Delay adjustment using sample rate converters

A method, comprising:

• a radio receiver receiving a first data stream corresponding to content extracted from a first radio signal, wherein the radio receiver includes a first sample rate converter that outputs the first data stream at a first sampling rate;
• the radio receiver adjusting the timing of the first data stream relative to a second data stream having identical content to the first data stream, wherein the adjusting comprises changing the first sampling rate of the first sample rate converter;
• receiving first program data extracted from an analog radio signal and second program data extracted from a digital radio signal simulcast with the analog radio signal;
• and
• selecting one of the first program data and the second program data to provide as the first data stream.

A radio receiver, comprising:

• a first sample rate converter coupled to receive a first data stream corresponding to program content extracted from a first radio signal, wherein the first sample rate converter is configured to output the first data stream at a first sampling rate;
• and
• a delay estimation unit configured to determine a delay of the first data stream relative to a second data stream, wherein the delay estimation unit is configured to provide an indication of the delay to the first sample rate converter;
• wherein the first sample rate converter is configured to adjust the delay based on the indication by changing the first sampling rate;
• wherein the first sample rate converter is coupled to receive the first data stream from a first selection unit, and wherein the radio receiver further includes a second selection unit coupled to provide the second data stream;
• and
• wherein the first selection unit and the second selection unit are each configured to receive a first digital representation of program content extracted from an analog radio signal, and a second digital representation of the program content extracted from a digital radio signal.
