Setting Up the Linear/Dolby E Audio Input,
5. If Digital was selected as the input type above, select one of the four connectors
to use as the digital audio input (Digital Input). You can select AES1, AES2,
AES3, or AES4.
Note: Digital Input is only available for encoders equipped with a Multiple
Channel Audio (MCA) card.
6. If Embedded was selected as the input type above, select the embedded packet
pair (Embedded Input).
The HD-SDI video input can contain up to 8 stereo audio channels each
represented by a packet 1 to 4 and pair 1 or 2. You can transfer up to 4 of these
channels.
7. The Bit Rate field displays the bit rate of the signal. This is read-only.
8. 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.
Note: You cannot set a positive relative audio delay greater than the end-to-end
delay determined by the video encoder.
9. Set the External Delay.
The legal range is from 0 to 2000 ms.
If you use an external audio encoder which adds to the audio delay you type a
delay value corresponding to the external audio delay.
10. Click Apply.
