Patent ID: 7394781

Claim:
A wireless remote controller using a time division protocol to remotely control a satellite radio adapted to perform an audio processing operation for time division multiplexing (TDM) and orthogonal frequency division multiplexing (OFDM) signals respectively transmitted from satellites and a terrestrial repeater by demodulating and digitally processing the TDM and OFDM signals, the remote controller comprising: a transceiver for performing a bi-directional communication through a single channel in such a manner that transmission and reception sides are sync with each other in accordance with a time division duplexing scheme, the transceiver wirelessly transmitting a command from a user, and executing a response received thereto, wherein the transceiver comprises: a microprocessor including a control logic for generating a control signal, a transmission buffer for temporarily storing output data, a reception buffer for temporarily storing input data while storing data produced during processing operations, thereby supporting a protocol processing operation, a serial programming interface (SPI) logic linked to an SPI, and a protocol engine for controlling input and output signals thereof associated with the control logic, in cooperation with the control logic, and analyzing input data, thereby determining a subsequent processing operation; and a Bluetooth radio modem including a system control logic for controlling transmission and reception of signals in accordance with the cooperation of the control logic and protocol engine, a clock generation/distribution unit for sending a clock, received thereto, to the control logic, or generating another clock, and distributing the generated clock, a register file storage unit for storing data set through the SPI, and the SPI for performing a bi-directional serial communication with the register file storage unit to perform a set state checking operation.
