RECEIVING DEVICE, RECEIVING METHOD, PROGRAM, AND INFORMATION-PROCESSING SYSTEM.

摘要

This technology pertains to a receiving device, a receiving method, a program and an information-processing system which are capable of providing an application program that is executed in conjunction with AV content. A trigger extraction unit extracts trigger information that is transmitted along with received AV content, and includes time information for causing a data-broadcasting application to operate at a prescribed time. A TPT analysis unit obtains a command for controlling the operation of the data-broadcasting application, and a TPT associated with the period of validity of the command. A control unit controls the operation of the data-broadcasting application according to the valid command, when the time expressing the progression of the AV content and obtained from the time information included in the extracted trigger information falls within the period of validity of the command, on the basis of the obtained TPT. It is possible to apply this technology to a television receiver for receiving a digital television broadcast signal, for example.
