Abstract: A method of a reception apparatus for receiving transmission frames. The method includes receiving, by circuitry of the reception apparatus, the transmission frames transmitted on one millisecond boundaries. Each of the transmission frames includes a bootstrap, a preamble, and a payload. The method further includes determining, by the circuitry, an absolute point of time at a predetermined position in a stream of the transmission frames based on first time information included in a first one of the transmission frames.

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.

Abstract: A method is provided for a reception apparatus to store non-real-time (NRT) content. The method includes receiving, by the reception apparatus, the NRT content included in a digital television broadcast signal broadcast from a content source. The received NRT content, included in the digital television broadcast signal broadcast from the content source, is stored in a memory of the reception apparatus. The reception apparatus outputs the NRT content stored in the memory for presentation to a user. The reception apparatus receives a request to store the NRT content in an external device and, in response, sends an instruction via a communication network to store the NRT content in the external device.
