Abstract

A method and an apparatus of transmitting media content in a multimedia system are provided. The method includes determining a transmission unit for transmitting at least one multimedia source related to the media content, generating a data stream including header information and the at least one multimedia source according to the determined transmission unit, and transmitting the data stream through a communication network.

Claims

1. A method of transmitting a media content in a multimedia system, the method comprising:

determining a transmission unit for transmitting at least one multimedia source related to the media content;

generating a data stream including header information and the at least one multimedia source according to the determined transmission unit; and

transmitting the generated data stream through a communication network.

2. The method as claimed in claim 1, wherein the transmission unit is classified into at least one of a data structure for transmission of real time data and a data structure for transmission of non-real time data.

3. The method as claimed in claim 2, wherein, when the transmission unit is the data structure for the transmission of the real time data, the transmission unit is determined to be one of a Media Fragment Unit (MFU) which is a minimum unit of decodable media data and a Media Unit (MU) which is unit data including additional control information related to the decoding and one or more MFUs.

4. The method as claimed in claim 3, wherein, when the transmission unit is the data structure for the transmission of the non-real time data, the transmission unit is determined to be one of an asset that is unit data including one or more MUs and a package which is unit data configuring a hybrid media content including multiple assets.

5. The method as claimed in claim 3, wherein, when the MFU corresponds to one slice within one frame, and

wherein the one frame corresponds to one MU.

6. The method as claimed in claim 1, wherein, when the transmission unit is a Media Fragment Unit (MFU) which is a minimum unit of decodable media data, the header information contains at least one of information indicating an order that the MFU is to be used, information indicating a priority of the MFU, and count information on subordinate MFUs that are subordinate to the MFU.

7. An apparatus for transmitting a media content in a multimedia system, the apparatus comprising:

a transmission unit for transmitting a data stream through a communication network; and

a controller for determining a transmission unit for transmitting at least one multimedia source related to the media content, for generating a data stream including header information and the at least one multimedia source according to the determined transmission unit, and for controlling transmission of the generated data stream.

8. The apparatus as claimed in claim 7, wherein the transmission unit is classified into at least one of a data structure for transmission of real time data and a data structure for transmission of non-real time data.

9. The apparatus as claimed in claim 8, wherein, when the transmission unit is the data structure for the transmission of the real time data, the transmission unit is determined to be one of a Media Fragment Unit (MFU) which is a minimum unit of decodable media data and a Media Unit (MU) which is unit data including additional control information related to the decoding and one or more MFUs.

10. The apparatus as claimed in claim 9, wherein, when the transmission unit is the data structure for the transmission of the non-real time data, the transmission unit is determined to be one of an asset that is unit data including one or more MUs and a package which is unit data configuring a hybrid media content including multiple assets.

11. The apparatus as claimed in claim 9, wherein, when the MFU corresponds to one slice within one frame, and

wherein the one frame corresponds to one MU.

12. The apparatus as claimed in claim 7, wherein, when the transmission unit is a Media Fragment Unit (MFU) which is a minimum unit of decodable media data, the header information contains at least one of information indicating an order that the MFU is to be used, information indicating a priority of the MFU, and count information on subordinate MFUs that are subordinate to the MFU.

13. A method of receiving a media content in a multimedia system, the method comprising:

receiving a data stream of the media content through a communication network; and

determining a transmission unit of the media content, identifying header information according to the determined transmission unit, and decoding the media content including at least one multimedia source according to the identified header information.

14. The method as claimed in claim 13, wherein the transmission unit is classified into at least one of a data structure for transmission of real time data and a data structure for transmission of non-real time data.

15. The method as claimed in claim 14, wherein, when the transmission unit is the data structure for the transmission of the real time data, the transmission unit is determined to be one of a Media Fragment Unit (MFU) which is a minimum unit of decodable media data and a Media Unit (MU) which is unit data including additional control information related to the decoding and one or more MFUs.

16. The method as claimed in claim 15, wherein, when the transmission unit is the data structure for the transmission of the non-real time data, the transmission unit is determined to be one of an asset that is unit data including one or more MUs and a package which is unit data configuring a hybrid media content including multiple assets.

17. The method as claimed in claim 15, wherein, when the MFU corresponds to one slice within one frame, and

wherein the one frame corresponds to one MU.

18. The method as claimed in claim 13, wherein, when the transmission unit is a Media Fragment Unit (MFU) which is a minimum unit of decodable media data, the header information contains at least one of information indicating an order that the MFU is to be used, information indicating a priority of the MFU, and count information on subordinate MFUs that are subordinate to the MFU.

19. An apparatus for receiving a media content in a multimedia system, the method comprising:

a receiving unit for receiving a data stream of the media content through a communication network; and

a controller for determining a transmission unit of the media content, for identifying header information according to the determined transmission unit, and for decoding the media content including at least one multimedia source according to the identified header information.

20. The apparatus as claimed in claim 19, wherein the transmission unit is classified into at least one of a data structure for transmission of real time data and a data structure for transmission of non-real time data.

21. The apparatus as claimed in claim 20, wherein, when the transmission unit is the data structure for the transmission of the real time data, the transmission unit is determined to be one of a Media Fragment Unit (MFU) which is a minimum unit of decodable media data and a Media Unit (MU) which is unit data including additional control information related to the decoding and one or more MFUs.
