Introduction
NewS
tream is a rack-mounted microwave van transmit system designed to combine
transmission technologies into a single 2 RU chassis platform. It is designed to make
the gathering and transmission of news events a seamless and comprehensible task.
NewStream offers multi-mode operations which can include:
• ENG [Electronic News Gathering]
• SNG [Satellite News Gathering (Upgrade Option)]
• CNG [Cellular News Gathering (Upgrade Option)]
The LiveGear Receiver [LGR-1000] is a playout device that receives NewStream IP
transmissions via the Internet and provides an HD/SD-SDI output. Up to six New-
Stream transmitters can be received simultaneously using one LiveGear Receiver.
You can also use the VMS-1100 video media server to transcode the IP transport
stream from the LiveGear Receiver for delivery to laptops, desktops, smartphones and
tablets.
Advanced Vislink algorithms provide effi cient, robust, and persistent video transmissions
of unmatched quality. NewStream aggregates multiple 3G/4G LTE cellular channels
and optimizes data throughput. This mobile unit delivers consistently smooth and
dependable pictures and sound despite the occasional cellular traffi c surge or spotty
signal.
Leading-edge H.264 adaptive bitrate encoding technology provides remarkable video
resolution with minimal latency.
NewStream transmits at approximately half of the data
rate required by MPEG-2 based systems. Lost or stalled data packets are seamlessly
compensated for with Vislink’s exclusive predictive forward error correction algorithms.
This feature provides unparalleled signal integrity throughout your entire event
coverage.
