Patent number: 6717933
Abstract: The invention relates to a converter (CVT) and a conversion method for converting an input data packet stream (IDPS) of consecutive data packets (DP0,0, DP1,0, DP2,0 . . . DPN−1,0) each data packet including user (US0, US1, US2, . . . USN−1) data in the form of a predetermined number (Nsymbol0; Nsymbol1; NsymbolN−1) of consecutive data symbols (S0,0(0), S0,0(1) . . . S0,0(Nsymbol0−1); S1,0(0), S1,0(1) . . . S0,0(Nsymbol0−1); S2,0(0), S2,0(1) . . . S2,0(Nsymbol2−1); . . . SN−1,0(0), SN−1,0(1) . . . SN−1,0(NsymbolN−1−1)) from a plurality of N user channels (ch-0, . . . ,ch-N−1), each user channel having a predetermined transmission rate TR0, TR1, TR2, . . . ,TRn, . . . TRN−1, being defined as a basic transmission rate TRB or an integer multiple TRn=Kn*TRB thereof, into an output data symbol stream (ODSS) in which a respective number Kn of data symbols (S0,0(0); S1,0(0), S1,0(1), S1,0(2), S1,0(3); S2,0(0); . . .
