Abstract

One particular implementation of the present invention may take the form of a method and system for encoding decoding 3-D multimedia content. In one example, visual content having a plurality of source frames may be processed to create a plurality of first and second type frames from each of the plurality of source frames. The plurality of first and second type frames may be arranged to create modified content, and generating a distinguishing signal for the visual content, which may distinguish the first type frame from the second type frame. In another examples, the present invention may take the form of a method decoding 3-D multimedia content encoded with at least content frames and null frames. The method may operate to receive the3-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.

Implementations of the present invention involve methods and systems for encoding and/or transmitting high definition 3-D multimedia content, such as 3-D video. The frames of the 3-D video may be encoded or transmitted in a frame-sequential fashion, with some image frames intended for the viewer's right eye and other frames intended for the viewer's left eye. To account for the addition of frames intended for each eye of the vie

Claims

1. A method for encoding visual content for at least one of transmission or display, the method comprising: receiving by a processing element the visual content comprising a plurality of source frames; creating by the processing element for each source frame in the plurality of source frames a first type frame and a second type frame, wherein each of the first type frame and the second type frame utilize a full resolution of a display device for displaying the visual content; arranging by the processing element the plurality of first type frames and second type frames to define a modified content; and generating by the processing element a distinguishing signal for the visual content, wherein the distinguishing signal distinguishes the first type frame from the second type frame. 10. A method for decoding encoded content including a plurality of encoded frames, comprising: receiving by a processing elementthe encoded frames, wherein the encoded frames comprise at least one content frame and atleast 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 offrames; generate a frame-sequential stream of frames for the first image type, the secondimage type, and the at least one null image based on the synchronization information; andtransmit 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.
