1. An interactive method comprising:
- receiving, at a display device, background video comprising encoded video frames, at least one encoded video frame comprising a plurality of sub-pictures, each of the plurality of sub-pictures comprising a different alternative background representing a possible outcome of an interactive video application;
decoding said at least one encoded video frame to produce a decoded video frame;
upsampling a first sub-picture of the plurality of sub-pictures of said decoded video frame to a first full upsampled video frame and displaying the first full upsampled video frame as a first alternative background;
switching, at the display device, between the first sub-picture of the plurality of sub-pictures and a second sub-picture of the plurality of sub-pictures of said decoded video frame; and
upsampling the second sub-picture to a second full upsampled video frame after the switching and displaying said second full upsampled video frame as a second alternative background instead of the first full upsampled video frame;
displaying a display effect in response to the switching; and
wherein the display effect comprises at least one of the following;
an illusion of an image which is broader than an image displayed before the switching;
an illusion of an image which is higher than the image displayed before the switching;
an illusion of an image which is broader and higher than the image displayed before the switching; and
an illusion of an image which is, with respect to the image displayed before the switching, at least one of the following;
horizontally distorted; and
vertically distorted.

Abstract
An interactive method includes receiving, at a display device, background video including a multiplicity of video frames, at least one of the multiplicity of video frames including a plurality of sub-pictures, each of the plurality of sub-pictures representing an alternative background, and switching, at the display device, between a first sub-picture of the plurality of sub-pictures and a second sub-picture of the plurality of sub-pictures. Related apparatus and methods are also disclosed.

an illusion of an image which is broader than an image displayed before the switching;
an illusion of an image which is higher than the image displayed before the switching;
an illusion of an image which is broader and higher than the image displayed before the switching; and
an illusion of an image which is, with respect to the image displayed before the switching, at least one of the following;
horizontally distorted; and
vertically distorted. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A display device comprising:
-
a receiver receiving background video comprising encoded video frames, at lease one encoded video frame comprising a plurality of sub-pictures, each of the plurality of sub-picture comprising a different alternative background representing a possible outcome of an interactive video application; a decoder decoding said at least one encoded video frame to produce a decoded video frame; an upsampler which upsamples a first sub-picture of the plurality of sub-pictures of said decoded video frame to a first full upsampled video frame; a renderer rendering the first full upsampled video frame for display as an first alternative background; and a processor switching between the first sub-picture of the plurality of sub-pictures and a second sub-picture of the plurality of sub-pictures of said decoded video frame; the upsampler upsampling the second sub-picture to a second full upsampled video frame after the switching, and the renderer rendering the second full upsampled video frame for display as a second alternative background instead of the first full upsampled video frame; wherein the processor displays a display effect in response to the switching and wherein the display effect comprises at least one of the following;
an illusion of an image which is broader than an image displayed before the switching;
an illusion of an image which is higher than the image displayed before the switching;
an illusion of an image which is broader and higher than the image displayed before the switching; and
an illusion of an image which is, with respect to the image displayed before the switching, at least one of the following;
horizontally distorted; and
vertically distorted.

35. A display device comprising:
-
means for receiving background video comprising encoded video frames, at least one encoded video frame comprising a plurality of sub-pictures, each of the plurality of sub-pictures comprising a different alternative background representing a possible outcome of an interactive video application; means for decoding said at least one encoded video frame to produce a decoded video frame; means for upsampling a first sub-picture of the plurality of sub-pictures of said decoded video frame to a first full upsampled video frame; means for rendering the first full upsampled video frame for display as a first alternative background; and means for switching between the first sub-picture and the plurality of sub-pictures and a second sub-picture of the plurality of sub-pictures of said decoded video frame, and rendering the second sub-picture for display; and the means for upsampling upsampling the second sub-picture to a second full upsampled video frame after the switching, and the means for rendering rendering the second full upsampled video frame for display as a second alternative background instead of the first full upsampled video frame; and means for displaying a display effect in response to the switching, wherein the display effect comprises at least one of the following;
an illusion of an image which is broader than an image displayed before the switching;
an illusion of an image which is higher than the image displayed before the switching;
an illusion of an image which is broader and higher than the image displayed before the switching; and
an illusion of an image which is, with respect to the image displayed before the switching, at least one of the following;
horizontally distorted; and
vertically distorted.
