Abstract
Multiple receivers may be enabled to receive satellite-based digital audio radio (SDAR) services under a single subscription. For example, an SDAR service provider can enable multiple vehicles, a home-based digital radio, or a portable digital radio, singly or in any combination. Multiple receivers transmit information to each other. One receiver is designated as a primary receiver, and the other receivers are designated as secondary receivers. The SDAR service provider transmits a list of associated secondary receivers to the primary receiver. The primary receiver enables the associated secondary receivers to receive SDAR services by placing them in an authorized state. The secondary receivers must periodically communicate with the primary receiver to remain authorized. A secondary receiver that fails to communicate with the primary receiver within a prescribed time period is switched to an unauthorized state. In this unauthorized state, the secondary receiver no longer performs as an authorized receiver.
