Abstract
A method for demultiplexing frames of compressed image data is provided. The image data includes a series of left compressed images and a series of right compressed images, the right compressed images and left compressed images compressed using a compression function. The method includes receiving the frames of compressed image data via a medium configured to transmit images in single frame format, and performing an expansion function on frames of compressed image data, the expansion function configured to select pixels from the series of left compressed images and series of right compressed images to produce replacement pixels to form a substantially decompressed set of stereo image pairs. Additionally, a system for receiving stereo pairs, multiplexing the stereo pairs for transmission across a medium including single frame formatting, and demultiplexing received data into altered stereo pairs is provided.
