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 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.
