1. A method for synchronizing a counter in a receiving device for digital data streams, comprising:

  • generating the digital data streams in a transmitting device by sampling analog signals at a sampling frequency synchronized by a system time clock in the transmitting device;

    determining the sampling frequency of one of the data streams in the receiving device;

    synchronizing the counter with the determined sampling frequency of the one of the data streams;

    setting an increment of the counter; and

    determining the increment from a ratio between a program clock reference and the sampling frequency, whereinthe determining the sampling frequency of the one of the data streams in the receiving device is without the transmitter transmitting a value of the system time clock; and

    the frequency of the system time clock in the transmitting device is not the same as the sampling frequency.
