Abstract:
1. Device for rendering real time information from a record carrier, which device comprises read means ( 22 , 27 , 28 ) for retrieving the real time information and playback parameters related thereto from a track on the record carrier, and speed means ( 31 ) for rendering the real time information at a speed different from the real time speed based on speed pointers, which real time information is subdivided into units (VOBU), a number of consecutive units constituting a cell and local playback parameters being included in the units, which local playback parameters comprise speed pointers (VOBU 13 SRI) to units located at a forward and/or backward distance relative to the unit in which the pointers are included, characterized in that the speed means ( 31 ) comprise calculation means ( retrieving a unit address map (VTS-VOBU-ADMAP) that includes the addresses of a consecutive sequence of units, determining a number of units within the cell by determining a position of the addresses of said first and last unit in the unit address map, and dividing the cell playback time by the number of units.
