    摘要： Disclosed are methods and devices for compressing and decompressing video data streams, according to which the statistical relationship between image symbols and the context assigned thereto is used for compression. Particularly disclosed is a context-sensitive encoding unit in which the image symbols filed in an image storage are assigned to different encoding branches via a context switch, where they are encoded and compressed by a Golomb encoder and a run length encoder.

    摘要： Files which are available for dissemination in a controlled peer-to-peer network are provided with a watermark comprising a large number of watermark elements. 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： A method determines a predicted image area for an image area, in which a temporal predictor for the image area is determined based on a reconstructed image that precedes said image, a local predictor for the image area is determined within a reconstructed image area of the image, a margin of error between the image area and the image area predicted image area is determined by the local predictor using the reconstructed image area and by the temporal predictor using one of the preceding images. A predicted image area can be reconstructed. Also disclosed are an establishing device for carrying out the method for determining a predicted image area as well as a reconstructing device for carrying out the reconstruction method.

    摘要： A method and apparatus are provided for storing and processing picture information of temporally successive pictures wherein in each case at least one picture area is selected from each temporally preceding picture taking into account, the picture information determined from each selected picture area is stored with an assignment information item, which enables an assignment of the respective picture area and thus also of the picture information of the respective picture area to the corresponding picture and to the position of the picture area within the corresponding picture, at least one mixed picture is formed from the picture information of the respectively stored, selected picture areas, taking the account of the assignment information, and the mixed picture is used in the context of a motion estimation, a motion compensation or an error masking for an image.

    摘要： A method is described for transmitting a byte stream (1) from a transmitter unit to a receiver unit in a network protocol, with the following steps: Removal of at least one data area (4a,4b) of the byte stream (1) from the byte stream, Transmission to the receiving unit of information relating to which data area (4a,4b) or which data areas (4a,4b) has or have been removed from the byte stream (1) and/or relating to the way in which the shortened byte stream is to be further processed, Transmission of the byte stream (5) shortened by at least one data area (4a, 4b) to the receiver unit, which, from the information and the shortened byte stream, determines and further processes the at least one data area removed by the transmitter unit.
