Recording/reproduction and/or editing of real time information on/from a disc like record carrier

摘要

Real time information, such as a digital video signal, is supplied and simultaneously received, converted into/from blocks of information in channel's signals and read/written from/onto a disc-like record carrier. Read/write-scheduling algorithms are used for reading/writing blocks of information recorded in fixed sized fragment areas on the record carrier. Typically one writing action and a plurality of readings actions are used in one read/write cycle of either a fixed duration or of a variable duration. The invention provides for reading and writing of edited files and re-ordering of read actions in a read/write cycle.
