Parameter Values Description
Lt/Rt surround mix
level
0.841 (-1.5 dB), 0.707 (-3.0 dB), 0.595 (-4.5 dB),
0.500 (-6.0 dB), 0 (-inf dB)
Indicates the required level reduction of the surround
channels when mixed for a Lt/Rt downmix. Similar to
Surround mix level'.
Lo/Ro center mix level
0.841 (-1.5 dB), 0.707 (-3.0 dB), 0.595 (-4.5 dB),
0.500 (-6.0 dB), 0 (-inf dB)
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'
Lo/Ro surround mix
level
0.841 (-1.5 dB), 0.707 (-3.0 dB), 0.595 (-4.5 dB),
0.500 (-6.0 dB), 0 (-inf dB)
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'.
Dolby Surround EX
mode
0.841 (-1.5 dB), 0.707 (-3.0 dB), 0.595 (-4.5 dB),
0.500 (-6.0 dB), 0 (-inf dB)
Flags if the stream has been encoded in Surround Ex.
Only used if surround channels are present.
A/D converter type Standard, HDCD Indicates type of A/D conversion used.
Bandwidth low-pass
filter enable
Off, On
Remove high frequency signals before encoding. The filter
removes frequencies that would not normally be encoded.
Low-frequency effects
low pass filter enable
Off, On
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.
Surround attenuation
enable
Off, On
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.
Surround phase shift
enable
Off, On
Apply a phase shift of 90 degrees to the surround
channels. This simplifies the decode process for producing
a 'Lt/Rt' downmix.
5.5.3.1.3 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/EI9001/Video/Video
1/Video/Main Video/Splicing menu on the front panel.
Table 5.27 Splicing Parameters
Parameter Values Description
Splicing Control Off, On VANC Message Only, On VANC, On IP
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 (AVP/SWO/DPI) is needed.
Splice Null Insertion Off, On
Used to determine the insertion of NULL SCTE 35
messages into the output stream if no messages have
been sent for 500ms.
Audio Splicing Off, On
Used to determine if audio is manipulated at the point that
the video splice occurs.
