Setting Up the Dolby Digital Audio Input,
10. Set the Digital Level.
You may type a value in the range from -12 to 12 dB. The default is 0 dB.
11. Set the Relative Delay.
The legal range is from -1000 to 1000 ms.
Use this field if you want to adjust the encoding audio delay to synchronize
audio with video in a program which has both.
Example: If you use external video equipment which adds to the video delay,
you type a positive external audio delay value corresponding to the external
video delay.
The resolution is 1 millisecond.
Note: You cannot set a positive relative audio delay greater than the end-to-end
delay determined by the video encoder. For information about the video delay,
see Setting Up the H.264 Video Encoder Delays, page 5-21.
