Abstract:
1. A system for synchronizing communications system components coupled via a communications network, comprising: a time information transmitter for transmitting time information relating to the communications system components; a time information reception device in each system component for receiving time information from the time information transmitter; a clock generator in each system component with a controllable clock frequency for prescribing a transmission data rate for communication data which are to be transmitted; a real time clock in each system component whose timing is controlled by the clock generator; a comparison device in each system component for comparing received time information with a current time value indicated by the real time clock; a clock frequency controller in each system component for controlling the clock frequency of the clock generator based on a comparison result from the comparison device; an input buffer in each system component for buffering a data stream received via the communications network, where reading of data elements in the data stream from the input buffer is determined by the clock frequency of the clock generator; a filling level detection device in each system component for detecting a filling level of the input buffer; and a clock frequency controller in each system component for readjusting the clock frequency of the clock generator based on the detected filling level.
