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.

A method for equalizing an audio frequency signal broadcast in a broadcasting environment. Such a method includes: estimating a frequency profile of a noise signal representing a background noise present in the broadcasting environment, based on, on the one hand, a signal captured by at least one microphone implemented in the broadcasting environment and, on the other hand, the audio frequency signal; determining a desired frequency profile for the broadcast audio frequency signal; determining an acoustic frequency mask representing, for each frequency component, a difference between the frequency profile of the noise signal and the desired frequency profile; and equalizing the audio frequency signal via a weighting of a spectrum of the audio frequency signal by applying a frequency weighting mask that is a function of the acoustic frequency mask, delivering the equalized audio frequency signal.

A network device is configured to receive information regarding a group of content streams and determine a buffer size for each of the content streams. The network device is further configured to receive the content streams from one or more encoding devices. The network device is further configured to buffer an amount of each of the content streams based on the respective buffer size. The network device is further configured to send a first content stream to a user device. The network device is further configured to determine that the first content stream has a quality of experience issue and send the second content stream to the user device.

Disclosed herein is a music service that enables consumers listen to a broadcast radio station without commercials. The service operates by shifting the source channel of a radio from the broadcast radio to a streaming audio service for the duration of the commercial. In some embodiments, the service utilizes any of: a radio including native firmware/software, a mobile device such as a smart phone executing an application, cooperative integration of a radio and a mobile device, or master/slave relationship between a mobile device and a radio. The mobile device listens to the radio broadcast and determines when to shift between the radio broadcast and the streaming audio via any of audio fingerprint analysis, radio station behavioral analysis, radio station metadata, and/or radio station voice recognition analysis.
