Abstract
A method of modifying data in an encoded data signal corresponding to successive pictures divided into sub-pictures, for providing an output modified data signal . In particular, this model can be used for the insertion of an additional data signal into a compressed video data signal . The proposed arrangements/diagrams according to the method are based on a transcoder arrangement including at least partial decoding and partial re-encoding. This method leads to a cost-effective solution compared with the prior art comprising a minimum number of functional DCT/IDCT sub-steps, taking advantage of simplifications and combinations between different sub-steps.
