How to identify the spatial synchronization of digitally encoded video image and / or video sequence syntax

摘要

(57) Abstract Concerning each position of the analytical grid (GA) the analytical grid (GA) where this invention, synchronization being able to point to the three-dimensional position of the video image (IM), being the manner which decides the position of the early coded grid (GI) making use of the coded block of the aforementioned image (IM), a) is formed from coded block and at least corresponds to the image (IM) of part, direction of the image (IM) line and/or image (IM) line and step and b which are made to move to the direction of verticality) making use of dispersion cosine conversion (TCD) conversion of each block of the analytical grid (GA)The activity parameter which coefficient Fu, decides v, displays activity of the image each analytical grid (GA) concerning position, (AM and ES) step and c) aforementioned activity parameter which are calculated (AM and ES) the analytical grid which reaches minimum (GA) the manner which features that it consists of the step which decides position.
