Abstract: A broadcast translator for receiving off-air radio-frequency (RF) signals and retransmitting RF signals may include a tuner and demodulator, a data analyzer, a data converter, and/or an exciter. The tuner and demodulated may be configured to receive an off-air RF signal and output demodulated data. The data analyzer may be configured to receive the demodulated data and analyze the demodulated data to generate new signaling information and control and configuration information. The data converter may be configured to receive the demodulated data and convert the demodulated data into output data packets. The exciter may be configured to receive the new signaling information and the control and configuration information and the output data packets and generate a new RF signal in a same or a different frequency as the off-air RF signal. The new RF signal may include the new signaling information and the control and configuration information.

Abstract: A method for enhanced broadcasting in an ATSC 3.0 system includes: selectively choosing among various input sources available to components within the system, including STLTP (Studio to Transmitter Link Transport Protocol), ALPTP (ATSC Link-layer Protocol Transport Protocol), DS (Data Source), and RF (off-air signals); inserting local content into a broadcast stream by at least one component within the system; and regenerating standard-compliant signaling information to ensure compatibility with ATSC 3.0 standards.

Abstract: The present invention relates to sports training and testing technology and discloses a water training integrated machine for dragon boat racing. The system comprises a dragon boat, a shore data processing device, and a water device. The water device is mounted on a blade of the dragon boat and includes a sensor, a data operation unit, and a communication transmitting module, sequentially connected. These components are powered by a power supply module. The data operation unit communicates with the shore data processing device via the communication transmitting module. The shore data processing device comprises a data processing module, a display module, and multiple communication receiving modules. The display module and communication receiving modules are electrically connected to the data processing module. This technical solution enables accurate measurement and real-time monitoring of stroke force during water sports training, thereby enhancing performance analysis and training efficiency.

Abstract: A system for prioritizing NRT data services within an ATSC 3.0 broadcasting standard includes NRT servers each configured to transmit NRT data; a signaling server operatively coupled to each of the NRT servers and configured to receive the NRT data and prioritize the received NRT data; and a broadcast gateway operatively coupled to the signaling server and configured to receive the prioritized NRT data from the signaling server and convert the prioritized NRT data for transmission to an exciter for ATSC 3.0 broadcasting. The signaling server includes a processor configured to prioritize the received NRT data to produce the prioritized NRT data by: defining a prioritization policy; identifying priorities of the received NRT data and assigning priority according to the prioritization policy across all of the received NRT data; and determining a priority schedule for broadcasting the received NRT data to provide the prioritized NRT data to the broadcast gateway.
