisions, radios, computers, or other media presentation apparatuses. These, inturn, can communicate with central databases owned by the provider, for verification purposes. Methods of the invention describe media content subscription (251) service privilege issuing and use. The invention additionally describes methods for protecting media content transmitted to users with a variety of encryption schemes. The invention also comprises methods for subscribed users to bestow a subset of their privileges to a number of secondary users, with appropriate permission from the media content subscription (251) service provider.
