Method and system of sharing a controller for a combined cellular phone and satellite radio
First Claim
1. A combined cellular phone and satellite radio, comprising:
- a cellular phone module having a base band processor;
a satellite radio module having a base band processor, said module comprising circuitry to receive and decode stereo digital audio signals;
a controller module having a digital signal processor (DSP) shared by the cellular phone module and satellite radio module; and
a microphone,wherein the base band processor of the satellite radio module provides a digital audio output to a stereo decoder of the controller module and the base band module of the cellular phone module provides a digital audio output to the stereo decoder, andwherein the stereo decoder multiplexes a microphone input signal received at the microphone with digital audio from the satellite digital radio module or the cellular phone module.

Abstract
A method (300) and system (100) for sharing a controller for a combined cellular phone and satellite radio includes a cellular phone module (102), a satellite radio module (106), and a controller module (108) having a digital signal processor (120) shared by the cellular and satellite modules. A base band processor (118) of the satellite module can provide a digital audio output (107) to a stereo decoder (122) of the controller module and a base band module (112) of the cellular phone module can provide a digital audio output (109) to the stereo decoder. The base band processor of the satellite module can provide compressed audio (111) to the DSP for longer term storage within a memory (129). The DSP can also receive control signaling (113) from the base band processor of the satellite radio module and control signaling (117) from the base band processor of the cellular phone module.
