Abstract

A data transmitting apparatus is provided. The data transmitting apparatus includes a packet generator configured to generate a packet including a plurality of sub packets and a transmitter configured to transmit the generated packet to a data receiving apparatus. Each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

Claims

1. A data transmitting apparatus, comprising:

a packet generator configured to generate a packet including a plurality of sub packets; and

a transmitter configured to transmit the generated packet to a data receiving apparatus,

wherein each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

2. The data transmitting apparatus as claimed in claim 1, wherein each of the plurality of sub packets includes an identification field which represents whether the corresponding sub packet indicates content among the plurality of contents.

3. The data transmitting apparatus as claimed in claim 1, wherein the generated packet includes a header,

wherein the header includes one of a stream present bit indicating whether or not each of the plurality of sub packets includes the audio data and a stream flat bit indicating whether or not the audio data included in each of the plurality of sub packets is effective data.

4. The data transmitting apparatus as claimed in claim 1, wherein each of the plurality of sub packets stores a portion of the audio data.

5. The data transmitting apparatus as claimed in claim 1, wherein the audio data includes audio signals of two channels or more.

6. The data transmitting apparatus as claimed in claim 1, wherein the audio data complies with an international electrotechnical commission (IEC) 60958 format.

21. The data transmitting apparatus as claimed in claim 1, wherein the audio data comprises multi-stream audio data.

22. The data transmitting apparatus as claimed in claim 1, wherein each type of content among the plurality of contents corresponds to a different view of the plurality of contents.

23. The data transmitting apparatus as claimed in claim 1, wherein each of the different views corresponds to a different view to be displayed during the use of a video game.

24. The data transmitting apparatus as claimed in claim 1, wherein the packet is generated according to one of the Mobile High-Definition Link (MHL) standard or the High-Definition Multimedia Interface (HDMI) standard.

25. The data transmitting apparatus as claimed in claim 1, wherein each sub-packet comprises a part of a 3D audio sample.

26. The data transmitting apparatus as claimed in claim 1, wherein the audio data includes audio signals of 32 channels.

7. A data receiving apparatus, comprising:

a receiver configured to receive a packet including a plurality of sub packets; and

a packet parsing unit configured to perform parsing on the received packet,

wherein each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

8. The data receiving apparatus as claimed in claim 7, wherein the received packet includes a header,

wherein the header includes one of a stream present bit indicating whether or not each of the plurality of sub packets includes the audio data and a stream flat bit indicating whether or not the audio data included in each of the plurality of sub packets is effective data.

9. The data receiving apparatus as claimed in claim 7, wherein each of the plurality of sub packets stores a portion of the audio data.

10. The data receiving apparatus as claimed in claim 7, wherein the audio data includes audio signals of two channels or more.

11. The data receiving apparatus as claimed in claim 7, wherein the audio data complies with an international electrotechnical commission (IEC) 60958 format.

12. A data transreceiving system, comprising:

a data transmitting apparatus configured to generate a packet including a plurality of sub packets and transmit the generated packet; and

a data receiving apparatus configured to receive the transmitted packet and perform parsing on the received packet,

wherein each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

13. A data transmitting method, comprising:

generating a packet including a plurality of sub packets; and

transmitting the generated packet to a data receiving apparatus,

wherein each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

14. The data transmitting method as claimed in claim 13, wherein each of the plurality of sub packets further includes an identification field which represents whether the corresponding sub packet indicates content among the plurality of contents.

15. The data transmitting method as claimed in claim 13, wherein the generated packet includes a header,

wherein the header includes one of a stream present bit indicating whether or not each of the plurality of sub packets includes the audio data and a stream flat bit indicating whether or not the audio data included in each of the plurality of sub packets is effective data.

16. The data transmitting method as claimed in claim 13, wherein each of the plurality of sub packets stores a portion of the audio data.

17. A data receiving method, comprising:

receiving a packet including a plurality of sub packets; and

performing parsing on the received packet,

wherein each of the plurality of sub packets includes audio data corresponding to content among a plurality of contents.

18. The data receiving method as claimed in claim 17, wherein the received packet includes a header,

wherein the header includes one of a stream present bit indicating whether or not each of plurality of sub packets includes the audio data and a stream flat bit indicating whether or not the audio data included in each of the plurality of sub packets is effective data.

19. The data receiving method as claimed in claim 17, wherein each of the plurality of sub packets stores a portion of the audio data.

20. The data receiving apparatus as claimed in claim 17, wherein the audio data includes audio signals of two channels or more.

27. A method of audio data transmission, comprising:

generating a 3D audio stream comprising a plurality of packets, each of the packets corresponding to a plurality of audio channels and comprising a plurality of sub-packets, each of the sub-packets configured to include 3D audio data; and

transmitting the generated 3D audio stream to a receiver.

28. The method as claimed in claim 27, wherein each packet comprises a header indicating which sub-packets in the corresponding packet include the 3D audio data.

29. The method as claimed in claim 28, wherein the header further indicates whether the corresponding packet is fully packetized up to a maximum number of audio channels.

30. The method as claimed in claim 29, wherein the header further indicates whether the corresponding packet is a first packet of a 3D audio sample in the 3D audio stream.
