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.

3. The receiving apparatus according to claim 2, further comprising:

a table acquisition block configured to acquire a relation table in which a command for controlling an operation of said application program is related with a valid time of said command,

said control block controlling an operation of said application program on the basis of said acquired relation table, if a time indicative of a progression of said audio/video content obtained from said trigger information satisfies a predetermined valid condition relative to said valid time of said command, in accordance with said valid command.

4. The receiving apparatus according to claim 3, further comprising:

an acquisition-destination information acquisition block configured to acquire first acquisition-destination information indicative of an acquisition destination of said relation table and second acquisition-destination information indicative of an acquisition destination of said application program on the basis of said trigger information,

said table acquisition block acquiring said relation table on the basis of said first acquisition-destination information and said application acquisition block acquiring said application program on the basis of said second acquisition-destination information.

5. The receiving apparatus according to claim 4, wherein said second acquisition-destination information has any one of a same configuration as that of an NRT-IT (Non-Real Time-Information Table) for use in transmitting NRT content of an NRT service by said broadcast wave and a configuration corresponding to that of the NRT, said second acquisition-destination information being provided from an information processing apparatus connected to said Internet.

6. The receiving apparatus according to claim 1, wherein said trigger information is transmitted by said broadcast wave, and

said trigger acquisition block acquires said trigger information transmitted by said broadcast wave.

7. The receiving apparatus according to claim 6, wherein said control block controls an operation of said application program acquired in accordance with a command included in said trigger information acquired from said broadcast wave.

8. The receiving apparatus according to claim 7, wherein said application program is transmitted as NRT content of an NRT service by use of a FLUTE (File Delivery over Unidirectional Transport) session, and

said application acquisition block references an FDT (File Delivery Table) identified by an SMT (Service Map Table) and an NRT-IT on the basis of identification information of said NRT service included in said trigger information and said NRT content, thereby acquiring said application program transmitted by a FLUTE session.

9. The receiving apparatus according to claim 8, wherein, if said application program transmitted by a FLUTE session cannot be acquired, said application acquisition block acquires said application program on the basis of third acquisition-destination information indicative of an acquisition destination of said application program distributed by said Internet written to said NRT-IT.

10. The receiving apparatus according to claim 3, further comprising:

an acquisition-destination information acquisition block configured to acquire second acquisition-destination information indicative of an acquisition destination of said application program on the basis of said relation table,

said table acquisition block acquiring said relation table on the basis of first acquisition-destination information indicative of an acquisition destination of said relation table obtained from said trigger information,

said application acquisition block acquiring said application program on the basis of said second acquisition-destination information.

11. The receiving apparatus according to claim 10, wherein said control block checks if said receiving apparatus has a performance necessary for operating said application program acquired on the basis of said acquired relation table, and
