RECEIVING DEVICE, TRANSMITTING DEVICE, AND DATA PROCESSING METHOD
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.
EFFICIENT NEAR-FIELD COMMUNICATION BASED ON AUDIO SIGNALS
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 ultrasound 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.

CLOCK SYNCHRONIZATION WHEN SWITCHING BETWEEN BROADCAST AND DATA TRANSMISSION MODES
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.
RECEIVING DEVICE
A receiving device including a first electronic component and a second electronic component. The first electronic component includes: an analog audio demodulator that demodulates a received signal including a digital broadcast wave and an analog broadcast wave to output an analog audio, the analog broadcast wave being broadcast later by a preset first delay time than the digital broadcast wave; and a transmitter that transmits a communication signal including the analog audio and the received signal to the second electronic component. The second electronic component includes: a receiver that receives the communication signal from the transmitter; a digital audio demodulator that demodulates the received signal included in the communication signal to output a digital audio; and a selector that selects at least one of the digital audio and the analog audio as an output sound signal.
