NewStream User Guide and Technical Manual
From a cost savings standpoint, it is judicious to set the maximum video encoding
data rate to the lowest level required to support the kind of video being produced. In
addition,
NewStream’s adaptive bit rate encoding technology automatically reduces the
encoding data rate based upon the degree of motion detected, to further enhance data
usage conservation.
Satellite [SNG] Operation
NewStream’s satellite system allows you to transmit using your existing equipment.
Your Block Up-converter [BUC] is used in the transmission [uplink] of satellite signals. It
converts a band of frequencies from a lower frequency to a higher frequency. There are
three frequency tuning options in satellite mode: Frequency Tuning in L-Band [Block-
upconverter disabled], Frequency Tuning with BUC enabled in Ka, Ku and C bands
and with either High or Low side local oscillators. Additionally, you can set up preset
frequencies in Remote control categorized by specifi c channels [Channel tuning].
SNG functionality allows user-defi nable frequency and power level confi guration. SNG
modes have fi ne control of frequencies down to 1 KHz gradations and power outputs
down to 0.1 dB gradations. To facilitate this, the up/down/left/right and enter buttons to
allow you to easily select frequency and power level in local control on the front panel.
As mentioned for Microwave and Cellular control, set the IDU to Remote Mode and
go to the Modify Presets Web interface to make unique copies of the SNG Presets in
order to create customized presets that your operators will use during broadcast. For
more information refer to the
Modify Presets section. For Remote Control operation
see the sections below:

In SNG mode, the three OLED buttons on the right [Figure 5 items K and L] are not
used for antenna control. Instead, they have been re-purposed for the Left and Right
movement as arrow buttons.
Touchscreen Display for SNG Operation
SNG Sub-menu
When in Satellite Mode, the touchscreen replaces the ODU sub-menu with an SNG
sub-menu. Under this sub-menu the following information is displayed:
o
Channel Plan Mode or Frequency Tune Mode selection
• You can select either Channel Plan Mode or Frequency tune mode via this sub-
menu.
o
Block Up-converter [BUC] LO Frequency - button in the BUC Setup touchscreen
• Spectrum Non-Inverted or Spectrum Inverted Selection underneath BUC
Power Level Selection
The section that previously showed ENG power level is replaced with a section that
shows SNG power output from the NewStream . This section also allows you to set a
power level between -40.0dBm and +5.0dBm with resolution up to 0.1 dBm.
