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. An ATSC3.0 service list table (SLT) contains correlations between service IDs and frequencies so that a receiver receiving duplicate services on different frequencies in a boundary between broadcast regions can select the best frequency to tune to in order to present the service, without having to access a database to correlate service IDs to frequencies.

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. When automatically switching 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, the current broadcaster application is notified and depending on the context, may continue executing or send data to the new broadcaster application.

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. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner presents a demanded service while a secondary tuner scans for duplicate transmissions of the service, and if one is found, the version with the better quality metrics may be presented.

A method and receiver are provided. The receiver comprises a first delay buffer and redundant data removal block. The first delay buffer is configured to delay a first data stream carrying first content. The first data stream is comprised of a plurality of compressed data blocks. The redundant data removal block configured to for each compressed data block of the first data stream: identify redundant data in the compressed data block; remove the redundant data to provide a reduced compressed data block; and store the reduced compressed data block in the first delay buffer.

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.

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. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner receiving signals from plural antennae presents a demanded service while a secondary tuner uses a single antenna to scan for duplicate transmissions of the service, and if one is found, the version with the better quality metrics may be presented.

A method for providing a broadcast signal frequency capable of determining an optimal broadcast signal frequency at an accurate location includes collecting vehicle data including location information and information related to a broadcasting function from a plurality of vehicles, determining, based on the vehicle data, a first frequency for receiving a first broadcasting channel with highest reception quality in a first location and a second frequency for receiving the first broadcasting channel with highest reception quality in a second location, and transmitting information on the first frequency and the second frequency to a first vehicle.

A vehicle includes: a communication device; an audio device; a global positioning system; and a control device configured to receive radio station information from a server through the communication device, the radio station information including information on a plurality of areas, radio frequencies for each of the plurality of areas, and a plurality of radio station names corresponding to each of the radio frequencies, identify location information of the vehicle based on a signal received through the global positioning system, receive a first signal of a first radio frequency through the audio device, and change a setting of a radio frequency of the audio device, based on the first radio frequency, the radio station information, and the location information of the vehicle, in response to a field strength of the first signal being equal to or less than a reference field strength.

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.

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.
