RECEPTION APPARATUS AND DATA PROCESSING METHOD

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.
