METHOD AND CIRCUIT FOR RETRIEVING DATA

摘要

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, 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.
