Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes a processor and memory including instructions that, when executed, cause the processor to: determine an initial rating for the media provided in a first geographic area based on return path data (RPD) tuning information obtained from RPD devices in subscriber households in the first geographic area; determine a first panelist rating for the media provided in a second geographic area based on first panel tuning information obtained from first metering devices in a first subset of panelist households in the second geographic area; determine a nonsubscriber calibration factor based on the first panelist rating; and determine a final rating for the media in the first geographic area by modifying the initial rating based on the nonsubscriber calibration factor.

Appropriate control is performed when communication is performed between a plurality of information processing devices. An information processing device performs real-time image transmission with another information processing device according to a Wi-Fi CERTIFIED Miracast specification. The information processing device includes a control unit. The control unit performs control such that setting request information for performing a setting related to the real-time image transmission is received from the other information processing device via an access point. The control unit performs control such that a setting request for performing the setting based on the setting request information is transmitted to the other information processing device through direct communication.

A wireless microphone and/or in-ear monitoring system having at least one first mobile device for wirelessly transmitting first audio signals. The system also has at least one base station for wirelessly receiving the first audio signals transmitted by the mobile device. The wireless transmission is based on an orthogonal frequency-division multiplexing transmission (OFDM) during a time-division multiple access (TDMA) time slot. Each wireless microphone occupies at least one slot within 2 ms. Each of the TDMA frames has a plurality of slots which respectively have precisely one OFDM symbol. Accordingly, precisely one OFDM symbol is transmitted in each TDMA slot. During a time slot made available in accordance with the TDMA, a transmission is effected on the basis of an OFDM method. The TDMA frame length is so short as a latency of <4 ms is required for professional audio transmission, for example in the case of wireless microphone systems.

The present technology relates to a receiving apparatus, a transmitting apparatus, and a data processing method which are capable of providing detailed information of emergency information that is to be announced in case of emergency. The receiving apparatus receives a digital broadcast signal, and performs a process with respect to an emergency information application for presenting detailed information of emergency information on the basis of control information that is included in the digital broadcast signal and that includes information about the detailed information of the emergency information which needs to be announced urgently. The present technology is applicable to a television receiver, for example.

A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of independent units responsive to a broadcast controller. Each independent unit includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a control signal received from the commander. The independent units are configured and operate independent of each other. The broadcast controller transmits wireless signals to the energy controllers of the independent units. The energy controllers do not respond to control signals received from the commanders of other independent units, but the energy controllers of both independent units respond to the wireless signals transmitted by broadcast controller. The energy controller may operate in different operating modes in response to the wireless signals transmitted by the broadcast controller.

A system for peak-to-average-power ratio (PAPR) reduction of a frequency shifted plurality of digital broadcast signals taking into account the combined signal peaks in order to transmit the signals more efficiently in a single broadcast transmission system. The PAPR algorithm takes into account a rotating constellation phase offset for the shifted signals corresponding to the amount of applied frequency shift. In the case of a dual sideband In-Band-On-Channel (IBOC) signal typically used in conjunction with an FM carrier in the center, the sidebands can be interleaved to create a new IBOC signal definition and take the place of the FM carrier for an all-digital transmission that is backward compatible with IBOC receivers allowing for a gradual migration to all digital broadcasting.
