发明名称 Transmitter, transmission method, and non-transitory computer-readable medium storing program
摘要 A transmitter is connected to a master device, and wirelessly transmits a timing packet, which is transmitted from the master device, to a receiver. The transmitter includes: an input unit for receiving an input of a timing packet from the master device; a delay compensation unit for obtaining a packet length of the timing packet and a modulation system used for radio transmission, calculating a device-specific delay value and a first propagation delay value based on the modulation system and the packet length, and calculating a delay compensation value based on the device-specific delay value and the first propagation delay value; a filter unit for adding the delay compensation value to a specific field of the timing packet; and an output unit for outputting the timing packet to the receiver.

主权项 1. A transmitter comprising: an input unit configured to receive an input of a timing packet from a master device; a delay compensation unit configured to receive the timing packet forwarded by the input unit, configured to extract a packet length from the received timing packet, configured to calculate a device-specific delay value based on a modulation system type used to transmit the timing packet, configured to calculate a first propagation delay value based on the modulation system type and the extracted packet length, and further configured to calculate a delay compensation value based on the device-specific delay value and the first propagation delay value; a filter unit configured to revise the timing packet forwarded by the input unit by adding the delay compensation value to a specific field in the forwarded timing packet; and an output unit configured to receive the revised timing packet forwarded by the filter unit and transmit wirelessly the received timing packet to a receiver.
