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.

An input unit 21 receives the input of conventional image-quality playback data adapted to terrestrial digital television broadcast and high image-quality playback data. A combining unit 22 combines the conventional image-quality playback data and the high image-quality playback data. A data configuration unit 23, on the basis of combined data obtained by combining the conventional image-quality playback data and the high image-quality playback data by means of the combining unit 22, generates data for one polarized antenna transmission and data for another polarized antenna transmission.

A transmitting system, receiving system, and a method of processing broadcast signals are disclosed. The method for processing a broadcast signal in a broadcast receiver comprises receiving a DTV signal including a data group, the data group including mobile service data, segmented known data sequences, long known data sequences and transmission parameter data, compensating carrier frequency offset of the DTV signal and channel-equalizing the carrier frequency offset compensated DTV signal using at least one of the long known data sequences and segmented known data sequences in the data group of the DTV signal, wherein the channel-equalizing includes performing a Error Correction (FEC) decoding on data located between the segmented known data sequences, and estimating Channel Impulse Response (CIR) using the FEC decoded data as known data.

Provided are a vehicle and a method of controlling the same that are capable of, when a user having been listening to a radio broadcast in a vehicle desires to send a message to the radio broadcast, providing a service that conveniently and safely sends the message to the radio broadcast when the user utters the message as speech. The vehicle may, based on a predetermined condition being satisfied while the audio corresponding to the radio broadcast signal is being output through a speaker, generate a message signal based on a speech message of the user input into a microphone, and control a communication module to transmit the generated message signal to a broadcasting station that broadcasts the radio broadcast signal.
