Ericsson E5750 Voyager Digital ENG System
Broadcasters and news gathering organizations want pictures from anywhere in the world, live, and at an instant.
Increasingly, they are looking to mobile microwave links to cover news events in places where using satellite is
difficult, such as in the world’s largest cities, or where satellite is too slow or expensive, as during natural disasters or
fast-breaking events. New technology includes digital COFDM systems, which have rapidly replaced analog
transmission because they are fast to set-up, more efficient and don’t have point-to-point link limitations. The
Ericsson E5750 Voyager Digital ENG system is designed for this market, offering robust, long-range DENG
transmission with outstanding MPEG-2 encoding, highest picture quality and a flexible array of options.
Sample Configuration
The E5750 is available in 4:2:0 and 4:2:2 encoding versions in a 2RU
chassis, offering a complete range of quality options including ultra
high-performance encoding for special events. The encoder also supports
a range of low-latency modes to reduce encoding delay, and can be
upgraded to MPEG-2 high definition (HD) or MPEG-4 AVC (SD and HD) with
option cards.
Ericsson can configure the E5750 with a DVB-S2 modulator card along with the COFDM modulator, providing a
dual-purpose DENG/DSNG system for maximum flexibility and convenience. The unit supports all of the major DVB-T
modes and can support RF output with the addition of a RF up-converter card. Ericsson’s extensive video
pre-processing combined with advanced encoding techniques provides superior picture quality and a longer
|transmission range over the COFDM link.
Product Overview
Dual Purpose DENG and DSNG Platform
The E5750 with an integrated COFDM modulator can also be
equipped with a DVB-S2 modulator, which can provide up to 35%
bandwidth savings for satellite applications. This provides a highly
flexible dual-purpose platform for
newsgathering operations, allowing
news teams to decide the best method for delivery based on their
needs at any given time.
Upgrade Paths to High Definition
The E5750 can be upgraded to provide either MPEG-2 HD or
MPEG-4 AVC HD and SD. The ability to provide MPEG-2 is retained
in both cases. Our MPEG-4 HD option has proven to be of great value
to those finding that using MPEG-2 HD increases bitrate too much,
causing transmission range and stability problems that using MPEG-4
HD solves.
D.C. Power and Remote Control Support for External
Up-converters
ENG delivery can require additional amplification and external RF
frequency conversion. The E5750 can support a TRIAX option card
for transferring the modulated IF signal over large distances. The card
provides DC power (+48V) to support an external, integrated
up-converter and power amplifier for all established DENG frequency
bands. For shorter cable distances between the DENG equipment
and the TX antenna an internal RF up-converter card can be used
|
Highly Flexible DENG Platform
The E5750 is easily adaptable from fast-paced newsgathering to
concerts and high-quality sporting events with its 4:2:0 and 4:2:2
encoding capabilities. The 2RU chassis allows up to five option cards,
which enables a highly customized solution. Options include MPEG-2
HD or MPEG-4 AVC HD/SD encoding formats for lower bitrate, higher
quality delivery. TANDBERG Television's powerful REMUX option
card provides MPEG multiplexer and multi-channel MCPC capability.
