1. A method for transmission of two consecutive pairs of stereoscopic two dimensional (2D) images, each pair of stereoscopic 2D images defining a three-dimensional (3D) image, the method comprising:

  • decimating each stereoscopic 2D image with a ratio of 2;

    assembling a first portion of the two decimated stereoscopic 2D images into a first composite image, and assembling a second portion of the two decimated stereoscopic 2D images into a second composite image to define a pair of composite images;

    transmitting the pair of composite images as time-consecutive frames; and

    reconstructing complete stereoscopic 2D images from the time-consecutive frames through a de-interlacing process that spatially combines a row or column of a first one of the time-consecutive frames with a row or column of a second one of the time-consecutive frames, the de-interlacing process being free from an interpolation step, and by reconstructing each stereoscopic 2D image from data kept in the other composite image.
