Abstract
A method is described for synchronizing the transmission of a stream to a group of end-terminals. The method is used in a system comprising a station transmitting a packetized stream over a network to at least a first and second network node. Each network node comprises a variable delay unit and each network node is connected to one or more end-terminals. In the method the synchronization unit receives arrival time information of a packet in the broadcast stream at the first and second network node. Delay information is calculated for the first and second network node on the basis of the arrival time information of the packet. Further, the delay information is transmitted to the first and second network node so that the variable delay unit in the first and second network node is able to transmit the broadcast stream to the first and second end-terminal in a substantially synchronized way.
