The present technology relates to a receiving device, a transmitting device, and a data processing method which are capable of providing a broadcast service using a wide bandwidth more flexibly. A receiving device processes a stream in which delivery configuration information indicating that the stream of the broadcast service is delivered across a predetermined frequency band is included in transmission information which is transmitted through an upper layer higher than a physical layer, the stream having a delivery configuration corresponding to the delivery configuration information, so that a broadcast service using a wider bandwidth can be provided. The present technology can be applied to a FW proxy device connected to a network such as, a home LAN, a head end of a cable operator, a base station of a mobile network, or the like.

The present disclosure describes an efficient computer-implemented near-field communication system and method based on broadcasting audio signals for dynamically providing context-related additional content to a mobile device. In embodiments of the present invention, the additional content is mapped to specific audio watermarks and/or triggering commands which are encoded together into a digital signal. Based on continuously scanning the received background noise, an exactly defined frequency range and volume is dynamically selected for broadcasting the signal. Hence, the encoded digital signal is further modulated into an audio signal in the exactly defined frequency range. In embodiments of the present invention, the selected exactly defined frequency range for transmitting the audio signal may preferably be located in the ultrasound and/or infrasound frequency range. In case of transmitting infrasound signals, gyrosensors of the mobile device may be employed as audio signal receivers in embodiments of the present invention. Moreover, in further embodiments of the present invention, audio signal receiver of a mobile device such as gyrosensors or microphones may be switched on by transmitting a command via a wireless network such as Wifi or Bluetooth. Also the information about the selected frequency range and volume for broadcasting the audio signal may be provided to the mobile device via a wireless network in embodiments of the present invention. In response, an audio signal receiver of the mobile device may be tuned to the selected frequency range. The received audio signal is further processed on the mobile device so that the context-related additional content may be displayed and/or rendered.

A communication system allows for clock synchronization between a transmitter and a receiver when switching from transmission of an analog signal to transmission of a digital signal. The system uses clock synchronization during transmission of the digital signal, but the clock synchronization may be lost when switching to transmission of an analog signal. A digital clock synchronization is embedded in the analog signal so that the clock synchronization between the transmitter and the receiver may be reestablished upon switching to a digital signal without any delay in transmission of the digital signal.

One embodiment of the present disclosure provides a wireless audio output device for outputting audio content, comprising: an audio output unit; a communication unit for receiving audio broadcast signals; and a processor for generating a broadcast channel list including one or more output candidate channels from among received broadcast channels corresponding to the audio broadcast signals, outputting the broadcast channel list through the audio output unit, selecting one output channel from the broadcast channel list on the basis of a user input, and outputting audio content corresponding to the output channel through the audio output unit.
