  • Patent number: 10735232
    Abstract: The present technology relates to a data processing apparatus and a data processing method which can enhance multipath propagation resistance. When performing modulation processing on a physical layer frame including a preamble, which includes a modulation parameter, and one or more subframes, which include data, the data processing apparatus can set any modulation parameter for each subframe, and the modulation parameter has a relationship of Tui/Dxi?Tui+1/Dxi+1 in a case where an effective symbol length indicating a length of an effective symbol is Tui and an interval between pilot signals in a frequency direction is Dxi in an i-th (i is an integer equal to or greater than 0) subframe. The present technology can be applied to, for example, data transmission compliant to a broadcast standard such as ATSC 3.0.

  • Publication number: 20200202609
    Abstract: An information processor acquires information regarding a position and exterior appearance of a target object in a real space, places multiple virtual volume elements in a virtual space at positions corresponding to at least along the exterior appearance of the target object in the real space determined by the acquirer and generates virtual space information representing the target object as a cluster of the virtual volume elements. The information processor detects time variation information of the virtual space information representing shift of at least a portion of the virtual volume elements and estimates positions of the virtual volume elements after a predetermined time duration based on the detected time variation information.

  • Publication number: 20200126280
    Abstract: A position data acquiring unit 200 acquires position data indicating a position of a real object. A delay deriving unit 206 derives delay time in an information processing system 1. A motion predicting unit 300 predicts a movement of the object, and identifies an object position at a future time on the basis of the position data acquired by the position data acquiring unit 200, the predetermined length of time being equal to or longer than the delay time. An image generating unit 302 generates a prediction image in which the object position at the future time is reflected. A display image providing unit 204 acquires the generated prediction image, and provides the prediction image to an HMD.

  • Publication number: 20180324499
    Abstract: The present technique relates to a data processing apparatus and a data processing method each of which enables a burden imposed on processing on a reception side to be reduced. A data processing apparatus produces signaling containing a Null cell number exhibiting the number of Null cells of cells of a sub-frame included in a physical layer frame, and processes the signaling so as for the signaling to be contained in a preamble of the physical layer frame, thereby enabling a burden imposed on processing on a reception side to be reduced. The present technique, for example, can be applied to data transmission complying with the broadcasting standards such as ATSC3.0.

    Abstract: A communication apparatus performs communication while suppressing an increase in power consumption. The communication apparatus includes a periodic signal generating unit, a clocking unit, a multiplication unit, and a communication processing unit. The periodic signal generating unit generates a predetermined periodic signal. The clocking unit clocks time in synchronization with the predetermined periodic signal generated by a frequency signal generating unit. The multiplication unit multiplies the predetermined periodic signal generated by the frequency signal generating unit to supply the signal as a multiplied signal. The communication processing unit performs predetermined communication processing in synchronization with the multiplied signal generated by the multiplication unit.

  • Publication number: 20180262802
    Abstract: The present technique relates to signal processing apparatus and method, and a program that can reduce power consumption. A receiver that receives a broadcast signal includes a demodulation unit that demodulates the broadcast signal, and a reception control unit that controls the demodulation by the demodulation unit. In a section not including PLPs to be received in the broadcast signal, the reception control unit controls the demodulation unit to stop the demodulation by the demodulation unit on the basis of subframes or OFDM symbols. The present technique can be applied to a receiver.

  • Patent number: 9742530
    Abstract: An arrangement for detecting signaling data from bootstrap Orthogonal Frequency Division Multiplexed (OFDM) symbols in the frequency domain, which can provide a more accurate estimate of the signaling data than other arrangements that operate in the time domain. The arrangement includes detecting a cyclic shift of a signature sequence, which has been applied to represent the signaling data, as an average phase change between each of the sub-carriers of the bootstrap OFDM symbol. As a result the signaling data can be more accurately detected or detected at lower signal to noise ratio.
