5.5.3.3.3 Splicing Stream Configuration
Splicing
The following parameters are available on the Splicing tab of the Properties widget on the
Service Configuration page when an SCTE 35 stream is selected in the Outputs widget.
The same parameters can be accessed through the Advanced/CE-x/Video/Video
1/Video/Main Video/Splicing menu on the front panel.

Description
Indicates the required level reduction of the center channel
when mixed with the L& R channels for a Lo/Ro downmix.
When present this replaces the value set for the 'Center
mix level'
Indicates the required level reduction of the center channel
when mixed for Lo/Ro downmix. When present this
replaces the value set for the 'Surround mix level'.
Flags if the stream has been encoded in Surround Ex.
Only used if surround channels are present.
Indicates type of A/D conversion used.
To meet the Dolby Digital encoding algorithm specification
the audio must not have pre-emphasis applied. If the input
signal does have pre-emphasis applied, a de-emphasis
filter must be applied prior to encoding.
Removing the DC component can lead to more efficient
encoding, but there is a risk that signals that do not reach
100% PCM may exceed this after filtering and therefore
must be clipped.
Remove high frequency signals before encoding. The filter
removes frequencies that would not normally be encoded.
Apply a 120 Hz low pass filter prior to an encode. Should
only be switched off if it is known that there are no
frequencies above 120 Hz.
Attenuate surround channels by 3 dB before encoding.
Theatrical and consumer mixing rooms use different levels
for the surround channels, and this can be used to
compensate.
Apply a phase shift of 90 degrees to the surround
channels. This simplifies the decode process for producing
a 'Lt/Rt' downmix.
Description
Enables splice points to be set in the video stream upon
reception of a SCTE 104 message and determines the
insertion point.
To enable splicing, a splice point insertion license
(CE/SWO/DPI) is needed.
Used to determine the insertion of NULL SCTE 35
messages into the output stream if no messages have
been sent for 500ms.
Used to determine if audio is manipulated at the point that
the video splice occurs.
