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： This technology relates to a transmission apparatus, a reception apparatus, and a data processing method for easily implementing circuits on the receiving side.
There is provided a transmission apparatus including a processing section configured to process a stream with respect to each of multiple PLPs included in a broadcast signal, the stream being constituted by packets, the processing section further causing a header of each of the packets to include mapping information mapped to identification information identifying the PLP to which each of the packets belongs. This technology may be applied to data transmission methods such as the IP transmission method or the MPEG2-TS method, for example.-

摘要： A configuration is realized in which a packet delimiter can be discriminated from an MMTP packet string including MMT format data, and a packet can be selectively acquired and reproduced. The MMT format data is input through a broadcast wave or the like, a packet length of an MMT protocol (MMTP) packet including the MMT format data is acquired, and recording data in which an additional header storing the acquired packet length is set before the MMTP packet, is generated, and is recorded in an information recording medium. A reproducing device is capable of discriminating a delimiter of each MMTP packet, according to the packet length of the MMTP packet, read from the additional header, is capable of acquiring reproducing data, for example, image data, from the selected packet, and is capable of decoding and reproducing the acquired data.
