ABSTRACT:
A device for rendering real time information arranged in cells constituted by units encoded at a variable bit rate, e.g. video on a DVD, is described. The device has various trick play modes for rendering the information at a different speeds based on speed pointers. A limited amount of speed pointers is included in the information stream. The device has a calculation unit32for calculating further speed pointers based on estimating the playback time of the units by retrieving cell playback information (C-PBIT) that includes the addresses of the first unit and the last unit within the cell and a cell playback time, retrieving a unit address map (VTS-VOBU-ADMAP) that includes the addresses of the units, determining a number of units within the cell by determining a position of said first and last unit in the unit address map, and dividing the cell playback time by the number of units.
