Abstract:
1. Method for data recording using a data recorder converting first data packet timestamps PAT A based on a first clock rate to second data packet timestamps PAT B based on a second clock rate, said clock rates having a ratio B/A, A being derived from said first clock rate and B being derived from said second clock rate, comprised of the following steps: if no PAT if a PAT wherein PAT B (i)=PAT B (i−1)+D(i) and wherein (i) denotes a current timestamp (M 1 ), (i−1) denotes a previous timestamp (M 2 ), ‘/’ denotes an integer division, R is a remainder used to avoid the accumulation of rounding errors, and PAT_M is the wraparound value of the timestamp counter of said first clock rate.
