Abstract: A method is provided for transmitting a broadcast signal in a transmitting system. Audio data of a broadcast service is generated. An audio frame coded by an Audio Compression-4 (AC-4) scheme is generated. The audio frame includes configuration information on the audio frame and at least one substream including the audio data and metadata for the audio data. The configuration information includes substream index information and substream size information. Real time Object delivery over Unidirectional Transport (ROUTE) packets containing the audio frame are generated. The ROUTE packets are processed to generate Internet Protocol (IP) packets. The IP packets are processed to generate link layer packets, and the broadcast signal including at least one data pipe that includes the link layer packets is transmitted.

Abstract: A method to receive a broadcast includes parsing a first trigger for obtaining a first identifier for identifying a targeted Triggered Declarative Object (TDO), and a preparation trigger time for the targeted TDO; parsing a second trigger for obtaining an activation time and a termination time for the targeted TDO; activating the targeted TDO corresponding to the first identifier on a background, when a receiving time of the preparation trigger is before the preparation trigger time, immediately activating the targeted TDO corresponding to the first identifier on the background, when the receiving time of the preparation trigger is after the preparation trigger time; changing a state of the targeted TDO to a foreground, when a current system time is after the activation time; and terminating the targeted TDO, when the current system time is after the termination time.
