Configuring The Audio Processing; Selecting The Audio Groups That Will Be De-Embedded - evertz 7700 Manual

6.8.

CONFIGURING THE AUDIO PROCESSING

The SMPTE 299M standard permits up to 4 groups of 4 audio channels to be embedded into the 1.5 Gb/s
video bitstream. The 7710UC-HD de-embeds two groups of audio from tin incoming SDI that are the
source for re-embedding on the HD SDI output video. The Audio menus are used to configure the de-
embedder and embedder groups. The chart below shows the items available in the Audio menu. Sections
6.8.1 to 6.8.2 give detailed information about each of the menu items.
De-embedder A
De-embedder B
Embedder A
Embedder B
Audio Delay
Embedder A ch 1
Embedder A ch 2
Embedder A ch 3
Embedder A ch 4
Embedder B ch 1
Embedder B ch 2
Embedder B ch 3
Embedder B ch 4

6.8.1. Selecting The Audio Groups That Will Be De-Embedded

There are two controls that set the source groups for the two de-embedders. For simplicity, only one
control will be shown in the manual.
Audio
De-embedder A
Group 1
Group 2
Group 3
Group 4
Sets the audio group source for de-embedder A
Sets the audio group source for de-embedder B
Sets the audio group destination for embedder A
Sets the audio group destination for embedder B
Adjusts the audio delay from the nominal video delay
Sets the audio channel source for channel 1 of embedder A
Sets the audio channel source for channel 2 of embedder A
Sets the audio channel source for channel 3 of embedder A
Sets the audio channel source for channel 4 of embedder A
Sets the audio channel source for channel 1 of embedder B
Sets the audio channel source for channel 2 of embedder B
Sets the audio channel source for channel 3 of embedder B
Sets the audio channel source for channel 4 of embedder B
With these controls, you can set the source group for De-embedder A and
B. Under normal conditions the settings for De-embedder A and B should
be different otherwise the audio will be repeated on the HD SDI output.
The default group for de-embedder A is group 1 and the default group for
de-embedder B is group 2.
