Video Delay
For compensation of any kind of audio processing delay within the
chain of devices you may use a Video Delay.
Position “0” turns the delay function off.
Important note! The video delay is a static setting. I.e. you must not change it on air! This will
cause a resynchronization of the SDI stream. Since the video delay is part of the presets, you must
be careful when creating presets to use the same value in all presets!
Generate new SDI If there is the need to replace the structure of the Ancillary Audio
Audio Structure Data Blocks you can clean the whole area and generate a new
structure. If the option is checked, there will be no signal available at
the group output as long as there is no SDI Out Grx checked.
SDI Out Grx This check box enables each of the 4 SDI audio groups to be used
individually by the C8405 embedder. If it is not checked and “Generate
new SDI Audio Structure” is not enabled, the audio data from the
input will travel untouched from the SDI input to the output.
Silence Mutes the respective audio channel at the embedder side.
Delay The inputs of the embedder routing matrix can be taken either
from the de-embedder or from the C8k audio busses in any
combination. If they are taken from the de-embedder and a Video
Delay is introduced, the Video Delay will automatically be
compensated for those signals.
For signals coming from the C8k audio busses an independent delay
per single channel may be used.
Important note! These delay settings are also static. You must not use this feature if you shuffle
audio signals with different delay times. It will cause strange effects at the moment of switching,
because the delay length is changing!
Mux Format The signals from the C8k audio busses may be received in 2CH or
8CH multiplex mode. If they must be received in 8CH multiplex mode
there is only one bus selector available for each of the two eight
channel groups.
Generate new Status Bits For the signals coming from the C8k audio busses, you can decide
whether the AES Channel Status Bits are taken from their source or if
you want to generate new ones.
In this case the Channel Status will be set to:
Format : Professional
Audio Mode : Audio
Emphasis : None
Freq. Mode : Locked
Sample Freq. : 48kHz
Channel Mode : Not Indicated
User Bits : None
Auxiliary Bits : 24Bit
Audio Word Length : Not indicated
VANC Metadata the VAC Dolby Metadata embedder allows you to embed two
independent Metadata streams C and D. You may assign each stream
an independent SDID (see page 9 for details). The Metadata to be
embedded are extracted from the User Bits of the audio data received
by the respective c8k audio busses.
You can select a line where the Metadata must be embedded or you
can leave it in “auto” mode. In this case the next possible line that has
nothing embedded will be selected.
