Abstract
Official abstract text for this publication.
One object of the invention is a digital video signal comprising a sequence of frames, wherein each video frame in the sequence differs with respect to the previous frame in the sequence by a number of pixels which is not higher than a predetermined pixels maximum threshold amount. Another object of the invention is a method for encoding of a digital source video signal, comprising the steps of receiving a reference frame, receiving a source frame of the source video signal, generating an encoded frame based on the differences between the source frame and the reference frame, wherein the generating of the encoded frame comprises the steps of determining a pixels maximum threshold amount, comparing the reference frame with the source frame and selecting a number of pixels from the pixels which differ between the reference frame and the source frame, the number of selected pixels being not higher than the pixels maximum threshold amount, changing the values of the selected pixels of the reference frame to the values of corresponding pixels of the source frame to provide a reference frame for the next source frame and providing an encoded frame defining pixels changed in the reference frame.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for encoding of a stereoscopic digital source video signal comprising alternate left-eye and right-eye frames, the method comprising the steps of: receiving a reference frame; receiving a source frame of the source video signal; determining a value defining a pixels maximum threshold amount which is lower than the number of pixels in one frame; comparing the reference frame with the source frame to determine the pixels which differ betwe…
