摘要： The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that allow for reliable notification of a start position of a transport packet or a transport stream during encapsulation of the transport packet or the transport stream in an error correction block.
The transmission apparatus generates an FEC block on the basis of an input packet or an input stream, generates an FEC frame on the basis of the FEC block, and sends the FEC frame. A header of the FEC block includes type identification information identifying a type of the input packet or the input stream, information detecting a header error, and a minimum fixed length header having start position information of the input packet or the input stream stored in a payload of the FEC frame. The present technology is applicable, for example, to data transport.

摘要： The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that can improve transmission efficiency. An encoded signal is generated based on realtime data indicated by a waveform L using a predetermined fixed bit rate as a maximum code amount Sx and the encoded signal into which non-realtime data with an insufficient code amount is inserted is transmitted at the fixed bit rate, as indicated by a range Z12, when a code amount of the generated encoded signal is insufficient for the maximum code amount Sx. The present technology can be applied to broadcasting communication.

摘要： Plural streams are synthesized into one stream, and preferable transmission and reception of the synthesized stream to and from an external device is realized.Transport stream packets of plural transport streams are synthesized to create a synthesized stream, and the created synthesized stream is transmitted to an external device. In this transmission, a count information adding area provided in each of the transport stream packets is brought into a state to which a particular count value is added for each of the transport stream packets of the synthesized stream. This configuration notifies the external device that a function for handling packet order switching based on count information is not provided, and receives from the external device a synthesized stream containing the respective transport stream packets arranged in the same order as the order of the transport stream packets at the time of transmission.

摘要： 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.

摘要： The present technology relates to a data processing apparatus, a data processing method, and a program capable of achieving reduction in costs of a reception device that receives a GSE packet.A GSE-Lite packet construction section constructs GSE-Lite packet including GSE-Lite signaling, which is signaling for identifying whether data is the GSE-Lite packet in a data link layer of an open systems interconnection (OSI) reference model, by using, as a target, only a protocol data unit (PDU) whose maximum size is limited to a predetermined limit size of 4096 bytes or less, where the GSE-Lite packet is a generic stream encapsulation (GSE) packet having the PDU placed in a data field. The present technology can be applied to, for example, a case of transmitting the GSE packet and a case of receiving the GSE packet.
