| 摘要 |
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). The present invention also proposes a device for sample rate adaptation in a telecommunication system, operating according to such a method. |
