Abstract
There is provided a method of measuring delay variation between first and second elementary streams in a digital audiovisual data stream, comprising detecting and storing digital audiovisual data stream timestamp values, detecting and storing elementary stream timestamp values for the first and second elementary streams, interpolating the digital audiovisual data stream timestamp values and elementary stream timestamp values to form data sets having mutual sampling points, and subtracting the interpolated data set for the first elementary data stream from the interpolated data set for the second elementary data stream to form elementary stream difference values indicative of changes in delay over time between first and second elementary streams.
