A virtual size information is attached to encoded picture data when generating the encoded picture data for example by a transcoder. The virtual size information is used for resizing a picture or a video having a sequence of pictures to increase the subjective quality of the displayed information. The virtual size information is generated on the encoder-side and transmitted to the decoder-side and used by the resizer to resize the transmitted information to a degree, which results in an optimum subjective quality determined by a trade-off between interpolation artefacts and picture size.
