| 摘要 |
The present invention relates to the domain of control methods of a plurality of formatting equipment (FE1, FE2) of streams (TS) used as backup. The items of equipment receive the streams (TS) and send, to a modulator (MOD1), formatted streams (TS_SFN1, TS_SFN2) comprising a succession of blocks of packets called "megaframe" and megaframe initialisation packets (MIP) used by the modulator (MOD1) to identify in time a megaframe (MF n ) relatively to a time base (TB). According to the invention, the method comprises steps consisting in:
defining a reference date (DREF) that corresponds to the transmission date of a megaframe (MF 1 ),
determining a current date (DCOUR) common to the equipment (FE1, FE2),
determining a temporal position (POS) of a megaframe (MF n ) after the date (DCOUR) in relation to the time base (TB) from a temporal position of the megaframe (MF n ) determined in relation to the date (DREF),
determining a megaframe initialisation packets (MIP) content from the temporal position (POS),
inserting the packet (MIP) in the formatted streams (TS_SFN1, TS_SFN2).
