The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method that make it possible to provide a broadcasting service by using MPEG-DASH. Provided is a reception apparatus including a control unit that performs, on the basis of a relationship among a plurality of elements which is prescribed in advance in an MPD conforming to a standard of MPEG-DASH which is transmitted via a broadcast wave or a communication network of digital broadcasting, and a first element for grouping of target elements in a specific layer in which selection or structuring of a component having a structure including a plurality of layers for the selection and the structuring is performed, at least one of the selection and the structuring of the component, and controls reproduction of a content constituted of one or more components. The present technology can be applied to a television receiver, for example.

The present technology relates to an information processing apparatus, an information processing method, and an information processing system capable of achieving appropriate load balancing in a case where a plurality of proxies is installed. The information processing apparatus functions as a proxy that receives a content stream distributed for each of a plurality of services and transmits the content stream to a client device connected to a network, the proxy being configured to function as a master proxy for a slave proxy, and determines a service coverage range corresponding to a predetermined policy, for each of the proxies, making it possible to achieve appropriate load balancing in a case where a plurality of proxies is installed. The present technology can be applied to, for example, an FW proxy device connected to the network such as a home LAN, a head end of a cable operator, and a base station of a mobile network.

A reception apparatus includes receiver circuitry configured to receive a digital broadcast signal and processing circuitry. The processing circuitry is configured to acquire a first application that handles acquisition of content reproduced in non-realtime, the first application acquired on the basis of first signaling data included in the digital broadcast signal. The processing circuitry is further configured to acquire metadata, which includes information for controlling the content acquisition in response to operation of the first application, the metadata included in the digital broadcast signal. The processing circuitry is further configured to control acquisition of the content reproduced in non-realtime by controlling the operation of the first application on the basis of the metadata.

A transmission apparatus and method, respectively, mapping payload data of mapping input data streams onto a mapping output data stream having a channel bandwidth for transmission in a multi-carrier broadcast system. To enable selection of robustness for transmission of data, the apparatus includes a frame forming mechanism mapping data blocks of at least two mapping input data streams onto frames of the mapping output data stream covering the channel bandwidth, each frame including a payload portion, the payload portion including plural data symbols and being segmented into data segments each covering a bandwidth portion of the channel bandwidth. The frame forming mechanism is configured to map the data blocks of the at least two mapping input data streams onto data symbols of the payload portion and includes a MIMO mode selector selecting a MIMO mode of the data blocks per data segment and/or per mapping input data stream.

The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes. In group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 9/15 is interleaved in a unit of a bit group of 360 bits. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence. The present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.

A receiving apparatus is provided. The receiving apparatus includes circuitry configured to receive reference time information and metadata including information for executing processing related to the reference time information. The circuitry is configured to execute processing related to the reference time information based on the metadata. The metadata includes a first offset value between the reference time information and a discontinuous time, a second offset value between the discontinuous time and a local time, and a date and time at which a change in a daylight savings time (DST) status is to occur. The local time is determined based on the reference time information and the metadata.

An object of the present invention is to provide a light source lens that makes it possible to improve unevenness in a luminance distribution, an illumination unit, and a display unit. A light source lens ( 1 ) according to the present disclosure includes an incident surface on which light from a light-emitting device is incident, and an exit surface ( 20 ) that has a diffusing function at a center part ( 21 ) for light incident through the incident surface as well as a light-condensing function at at least a portion of an intermediate part ( 22 ) and a peripheral part ( 23 ) for the light incident through the incident surface.

The present technology relates to a reception apparatus, a transmission apparatus, and a data processing method capable of providing content according to preferences of an end user. The reception apparatus provides content according to the preferences of an end user by processing question information, which indicates a question about the preferences of the end user and is delivered together with content, on the basis of at least one of delivery information indicating that a service for providing dynamic metadata expressing the preferences of the end user is delivered or reference information indicating a reference destination of an application for generating first answer information indicating an answer set by the end user for the question about the preferences of the end user. The present technology can be applied to, for example, a television receiver.

The present technology relates to a data processing device and a data processing method so that an LDPC code with a good bit error rate is provided. An LDPC encoder encodes by an LDPC code whose code length is 16200 bits and code rate is 8/15. The LDPC code includes information bits and parity bits. A parity check matrix H includes an information matrix part corresponding to the information bits of the LDPC code and a parity matrix part corresponding to the parity bits. The information matrix part of the parity check matrix H is represented by a parity check matrix initial value table that indicates a position of an element 1 of the information matrix part for each 360 columns. The present technology is applicable to a case in which LDPC encoding and LDPC decoding are performed.

An association with a system timing at the time of transmission is secured without changing a display timing in text information of a subtitle, and a reception side displays the subtitle at an appropriate timing. A packet in which a document of the text information of the subtitle having display timing information is included in a payload is generated and transmitted in synchronization with a sample period. A header of the packet includes a time stamp on a first time axis indicating a start time of the corresponding sample period. The payload of the packet further includes reference time information of a second time axis regarding the display timing associated with the start time of the corresponding sample period.
