Abstract:
1. A method for determining based on a linear time axis a start packet and an end packet for an editing operation of a recorded data stream, said data stream including non-equidistant application packets to each one of which an arrival time stamp indicating the time when the packet had arrived is assigned, said data stream including at least a first application packet and a subsequent second application packet, wherein gaps can be included between succeeding application packets which gaps can comprise stuffing packets, and wherein as part of navigation data a mapping list is available which can be used for converting a point on the time axis to a corresponding application packet, said method including: inputting a discrete time from said linear time axis, said discrete time being a start time or an end time for said editing operation, wherein said discrete time has a time value between the time value of said first arrival time stamp and the time value of said second arrival time stamp; mapping said discrete time on said data stream; if said discrete time points into an application packet, comparing a first time difference between said first arrival time stamp and said discrete time with a second time difference between said discrete time and said second arrival time stamp, and selecting that one of the two application packets to which the smaller time difference is related;
