Abstract: 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.

Abstract: The present technology relates to a transmission apparatus capable of more flexibly realizing a plurality of multiplexing systems in the same broadcasting system, a transmission method, a reception apparatus, and a reception method.A transmission apparatus generates a physical layer frame multiplexed in a predetermined multiplexing system and including determination information capable of determining a multiplexing system, and transmits the physical layer frame as a broadcasting signal. On the other hand, a reception apparatus receives a broadcasting signal, and determines a multiplexing system of a physical layer frame multiplexed in a predetermined multiplexing system on the basis of determination information included in the physical layer frame acquired from the broadcasting signal, and processes the physical layer frame. The present technology can be applied to transmission systems for terrestrial digital TV broadcasting systems, for example.

Abstract: The present technology relates to a data processing apparatus and a data processing method that permit enhancement of functional extensibility of apparatuses on a receiving side.A data processing apparatus at a preceding stage receives a digital broadcast signal, processes, of data acquired by a demodulation process of the digital broadcast signal, notification data to be notified to a data processing apparatus at a succeeding stage that performs a process succeeding to the demodulation process, transforms the notification data into a transportable format together with reception data acquired from the digital broadcast signal, and outputs the notification data to the data processing apparatus at the succeeding stage together with the reception data. The present technology is applicable, for example, to a system that includes a demodulation device and a system-on-chip.

Abstract: A first video stream having video data of a first view, a second video stream having video data of a second view, and an audio stream having audio data of an object sound source and positional information based on the first view of the object sound source are generated. A container of a predetermined format including the first video stream, the second video stream, the audio stream, and position correction information for correcting the positional information of the object sound source to positional information based on the second view is transmitted. Thereby, it is possible to accurately perform 3D audio rendering even in a case that view switching is performed at a reception side.

Abstract: The present technology relates to a transmission device, a receiving device, and a data processing method that enable bandwidth control over PLPs when one frequency band includes the plurality of PLPs. The transmission device determines the number of cells of a component to be transmitted by each of PLPs such that the number of cells in an entire physical layer frame including the plurality of PLPs matches a sum of the number of cells of the plurality of PLPs, and transmits a broadcast stream including the physical layer frame. The present technology can be applied to, for example, a system for transmitting a broadcast stream including a physical layer frame including a plurality of PLPs.

Abstract: There is provided a transmission device including circuitry configured to generate a physical layer frame. A time information descriptor is included in a preamble of the physical layer frame. The time information descriptor includes a time information flag that indicates presence or absence of time information in the time information descriptor. The circuitry is configured to transmit the physical layer frame including the preamble and a payload. The time information indicates a time of a predetermined position in a stream of the physical layer frame.
