3D video transmission on a legacy transport infrastructure
First Claim
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.

Abstract
The present disclosure relates to a method for transmitting two consecutive pairs of images. The method may include decimating each image with a ratio of 2, assembling the two decimated images of each pair in a composite image, transmitting the composite images, and reconstructing complete images from the composite images. In decimation, the information removed from the images of the first pair may be kept in the images of the second pair, from the spatial point of view, and the complete images may be reconstructed by de-interlacing processing from the composite images.

9. 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;
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, without interpolating, 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 and by reconstructing each stereoscopic 2D image from data kept in the other composite image. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for transmission of two consecutive pairs of stereoscopic two dimensional (2D) images, with the two stereoscopic 2D images of each pair of stereoscopic 2D images being stereoscopic views from a spatial point of view, each pair of stereoscopic 2D images defining a three-dimensional (3D) image, the method comprising:
- decimating each stereoscopic 2D image with a set ratio;
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 configured to place, without interpolating, a row or column of a first one of the time-consecutive frames next to a row or column of a second one of the time-consecutive frames and by reconstructing each stereoscopic 2D image from data kept in the other composite image. - View Dependent Claims (18, 19, 20, 21, 22, 23)
