Achieving the best picture quality at the lowest bit-rate enables
operators to broadcast more channels in their available bandwidth over
digital cable, satellite and terrestrial networks - maximising return on
investment of this valuable resource. For broadband operators offering
TV services over xDSL networks, achieving the lowest bit-rate can
provide multiple simultaneous services into the home, or be used to
extend the loop length over which TV services can be carried from the
DSLAM to the consumers home - maximising return on network investment.
TANDBERG Television has always led the market in provide encoding
platforms that give optimum quality at the very lowest possible
bit-rates. The EN5990 combines the sophisticated MPEG-4 AVC video and
latest audio compression algorithms with the TANDBERG High Definition
Intelligent Compression Engine (HD-ICE). A dedicated hardware and
software implementation, based on over 10 years in-house experience of
creating high performance real-time encoders.
Market Leading Performance
Extensive video pre-processing helps get the best picture, whatever
the source. A proven history of providing customers with in-field
performance improvement upgrades over time, keeps our customers ahead
of the market.
Reliable Service Delivery for any Application
Designed with all the proven system interconnect and control that
our MPEG-2 product range enjoys today. In combination with the rest of
the TANDBERG Television product range this makes MPEG-4 AVC deployable
today in any broadcast or broadband application.
Advanced Features for IPTV
Options for encoding of a low resolution, low bit-rate simultaneous
Picture-in-Picture (PIP) service, and direct IP multicasting from the
encoder enable the EN5990 to be deployed in any IP distribution or TV
over xDSL application.
Variable Bit-Rate Operation Modes
Option for standalone variable bit-rate operation allow IPTV
operators to maximize picture quality while harvesting capacity for
Internet data traffic delivery to the home. Option for Reflex™
statistical multiplexing enable satellite, cable and terrestrial
operators to maximize picture quality using bit-rate sharing
