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.

Communication service subscription management

An SDARS receiver for use with at least two antennae, each of which receives bitstreams from a first satellite, bitstreams from a second satellite, and bitstreams from a terrestrial repeater, including demodulators configured to switch between demodulating bitstreams from the satellites and to switch between demodulating bitstreams from the terrestrial repeater, and a processor coupled to the demodulators, the processor being configured to switch the demodulators according to a variety of algorithms.

Satellite receiver system

A system optimizes terrestrial signal acquisition in a communication system by initially determining whether a first synchronization signal is available from a first ensemble, which has an associated first programmed content of a terrestrial signal. Next, when the first synchronization signal is not available from the first ensemble, the system switches to a second ensemble of the terrestrial signal to acquire a second synchronization signal, which is synchronized with the first synchronization signal. Finally, the system switches back to the first ensemble to retrieve the associated first programmed content.

System and method for optimizing terrestrial signal acquisition in a communication system

A mobile weather band radio and method of tuning the radio to select a signal channel based on geographic position. The radio has a weather band tuner adjustable for a plurality of radio wave signal channels. A position indicative receiver is provided for receiving position indicative signals and determining a current position of the radio. A controller automatically tunes the tuner to a select signal channel based on the determined geographic region.

Weather band radio and method of tuning same

A mobile weather band radio and method with dynamic geographic message updating. The radio has a weather band tuner for receiving weather band signals containing a message and a geographic identification code. A position indicative receiver is provided for receiving position indicative signals and determining a current position of the radio. Geographic identification codes and electronic map data are stored in memory for defining geographic regions corresponding to the geographic identification codes. A controller determines one of the geographic codes corresponding to the determined current position based on the position indicative signals, and further performs an operation, such as playing the message, when the determined geographic code corresponds to the received geographic code.
