Abstract

The present invention relates to a system for transmitting and receiving audio, particularly, to a method and apparatus for transmitting and receiving of object-based audio contents, which packetizes audio objects having the same characteristic. To achieve the above, the present invention includes filtering a plurality of ESs according to common information, adding a packet header to the respective filtered ESs and generate ES packets, aggregating all the generated ES packets and then adding a multi-object packet header to the aggregated ES packets to generate an object packet, and multiplexing the generated object packet, packetizing the multiplexed object packet according to a transmitting media and transmitting the packetized object packet.

First claim

The invention claimed is:

1. A method of transmitting object-based digital audio contents comprising:
receiving a plurality of elementary streams related to the audio data;
filtering the plurality of elementary streams based on common information associated with the element streams;
generating a packet including the filtered elementary streams
transmitting the packet and the common information,
wherein the common information includes at least one of an entire length of the packet, and a same encoding method related to the elementary streams, and replay time information related to the elementary streams,
wherein the packets comprises three-dimensional (3D) information of the audio data, wherein the 3D information comprises a space arrangement information or size information of the respective audio data.

2. A method of receiving object-based digital audio contents comprising:
depacketizing an packet including the elementary streams of audio data filtered based on common information;
reproducing the elementary streams of the audio data based on the common information,
wherein the common information includes at least one of an entire length of the packet, and a same encoding method related to the elementary streams, and replay time information related to the elementary streams,
wherein the packets comprises three-dimensional (3D) information of the audio data, wherein the 3D information comprises a space arrangement information or size information of the respective audio data.

3. The method of claim 2 , wherein the reproducing comprising:
adding a 3D scene based on the 3D information into the audio data.

4. An Apparatus for transmitting object-based digital audio contents comprising:
a processor configured to:
receive a plurality of elementary streams related to the audio data;
filter the plurality of elementary streams based on common information associated with the element streams;
generate a packet including the filtered elementary;
transmit the packet and the common information,
wherein the common information includes at least one of an entire length of the packet, and a same encoding method related to the elementary streams, and replay time information related to the elementary streams,
wherein the packets comprises three-dimensional (3D) information of the audio data, wherein the 3D information comprises a space arrangement information or size information of the respective audio data.

5. An apparatus for receiving object-based digital audio contents comprising:
a processor configured to:
depacketize an packet including the elementary streams of audio data filtered based on common information;
reproduce the elementay streams of the audio data based on the common information,
wherein the common information includes at least one of an entire length of the packet, and a same encoding method related to the elementary streams, and replay time information related to the elementary streams,
wherein the packets comprises three-dimensional (3D) information of the audio data, wherein the 3D information comprises a space arrangement information or size information of the respective audio data.

6. The method of claim 1 , wherein the space arrangement information of the 3D information of the audio data corresponds to X, Y, and Z coordinate axes.

7. The method of claim 2 , wherein the space arrangement information of the 3D information of the audio data corresponds to X, Y, and Z coordinate axes.

8. The method of claim 4 , wherein the space arrangement information of the 3D information of the audio data corresponds to X, Y, and Z coordinate axes.

9. The method of claim 5 , wherein the space arrangement information of the 3D information of the audio data corresponds to X, Y, and Z coordinate axes.
