    Abstract: In video coding image sequences, images are coded in a scaled manner to obtain video data which represents the image in multiple steps from a defined image resolution or image quality (e.g., according to the data rate), and the resolution is defined by the number of image pixels of each represented image. Coding is block-based, i.e., for a description of an approximate movement of parts of one of the images in the image sequence, at least one block structure is produced describing the movement. The block structure produced includes a block divided into partial blocks which are in turn divided into sub-blocks. A first block structure is produced temporally for at least one first resolution level and a second block structure is produced for a second resolution level. The first resolution level has a lower image pixel number and/or image quality than the second resolution level. The second block structure is compared to the first block structure such that differences in the block structure are determined, such that on the base of the properties of the structure differences, a modified second block structure is produced. The structure thereof represents one part of the second block structure. Subsequently, the modified block structure and the second block structure are compared based on at least one value which is proportional to the quality of the image and the block structure and the value thereof is directly proportional to an improved quality based on the coding of the bit sequence.

    Abstract: A series of decoded images is generated from a series of original images encoded by a first encoding technique following movement-compensated, predictive encoding, where a starting image of a group of successive original images that are to be encoded is defined by a second encoding technique following movement-compensated, temporally filtered partial band encoding based on a determined encoding property of a decoded image of the group of images that are to be encoded, the decoded image is used for generating an output image having a low resolution level, before the images are encoded. At least one output image is generated on each level of resolution from the successive original images of the group of from at least one decoded image during image encoding. The decoded images are provided only with a reduced quality while the reconstituted images are of great quality.

    Abstract: A plurality of scene data describing at least one scene are transmitted by a data carousel from a transmitter to at least one receiver of a unidirectional broadcast system. The data carousel is used to transmit an index file to the receiver, a temporal arrangement of the scene data file being encoded in terms of data systems in the index file, to graphically represent and/or decode the scene.
