The present technology relates to a receiving apparatus and a data processing method that can execute delay compensation with more simplified configuration. A receiving apparatus has a delay compensation block configured to delay, on the basis of time information included in a packet to be transmitted for each of a plurality of transmission paths including a broadcasting path, another packet to be transmitted by other transmission path than the reference transmission path with respect to a reference packet to be transmitted by a reference transmission path among the plurality of transmission paths to compensate a delay between the packets to be transmitted for each of the plurality of transmission paths. The present technology can be applied to television receivers having a channel bonding function, for example.

Receiving apparatus and data processing method

A transmission device that generates a transmission identification signal indicating transmission identification information for identifying a transmission device that transmits an orthogonal frequency division multiplexing (OFDM) signal, and that injects a transmission identification signal at a lower level than an OFDM signal corresponding to data to be transmitted into all OFDM symbols of the OFDM signal. The reception device demodulates the OFDM signal after the injection of the transmission identification signal from the transmission device.

Transmission device, transmission method, reception device, and reception method

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.

Data processing device and data processing method

The present disclosure relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method which make it possible to control redundancy of a header in packet communication. A region representing a packet length in a header of a packet is set according to a size of a payload of an input packet. A header of a baseband packet includes a minimum fixed length header including type identification information for identification of a type of the input packet or the stream and information of a packet length of the input packet or the stream stored in a payload of the baseband flame packet.

Transmission apparatus, transmission method, reception apparatus, and reception method

A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system comprises 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.

Receiver and reception method for receiving payload data and emergency information

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.

Data processing apparatus and data processing method

The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that enable channel selection information and time information to be transmitted effectively. A transmission apparatus acquires channel selection information for selecting a service and time information used for synchronizations on a transmission side and a reception side, generates, as a physical layer frame constituted of a preamble and a data portion, the physical layer frame in which specific information including at least one of the channel selection information and the time information is arranged at a head of the data portion right after the preamble, and transmits the physical layer frame as digital broadcast signals. The present technology is applicable to IP packet broadcasting, for example.

A reception apparatus receives a content transmitted in an IP transmission system, acquires, based on first control information that is transmitted in a first layer in a protocol stack of the IP transmission system and includes information indicating whether second control information transmitted in a second layer higher than the first layer exists, the second control information, and controls operations of units that process the content based on the second control information.

Reception apparatus, reception method, transmission apparatus, and transmission method for indicating presence or absence of signaling information in a payload of a packet

The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method that enable efficient data transmission. When a reception apparatus including a processing unit that, when a transmission signal including transmission data is received, processes the transmission signal including a pilot signal on which layered division multiplexing (LDM) has been performed, and demodulates a part of the transmission data included in a second layer which is different from a first layer including the pilot signal, it is possible to efficiently perform data transmission using the pilot signal. The present technology can be applied to, for example, a broadcasting system compatible with a broadcasting method such as ISDB-T, ATSC, and the like.

Reception apparatus, reception method, transmission apparatus, and transmission method

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.

The present technology relates to a transmission device, a receiving device, and a data processing method that enable bandwidth control over PLPs when one frequency band includes the plurality of PLPs. The transmission device determines the number of cells of a component to be transmitted by each of PLPs such that the number of cells in an entire physical layer frame including the plurality of PLPs matches a sum of the number of cells of the plurality of PLPs, and transmits a broadcast stream including the physical layer frame. The present technology can be applied to, for example, a system for transmitting a broadcast stream including a physical layer frame including a plurality of PLPs.
