A system includes a host device to provide a content signal, an end device to receive the content signal, and a branch of amplifiers connected between the host device and the end device to carry the content signal from the host device to the end device. The host device may receive a first signal from the branch of amplifiers connected to the end device, and extract, from the first signal, first characteristics of the content signal measured at one or more points in the branch of amplifiers. The host device may compare the first characteristics of the content signal to second characteristics.

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.
