System Description
The NewStream compact video transmitter system provides reliable and fl exible
microwave modulation, Cellular/Wi-Fi and MPEG2,/H.264 encoding functions. The
NewStream system includes an Indoor Unit [IDU] consisting of the 19-inch wide, 2-rack
unit [2RU] high, rack-mounted transmitter, as shown in Figure 3, and a mast-mounted
Microwave Outdoor Unit [ODU] or RF Unit [RFU]. The ODU is also known as an RF
head and/or Cellular Outdoor Unit [C-ODU] on-roof mounted units.
The NewStream IDU is typically mounted in a standard 19-inch [48.3 cm] rack for
mobile installations and the ODU is mounted on an antenna mast. The IDU contains the
baseband circuitry, power supply and control modules. It accepts a wide variety of audio
and video inputs, both analog and digital and generates a 70 MHz IF for legacy heads
and 950 MHz IF for NewStream heads.
The IDU can be locally controlled from its front panel or remotely from a PC, tablet or
smartphone over an IP connection using the NewStream’s Web browser graphical user
interface [GUI].
The IDU directs overall system control such as video encoding, modulation and power
distribution. The
NewStream transmitter supports Cellular video streaming, MPEG2 HD
and SD encoding, H.264 HD/SD encoding, AES/EBU and Analog audio, ASI input and
output, as well as various modulations and rates.

The NewStream transmitter system [ENG] supports both single and dual band
operation. The IDU can interact with legacy MTX ODUs or new improved performance
NewStream ODUs which can be single or dual band in the same ODU housing.
NewStream is a video transmission system with digital modulation capabilities which
provides a sophisticated user interface with an adjustable color LCD display panel
with touch screen control. An analogous Web interface enables remote control of the
system.
