Mobile Hybrid Radio Receiver Service Following Source Selection

A hybrid radio receiver comprising:

• a radio broadcast receiver to recover audio content from a broadcast radio signal, and to derive a metric that indicates audio quality of the audio content at any given time;
• a network radio to recover audio content from a wireless network connection;
• and
• a controller to perform:
• determining whether the reception metric exceeds at least two different, spaced-apart thresholds within a preconfigured time period;
• and
• deriving a switching decision to use the broadcast radio signal or the wireless network connection as a source of audio content based on a combination of a previous switching decision and the determination that the reception metric exceeds the at least two different thresholds to introduce hysteresis into the switching decision.

A non-transitory computer-readable medium encoded with instructions that, when executed by a processor of a hybrid radio receiver configured to recover audio content separately from a broadcast radio signal and from a wireless network connection, cause the processor to perform:

• at periodic intervals, collecting values of a reception metric that indicates audio quality of the audio content in the broadcast radio signal and, at each interval, performing:
• determining whether the reception metric exceeds each of at least two different thresholds by computing a respective average for each threshold by dividing a number of occurrences in which the reception metric exceeds each threshold at respective periodic intervals by a total number of the periodic interval of the periodic intervals;
• and
• deriving a switching decision to use either the broadcast radio signal or the wireless network connection as a source of audio content based on a combination of a previous source decision and the determination that the reception metric exceeds the at least two different thresholds;
• and
• selecting the source of audio content based on the switching decision.
