BACKGROUND
[0001] The availability of FM radio stations, or other radio broadcast stations, varies
with geographical location. Prior techniques for selecting preferred stations are
additive, meaning that selected radio stations may be assigned to preset buttons and
thus added to a list of favorite stations. This may be done by performing a scan of
available channels and playing each available channel or a short period of time, during
which a user may press and hold a preset button to assign the station being played
to the selected preset button. In this way, a selected station is added to the list
of stations accessible via the preset buttons. Still further, a computer application
or program may perform an automatic scan of radio stations to produce a list of available
stations. A user may then select stations from the list of available stations to be
added to a list of favorite stations. In both of these examples, the station scan
is initiated by the user, and radio stations must be selected one at a time by the
user to be added to a list of stations.
[0002] It would be useful to provide an improved method for managing a station list.

DETAILED DESCRIPTION
[0007] For simplicity and clarity of illustration, reference numerals may be repeated among
the figures to indicate corresponding or analogous elements. Numerous details are
set forth to provide an understanding of the illustrative embodiments described herein.
The embodiments may be practiced without these details. In other instances, well-known
methods, procedures, and components have not been described in detail to avoid obscuring
the disclosed embodiments described. The description is not to be considered as limited
to the scope of the exemplary embodiments shown and described herein.
[0008] The present disclosure relates to the management of one or more radio station lists
in a wireless receiver. The wireless receiver may be, for example, a dedicated receiver,
a cellular telephone, a personal digital assistant (PDA), a tablet, laptop or other
computer, or some other portable electronic device. In one illustrative embodiment,
a list of preferred radio stations is maintained in the wireless receiver. Upon detection
of a scan event, a tuner scans a band of frequencies to detect available radio stations
and forms a list of available radio stations. Radio stations that fail to meet a preference
criterion are removed from the list of available radio stations to form the list of
preferred radio stations. The list of preferred radio stations is stored in a memory
and may be accessed by a user to select a radio station for playback.
[0009] FIG. 1 is a block diagram of a wireless receiver in accordance with various aspects of the
present disclosure. The wireless receiver 100 includes a scanner 102, a processor
104, a memory 106 and a radio antenna 108. The scanner 102 includes a tuner 110, a
scan controller 112 and a station finder 114. The processor 104 includes an event
detector 116, a station list editor 118 and an analysis module 120. The elements of
the processor 104 may be implemented as software modules executed by the processor.
The tuner 110 receives a broadcast radio signal from the radio antenna 108.
[0010] The broadcast radio signal content may be imbedded using frequency modulation (FM),
amplitude modulation (AM) or other modulation scheme apparent to those of skill in
the art. In the sequel, the broadcast channels of the various radio stations are described
as being multiplexed using frequency division multiplexing. However, other channel
or station multiplexing, such as time division multiplexing or code division multiplexing
may be used. In such cases, scanning over a band of radio frequencies is considered
to be equivalent to scanning over a plurality of multiplexed radio channels.
[0011] When the event detector 116 detects a scan event, the scan controller 112 is activated
causing the tuner 110 to scan a range of radio frequencies. The station finder 114
monitors the output from the tuner 110. If a radio station is found at a particular
frequency being scanned, characteristics of the radio station, including its broadcast
frequency, are stored in memory region 122 of the memory 106 to form a list of available
radio stations. Other information, such as the geographical location of the receiver,
the time the station was found, and/or information from a Radio Data System (RDS)
subcarrier signal may also be stored in the memory 122. The station list editor 118
accesses the memory 122, identifies radio stations of the list of available radio
stations that fail to meet one or more preference criteria and removes those radio
stations from the list of available radio stations. The remaining stations, which
meet the preference criteria, are stored in memory region 124 as a list of preferred
radio stations.
[0012] A user interface 126 enables a user of the wireless receiver to access the list of
preferred radio stations in memory region 124 of the memory 106, retrieve the frequency
of the station and control the tuner 110 to select a desired radio station for playback
using playback circuit 128. The user interface may comprise, for example, dedicated
buttons or other physical controls, a voice interface, or a graphical user interface
displayed on a display screen.
[0013] The analysis module 120 is monitors the output from the tuner 110. This output is
the demodulated signal from the selected radio station. A variety of analyses may
be performed by the analysis module 120. For example, the signal may be analyzed for
signal strength and/or signal quality. The signal may be analyzed to determine a content
classification.
[0014] The playback circuit 128 is responsive to the output from the tuner 110 and may include,
for example, a signal driver circuit for a loudspeaker or for an ear-phone output
socket 130.
[0015] In one exemplary embodiment, the event detector 116 monitors the ear-phone socket
130 and initiates a new scan when an ear-phone is plugged into the socket 130.
[0016] In a further example, the event detector 116 receives information, relating to the
geographic location of the wireless receiver, from a locator 132. The locator 132
may be a Global Positioning System (GPS) receiver. The locator may access a Cell Identifier
of a cellular telephone system. In a cellular network, each base transceiver station
(BTS) broadcasts both a Local Area Identifier (LAI) and a Cell Identifier to its cells.
A wireless receiver within a cell can approximate its actual location using the geographical
coordinates of the corresponding BTS. Similarly, the locator 132 may determine an
approximate location from a Media Access Control (MAC) Identifier or other identifier
received from a nearby wireless network node positioned at a known location.
[0017] In a still further illustrative embodiment, the event detector 116 receives time
information from a clock or timer 134. For example, the event detector 116 may initiate
a new scan at regular intervals or when the time since the last scan exceeds a limit.
[0018] The user interface 126 may be configured to enable a user to store a set of user
preferences in memory region 136 of memory 106. The user preferences may include station
content classifications, for example. In one exemplary embodiment, the user preferences
include one or more content classifications that the user does not wish to be included
in the list of preferred stations. The station list editor 118 accesses user preference
memory 136 and removes stations with the specified content classifications from the
list of preferred radio station. For example, a user may wish to avoid talk radio
stations or country music stations, so stations with these content classifications
are removed from the list. In another example, the user preferences include all one
or more content classifications that the user prefers, in which case with stations
with other content classifications are removed from the list of preferred stations
by the station list editor 118.
[0019] The analysis module 120, the locator 132, the clock or timer 134, and the ear-phone
detector associated with ear-phone socket 130 are all examples of automatic scan event
generators that are capable of automatically triggering the scanner 102 to perform
a new scan for radio stations. User Interface 126 provides a manual scan event generator
that may be employed to initiate a scan. Other scan event generators will be apparent
to those of ordinary skill in the art.
[0020] The processor 104 may be controlled by computer-executable instructions stored in
a non-transitory computer-readable medium such as memory 106. In some exemplary embodiments,
the instructions, when executed by the processor, cause the processor to detect a
scan event and, upon detection of the scan event, scan a plurality of potential broadcast
radio channels to detect available radio stations. For example, the scanner may scan
a frequency band to detect stations multiplexed by frequency. Further instructions
cause the processor to identify radio stations of the available radio stations that
fail to meet a preference criterion, remove the identified radio stations to form
the list of preferred radio stations, and store the list of preferred radio stations
in a memory accessible to the processor.
[0021] FIG. 2 is a flow chart of a method 200 of storing a list of preferred radio stations in
a wireless receiver. The method begins at start block 202. If a scan event is detected,
as depicted by the positive branch from decision block 204, a band of radio frequencies
is scanned at block 206 to detect available radio stations. Each scanned frequency
is monitored to determine if a radio station is available at that frequency, resulting
in the formation of a list of available radio stations at block 208. At block 210,
radio stations that fail to meet a preference criterion are identified and, at block
212, the identified radio stations are removed from the fist of available radio stations
to form the list of preferred radio stations. The list of preferred radio stations
is stored in a memory at block 214, and flow returns to decision block.
[0022] A scan event may comprise the connection of an ear-phone to the ear-phone socket.
That is, a new scan may be performed when an ear-phone is plugged into the wireless
receiver. A new scan may also be performed if a time since a prior scan has elapsed,
or if a signal quality of the radio station being listened to falls below a set threshold.
A scan event may comprise a change in location. For example, a current location of
the wireless receiver may be compared to a location where a previous scan was performed.
If the locations are sufficiently far apart, a new scan may be triggered and the list
of preferred radio stations is updated. A new scan may also be performed when requested
by a user via a user interface of the wireless receiver.
[0023] One or more preference criteria may be used to determine which radio stations should
be removed from, or retained in, the list of available radio stations. Example criteria
include: a minimum threshold of signal quality, the preferred content classifications,
and content classifications to be removed. Content classification include, for example,
'talk radio', 'news', 'jazz', 'rock', 'country', 'religious', 'sports', 'music', etc.
In one embodiment, a content classification is determined from a database of classifications
indexed by broadcast frequency or channel. In a further embodiment, the content classification
is determined from an analysis of signals broadcast from the radio stations. In a
still further embodiment, the content classification is determined from Radio Data
System (RDS) subcarrier signals broadcast from the radio stations.
[0024] Invalid radio stations, that is, stations having no content, may also be removed
from the list of available radio stations.
[0025] In some exemplary embodiments, a locator is used to determine the geographic location
of the wireless receiver when a scan is made. The list of preferred radio stations
may include a broadcast frequency of each radio station and the location of the wireless
receiver when the scan was made.
[0026] FIG. 3 is a diagrammatic representation of several exemplary lists of preferred radio stations.
The figure shows a first list 300, a second list 302 and a third list 304. Each entry
of the first list 300 includes a scan location 306 and a scan time 308, that record
where and when the first list was formed. Each entry 310 in the list 300 includes
a broadcast frequency (or equivalently the broadcast channel) of the radio station.
Optionally, each entry may also include a station identifier, a content classification
and/or other information associated with the station (such as the number of times
a station has been accessed). The stations may be sorted in an ascending or descending
order according to the broadcast frequency associated with each station or according
to the number of times that each station has been accessed. In a further illustrative
embodiment, the scan location and scan time may be listed in each entry 310. The second
list 302, which was formed at a different scan location 312 and at a different scan
time 314, has a similar structure to that of the first list. The second list includes
a number of entries 316, each relating to a preferred radio station.
[0027] In one exemplary embodiment, the first list of preferred radio stations 300 and the
second list of preferred radio stations 302 are compared. If the lists are found to
be substantially similar, the first and second lists are combined or merged to form
a third list of preferred radio stations 304. Lists of preferred radio stations may
be determined to be substantially similar if they have a number of entries in common.
The third list of preferred radio stations 304 comprises a combination of the first
and second lists of preferred radio stations. In the example shown in
FIG. 3, stations with identifiers ID-1, ID-2, ID-4 and ID-5 are common to both the first
list and the second list. The scan location 318 of the third list may be a mid point
between the locations 306 and 312. The scan time 320 of the third list 304 may be
the later, or earlier, of the scan times 308 or 314, or some other time, such as the
time the third list was formed, for example. The entries 322 in third list 304 include
all of the entries from the first list 300 and the second list 302, but redundant
entries have been removed to avoid duplication. Combining the lists reduces the number
of lists and reduces the amount of memory required to store the lists.
[0028] The process of combination may be repeated. For example, the third list 304 may itself
be combined with another substantially similar list.
[0029] Once one or more lists of preferred radio stations are formed, the user may select
a radio station from the list for playback. If multiple lists are formed, the list
made at the location closest to the current location may be presented to the user
as a default list.
[0030] An entry within a list may be designated as a default selection. When the wireless
receiver is switch on, the preferred list may be selected dependent upon the location
of the wireless receiver, and the default selection in that list may be selected as
the initial radio station to be played back.
[0031] FIG. 4 is a flow chart of a method for triggering a scan for available radio stations in
accordance with exemplary embodiments of the present disclosure. The method 400 allows
one more lists of preferred radio stations to be updated when various scan events
are detected and a scan is conducted. A particular exemplary embodiment may detect
one or more types of scan events. Following start block 402 in
FIG. 4, a check is made at decision block 404 to determine if the geographical location of
the wireless receiver has changed exceeding a set amount from a previous scan position.
If the location has changed by more than the set amount, as depicted by the positive
branch from decision block 404, a scan is conducted and then one or more lists of
preferred radio stations are updated at block 406. If the position has not changed
sufficiently, flow continues to decision block 408 where the quality of one ore more
radio signals is checked. If the user is listening to a radio station, the quality
of the radio signal of that radio station is monitored. If the quality of the signal
is below a set threshold, as indicated by a quality measure, the user may be asked
if he or she wishes a new scan of radio stations to be conducted. Upon a positive
answer from the user, a scan is conducted and then one or more lists of preferred
radio stations are updated at block 406, as indicated by the positive branch from
decision block 408. Otherwise, a scan is not conducted and the user continues listening
to the radio station. If the user is not listening to a radio station, the default
radio station may be monitored or, alternatively, each of the radio stations in the
list associated with the current location may be monitored in turn. In one exemplary
embodiment, if quality falls below the set threshold, the monitored station is removed
from the list associated with the current location. Alternatively, a new scan may
be performed. If the quality of the signal is above the set threshold, as indicated
by the negative branch from decision block 408, flow continues to decision block 410
where a check is performed to see if a timed event has occurred. For example, the
timed event may be a scheduled time, such as every hour at 10 minutes past the hour,
or a relative time, such as 30 minutes after a previous scan. If a timed event has
occurred, as depicted by the positive branch from decision block 410, a scan is conducted
and then the list of preferred radio station is updated at block 406, otherwise, flow
continues to decision block 412. At decision block 412 the action of connecting an
ear-phone to the wireless receiver is detected. If an ear-phone connection is detected,
as depicted by the positive branch from decision block 412, a scan is conducted and
then the list of preferred radio station is updated at block 406. Otherwise, flow
continues to decision block 414 where user requests are detected. A scan event may
be requested by a user. For example, a user may interact with a graphical user interface
of the wireless receiver or press a designated button on the wireless receiver to
generate a scan request. If a user request is received, as depicted by the positive
branch from decision block 414, a scan is conducted and then the list of preferred
radio station is updated at block 406. Otherwise, flow returns to block 404 to detect
other scan events. A particular embodiment may be configured to detect one or more
of the scan events shown in
FIG. 4. Scan events other than the examples depicted in the figure may also be detected.
[0032] Scan events may be detected in combination. For example, a new scan may be performed
if an ear-phone and the wireless device is in a new location, or a new scan may be
performed if 25 minutes have elapsed since the
last scan, and the ear-phone is plugged in.
[0033] The wireless receiver disclosed above may be a dedicated radio receiver or a cellular
telephone, a personal digital assistant (PDA), a tablet, laptop or other computer,
or some other portable electronic device able to receive radio broadcasts.
[0034] The implementations of the present disclosure described above are intended to be
merely exemplary. It will be appreciated by those of skill in the art that alterations,
modifications and variations to the illustrative embodiments disclosed herein may
