Apparatuses and methods can be related power down workload estimations using artificial neural networks. Workload estimation can include predicting a duration of a subsequent power down event of the memory device. A quantity of maintenance operations to be performed on the memory device, may be predicted based on the predicted duration of the subsequent power down event, when the memory device is powered on after the subsequent power down event using an artificial neural network. The quantity of maintenance operations may be performed on the memory device prior to the subsequent power down event of the memory device.

A receiving device including a first electronic component and a second electronic component. The first electronic component includes: an analog audio demodulator that demodulates a received signal including a digital broadcast wave and an analog broadcast wave to output an analog audio, the analog broadcast wave being broadcast later by a preset first delay time than the digital broadcast wave; and a transmitter that transmits a communication signal including the analog audio and the received signal to the second electronic component. The second electronic component includes: a receiver that receives the communication signal from the transmitter; a digital audio demodulator that demodulates the received signal included in the communication signal to output a digital audio; and a selector that selects at least one of the digital audio and the analog audio as an output sound signal.

Travel-related-information messages (TRIMS) are received from one or more information sources, and information included in the messages is separated into a first (e.g. TPEG™) or second (e.g. TPEG+) group. A broadcast area to which the information included in the TRIMs is to be broadcast is determined. A further determination indicates that a subset of information assigned to the first group is to be reassigned to the second group. The subset of information is reassigned from the first group to the second group based on parameters associated with the broadcast area. The information included in the first group and the second group is delivered to one or more processing modules that generate a first TRIM reporting message using information included in the first group and a second TRIM reporting message using information included in the second group.

A boundary specifying a bounded geographic area for which travel information is to be reported is generated. Flow section information associated with flow sections located within the boundary is obtained. The flow sections represent portions of one or more roadways assigned relevant functional road classes (FRCs). The flow section information includes information about traffic flow associated with the flow sections. FRC current traffic messages, which include non-predictive traffic information associated with roadway portions that are in the bounded geographic area and are assigned relevant FRCs, are combined with the flow section information to generate a first data group. The first data group is streamed to a first traffic message service.

If reception quality of a broadcast signal of a first frequency received by a tuner satisfies setting conditions, the frequency received by the tuner is changed from the first frequency to a second frequency. It is evaluated whether or not the amount of offset between a reference frequency and the frequency of the signal, which is generated by converting the broadcast signal of the second frequency received by the tuner into an intermediate frequency is within a predetermined range. If the offset between the reference frequency and the frequency of the intermediate frequency signal is within the predetermined range, the data included in the broadcast signal of the first frequency is acquired by a demodulating the broadcast signal of the first frequency. It is evaluated whether or not the broadcast signal of the first frequency is a broadcast signal of a broadcasting station based on the acquired data.

A method of block deinterleaving data received at a digital radio broadcast receiver is described. The method includes providing a block of memory having a n×k addresses, wherein the block comprises a single table, receiving a digital radio broadcast signal at the receiver, and demodulating the digital radio broadcast signal into a plurality of interleaved data units. For at least one series of n×k data units a pointer step size is determined, and for each data unit in the series, an address in the block is calculated based on the pointer step size, and an output data unit is read from the block at the address, such that said output data units represent block deinterleaved data units. An input data unit from the plurality of interleaved data units is then written to the block at the address. Associated systems and computer readable storage media are presented.

Over-the-air radio broadcast signals are commonly used to deliver a variety of programming content (e.g., audio, etc.) to radio receiver systems. Supplemental data (e.g., metadata) may be provided to radio broadcast receiver systems, where such supplemental data is associated with the programming content delivered via the over-the-air radio broadcast signals. In exemplary embodiments described herein, a radio receiver system receives both (i) primary programming content via over-the-air radio broadcast transmission, and (ii) metadata related to the programming content via wireless Internet. This use of metadata provides a user with an enhanced experience regardless of the type of terrestrial broadcast signal that is received at the user's radio receiver system. Users receiving radio broadcast signals at a receiver system may view images, videos, multimedia displays, text, etc., that is related to the programming content received via the over-the-air radio broadcast signals.

A method for processing a digital audio broadcast signal in a radio receiver, includes: receiving a hybrid broadcast signal; demodulating the hybrid broadcast signal to produce an analog audio stream and a digital audio stream; and using a normalized cross-correlation of envelopes of the analog audio stream and the digital audio stream to measure a time offset between the analog audio stream and the digital audio stream. The time offset can be used to align the analog audio stream and the digital audio stream for subsequent blending of an output of the radio receiver from the analog audio stream to the digital audio stream or from the digital audio stream to the analog audio stream.

A low cost DAB multichannel receiver comprising a simplified buffering method for buffering content segments from multiple streams contained within the DAB channel, where the receiver enables the listener to navigate buffered content segments from multiple streams within the DAB channel while enabling the broadcaster to control the timeshift of commercial content to the receiver output stream. The receiver's buffered content grows over time and is cleared when tuning away from the channel, thus encouraging listeners desiring to tune in to new content to instead navigate to new buffered segments. Broadcaster control of the listener experience may be enabled by setting content control fields which are observed in the broadcast by the multichannel receivers. Additional embodiments are disclosed.

A system and method of controlling a digital radio broadcast receiver in a vehicle includes: detecting an instruction to activate the digital radio broadcast receiver; accessing a software application at the vehicle in response to the instruction; and activating the digital radio broadcast receiver in the vehicle at the direction of the software application.
