<P>PROBLEM TO BE SOLVED: To provide a method for processing a stream of multiplexed packets transporting multimedia data according to an MPEG-2 format. <P>SOLUTION: A multiplexed packet stream (10) is transmitted at a high bitrate to an intermediary network (12) having low bitrate transmission channels (14<SB>1</SB>-14<SB>n</SB>). The high bitrate stream is treated upstream of the intermediary network (12) carrying out the steps of: demultiplexing the high bitrate stream (10) in order to insert packets (1-44) of data into low bitrate streams (16<SB>1</SB>-16<SB>n</SB>) transmitted by the transmission channels (14<SB>1</SB>-14<SB>n</SB>); and alternating, in a synchronized way for a set of low bitrate streams, the insertion of packets of data with the insertion of synchronization packets (M1-M4) in these low bitrate streams, so that these low bitrate streams are transmitted in the intermediary network with a same low bitrate and a same alteration between the packets of data and the synchronization packets. <P>COPYRIGHT: (C)2010,JPO&INPIT |
