Abstract

One particular implementation may take the form of a method and system for decoding 3-D multimedia content. In one example, the present invention may take the form of a method of decoding 3-D multimedia content encoded with at least content frames and null frames. The method may operate to receive the 3-D multimedia content, extract at least one content frame, at least one null frame, and display information. The method may further operate to reconstruct the content and null frames in a display-sequential manner using the display information to indicate the display order of the at least one content frame. In some examples, the method and system for encoding and decoding multimedia content may encode the multimedia content such that the at least one null frame may not be displayed by a display device.

Background

FIELD OF THE INVENTION

Aspects of the present invention relate to display of 3-D multimedia content. More particularly, aspects of the present invention involve a system and method for encoding and transmitting high definition 3-D content to a display device.BACKGROUND

Three dimensional (3-D) imaging, or stereoscopy, is a technique used to create the illusion of depth in an image. In many cases, the 3-D effect of an image is created by providing a slightly different image of a scene to each eye of a viewer. The slightly different images may present two perspectives of the same object, where the perspectives differ from each other in a manner similar to the perspectives that the viewer's eyes may naturally experience when directly viewing a three dimensional scene. When the two images are viewed at the same time, the image is perceived as having depth.

Several methods exist to provide a 3-D effect to an image. An anaglyph image may present the two images for each of the viewer's eyes in different colors, such as red and blue-green. To achieve the 3-D effect, the viewer wears glasses with color filter lenses that filter the color(s) so as to present only one of the images for each eye. Thus, the viewer's right eye receives the red image while the viewer's left eye receives the blue-green image. When the left-eye image and the right-eye image are viewed at the same time, the image is perceived as having depth.

Claims

1. A method for decoding encoded content including a plurality of encoded frames, comprising: receiving by a processing element the encoded frames, wherein the encoded frames comprise at least one content frame and at least one null frame; detecting by the processing element a synchronization signal corresponding to the encoded frames; and compiling by the processing element the encoded frames into a frame-sequential stream of frames according to the detected synchronization signal, such that the at least one null frame is not displayed when the frame-sequential stream of frames is displayed. 15. A system comprising: a display device capable of displaying three-dimensional (3-D) multimedia content; and a decoder configured to: extract an encoded stream of frames having a first image type, a second image type, and at least one null image from a 3-D content source; obtain synchronization information from the encoded stream of frames; generate a frame-sequential stream of frames for the first image type, the second image type, and the at least one null image based on the synchronization information; and transmit the frame-sequential stream of frames to a display device, wherein the display device is configured to discard the null images when the frame-sequential stream of frames is displayed. 20. A method for decoding encoded content including a plurality of encoded frames, comprising: extracting by a processing element an encoded stream of frames having a first image type, a second image type, and at least one null image from a 3-D content source; obtaining by the processing element synchronization information from the encoded stream of frames; generating by the processing element a frame-sequential stream of frames for the first image type, the second image type, and the at least one null image based on the synchronization information; and transmitting by the processing element the frame-sequential stream of frames to a display device, wherein the display device is configured to discard the null images when the frame-sequential stream of frames is displayed.
