1. A method for stream synchronization of real-time multimedia transport over a packet network, the multimedia comprising a first stream and a second stream which are buffered and played through respective buffers at receivers, comprising:

  • measuring average transport delays of the first and second streams respectively;

    measuring transport delay jitters of the first and second streams respectively; and

    calculating a delay difference between the first and second streams which corresponds to the average transport delays and the transport delay jitters of the first and second streams, and setting buffer durations in the first and second stream buffers so as to be adapted to the delay difference.
