  • Patent number: 7035215
    Abstract: The present invention proposes a method for synchronization adaptation of asynchronous digital data streams comprising the steps of providing a first digital data stream (PCM_IN) at a first sample rate (CLK—1); inputting said first digital data stream (PCM_IN) to a sample rate conversion means (SRC); supplying data output from said sample rate conversion means (SRC) to a processing element (BUFFER); storing said supplied data into said processing element (BUFFER); and outputting said data stored in said processing element as a second digital data stream (PCM_OUT) at a second sample rate (CLK—2), with said first and said second sample rates (CLK—1, CLK—2) being different from each other; and is characterized by the further steps of detecting a state (BUFFER_STATUS) of said processing element (BUFFER); and controlling said sample rate conversion means (SRC) dependent on the detected state of said processing element.

  • Patent number: 6876666
    Abstract: The present invention proposes a method for sample rate adaptation in a telecommunication system comprising the steps of: supplying a first stream (PCM_IN) of data cells via a network (ATM) operated at a first sample rate (CLK—1; CLK—2), passing said data stream through a data modifying means (DOD), outputting said data stream out of said data modifying means (DOD) to a processing element (BUF:—1; BUF—2), storing said output data is said processing element (BUF—2; BUF—1); and outputting said data from said processing element as a second digital data stream (PCM_OUT) at a second sample rate (CLK—2, CLK—1), said first and said second sample rate being different from each other; wherein said method comprises the further steps of detecting a state (BUFFER_STATUS) of said processing element (BUF—2; BUF—1); and controlling said data modifying means (DOD) dependent on the detected state of the processing element (BUF—2; BUF—1).
