A vehicle includes a plurality of broadcast reception antennae; a speaker; and an audio-video-navigation (AVN) device electrically connected to the plurality of broadcast reception antennae and the speaker; wherein the AVN device is configured to receive broadcast signals of a plurality of different frequencies from the plurality of broadcast reception antennae, synthesize the broadcast signals of different frequencies, and provide the synthesized broadcast signal to the speaker to output a sound corresponding to the synthesized broadcast signals.

In order to assist a user in a vehicle with at least one radio station, at least one preference of the user is determined using preferences of pre-stored clusters of plurality of users. Each of the pre-stored clusters includes users with similar preferences related with listening to radio stations. Further, at least one radio station from one or more potential radio stations available for the user is selected based on the at least one preference. The at least one radio station is assisted to the user in the vehicle.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A receiver, to automatically switch from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, can consider not just signal strength and error rates of two frequencies carrying the same service to select which frequency to tune to, but also relative location and direction of motion of the receiver with respect to each broadcaster.

The present disclosure relates to a method for operating a wireless receiver to receive station signals from transmitting stations via communication channels and to emit a selected one of the station signals.

The method selects communication channels to transmit the selected one of the station signals, detects reception properties for the selected communication channels, detects position data of the wireless receiver, assigns the position data of the wireless receiver to the reception properties detected with regard to the selected communication channels,
determines a position-related received data set for the selected one of the station signals, and transmits the position-related received data set to a server device that stores the position-related received data set to be retrievable by the server device.

Broadcast positioning systems supporting location services through over-the-air broadcast television (TV) signals are disclosed. The broadcast positioning system supports a broadcast TV signal format that includes a transmission time of the broadcast TV. The transmission time of the broadcast TV signal is used by a TV signal receiver to determine the propagation delay of the broadcast TV signal between the TV signal transmitter and the TV signal receiver. The TV signal receiver is also configured to receive multiple broadcast TV signals from multiple TV broadcasters, wherein the same delay of arrival for those broadcast TV signals can be determined. In this manner, the TV signal receiver can use the determined multiple delays of arrival from the multiple received broadcast TV signals as time-of-arrival (TOA) and the known locations of the antenna radiating these multiple broadcast TV signals to perform a trilateration or multilateration calculation to determine its position.
