Abstract

User adaptive 3D video rendering is disclosed. Content may be displayed on a display. A user's position relative to the display and/or a user's direction of view relative to the display may be determined. A user interface of the content may be adjusted based on the user's position and/or the user's direction of view. Adjusting a user interface may include adjusting the perspective of a view of the content displayed on the display. Adjusting a perspective of the view may include determining an adjusted view of the content from available views based on the user's position and/or the user's direction of view. The available views of the content may be requested from a server. A subset of the available views may be received from the server, for example, based on the user's position and/or the user's direction of view. The adjusted view may be displayed on the display.

First claim

1 . A method for rendering video content, the method comprising:
determining, at a first device, view data; determining, at the first device, an identifier associated with a first view corresponding to the view data; transmitting, from the first device to a view server, a request for the first view, wherein the request for the first view comprises the identifier associated with the first view; receiving, at the first device, the first view; and rendering, at the first device, the first view.

2 . The method of claim 1 , wherein the view data comprises at least one of a viewer's viewpoint, user input, or a viewer's position.

3 . The method of claim 1 , wherein the first view is an interpolated view.

4 . The method of claim 3 , wherein the first view is interpolated based on a plurality of other views.

5 . The method of claim 1 , wherein the first view comprises a plurality of views.

6 . The method of claim 1 , wherein the request for the first view comprises at least a subset of the view data.

7 . The method of claim 1 , further comprising storing the first view in a buffer.

8 . A wireless transmit/receive unit (WTRU) comprising:
a processor configured to:
determine view data;
determine an identifier associated with a first view corresponding to the view data; and
render the first view on a display;
a transmitter configured to transmit a request for the first view to a remote device, wherein the request for the first view comprises the identifier associated with the first view; and a receiver configured to receive the first view.

9 . The WTRU of claim 8 , wherein the first view comprises a plurality of views.

10 . The WTRU of claim 8 , wherein the request for the first view comprises the view data.

11 . The WTRU of claim 10 , wherein the view data comprises at least one of a viewer's viewpoint, user input, or a viewer's position.

12 . The WTRU of claim 8 , wherein the processor is further configured to interpolate a second view based on the first view and a third view.

13 . The WTRU of claim 8 , wherein the processor is further configured to interpolate a second view based on the view data.

14 . The WTRU of claim 8 , wherein the processor is further configured to interpolate a second view based on the first view.

15 . A method for rendering video content, the method comprising:
determining at a first device, view data: determining at the first device, an identifier associated with a first view corresponding to the view data; transmitting, from the first device to a view server, a request for a first view, wherein the request for the first view comprises the identifier associated with the first view; receiving, at the first device from the view server, the first view; interpolating, at the first device, a second view based on the first view; and rendering, at the first device, the second view on a display.

16 . The method of claim 15 , wherein the first view comprises a plurality of views.

17 . The method of claim 15 , wherein the request for the first view comprises the view data.

18 . The method of claim 17 , wherein the view data comprises at least one of a viewer's viewpoint, user input, or a viewer's position.

19 . The method of claim 15 , wherein interpolating the second view based on the first view comprises interpolating the second view based on the first view and a third view.

20 . The method of claim 15 , wherein the processor is further configured to interpolate the second view based on the view data.
