5.5.3.5.3 Splicing Stream Configuration
Splicing
The parameters listed in the table below 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-HEVC/Video/Video 1/Video/Main Video/Splicing menu on the front
panel.

Description
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
On VANC Message only does not insert splice point, but
converts the SCTE 104 message to SCTE 35 message in
the output.
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.
