    摘要: 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.

    摘要: A coding method codes a sequence of digitized images with a plurality of macro blocks in error-prone networks in which case the macro blocks in a section of the image are coded in a first intra-coding mode depending on predetermined criteria. In addition, the macro blocks in a section of the image are coded in a second intra-coding mode or in an inter-coding mode in which case in the inter-coding mode for the macro blocks, movement vectors are selected from the number of accessible reference images. The selection from the number of accessible reference images is limited in such a way that referencing takes place from image areas that were not subjected to the first intra-coding mode at a later stage.

Upon download, the composition of the parts of the file which are obtained from a plurality of source stations provides a new watermark which can clearly be associated with the target station. By storing information about forwarded watermark elements of a network server, it is possible to reconstruct for each file the network station from which this file originates.

    摘要: Pixels with associated pixel values form a sequence of digitized images that are encoded by predicting pixels of the images and encoding the prediction errors. At least a part of the pixels are encoded by determining trajectories, each running through a pixel to be encoded and through other previously encoded pixels from the image of the pixel being encoded and/or from one or more images that are temporally proximate to that image. For each of the trajectories determined, a valuation parameter is in inverse proportion to the deviations in the uncoded associated pixel values of the other pixels along a trajectory. A predicted pixel value of the pixel to be encoded is determined based on the other pixels of the trajectory with the highest valuation.
