A broadcast receiving apparatus includes: a tuner configured to receive a transmission wave in which identification information is stored in a carrier, the carrier being modulated differently from a data carrier, a frequency band when the transmission wave is transmitted in an air being able to be identified by the identification information; and a controller. The controller is configured to identify a frequency band when the transmission wave is transmitted in the air by using the identification information contained in transmission wave received by the tuner.

A system for broadcasting that includes a watermark payload.

Some examples include receiving audio content through a microphone of an electronic device and determining whether embedded data is included in the received audio content. The electronic device may decode the received audio content to extract the embedded data. In addition, the electronic device may perform at least one of: sending a communication to a computing device over a network based on the extracted embedded data, or presenting information on a display of the electronic device based on the extracted embedded data.

A method and system is presented for coordinating the transmission of supplemental digital data to accompany broadcast data, and in particular, analog radio broadcasts, among a plurality of broadcasters. The supplemental digital data may provide information about the particular broadcast data being transmitted (i.e. cut data) or may be supplemental to such data (i.e. news, weather and traffic data). The supplemental digital data to be presented is sorted based on particular algorithms which may take into account broadcaster-specified criteria such as target audience, time of day, type of broadcast data presented, and the like. The supplemental digital data may be audio data, visual data, or audio-visual data for presentation with the broadcast data. The supplemental digital data may further be advertisement data. The advertisement data may be sold by the broadcasters or the party coordinating the IBOC transmission of the supplemental digital data. The supplemental digital data may play simultaneously with muted broadcast data or at a user-specified time.

A system includes a processor configured to determine that transmission data indicates that first data was transmitted via a digital radio channel and that reception data indicates that second data was received via the digital radio channel. The first data is transmitted concurrently with transmission of an analog signal. The processor is configured to detect an error in transmission of the first data based on a comparison of adjacent portions of the first data to non-adjacent portions of the second data. The processor is configured to, in response to detecting the error, initiate display of a default image concurrently with output of an audio signal that is based on the analog signal and to initiate retransmission of the first data to cause second particular data to be output subsequent to the output of the default image. The second particular data corresponds to the retransmitted first data.

A first device listens for a communication token across an audio bandwidth covering a transmit frequency one or more audio frequency broadcasting device. The first device receives at least one token broadcast from the one or more broadcasting devices. The first device demodulates and decodes each received token. One or more computing devices validates each decoded token. The first device determines, based on the validating, a broadcasting device of the broadcasting devices with which to establish a communications channel The one or more computing devices generates a response token based on the token received from the determined device. The first device broadcasts the generated response token in a response band of the determined device. The determined device demodulates decodes, and validates the token broadcast from the first device. Upon determining the token broadcast from the first device valid, the first device and the determined device establish a wireless communication channel.
