Zusammenfassung |
AB |
[EN] An input data stream coded using a first coding method and containing at least one coded digitized image is converted into an output data stream that is coded using a second coding method. The input data stream has first intra-blocks, each of which is coded in a first prediction mode of a plurality of first intra-prediction modes, and the output data stream has second intra-blocks, each of which is coded in a second prediction mode of a plurality of second intra-protection modes. The second prediction modes of one or more second intra-blocks are determined with the aid of the first prediction modes for one or more first intra-blocks and the second intra-blocks are coded using the second prediction modes that are thus determined. In particular, prediction errors that are assigned to the first intra-blocks are taken into consideration for the determination of the second prediction modes. |
