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.

An apparatus for determining a set of transmit parameters capable of improving and/or optimizing data throughput to a destination device. The apparatus includes an input circuit that receives a signal containing a plurality of data blocks for use by a plurality of devices. At least one of the data blocks is associated with the apparatus and encoded using a first set of transmit parameters. A transmit parameter processor determines a signal to noise ratio value for the received signal and a block error rate value for the at least one data block and at least one other data block encoded using a different set of transmit parameters. A processor generates a request for encoding subsequent data blocks destined to the apparatus using a second set of transmit parameters. A method and system are also disclosed.

A digital receiver for processing a broadcast signal includes a receiving module configured to receive the broadcast signal. Further, the broadcast signal includes service components of a broadcast service, service layer signaling (SLS) information for the broadcast service and a service list table for providing bootstrap information, and the service components include at least one of audio or video data. Further, the bootstrap information is different based on a type of delivery protocol of the SLS information, and the type of delivery protocol corresponds to either a Real-time Object delivery over Unidirectional Transport (ROUTE) protocol or a Moving Picture Experts Group (MPEG) Media Transport Protocol (MMTP). The digital receiver also includes a processor configured to process the service list table, the SLS information and the service components of the broadcast service.

A transmission/reception installation for microwave radio signals, including a unit for transmission/reception including a receiver for receiving the electric signals from the conversion of radio signals received via a terrestrial or satellite link, referred to as forward-link signals, a demodulator for demodulating the electric signals using a first modulation/demodulation protocol, a modulator for modulating electric signals using a second modulation/demodulation protocol that is different than the first protocol, the second protocol being a spread-spectrum protocol, the modulator modulating the signals demodulated by the demodulator, and a converter for converting the electric signals modulated using a spread-spectrum protocol into radio signals that can be transmitted via a satellite link. The installation also includes one or more boxes including a modulator for modulating the electric signals using the first modulation/demodulation protocol, and a coaxial cable connecting the unit for transmission/reception to the boxes.

A server device that includes a receiving unit, a browse page creation unit, a mail creation unit, and a mail transmission unit. The receiving unit receives an image transmitted from an electronic camera via a wireless network. The browse page creation unit creates a browse page for browsing the transmitted image from the electronic camera, the image having been received by the receiving unit. The mail creation unit creates a notification mail for introducing the browse page that has been created by the browse page creation unit to a person other than a user of the electronic camera. Furthermore, the mail transmission unit transmits the notification mail that has been created by the mail creation unit to a specified mail address.
