Output Attenuation
This control can be used to make minor adjustments to the output
power level, but in normal operation should be disregarded.
Video Input
This control is used to select the composite video input standard.
Options are PAL, and NTSC both with and without 7.5 IRE pedestal.
The licensed SDI digital video input can also be selected.
MPEG Mode
The default encoding mode is MPEG2, however for SOLO4 products if
the Ultra Narrow Band upgrade has been purchased, then MPEG4 will
also be available. It is recommended that MPEG4 be employed when
the unit is operating at low bitrates (2.5MHz bandwidth FEC1/3 or
1.25MHz bandwidth FEC1/3).
MPEG2 GOP Length
By default MPEG2 GOP length is set to a low delay stripe refresh mode.
This option allows the user to set the GOP length for a standard GOP
structure at the expensive of an additional delay.
MPEG4 Encoding Mode
This option is only available on SOLO4 products installed with the Ultra
Narrow Band Upgrade. This defaults to low delay interlace. Other
modes are available but advice should be sought from domo before
selection.
MPEG4 Frame Rate
This option is only available on SOLO4 products installed with the Ultra
Narrow Band Upgrade. This option allows the user to select lower
frame rate encoding (1/2 frame rate, ¼, 1/8 etc) It is recommended that
MPEG4 reduced frame rates be employed when the unit is operating at
low bitrates (1.25MHz bandwidth FEC1/3).
Video Bitrate
This control can be used to set the video bitrate within the constraints of
capacity available in the channel, but only when “Chaining Input” is set
to ON.
When the Manual radio button is enabled, the user can manually set a
video bitrate upto the maximum value. When manual bitrate is selected,
the user is in control of the video bitrate, this can be usefull when
configuring chaining systems.
