1. An audio decoding apparatus comprising:
a receiver configured to receive an audio bitstream comprising packets;
a processor configured to:
identify a type of a packet among the packets; and
obtain system data and a type of a system engine which corresponds to the system data from the packet, if the identified type of the packet indicates system meta data; and
a transmitter configured to transmit the packet including the type of the system engine and the system data to the system engine, if the type of the system engine is defined,
wherein the processor is further configured to discard the packet including the type of the system engine and the system data if the type of the system engine is not defined.
