Zusammenfassung:Non-contiguous storage of data objects seriously hampers retrieval speed of said data objects ( 202 ). Furthermore, when multiple data objects are retrieved of which some are fragmented, retrieval time of all data objects gets less predictable. Therefore, it is desirable to retrieve non-fragmented data objects only. For certain cases, this is possible, as not necessarily one specific data object has to be retrieved. In such cases, retrieval of a similar data object, render of the same type, is sufficient. To this, the invention provides among others a method and circuit ( 124 ) for retrieval of data. The invention is especially suitable for retrieving audiovisual data for trickplay. When a first frame selected for rendering is stored fragmented, a second, not fragmented frame is selected and retrieved instead of the first frame.
