The reception apparatus receives a digital broadcast signal of an IP transmission method that includes time information and a stream of content. The time information includes a seconds field and a nanoseconds field. The reception apparatus then generates a processing clock synchronized with the time information on the basis of the time information included in the digital broadcast signal, and processes the stream included in the digital broadcast signal on the basis of the processing clock. The present technology can be applied to, for example, television receivers conforming to the IP transmission method.

Abstract: 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.
