Abstract: The present technology relates to a data processing apparatus and a data processing method that enable correct clock synchronization by use of clock information. The data processing apparatus receives a digital broadcast signal so as to process content included in the digital broadcast signal and clock information also included therein for use in presentation synchronization on the content and sends via a transmission path the processed content and clock information to another data processing apparatus that presents the received content. On the other hand, the another data processing apparatus receives via the transmission path the content and clock information sent from the data processing apparatus so as to process presentation synchronization on the received content on the basis of the received clock information. The present technology is applicable to data processing apparatuses configured to process content, for example.

Abstract: 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.

Abstract: The present technology relates to a reception apparatus and a data processing method that enable clock synchronization in a more suitable manner. 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.
