Abstract:
1. A method for video coding of image sequences having images coded in a scaled manner that produces video data containing information which permits the images to be represented in different levels of image resolution defined by at least one of a number of pixels per image representation and image qualities, where the video coding is block-based and describes a displacement of parts of one of the images, contained in the image sequence, by creating at least one block structure that describes the displacement, the block structure being configured such that a block is subdivided into partial blocks and some of the partial blocks are subdivided into successively smaller sub-blocks, comprising: temporarily creating a first block structure for at least one first resolution level and a second block structure for a second resolution level, the first resolution level having at least one of a lower number of pixels and a lower image quality than the second resolution level; comparing the second block structure with the first block structure to determine structural differences in the block structure of each; creating a modified second block structure, based on characteristics of the structural differences, having a structure representing a subset of the second block structure; comparing the modified second block structure and the second block structure based on at least one value proportional to the image quality of each; and video coding of a bit sequence using a programmed processor to form encoded image sequences, representing images with different levels of image resolution, from one of the modified second block structure and the second block structure, having a value directly proportional to an improved quality.
