    摘要： The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which an increase in data size of signaling information transmitted by broadcasting can be suppressed. Provided is a reception apparatus including: a reception unit that receives a broadcast wave of digital broadcasting using an IP (Internet Protocol) transmission system; and a control unit that controls, on the basis of information for managing only a broadcast component transmitted by a broadcast wave of the digital broadcasting, which is first signaling information transmitted by a broadcast wave of the digital broadcasting, or information for managing at least one component of the broadcast component and a communication component transmitted by communication, which is second signaling information transmitted by communication, operations of respective units for acquiring the at least one component of the broadcast component and the communication component. The present technology is applicable to a television receiver, for example.

    摘要： A configuration is realized such that a playback application applied in a receiving device can be determined using a service category identifier recorded in an SLT that can be received in advance. The service category identifier capable of identifying an application applied to a provided service such as a program provided by a transmitting device is transmitted to the receiving device. The receiving device performs a continuation process on an application applied before service transition when the service transition occurs and when applications applied to services before and after the transition are same. The service category identifier is an identifier capable of identifying the service by determining whether to apply a residential playback application or a broadcast playback application for playback of the service.

    摘要： The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which channel selection information can be acquired more efficiently. Provided is a reception apparatus, including: a reception unit that receives a broadcast wave of digital broadcasting using an IP (Internet Protocol) transmission system; a communication unit that receives first signaling information for acquiring broadcast content transmitted by the broadcast wave through communication with a server via a network; an acquisition unit that acquires, on the basis of the first signaling information, a physical parameter used in a physical layer in a hierarchy of a protocol of the IP transmission system; and a control unit that controls, on the basis of the physical parameter, operations of respective units that perform channel selection processing. The present technology is applicable to a portable receiver that is movable, for example.

    摘要： The present disclosure relates to a content supply device, a content supply method, a program, and a content supply system, wherein an adaptive streaming technique based on DASH is extended to enable the use of broadcast distribution and multicast distribution.A content supply device according to a first aspect of the present disclosure is a content supply device that supplies streaming data of content in accordance with an adaptive streaming technique, the device including: an HTTP distribution unit that makes the streaming data into a file for each segment and distributes by HTTP the obtained segment file through a bidirectional communication network; a multicast distribution unit that distributes the segment file by multicast; and a meta file generation unit that generates a meta file in which information for receiving the segment file to be subjected to the HTTP distribution or the multicast distribution is described. The present disclosure is applicable to the system for streaming the content.
