Problems solved by technology

However, this feature, especially allowing format changes on a picture-by-picture basis, imposes practical and performance limitations that do not necessarily improve encoding performance
While GOP / GOP selection is possible and practical, its performance improvement is unclear

Embodiment Construction

[0022] The present invention will now be described with reference to Figures 4-7(b) of the accompanying drawings.

[0023] FIG. 4 is a flowchart of an exemplary encoding method of a video signal according to an embodiment of the present invention.

[0024] In the exemplary method 12 shown in Fig. 4, in a first step 14 it is determined whether there are at least first and second substantially identical image regions in a frame of the video signal. In a second step 16, in response to an affirmative determination in step 14, the picture information in each image area is compression-encoded without reference to another picture area.

[0025] FIG. 5 is a block diagram illustrating features of an exemplary video signal encoder 18, according to an exemplary embodiment.

[0026] Exemplary video signal encoder 18 includes analyzer 20 and compression encoder 22 . The analyzer 20 is arranged to receive a video signal 24 and analyze the video signal 24 to determine whether a picture of ...

Abstract

The invention relates to the compression coding of video signals. The invention may be applied in some embodiments to the compression coding of three dimensional television (3DTV) signals. The invention provides a method of coding of a video signal, in which the presence of at least a first image area and a second image area in a picture, in which the images in the first image area and in the second image area are substantially identical is determined. In response to a positive determination, picture information in one image area is compression coded without reference to picture information in another image area. The invention also provides a video coder for coding a video signal.

Description

technical field [0001] The invention relates to compression coding of video signals. In some embodiments, the present invention is applicable to compression coding of three-dimensional television (3DTV) signals. Background technique [0002] While viewing conventional electronic television images on two-dimensional (2D) display screens has been the norm for many years, there has also been a strong interest in extending the experience to stereoscopic or three-dimensional television (3DTV). Such schemes aspire to provide individual signals to each eye, allowing the brain to construct the illusion of three-dimensional space, thus providing more realism. The use of two separate but closely related images of the same scene delivered to each eye independently provides the basis for so-called stereoscopic TV. [0003] Systems have been proposed that can support 3DTV with minimal additional processing, using existing 2DTV compression hardware and simple adaptation of the delivery ...
