    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 (MFn) 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 (MF1), determining a current date (DCOUR) common to the equipment (FE1, FE2), determining a temporal position (POS) of a megaframe (MFn) after the date (DCOUR) in relation to the time base (TB) from a temporal position of the megaframe (MFn) 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).

    摘要: A multiplexing device is coupled to various coding devices. The multiplexing device does not attempt to mutually synchronize the various coding devices but, instead, circumvents such synchronization while making it possible to work with the various coding devices and to obtain synchronous actions at the input of the multiplexer. In particular, the multiplexing device transmits control commands and an instant of action to each of the coding devices.

    摘要: A scrambling and descrambling method that includes reading of original PID and TSC bits in the PID and TSC fields of a packet header of an MPEG2 stream which is at least partially scrambled. A temporary PID may be written in a PID field in place of the original PID, and may be a function of the original PID value and TSC bits according to a correspondence table of an original PID and TSC bits with the temporary PIDs. The value zero may be written in the TSC field in place of the original value, and scrambling of the stream with modified fields may occur. Applications include the satellite transmission of partially scrambled MPEG2 digital signals.
