Abstract:
A reception apparatus includes a receiver and circuitry. The circuitry receives audio/video content and acquires first control information that identifies application control information to control operation of an application run in conjunction with the audio/video content. The circuitry acquires a first table in which the application control information identified by the first control information is stored. The first table includes a time associated with a specific segment of the audio/video content. The circuitry acquires a second table in which application control information identified by second control information is stored. The second table includes a newer version of the first table and the time associated with the specific segment of the audio/video content and included in the first table. The circuitry controls the operation of the application in response to the application control information that is identified by the second control information and stored in the second table.
Abstract:
There is provided an information processing apparatus including a broadcast receiving unit and a controller. The broadcast receiving unit is configured to be capable of receiving a broadcast. The controller is configured to acquire a first application information table by communication, the first application information table storing at least first usage permission information indicating a usage permission range of a resource of the broadcast by an application using the resource, to control an operation of the application, and to acquire a second application information table storing at least second usage permission information indicating the usage permission range of the resource by the application by using the broadcast receiving unit during execution of the application, to control the operation of the application.
Abstract:
Suppression of the data amount of a transmission media stream and reduction of bandwidth consumption are achieved.A transmission side transmits a transmission media stream to a reception side through a predetermined transmission line, the transmission media stream being obtained by multiplexing on a time division basis a first transmission packet containing transmission media in a payload and a second transmission packet containing information on the transmission media in a payload. In this case, reference information is inserted into an insertion area for presentation control information of the transmission media, the reference information being for acquiring the presentation control information, the insertion area being provided in the payload of the second transmission packet. A reception side acquires the presentation control information based on the reference information and performs presentation control of the transmission media.
Abstract:
It is possible to access a presentation control information (HTML document) element contained in a transport media stream from an HTML application side.A first HTML document for displaying a web page is received. In addition, the transport media stream which contains a predetermined number of transport media and a second HTML document as the presentation control information of the transport media is received. A DOM tree of the first HTML document is generated. When a video element that references the transport media stream is present in the first HTML document, the DOM tree that is generated according to the second HTML document contained in the transport media stream is linked beneath a node of the video element.
Abstract:
Disclosed herein is a transmission apparatus for transmitting AV (Audio/Video) content, including: an acquirer configured to acquire an estimated number of audience terminals indicative of an estimated number of reception apparatuses receiving the AV content; a computer configured, in conjugation with the AV content, to compute, on the basis of the estimated number of audience terminals, a validity probability of trigger information associated with control of an application program to be executed in the reception apparatus; a generator configured to generate the trigger signal including the computed validity probability; and a transmitter configured to transmit the generated trigger information with the AV content.
Abstract:
There is provided a display device including a detection section which detects a presence of another display device, and acquires information of a provision source of a function provided by the another display device, a function execution section which executes the function provided by the another display device based on the information acquired from the another display device, a communication section which establishes a connection with the another display device by the execution of the function by the function execution section, and a display section which displays information corresponding to reception, by the communication section, of information of a content provision source specified from content displayed on the another display device with which a connection has been established by the communication section.
Abstract:
Disclosed herein is a reception apparatus including: a reception portion configured to receive AV content; a trigger acquisition portion configured to acquire trigger information for operating an application program to be executed in interlocked relation to the AV content; a table acquisition portion configured to acquire a correspondence table associating a command for controlling the operation of the application program with a valid time of the command; and a control portion configured such that when the time acquired from the trigger information as indicative of the progress of the AV content satisfies a predetermined condition of validity in reference to the valid time of the command on the basis of the acquired correspondence table, the control portion controls the operation of the application program in accordance with the command being valid.
