Systems and methods for one-way time transfer using physical layer signaling are disclosed herein. According to some examples, a method includes generating timing information based on a clock of a transmitting device, where the timing information comprises a timestamp and metadata. The method further includes generating a preamble of a frame, where the preamble includes the timestamp and the metadata of the timing information. The method also includes forming a frame, where the frame comprises a bootstrap, the preamble, and a payload, and transmitting the frame to a receiver device. The one-way time transfer systems and methods of this disclosure can serve mobile devices that entail quick and reliable establishment of a clock.

Systems and methods that realistically simulate traffic in a communications network.

A communication system that involves superimposing data over DC power. The data takes the form of high bitrate digital signals, where the bitrate is much higher than 0 Hz (DC); this separation allows the AC signal to be easily separated from the DC power. The physical system consists of a two conductor cable, and integration is modular, in that multiple slaves can be connected and disconnected to a master through a routing bus also comprising two conductors. The master can communicate bi-directionally with the slave(s), and the data is encoded using DC-balanced encoding in an FPGA. The data is sent to and from a differential signaling transmitter/receiver pairs at each end of the cable. The system is may be used with position sensors, and provides the benefit of reducing cable costs and sensor size due to the decrease in number of conductors and elimination of power components in the sensor.

A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

A system and method enabling the automated installation and configuration of satellite system premises device. The system and method provide for tuning, locking and recognizing particular types of satellite system signals, and then responsively configuring and installing a premises device. The disclosed technology is capable of adapting to both one and two cable satellite premises systems, and is compatible with wideband low-noise block signals, as well as universal low-noise block and single-cable second-generation satellite signals.

A display controlling method for a broadcast receiving apparatus allowed to receive IP simultaneous broadcasting of a 4K broadcasting service via a communication transmission line, in which simultaneous broadcasting of the 4K broadcasting service and a 2K broadcasting service is executed by a broadcasting wave, is configured to: receive and demodulate the 4K broadcasting service, and display a broadcasting program of the 4K broadcasting service; and select and execute one display switching process of first and second display switching processes in accordance with priority order in a case where a defect occurs in reception, demodulation, or display of the 4K broadcasting service, the 2K broadcasting service being received and demodulated to display a broadcasting program of the 2K broadcasting service in the first display switching process, the IP simultaneous broadcasting being received and demodulated to display a program of the IP simultaneous broadcasting in the second display switching process.

A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

Disclosed is an over-the-air (OTA) antenna meter application (meter app) that wirelessly connects to an OTA antenna meter (meter) installed with an OTA antenna and presents information that facilitates a user in installing the OTA antenna at the premises of a customer. For example, the meter app can help the user in pointing and peaking the OTA antenna for one or more broadcast channels, e.g., those selected by the customer. The meter app can store installation information of the OTA antenna for various installations, which can be used in generating a recommendation of, or predicting, installation information for installing the OTA antenna at a specified address. The predicted installation information can include broadcast channels that would be available for reception at the specified address and their signal strength, a specific location of installation on the premises, or whether a pre-amplifier and/or filter is required.
