摘要： The present technology relates to a transmission device and a transmission method, each of which enables to efficiently transfer time information. A physical-layer frame is generated on the basis of an FEC frame obtained from input data. A transmission device that transmits a physical-layer frame includes, in a top area of the physical-layer frame, time information indicating the time of a starting position of the top area, which enables to efficiently transfer the time information. The present technology can be applied to, for example, data transfer corresponding to a predetermined broadcasting method.

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： A reception apparatus includes a demodulation circuit configured to demodulate packets obtained with respect to each of multiple PLPs included in a broadcast signal; and a processing circuit configured to process the packets demodulated by the demodulation circuit. The demodulation circuit and the processing circuit are connected with each other via a single interface or interfaces fewer than the number of the PLPs. The demodulation circuit adds identification information to a specific packet among the packets obtained with respect to each of the PLP, the identification information identifying the PLP to which each of the packets belongs. The processing circuit identifies the PLP to which belongs each of the packets input from the demodulation circuit via the single interface or the interfaces fewer than the number of the PLPs, based on the identification information obtained from the specific packet.

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.
