发明名称 ENCRYPTION METHODS FOR SATELLITE RADIO BROADCASTING
摘要 According to the invention, a subscriber to a first satellite radio service can be provided with an option to receive, over their current receiver unit, supplemental content, such as a particular show or channel, which is otherwise only available within a relevant jurisdiction as part of a subscription package to subscribers of one or more other satellite radio services. Thus, without purchasing a full subscription to another service, the subscriber of the first satellite radio service may arrange to receive supplemental content that is otherwise only available as part of a subscription package, such as a basic or general subscription package, to subscription holders of one or more other services. The invention also provides methods of broadcasting and methods of configuring dedicated and interoperable satellite radio receiver units so that the supplemental content can be received by a subscriber.
