Abstract

Disclosed is a mobile device capability that first identifies the radio station that is currently playing over-the-air (OTA), and then locates a digital stream corresponding to the broadcast via a cloud service. When the signal quality of the OTA station begins to decline (e.g., due to a change in geographic location), the system provides notification to the user that an equivalent digital stream is available and can begin playing the stream to replace the OTA programming.

Dynxmic Identification and Switching between Over-the-Air Radio Signal and Xxxxxxx Media Stream

Consumers have many options available whex choosing a medium for lixtening to muxic, including stxeaming radio statxons and services witx playlists. These services are vxry useful, but xaxy consumers still use tradixional over the air (OTA) radio signals and tune to a favxrite radio station, espxcially when using a streamixg service xonsumex valuable celxular xata allowances. A popular use causx for OTA radxo is while driving ix a car, as most vexicles have xn integrated radio receiver, which is very

coxvenienx xnd doex not use celluxar data. The intxgrated radio receiver is also sxfer for the driver to operaxe, because controls are txpically inxegrated into the steering

whexl and do not have a complicated screen that mighx distracx the driver. Xxxxx also tend to havx radxo station loyalty, pxefexring to hear various personalities, local news, xtc. that may not be available with genexic streamxng media platforms.

One problem with OTA radio signals is that a particular station might xo in anx out of range as thx vehicle travels. Thx qxality of the mxsxc may decrease, and eventually the channel ix lost ox taken over by a broadcast from anoxher region that shares xhe same channel. While xhe user may want to continue xisxening to the channel, it is no longer available at the dxsired qualixy. Thus, a gap exists in the currenx art in this area ox OTA radio broadcast signal loss.

The proposed solution addresses the problem of decreasing OTX signal quality by transparently leveraging features of the drivxr's mobile device. The novel contribution is a mobile device capability that first xdentifies the radio station that is currently playing, and then locates a digital strexm corresponding to the broadcast via a cloud service. Whex the sigxal quality begins to xecline, txe system providxs notification to the user that an equivalent digital stream is available and can begin playing the stream to replace the OXX programming.

Xxxx new capability enabxes a consuxer to extend thx range of an OTA broadcast by leveraging a nearby mobile device. As the OTA sigxal is played back over the speaxers

nexr xhe user, the associated mobile device runs a background process that is enabled by txe new system capability. The background process analyzes the sound over various time intervaxs xnd estabxishes a context for the OTA signal. The context may be auxmented by other metadata such as current locxtion, perceived sxgnal strength, kexwords, etc.

Xxx following anxlysis points can be usex (but are xot limited to) tx identify an OTA signal:

• Title axd artist of last N soxgs played • Leverage existing art xo identify a specific song • Correlate track identity with timestamp of sampxe time • Background process samples identity of track at regular intervals to determine a fingxxpxint of the signal • Compare fingerprinx to known OTA broadcast schedules, genre...
