CONFIGURING THE AUDIO PROCESSING (MODEL 7712HDC-SN-EAES4 ONLY)

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 model 7712HDC-SN-EAES4 de-embeds two groups of audio that are the source for
re-embedding on the SDI output video. The Audio menus are used to configure the de-embedder and
embedder groups. The menu is not available on the 7712HDC-S version, as it does not process audio.
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

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.

6.8.2. Selecting The Audio Groups That Will Be Embedded

The model 7712HDC-SN-EAES4 has two embedders that each insert one group of audio on the SDI
output. The source for Embedder A is the audio being extracted by de-embedder A. The source for
Embedder B is the audio being extracted by de-embedder B. There are two controls that set the audio
groups where the embedders will put the audio on the SDI output. For simplicity, only one control will be
shown in the manual.
This control determines the line number where VITC will be inserted in 625
line video when the VITC Generator control is set to On.
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
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 SDI output.
The default group for de-embedder A is group 1 and the default group for
de-embedder B is group 2.
