Abstract: A more efficient over-the-air software push can be facilitated by a firmware over-the-air (FOTA) server device in communication with a home subscriber server (HSS). For example, the FOTA server can host the names of user equipment devices that are due for a FOTA update. When a user equipment device identification is received from the HSS, the FOTA server can then check the user equipment device identification against the names within the server. If the name is found, then the system can send discontinuous reception data to the user equipment device to modify a current discontinuous reception value of the user equipment device. Thus, the modified discontinuous reception value can prompt a long reception time of the user equipment device such that the user equipment device can receive the FOTA.

Abstract: A media receiver identifies attributes of a media station to which the media receiver is currently tuned. The media receiver monitors the signal quality of the media station. If the signal quality of the media station drops below a quality threshold, the receiver chooses an alternate station having similar content, and then tunes to the alternate station until the signal quality of the original station improves. When the signal quality of the original station rises above a re-tune threshold, the receiver can switch back to the original station. The receiver can monitor and record user listening patterns, station-switching patterns, and situational parameters, to identify times or locations at which station switches occur. This information can be used to select appropriate alternative stations, to perform pre-emptive station switches, and to determine when a station's content will be buffered with the expectation that a station's signal will drop below the quality threshold.

Abstract: A system and method for assigning received channels to preset tuning keys of a receiver. A series of preset keys are sequentially labeled and one preset key, such as the preset key marked “0,” is a pre-defined preset key. An elongated pressing of the pre-defined key causes the currently tuned channel, if it is not assigned to a preset key, to be assigned to an unassigned preset key. If the currently tuned channel is already assigned to a preset key, pressing the pre-defined key instead causes the currently selected channel to be un-assigned from that preset key. Radios with two tuners that each process different sets of radio signals assign channels for a particular tuner to alternating preset keys, allowing acceleration of sequentially selecting channels assigned to pre-set keys by pre-tuning another tuner to the next channel in the sequence.

Abstract: A waveform shaping circuit wave-shapes a demodulated signal after FM demodulation to generate a binary value. A smoothing circuit smoothes the demodulated signal to generate a reference voltage. A comparator compares the reference voltage with the demodulated signal to output the binary value. A potential difference limiting circuit determines whether a potential difference between the demodulated signal and the reference voltage exceeds a set voltage. When the potential difference exceeds the set voltage, the potential difference is controlled to a value less than the set voltage. At the initiation of signal reception or after a jamming signal stops, the reference voltage follows the demodulated signal, thus allowing data reception to rapidly begin.

Abstract: The invention relates to a method for automatically finding an AM radio program, by which an AM radio receiver is tuned through in discrete steps, such that, for each set AM frequency, the reception quality at the currently set AM frequency is determined, the field strength of the neighboring frequencies is measured. If a significant field strength is detected at the neighboring frequencies, these are taken into account in determining the overall reception quality, in that the reception quality is reduced by a noise value, and subsequently the overall reception quality is compared with an upper quality limit. If the upper quality limit is exceeded, the program search is interrupted, and the AM radio program with this high overall reception quality is played. This method succeeds in reducing the number of misjudgments of AM radio programs with actually poor quality, and thus improves the reproduction quality of an AM radio receiver.
