Audio Handling
The V6404/06/08/18 provide some functionality for dealing with embedded audio. These functions are
summed up in a group called 'AUDIO'.
The main task is to 'transfer' the embedded audio information between the different domains, i.e. from SD
to HD or vice versa, whilst preserving its original digital content.
Audio is de-embedded before video processing, then re-embedded afterwards. The audio delay is
automatically matched to the video processing delay to within 1ms.
