Audio controls
Output Group Enable
The four output embedders can be individually enabled or disabled, this allows for any other
data already present on the input video to be retained for down-stream use. If required the
ancillary data can also be removed by enabling the VANC blanking.
Audio Gains
In total there are 32 audio gain controls, one for each of the 16 channels of de-embedded audio
and 16 channels of AES audio. The gain controls will give
18dB of gain relative to the input
level up to the point where digital clipping will occur.
Audio delay
Each de-embedder and AES input stereo pair has a set of controls to enable the various delays.
These controls in combination with the video delay controls can be used to delay the audio
with respect to the video and compensate for any small delay between the incoming video and
audio signals or when bypassed, delay the video with respect to the audio by up to several
video lines. See the delays discussion in the introduction for details of how these various
delays interact with each other. The selectable delays are; Frame delay giving a fixed 1 or 2
lines of delay, User delay which selects the global -20 to 80ms delay, TAD (tracking audio
delay) to ensure the audio follows the output video timing, and Dolby E alignment to ensure
the correct positioning of the guardband.
Finally, an indication of the total delay is given. The inclusion of tracking audio delay will
make the indicated total delay vary as the input video timing and external reference change
with respect to each other, as the board edge does not continuously update it will be necessary
to refresh the display by pressing the ENTER button to give a correct length of delay.
Resamplers
The Resample Enable control affects how the audio data is manipulated to change the PCM
delays. On resampled channels (resample enabled) the audio will be continuously resampled
