ABSTRACT:
In a method of recording real-time information on an information carrier, e.g. audio on an optical disc, the real-time information is compressed to units comprising a variable amount of compressed data, and playback parameters are determined in dependence of the compressed data. The playback parameters comprise an access list (Main_Acc_List) having entries, each subsequent entry being assigned to a subsequent interval of a fixed playback time and comprising a pointer (Entry[N]) to a unit within said interval. In a player the real-time information may be accessed at a selected point of playing time. The corresponding entry in the access list is determined by dividing the selected time by the interval. The entry provides the pointer (Entry[N]) to the unit corresponding to the selected playing time. Interpolation may be used for calculating an address at a selected playing time within an interval, and the accuracy may be improved by a margin parameter (Access_Flags[N]), which indicates the maximum distance between the unit of the selected playing time and the interpolated address.
