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 (1) 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 (2) 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. (3) 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 viewer perceives a 3-D effect. In another example, left-eye and right-eye image are superimp

Claims

1. A method for decoding encoded content including a plurality of encoded frames, comprising: receiving by an image processing device the encoded frames, wherein the encoded frames comprise a first type frame, a second type frame, and at least one null frame; detecting by the image processing device a synchronization signal corresponding to the encoded frames; and compiling by the image processing device the encoded frames into a frame-sequential stream of frames, according to the synchronization signal, wherein when the frame-sequential stream of frames is displayed on a display device, the at least one null frame is not displayed, the first type frame utilizes a full resolution of the display device, and the second type frame utilizes the full resolution of the display device to display a full resolution of the decoded content. || 14. A system comprising: a display configured to display visual content; and a decoder configured to: extract an encoded stream of frames having a first type frame, a second type frame, and at least one null frame from a content source; obtain synchronization information from the encoded stream of frames; generate a frame-sequential stream of frames for the first type frame, the second type frame, and the at least one null frame based on the synchronization information; and transmit the frame-sequential stream of frames to the display, wherein the display or the decoder is configured to discard the at least one null frame when the frame-sequential stream of frames is displayed, and wherein the first type frame utilizes a full resolution of the display when displayed and the second type frame utilizes the full resolution of the display when displayed to display a full resolution of the visual content. || 20. A method for decoding encoded content including an encoded stream of frames, comprising: extracting by a processing element the encoded stream of frames having a first type frame, a second type frame, and at least one null frame from a visual content; 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 type frame, the second type frame, and the at least one null frame based on the synchronization information; and transmitting by the processing element the frame-sequential stream of frames to a display, wherein the display is configured to discard the at least one null frame when the frame-sequential stream of frames is displayed, and wherein the first type frame utilizes a full resolution of the display when displayed and the second type frame utilizes the full resolution of the display when displayed to display a full resolution of the visual content.
