5.7. De-Embedder
Setting Description
Demb1-Source In the block schematic (cf. "Block Schematic"), you can see that there are 2 de-
embedders. With this setting you select what the source for de-embedder 1
should be. Can be Demb-SDI1, Demb-SDI2, Demb-SDI3 or Demb-SDI4. Can also
be set to follow, in which case this setting will automatically follow the active fill-
input. Default is Demb-SDI1.
Demb2-Source With this setting you select what the source for de-embedder 2 should be. Can
be Demb-SDI1, Demb-SDI2, Demb-SDI3 or Demb-SDI4. Can also be set to follow,
in which case this setting will automatically follow the active fill-input. Default is
Demb-SDI2.
Audio_VO With this setting you select the source of the voice-over audio. Can be Add-On or
SDI. When set to SDI, you can select a specific SDI source with the next setting.
Set to Add-on will automatically set
the first 4 channels
on the add-on bus as
voice-over. Default is SDI.
DembVO_Source With this setting you select what the source for the voice-over de-embedder
should be. Can be Demb-SDI1, Demb-SDI2, Demb-SDI3 or Demb-SDI4. Default is
Demb-SDI1.
DembVO_Ch1 ~
DembVO_Ch4 You can have a total of 4 channels as voice-over. When Audio_VO is set to SDI
you can select a specific channel with the DembVO_Source to be your Voice-over
channels. With these settings, you select which specific channels will be ch1, ch2,
ch3 and ch4 of your voice-over audio. Default are channels 1 through 4.
Phase_Rst If this setting is set to On , the card ensures audio-phase alignment between
multiple audio channels and audio groups, which is necessary for multi-channel
(surround) purposes. If errors in the signal-chain occur the de-embedder blocks
reset synchronously to maintain audio-phase-alignment.
If this setting is set to Off , the card eats-all audio including errors. Even if there
are DBN/ANC/ECC or channel-sequence errors, the de-embedder will pass them.
Be aware that audio-phase-alignment between multiple audio channels and
audio groups cannot be maintained if this setting is set to
Off .
This setting can be helpful to solve problems in the field using equipment which doesn’t
follow the standards correctly.
Audio_Delay Here you can delay all audio between 0ms and 1300ms. Default is 0ms.
