Providing Compatibility for 2D and 3D Television Broadcasting Systems
Abstract
Problem: The introduction of 3D television broadcasting systems is now stalled by the lack of a compatible television broadcasting format which would allow 3D content to be viewed on 2D TVs in 2D format. From the economic point of view, it is important that any television content produced, including films, all kinds of broadcasts, advertisements, etc., can be watched on any TV screen, either 2D or 3D. Purpose: Search for a way to construct a stereoscopic image processing algorithm for a compatible format. Methods: The solution is based on the consideration of human vision features, on the methods of converting 2D images into 3D, on image compression, and also on a large amount of experimental measurements made in a group of spectators who were asked to observe stereoscopic images synthesized in various transmission formats, examining the visibility of the resulting distortions. Results: А principle of constructing a compatible format for 3D television broadcasting has been developed. In this format, the left component of a stereopair image is transmitted as the main one, but a small part of the frame transmission time, corresponding to a small area of the transmitted image, is allocated to transmit a signal containing the information which, using the left component, forms the right component of the stereopair. As such a signal, the screen parallax map pixels are used, whose transmission is stretched to 3-4 frames. In a 3D television receiver, using a zero-order interpolation method, screen parallax maps are reconstructed from these pixels. Using these maps along with the left components of the stereo pair, you can synthesize the missing right components of the stereo pairs, reproducing the stereoscopic image. 2D TV receivers simply play back the left component of the stereo pair. Practical relevance: Constructing a compatible format for 3D television broadcasting makes it possible to significantly reduce the complexity of developing broadcasting standards.Published
