Media Gateway:
Live Media Transcoding and

enterprise, not least in the electronic
media industry. The Channel-in-aBox
concept which we have refined
over nearly a quarter century gives
television broadcasters the freedom
to
perform
the
entire
station
management process in a single
server occupying just 1U of rack space
and controllable from any securely
connected desktop PC.
Ingest, editing, finessing, graphics
creation, scheduling, presentation
and playout can be performed with
any desired level of automation plus
the ability to transmit live whenever
required. System expansion is as
easy as adding extra CIAB units or
easier still via our Cloud2TV solution
or a hybrid
of
server-based and
service-based channel management.

Incoming uncompressed
content
can also, or alternatively, be routed
to Media Gateway's internal transport
stream encoders for distribution in
compressed data formats such as
UDP, RTP, SRT and/or Zixi Push. The
middle and lower sections of the
workflow diagram show these tools.
Individual streams can be timeoffset
by up to several days via
the TS Delay option, the maximum
delay depending on the amount of
attached storage. Integral software
codecs allow signals to be converted
between SDI, NDI, SRT, UDP and
RTP. Video and audio content can
be sourced directly from a desktop
screen and delivered as
live feeds. The channel

to switch multiple streams

destinations. This allows
switching of
