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.

A method is provided for channel decoding a data stream containing useful data and redundant data, the data stream exhibiting at least one known source-coded errored bit sequence which identifies a pre-determined position within the data stream, wherein the data stream is channel decoded, the source-coded errored bit sequence is determined from the channel-decoded data stream, and the data stream is again channel decoded taking into consideration the detected source-coded errored bit sequence.

The discrete cosine transform of the prediction error is not necessarily calculated, rather the DCT of the original picture to be transmitted and the DCT of the temporally preceding reconstructed picture are calculated separately from one another. By comparing the amplitudes of the coefficients from the original signal with respect to the difference between the coefficients from the original signal and the reconstructed picture, a decision is made for each coefficient as to whether the coefficient of the original signal or the difference between the coefficients is transmitted.
