摘要： The present disclosure describes a reception apparatus that includes demodulation circuitry configured to obtain packets included in a plurality of PLPs (Physical Layer Pipes) of a broadcast stream, and processing circuitry configured to process the packets obtained by the demodulation circuitry. The demodulation circuitry and the processing circuitry are interconnected via a single interface. Each combination of an IP (Internet Protocol) address and a port number of an IP packet or a UDP (User Datagram Protocol) packet included in the plurality of PLPs is unique for each PLP in which the corresponding IP packet or the corresponding UDP packet is included. The processing circuitry is configured to identify a PLP in which one of the packets input via the single interface from the demodulation circuitry is included according to the combination of the IP address and the port number of the one of the packets.
