11. A digital radio receiver system comprising:
a demodulator to receive a nascent digital broadcast radio signal after sample rate conversion is performed by an arbitrary sample rate converter (ASRC); and
a secondary storage to cache the nascent digital broadcast radio signal after the sample rate conversion, wherein the secondary storage is connected to the demodulator,
wherein the demodulator starts a demodulation process over the received nascent digital broadcast radio signal by utilizing default channel parameters and detecting channel parameters of the received nascent digital broadcast radio signal,
wherein the demodulator registers a difference between the default channel parameters and the detected channel parameters, and
wherein the secondary storage enables re-demodulation over the nascent digital broadcast radio signal with the detected channel parameters.
