Abstract:
Provided are a device and a method capable of efficiently performing a synthesis process of broadcast reception data and network reception data. Broadcast reception data received by a receiving device via a communication unit is set as a media source object corresponding to a processing object of an application executed by the receiving device under an application programming interface (API). The application executes a synthesis process of the broadcast reception data and network reception data received via a network as processing for the media source object. The application obtains a time offset corresponding to a time difference between an application time axis and a broadcast time axis on the basis of an API application process to execute a high-accuracy and low-delay data synthesis process.
Abstract:
The present technology relates to a receiving device, a receiving method, a transmission device, and a transmission method for operation of various services.The receiving device acquires trigger information for providing various functions, the trigger information containing type information indicating the type of trigger information and channel information indicating a series for each function provided by the trigger information. The receiving device performs processing corresponding to each function on the basis of the trigger information identified by the type information and the channel information. The present technology is applicable to a television receiver being able to receive a digital broadcast signal, for example.
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 session 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:
Disclosed herein is an information processing apparatus which cooperates with a terminal apparatus to configure a home network system, including: a frame visual attribute setting section configured to set a frame visual attribute to a window provided on a screen to display a reproduced piece of content; a publication section configured to publish a command adapted to request notification of the frame visual attribute set to the window from the terminal apparatus to the terminal apparatus; and a notification section configured to notify the terminal apparatus of the frame visual attribute of the window in response to calling of the command from the terminal apparatus.
Abstract:
Disclosed herein is a receiving apparatus, a receiving method, and a program which are configured to provide application programs to be executed in response to AV content. The receiving apparatus includes: a receiving block; a trigger acquisition block; an application acquisition block; and a control block. The control block acquires trigger information and, on the basis of a command obtained from the acquired trigger information, acquires a data broadcast application from an application server on the Internet or a data broadcast application transmitted as NRT content of an NRT service using a FLUTE session by referencing an FDT identified by an SMT and an NRT-IT. In accordance with a command obtained from the acquired trigger information, the control block controls an operation of the acquired application program. The present technology is applicable to television receivers configured to receive digital television broadcast signals.
Abstract:
A content supplying apparatus, a content supplying method, a program, a terminal device, and a content supplying system capable of notifying a correspondence relation between a FLUTE stream and a segment stream to a reception side, and applicable to a system distributing a content in the FLUTE multicast manner. The content supplying apparatus includes: a FLUTE stream generating unit that generates a FLUTE stream based on a fragment stream and generates an SDP by describing information relating to an MPD in which information required for the reception side to acquire information relating to a FLUTE session distributing the FLUTE stream and the fragment stream corresponding to the FLUTE stream is described; and a multicast distribution unit that distributes the FLUTE stream and the SDP in a FLUTE multicast manner.
Abstract:
According to one embodiment, a computer-implemented method for a digital broadcast system comprises an operation of receiving and processing an electronic questionnaire from at least one service provider of the digital broadcast system by a receiver. For instance, the electronic questionnaire has a first data structure that, when processed by the receiver, generates for display a plurality of questions. Thereafter, the method comprises an operation of acquiring answers to the electronic questionnaire in the receiver. The answers are used in filtering content subsequently downloaded to the receiver.
Abstract:
Disclosed herein is a transmission apparatus for distributing a content to a client, including a script generation section configured to generate a script for obtaining user side answer information representative of an answer of a user of the client to a question regarding liking of the user, a trigger generation section configured to generate trigger information regarding execution of the script by the client, and a transmission section configured to transmit the trigger information and the script to the client in response to distribution of a first content to the client and transmitting, in response to distribution of a second content different from the first content to the client, provider side answer information representative of an answer set by a provider which provides the first or second content to the question regarding the liking of the user to the client.
Abstract:
Enable appropriate caching of application programs executed in coordination with AV content. The cache memory temporarily stores a coordinated application that is executed in coordination with received AV content. When a plurality of coordinated applications are stored in the cache memory, a control block controls the cache memory according to the priority of the coordinated applications which corresponds to a predetermined frequency specified for each of them in advance. The present technology is applicable to, for example, television receivers that receive digital television broadcast signals.
Abstract:
Disclosed herein is a streaming distributing device including: a content fragment generating section configured to generate a fragment storing data of a content to be distributed by streaming, the fragment being defined by an MP4 file format; and a subtitle fragment generating section configured to generate a fragment storing a TTML (Timed Text Markup Language) document instance relating to a subtitle to be displayed in the content, the fragment being defined by the MP4 file format, wherein the subtitle fragment generating section adds, to header information of the fragment, instance classification distinguishing information for distinguishing whether the TTML document instance stored in the fragment is a TTML document instance specifying a rendering context relating to the subtitle.
