DELAY ADJUSTMENT USING SAMPLE RATE CONVERTERS |
摘要 |
A method and apparatus for adjusting the delay of a first data stream relative to a second data stream is disclosed. An apparatus receives first and second data streams having identical content. A timing difference between the first and second data streams is estimated. At least the leading one of the data streams is applied to a sample rate converter. The sample rate converter is configured to receive a data stream at an input sampling rate and to output the data stream at an output sampling rate. Based on the estimated timing difference, delay is applied to the leading one of the data streams by changing the sampling rate of the sampling rate converter. The output sampling rate of the sampling rate converter may be adjusted until both data streams are aligned in time.
