    摘要: Storing of data items in a memory (31) is provided wherein the data items are divided into successive data pieces of decreasing significance, and the data pieces are stored in respective parts of the memory (31), and when applying a data piece to the memory (31) in case all candidate memory parts are assigned to other data pieces: if the significance of the applied data piece is lower than a lowest significance of the other data pieces, discarding the applied data piece; if the significance of the applied data piece in one of the candidate memory parts at expense of a given other data piece which has a lower significance that the significance of the applied data piece, wherein the significance value of a data piece is based on a total or absolute distortion value of the data item. Advantageous use of the invention is made in applications using a device of fixed storage capacity for storing a flexible number of compressible data items, such as video, images, audio, speech.
