First Claim
1. A method for demultiplexing a multiplexed image frame configured to have a precursor format, wherein the multiplexed image frame comprises a horizontal pixel count and a vertical pixel count that define a first aspect ratio, wherein the precursor format of the multiplexed image frame comprises a right image in a first portion of the multiplexed image frame and a left image in a second portion of the multiplexed image frame, wherein one of the right image or the left image is divided into a plurality of blocks, the plurality of blocks being re-arranged from a first block arrangement to a second block arrangement different from the first block arrangement, and the other one of the right image or the left image comprises a horizontal pixel count and a vertical pixel count that define a second aspect ratio, wherein the first and second aspect ratios are substantially the same, the method comprising:
- receiving the multiplexed image frame;
generating a first demultiplexed image for the one of the right image or the left image in the multiplexed image frame, wherein the generating comprises reverse re-arranging the plurality of blocks in the one of the right image or the left image in the multiplexed image frame from the second block arrangement to the first block arrangement different from the second block arrangement and combining the plurality of blocks of the first clock arrangement; and
generating a second demultiplexed image for the other one of the right image or the left image in the multiplexed image frame.

Abstract
A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames. The method includes compressing stereoscopic image source data at varying levels across the frame, thereby forming left images and right images, and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Alternately, single frames may contain two right images in a first two portions of each single frame and two left images in a second two portions of each single frame, wherein each set of right and left images may be processed differently. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed.
