ATSC over-the-air (OTA) broadcast of public volumetric augmented reality (AR)
Techniques are described for using the Advanced Television Systems Committee (ATSC) 3.0 television protocol to deliver volumetric information for presentation on various displays using ATSC over-the-air communications channels.
System and method for large data transmission in digital radio broadcasting
Large data transmission in digital radio broadcasting system and method are disclosed. A first channel information of tuned frequency indicates the availability of the data distribution table. Second channel information contains the data distribution info table (list of frequencies mapped to data chunk identifiers). Data chunks have a unique id. Digital broadcast radio receiver receives data distribution tables and parses through the currently tuned frequencies data distribution table. The receiver has information on how to collect the distributed data. Receiver uses its primary tuner to receive the data chunks in the current tuned frequency. Rest of the data chunks are collected by the background tuners in a parallel fashion by tuning to required frequencies. Once all chunks are collected, data file is reconstructed and available for presentation to the user.
Receiving 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.

Method for receiving emergency information, method for signaling emergency information, and receiver for receiving emergency information
A device may be configured to parse a syntax element specifying the number of available languages within a presentation associated with an audio stream. A device may be configured to parse one or more syntax elements identifying each of the available languages and parse an accessibility syntax element for each language within the presentation.

CLOCK SYNCHRONIZATION WHEN SWITCHING BETWEEN BROADCAST AND DATA TRANSMISSION MODES
A communication system allows for clock synchronization between a transmitter and a receiver when switching from transmission of an analog signal to transmission of a digital signal. The system uses clock synchronization during transmission of the digital signal, but the clock synchronization may be lost when switching to transmission of an analog signal. A digital clock synchronization is embedded in the analog signal so that the clock synchronization between the transmitter and the receiver may be reestablished upon switching to a digital signal without any delay in transmission of the digital signal.
Portable sensor fusion broadcast system for maritime situational awareness
Described are portable sensor fusion broadcast systems and devices including a communications module, a sensor fusion module, and a broadcast module.
Alternatives to satellite signals for synchronization in macro network
Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality.
