Abstract:
[Object] To appropriately control simultaneous presentation of broadcast content and an application.[Solving Means] The information processing apparatus includes: a broadcast content processor configured to receive and process broadcast content; and a controller configured to obtain an application information table, the application information table (XML-AIT) storing an application identification descriptor 24 as information specifying broadcast content, the broadcast content being capable of being presented with the application simultaneously, and to determine if it is possible to present the application and the broadcast content simultaneously or not.
Abstract:
Disclosed herein is a reproduction apparatus including: a reproduction control information acquisition block configured to acquire reproduction control information for controlling reproduction of content; a reproduction block configured to reproduce, in accordance with the acquired reproduction control information, the content that is distributed; and a control block configured to control an operation of an application program that is executed in operative connection with the content being reproduced in accordance with information associated with the application program and obtained from the acquired reproduction control information.
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.
Abstract:
The present disclosure relates to a receiving device, a receiving method, a broadcasting device, a broadcasting method, a program, and a link application control system allowing control of receiving device control functions of a link app on the broadcasting side.A link application control system according to a third aspect of the present disclosure includes the broadcasting device that has a supply unit for supplying to the receiving device application control information concerning a link application executable with reception of the contents by the receiving device, and the receiving device that has an application executing unit for executing a link application that may refer to an image of the received contents and change a layout of a screen, and an application control unit for controlling the application executing unit based on the application control information to limit an action of the link application. The present disclosure is applicable to a television broadcasting system.
Abstract:
[Object] When two image streams to be synchronized and reproduced are separately transmitted by broadcasting and by the Internet, to successfully synchronize and reproduce the two image streams.[Solving Means] A receiver apparatus includes: a broadcast receiver capable of receiving one of a plurality of images as a broadcast stream via broadcasting, a time reference value being added to the plurality of images, the plurality of images being to be synchronized and reproduced; a communication receiver capable of receiving the other of the plurality of images as a communication stream via a network; a criterion time generator configured to generate criterion time based on the time reference value of the broadcast stream, the criterion time being used to generate timing to present the plurality of images; and an adjuster configured to adjust the criterion time based on an amount of delay of the time reference value of the communication stream behind the criterion time.
Abstract:
[Object] To stably supply an application processed together with broadcast content.[Solving Means] An information processing apparatus includes a broadcast content processing unit that receives and processes broadcast content, and a controller that acquires, for each request for acquiring an application capable of being processed together with the broadcast content from a server, an application information table in which first information for calculating a random timing is stored, and calculates, based on the first information, a timing at which the request for acquiring the application is transmitted.
Abstract:
Object To improve a quality of a service that uses an application that uses a broadcast resource.Solving Means There is provided an information processing apparatus including: a broadcast processing unit that receives and processes a broadcast resource constituted of a plurality of types of media information; and a controller that acquires an application information table which stores information requisite for activating an application that can use the broadcast resource and first definition information for specifying the type of the media information of the broadcast resource usable by the application, and judges whether the broadcast resource can be used by the application in a unit of the media information.
Abstract:
Disclosed herein is a receiver including: a reception section adapted to receive AV, namely audio and visual content; a registration section adapted to register related content relating to the AV content based on control information included in an application program executed in response to the AV content; and a presentation control unit adapted to exercise control in such a manner that if the registered related content is selected, the selected related content is presented.
Abstract:
A reception apparatus is provided that includes circuitry configured to receive a digital data stream. The circuitry is configured to acquire closed caption information included in the digital data stream. The circuitry is configured to acquire control information including selection information indicating a selection of a specific mode from a plurality of modes for specifying when closed caption text is to be displayed. The circuitry is further configured to output the closed caption text included in the closed caption information for display to a user, at a display time according to the specific mode, based on the selection information included in the control information.
Abstract:
Provided are an apparatus and a method that are capable of performing reliable display control with no caption display interruption of the TTML caption data. Specifically, when a set value of the caption display end time specification attribute of the TTML caption data is the continuous display instruction value, memory storing and display processing of caption data currently displayed are continued even after reproduction end timing of an image file, and switching processing of TTML caption data files is performed. When a set value of the caption display start time specification attribute of the TTML caption data is the continuous display instruction value, whether or not there is a text string, display processing of the text string is continued, is determined, and when there is the text string, the displayed text is continuously displayed. With the processing, it is possible to achieve display control with no caption display interruption of the TTML caption data.
