Abstract

Disclosed is a hybrid delivery method for content in which content is divided corresponding to the number of means of delivery and transmitted. An hybrid delivery method of content comprises the steps of: detecting the number of delivery means by which a server can transmit content to a client; dividing the content so as to correspond to the detected number of delivery means; generating composition information for each of the divided content; and transmitting the divided content and the composition information to the client using the transmission means. Thus, a variety of transmission means can be used effectively.

First claim

What is claimed is:

1. A method for delivering content, the method comprising:
fragmenting content;
generating composition information for pieces of fragmented content; and
delivering the pieces of fragmented content to a client using delivery means,
wherein the pieces of fragmented content are encapsulated into Moving Picture Experts Group Media Transport (MMT) package including at least one MMT asset the composition information (CI), and transport characteristics (TC),
wherein the MMT asset is a logical data group of at least one media processing unit (MPU) sharing same asset identifier (asset ID), the MPU having an independently consumed format generated by encapsulating media fragment unit (MFU), the MFU being data processed by a media decoder,
wherein the composition information comprises information on a spatial and temporal relationship among the MMT assets,
wherein the composition information is configured based on an Hypertext Markup Language fifth version (HTML5) document,
wherein the composition information represents attributes of media elements related to the spatial and temporal relationship among the MMT assets by referencing corresponding attributes in the HTML5 document.

2. The method of claim 1 , further comprising detecting, by a server, the number of delivery means through which the server is able to transmit the content to the client, wherein the number of fragmented content corresponds to the number of detected delivery means.

3. The method of claim 1 , wherein the content comprises at least one of a sub-stream, an MMT asset, an MMT package, an MPU, an MFU, and an MMT packet.

4. The method of claim 1 , wherein the composition information is included in at least one of package information of an MMT package, a header of an MMT packet, and a payload.

5. The method of claim 1 , wherein all the pieces of fragmented content form a single MMT package.

6. The method of claim 1 , wherein each of the pieces of fragmented content forms a single MMT package.

7. The method of claim 1 , wherein the delivering the pieces of fragmented content comprises sending the pieces of fragmented content and the composition information to the client if the composition information is present outside the pieces of fragmented content.

8. The method of claim 1 , wherein the MMT assets in the MMT package are transmitted through different transport means, wherein a local composition information describes relationship among the MMT assets in each transport means, wherein the composition information comprises information on relationship between the local composition information.

9. The method of claim 1 , wherein a single MMT package is transmitted through different transport means, wherein the single MMT package comprises a local composition information describing relationship among MMT assets in each transport means, wherein the composition information comprises information on relationship between the local composition information.

10. The method of claim 1 , wherein each of the pieces of fragmented content is transmitted through different transport means, wherein each of the pieces of fragmented content comprises a local composition information describing relationship among MMT assets in each transport means, wherein the composition information comprises information on relationship between the local composition information.

11. A method for receiving content, comprising:
receiving pieces of fragmented content from a server; and
aggregating the pieces of fragmented content based on composition information included in the pieces of fragmented contend,
wherein the pieces of fragmented content are encapsulated into Moving Picture Experts Group Media Transport (MMT) package including at least one MMT asset, the composition information (CI), and transport characteristics (TC),
wherein the MMT asset is a logical data group of at least one media processing unit (MPU) sharing same asset identifier (asset ID), the MPU having an independently consumed format generated by encapsulating media fragment unit (MFU), the MFU being data processed by a media decoder,
wherein the composition information comprises information on a spatial and temporal relationship among the MMT assets,
wherein the composition information is configured based on an Hypertext Markup Language fifth version (HTML5) document,
wherein the composition information represents attributes of media elements related to the spatial and temporal relationship among the MMT assets by referencing corresponding attributes in the HTML5 document.

12. The method of claim 11 , wherein the receiving the pieces of fragmented content comprises receiving the pieces of fragmented content and the composition information from the server if the composition information is present outside the pieces of fragmented content.

13. A hybrid delivery apparatus for delivering content comprising: a processor that executes a program code stored in a non-transitory computer-readable medium, wherein the computer program code includes instructions to:
fragmenting content;
generate composition information for pieces of fragmented content; and
deliver the pieces of fragmented content to a client using delivery means,
wherein the pieces of fragmented content are encapsulated into Moving Picture Experts Group Media Transport (MMT) package including at least one MMT asset the composition information (CI), and transport characteristics (TC),
wherein the MMT asset is a logical data group of at least one media processing unit (MPU) sharing same asset identifier (asset ID), the MPU having an independently consumed format generated by encapsulating media fragment unit (MFU), the MFU being data processed by a media decoder,
wherein the composition information comprises information on a spatial and temporal relationship among the MMT assets,
wherein the composition information is configured based on an Hypertext Markup Language fifth version (HTML5) document,
wherein the composition information represents attributes of media elements related to the spatial and temporal relationship among the MMT assets by referencing corresponding attributes in the HTML5 document.

14. The apparatus of claim 13 , wherein the computer program code further includes instruction to detect the number of pieces of delivery means transmitting the content to the client,
wherein the number of fragmented content corresponds to the number of detected delivery means.

15. The apparatus of claim 13 , wherein the content comprises at least one of a sub-stream, an MMT asset, an MMT package, an MPU, an MFU, and an MMT packet.

16. The apparatus of claim 13 , wherein the composition information is included in at least one of package information of an MMT package, a header of an MMT packet, and a payload.

17. The apparatus of claim 13 , wherein all the pieces of fragmented content form a single MMT package.

18. The method of claim 13 , wherein each of the pieces of fragmented content forms a single MMT package.

19. The apparatus of claim 13 , wherein the computer program code further includes instruction to deliver the pieces of fragmented content and the composition information to the client if the composition information is present outside the pieces of fragmented content.

20. An apparatus for receiving content comprising a processor that executes a program code stored in a non-transitory computer-readable medium, wherein the computer program code includes instructions to:
receive pieces of fragmented content from a server; and
aggr
