Abstract:
1. A transmitting apparatus which transmits digital multimedia broadcasting data, comprising: an audio encoder which is configured to encode a basic audio signal and a multichannel audio signal to generate a basic audio stream and a multichannel audio stream; a data stream processor which is configured to generate a first data stream describing property and position data of the basic audio stream and a second data stream describing property and position data of the multichannel audio stream; and a transmitter which is configured to packetizes packetize, multiplexes multiplex and transmit the basic audio stream, the multichannel audio stream, the first data stream, and the second data stream, wherein the first data stream comprises a first elementary stream descriptor (ESD) regarding the basic audio stream and the second data stream comprises a second ESD regarding the multichannel audio stream, wherein the first ESD and the second ESD are combined with each other to generate one object descriptor regarding a single audio object, and wherein the audio encoder, the data stream processor, and the transmitter are implemented using a physical processor and memory.
