    Abstract: A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system includes a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.

    Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that permit efficient transfer of time and other information.The transmission device generates a physical layer frame having preambles and a payload that includes, in the preamble, time information representing time of a given position in a stream of physical layer frames and transmits the physical layer frame. The reception device receives the physical layer frame and performs processes using time information. The present technology is applicable, for example, to IP packet broadcasting.

    Abstract: The present technology relates to a transmission apparatus capable of more flexibly realizing a plurality of multiplexing systems in the same broadcasting system, a transmission method, a reception apparatus, and a reception method.A transmission apparatus generates a physical layer frame multiplexed in a predetermined multiplexing system and including determination information capable of determining a multiplexing system, and transmits the physical layer frame as a broadcasting signal. On the other hand, a reception apparatus receives a broadcasting signal, and determines a multiplexing system of a physical layer frame multiplexed in a predetermined multiplexing system on the basis of determination information included in the physical layer frame acquired from the broadcasting signal, and processes the physical layer frame. The present technology can be applied to transmission systems for terrestrial digital TV broadcasting systems, for example.

    Abstract: The present technology relates to a data processing apparatus and a data processing method that permit enhancement of functional extensibility of apparatuses on a receiving side.A data processing apparatus at a preceding stage receives a digital broadcast signal, processes, of data acquired by a demodulation process of the digital broadcast signal, notification data to be notified to a data processing apparatus at a succeeding stage that performs a process succeeding to the demodulation process, transforms the notification data into a transportable format together with reception data acquired from the digital broadcast signal, and outputs the notification data to the data processing apparatus at the succeeding stage together with the reception data. The present technology is applicable, for example, to a system that includes a demodulation device and a system-on-chip.

    Abstract: The present technology relates to a data processing apparatus and a data processing method that can reduce errors of time arising from accuracy of time information.The data processing apparatus generates signaling including time information having accuracy of time according to a frame length of a physical layer frame and processes the signaling so as to be included into a preamble of the physical layer frame to make it possible to reduce errors of time arising from time information. The present technology can be applied, for example, to a transmitter compatible with a broadcasting method of ATSC3.0 and so forth.

    Abstract: A transmitter transmits payload data using Orthogonal Frequency Division Multiplexed (OFDM) symbols, the transmitter comprising frame builder circuitry configured to receive the payload data to be transmitted and to receive signalling information for use in detecting and recovering the payload data at a receiver, and to form the payload data into frames with the signalling information as a preamble to each of the frames for transmission. Modulator circuitry is configured to modulate one or more first OFDM symbols with the signalling information to form the preamble of each frame and to modulate one or more second OFDM symbols with the payload data to form post preamble waveform of each frame. Transmission circuitry is configured to transmit the one or more first OFDM symbols as a preamble and the second OFDM symbols as the post preamble waveform. The transmitter includes signature sequence circuitry configured to provide a transmitter identifier signature sequence, the transmitter identifier signature sequence being one of a set of signature sequences to represent one of a predetermined set of identifiers which identify the transmitter to a receiver, and a combiner configured to combine the transmitter identifier signature sequence with one or more of the first OFDM symbols of the preamble or one or more additional OFDM symbols of the preamble dedicated to carry the transmitter identifier. A receiver can therefore be configured to identify the one or more of the first OFDM symbols of the preamble or one or more additional OFDM symbols of the preamble dedicated to carry the transmitter identifier, and to identify the transmitter of the received signal from the transmitter identifier sequence.

    Abstract: The present technology relates to a reception apparatus, a transmission apparatus, and a data processing method that can prevent useless discard of packets.The reception apparatus performs an error detection process by using an error detection code included in a header of a transport packet. The plurality of transport packets are provided in a payload of a baseband packet that has gone through demodulation. The transport packets include the header and a payload. The header includes the error detection code. The payload has an IP packet provided therein, and the IP packet includes a UDP packet. The present technology is applicable, for example, to data transport compliant with a broadcasting standard such as ATSC 3.0.
