Abstract

A method improves audio acquisition time by nascent signal caching. The receiver system includes the processor which contains the ASRC (Arbitrary Sample Rate Converter), demodulator, channel splitter, channel decoder and middleware & application along with the secondary storage system. The nascent digital broadcast radio signal after the sample rate conversion is cached in a secondary storage and given as input to the demodulator. The demodulator starts the demodulation process over the received signal by utilizing default channel parameters and detects the channel parameters of the received signal. If the default channel parameters are different from the detected channel parameters, the demodulator starts the re-demodulation process with the detected channel parameters over the nascent digital signal cached in the secondary storage, instead of waiting for a subsequently transmitted signal, thereby improving the audio acquisition time.
