A media system that includes one or more wireless portions.

Concepts and technologies for video alternate network access points and receivers that enable wireless delivery of video content to multiple customer premises over a service area are provided herein. In an embodiment, a system includes a satellite dish receiver that is configured to receive a satellite video feed, and a video alternate network access point that is communicatively coupled to the satellite dish receiver. The video alternate network access point can perform operations that ingest the satellite video feed directly from the satellite dish receiver. The operations can activate a microcell transceiver embedded within the video alternate network access point, and identify a multicast-broadcast single-frequency network channel. The operations can then transmit, to a video alternate network receiver device from the microcell transceiver, the satellite video feed over at least the multicast-broadcast single-frequency network channel.

A method for processing audio signals in a radio transmitter, includes: receiving an analog audio sample stream and a digital audio sample stream; determining offsets in time between the analog audio stream and the digital audio stream using a normalized cross-correlation of audio envelopes of the analog audio sample stream and the digital audio sample stream; filtering the determined offsets in time to produce filtered offset values; determining an alignment slip adjustment value as a function of the filtered offset values; aligning the analog audio sample stream and the digital audio sample stream using the determined alignment slip adjustment value; and generating a hybrid radio signal for broadcast that includes time-aligned analog audio and digital audio.

An audio system in a motor vehicle includes a loudspeaker, a first tuner, a second tuner and an electronic processor. The first tuner tunes to a first frequency such that content broadcasted on the first frequency is played on the loudspeaker. The second tuner tunes to a second frequency while the first tuner tunes to the first frequency and the content broadcasted on the first frequency is played on the loudspeaker. The electronic processor ascertains a user's preferences for content based upon inputs received from the user before the first tuner tunes to the first frequency. The electronic processor determines, based on the user's ascertained preferences, that the user prefers content being broadcast on the second frequency to the content being broadcast on the first frequency. In response to the determining, the electronic processor begins playing the content being broadcast on the second frequency on the loudspeaker.

A method and corresponding broadcast reception device that includes: an impedance matching circuit for adjusting an input impedance value of the broadcast reception device; and a control unit, wherein the control unit can control the impedance matching circuit so as to adjust the input impedance value to a predetermined reference impedance value when the mode of the broadcast reception device is a mode for receiving a broadcast signal through a cable, and control the impedance matching circuit so as to adjust the input impedance value to be less than the predetermined reference impedance value when the mode of the broadcast reception device is not the mode for receiving a broadcast signal through a cable.

In some examples, an interactive audio system includes a receiver for receiving a broadcasted radio frequency (RF) carrier signal. The system may demodulate a portion of the RF carrier signal to receive a demodulated output signal. For example, the demodulated output signal may include a demodulated audio program having embedded data contained within the demodulated audio signal. The system may extract the embedded data from the demodulated audio program. The system may present information related to the extracted embedded data on a display and/or may send at least a portion of the extracted embedded data to another device.

A method and an apparatus for transmitting broadcast, signals thereof are disclosed. The method for transmitting broadcast signals includes processing input streams into BB frames in PLPs; encoding data of the PLPs; building at least one signal frame by mapping the encoded data of the PLPs; and modulating data in the built signal frame by OFDM method and transmitting the broadcast signals having the modulated data, wherein at least one of the BB frames includes a stuffing field and a first indicator describing whether the stuffing field is included in the BB frame.

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.
