Abstract (en)

[origin: WO2009103638A1] The invention relates to a method for broadcasting a data stream in a network including at least two separate transmitters supplied by a head end, said stream being organised into data frames and including at least one time marker. According to the invention, the method comprises the following steps at the head end: obtaining a first time reference from an external source; obtaining a second time reference from said data stream received by said head end; comparing said first and second time references in order to determine a time shift between said first and second time references; transmitting said time shift or at least one time marker modified on the basis of said time shift in order to compensate for a transport time variation between said head end and said transmitters.
