Abstract:
A system and method for improving the DRM (Digital Radio Mondiale) signal acquisition time stores the demodulated DRM signal and accesses it from memory in order to avoid the additional time taken in waiting for service description channel (SDC) data. The system includes an antenna to receive a DRM signal. A tuner tunes the frequency of receiver to a desired range. An asynchronous sample rate converter (ASRC) converts the sampling rate of the received signal to a demodulator sampling rate. A demodulator demodulates the received signal. A memory stores the demodulated signal for reuse. A channel splitter splits the received signal into a fast access channel (FAC), a service description channel (SDC), and a main service channel (MSC). A channel decoder decodes the channel split data. A middleware and an application to parse and to process the data in order to output the processed data.

Claim (Index 5):
A method for improving acquisition time of a digital radio modiale (DRM) receiver, the method comprising the steps of:\n a. receiving a DRM signal through an antenna ( 10 ) at said receiver ( 100 ); b. tuning said receiver ( 100 ) to a frequency using a tuner ( 20 ); c. converting the sample rate of said DRM signal to a demodulator sample rate using an asynchronous sample rate converter (ASRC) ( 31 ); d. demodulating the signal from said ASRC ( 31 ) using a demodulator ( 32 ); e. storing said demodulated signal on memory- 1  ( 40 ) for reuse, wherein said memory- 1  ( 40 ) is accessed when a first received frame ID is Frame- 0  without SDC data, Frame- 1  or Frame- 2 ; f. splitting said demodulated signal into a fast access channel (FAQ, a service description channel (SDC) and a main service channel (MSC) using a channel splitter ( 33 ); g. decoding channel split data for the split demodulated signal of each channel using channel decoders ( 34 ), wherein when SDC is not available, said channel splitter re-splits the stored data in memory- 1  ( 40 ) and stores MSC data into memory- 2  ( 40 ); h. parsing said decoded channel data and processing said parsed channel data as audio and data in middleware ( 351 ); i. sending said processed data to output devices through an application ( 352 ); and j. outputting said processed data through one or more output devices ( 50 ).
