Abstract:
The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method and more particularly to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which bearers transmitted by a plurality of transmission systems are selected appropriately. The reception apparatus acquires control information including information for acquiring data transmitted through a in a first transmission system at a first layer in a protocol stack of an IP (Internet Protocol) transmission system and for identifying a bearer that transmits the data in a second transmission system at a second layer lower than the first layer; and controls an operation of each unit that acquires the data transmitted on the bearer on the basis of the control information. The present technology is applicable to a television receiver corresponding to ATSC3.0, for example.
Abstract:
The present technology relates to a reception device, a transmission device, and a data processing method that enable a flexible operation of a service using an application that accompanies content.A reception device includes: a reception unit that receives content; an acquisition unit that acquires an application in accordance with acquisition source information indicating an acquisition source of the application accompanying the content, the acquisition source information being included in control information transmitted together with the content; and a control unit that instantly starts the acquired application. The present technology can be applied to a television set capable of receiving digital broadcasts, for example.
Abstract:
The present technology relates to a reception apparatus, a transmission apparatus, and a data processing method that permit sharing of a resource that is reused among a plurality of services.The reception apparatus receives content and controls, on the basis of control information that is transported together with the content and that includes resource sharing information indicating whether a resource of the content is shared among a plurality of services, storage of the resource in a storage apparatus such that the resource is shared among the plurality of services. The present technology is applicable, for example, to a television receiver that supports ATSC 3.0.
Abstract:
A transmission apparatus that includes circuitry configured to generate transport protocol selection information used for selecting a transport protocol to be used in a specific service from a plurality of transport protocols conforming to a predetermined standard; and transmit, together with the transport protocol selection information, a content provided by the specific service according to the transport protocol set in the transport protocol selection information, and the plurality of transport protocols include at least ROUTE (Real-Time Object Delivery over Unidirectional Transport) and MMT (MPEG Media Transport).
Abstract:
The present technology relates to a receiving device, a receiving method, a transmitting device, and a transmitting method that enable operation of subtitles to be displayed in a superimposed manner on broadcast content reliably.The receiving device acquires trigger information for providing a function relating to subtitles, the trigger information including location information by which a resource on the Internet is identifiable; acquires subtitle information including a document relating to subtitles described in a predetermined computer language, on the basis of the location information included in the trigger information; and controls displaying of the subtitles on the basis of at least one of the trigger information and the subtitle information. The present technology is applicable to a television receiver capable of receiving digital broadcast signals, for example.
Abstract:
The present technology relates to a reception device, a reception method, a transmission device, and a transmission method for enabling signaling information required for a content reception/reproduction processing to be efficiently distributed.There is provided a reception device including a signaling template acquisition unit for acquiring a LLS signaling template in order to generate LLS signaling information transmitted in LLS and a SCS signaling template in order to generate SCS signaling information transmitted in SCS, a differential information acquisition unit for acquiring LLS differential information applied to the LLS signaling template to generate the LLS signaling information, and SCS differential information applied to the SCS signaling template to generate the SCS signaling information, and a signaling information generation unit for applying the LLS differential information to the LLS signaling template thereby to generate the LLS signaling information, and applying the SCS differential information to the SCS signaling template thereby to generate the SCS signaling information.
Abstract:
The present technology relates to a receiving device, a reception method, a transmitting device, and a transmission method capable of performing an effective filtering process. There is provided a receiving device including a filtering processing unit that performs a filtering process of a packet by using filtering information arranged in a header of the packet transmitted in a first layer that is a layer upper than an IP layer in layers of a protocol of the IP transmission system in a broadcasting wave of digital broadcasting using an IP transmission system. The present technology, for example, can be applied to a television set.
Abstract:
The present disclosure relates to a content supply apparatus, a content supply method, a program, a terminal apparatus, and a content supply system that are capable of describing attribute information of each file stored in a packet transmitted by FLUTE session in other than an FDT.A content supply apparatus of the present disclosure includes: a fragmented stream generation unit that generates a fragmented stream on the basis of source data of content; a FLUTE stream generation unit that generates a FLUTE stream including ALC packets in which the generated fragmented stream is divided and stored, and describes attribute information on the fragmented stream in each of the ALC packets in which the fragmented stream is divided and stored; and a multicast distribution unit that distributes the FLUTE stream by FLUTE multicast. The present disclosure can be applied to a system in which content is distributed by FLUTE multicast.
Abstract:
[Object] To provide an information processing device in which maintenance is enabled by avoiding an increase in an amount of the meta information when a device is remotely controlled by a client using the ABS technique.[Solution] Provided is an information processing device including: a storage unit configured to store a predetermined definition for adding a parameter to access information for accessing each of a plurality of subsegments constituting each piece of encoded data obtained by encoding same content at a different bit rate, or for accessing every element to be acquired through a request to a server described in an MPD; and a communication unit configured to access an address defined in the access information by designating a parameter based on the predetermined definition stored in the storage unit. The address defined in the access information is an address for controlling a device which images the content.
Abstract:
Disclosed herein is a transmission apparatus for distributing a content to a client, including: a question generation section configured to generate question information representative of a question regarding liking of a user of the client; and a transmission section configured to transmit the question information and provider side answer information in the form of a bit string representative of an answer set by a provider which provides the content to the question regarding the liking of the user to the client.
