Abstract

Disclosed is a method of encoding three-dimensional (3D) content. The method of encoding 3D content according to an embodiment may include setting a dependency between texture information and depth information of the 3D content, and generating a bitstream comprising the dependency.

Claims

1. A method of adaptive streaming service performed by a server, and the method comprising:

receiving a request for a media content from a client; and

providing the media content based on a media presentation description (MPD),

wherein the MPD includes sequence of at least one period,

wherein the each period includes at least one adaptation set comprising media content component,

wherein the each adaptation set include at least one representation,

wherein the each representation include at least one sub-representation,

wherein the each representation include at least one segment,

wherein the client switch from one representation to another representation to adapt to a network condition.

2. The method of claim 1, wherein the media content is divided into segments over time within the representation.

3. The method of claim 1, wherein the media content component is referred to as a media stream,

wherein the media stream inherit an attribute of media content used for encoding media content.

4. The method of claim 1, wherein the adaptation set is a set of replaceable encoded versions of at least one of media content component.

5. The method of claim 1, wherein the client ignore representation depending on codec or other rendering technologies not supported.

6. The method of claim 1, wherein an element of the media content component including (i) “

Accessibility”

element related to information about an accessibility scheme, (ii) “

Role”

element related to information about a role annotation scheme, (iii) “

Rating”

element related to information about a rating scheme, (iv) “

Viewpoint”

element related to information about a viewpoint annotation scheme.

7. The method of claim 1, wherein an element of the adaptation set comprising:

(i) ContentType attribute which is specified a media content component type of the adaptation set

(ii) par attribute which is specified a picture aspect ratio,

(iii) minBandWidth attribute which is specified a minimum bandwidth attribute value of all representations within the adaptation set,

(iv) maxBandWidth attribute which is specified a maximum bandwidth attribute value of all representations within then adaptation set,

(v) minWidth attribute which is specified a minimum width attribute value of all representations within an adaptation set,

(vi) maxWidth attribute which is specified a maximum width attribute value of all representations within the adaptation set,

(vii) minHeight attribute which is specified a minimum height attribute value of all representations within the adaptation set,

(viii) maxHeight attribute which is specified a maximum height attribute value of all representations within the adaptation set,

(ix) minFrameRate attribute which is specified a minimum frameRate attribute value of all representations within the adaptation set,

(x) maxFrameRate attribute which is specified a maximum frameRate attribute value of all representations within the adaptation set.

8. A server comprising:

one or more processor is configured to;

receive a request for a media content from a client,

provide the media content based on a media presentation description (MPD),

wherein the MPD includes sequence of at least one period,

wherein the each period includes at least one adaptation set comprising media content component,

wherein the each adaptation set include at least one representation,

wherein the each representation include at least one sub-representation,

wherein the each representation include at least one segment,

wherein the client switch from one representation to another representation to adapt to a network condition.

9. The server of claim 8, wherein the media content is divided into segments over time within the representation.

10. The server of claim 8, wherein the media content component is referred to as a media stream,

wherein the media stream inherit an attribute of media content used for encoding media content.

11. The server of claim 8, wherein the adaptation set is a set of replaceable encoded versions of at least one of media content component.

12. The server of claim 8, wherein the client ignore representation depending on codec or other rendering technologies not supported.

13. The server of claim 8, wherein an element of the media content component including (i) “

Accessibility”

element related to information about an accessibility scheme, (ii) “

Role”

element related to information about a role annotation scheme, (iii) “

Rating”

element related to information about a rating scheme, (iv) “

Viewpoint”

element related to information about a viewpoint annotation scheme.

14. The server of claim 8, wherein an element of the adaptation set comprising:

(i) ContentType attribute which is specified a media content component type of the adaptation set

(ii) par attribute which is specified a picture aspect ratio,

(iii) minBandWidth attribute which is specified a minimum bandwidth attribute value of all representations within the adaptation set,

(iv) maxBandWidth attribute which is specified a maximum bandwidth attribute value of all representations within then adaptation set,

(v) minWidth attribute which is specified a minimum width attribute value of all representations within an adaptation set,

(vi) maxWidth attribute which is specified a maximum width attribute value of all representations within the adaptation set,

(vii) minHeight attribute which is specified a minimum height attribute value of all representations within the adaptation set,

(viii) maxHeight attribute which is specified a maximum height attribute value of all representations within the adaptation set,

(ix) minFrameRate attribute which is specified a minimum frameRate attribute value of all representations within the adaptation set,

(x) maxFrameRate attribute which is specified a maximum frameRate attribute value of all representations within the adaptation set.
