E5780 / E5782 HD Encoders
HDTV allows broadcasters to differentiate themselves with high
quality programming and an enhanced viewing experience. The higher
bit-rates required for HDTV mean that broadcasters require the best
possible encoding solution to make best use of available bandwidth over
digital cable, satellite and terrestrial networks - maximising return on
investment of this valuable resource.
Offering both standard definition (SD) and high definition (HD)
encoding modes, the E5780 is ideal for professional ATSC and DVB
broadcasters. It is able to encode at multiple profiles in both modes
and the E5782 also supports HD 4:2:2 for HD contribution and digital
cinema applications. The E5780's SD mode allows a single E5780 to act as
the only spare in a mixed SD and HD system. Support for Multi-Pass
encoding allows the E5780 to deliver the best possible quality using
statistical multiplexing and allows the mixing of SD and HD encoders in
a single statistical multiplexer maximum efficiency.

E5780/E5782 Encoders Overview
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 improvements and feature upgrades, keeps our customers
ahead of the market.
Appropriate for a Wide Range of Applications
The E5780 and E5782 are easily adaptable to a wide range of
professional applications that require top-level performance and
functionality. The 2RU chassis allows up to 4 option cards to be
fitted and supports a 12 key alphanumeric key pad, 8 hot keys and
video input confidence monitor. The low-bit rate performance makes the
E5780 an ideal component in any HD DTH platform.
The E5782 adds support for HD 4:2:2 encoding which, when combined
with the maximum bit-rate of 90 Mbit/s, make the E5782 idea for the
highest quality contribution links and for HD cinema applications.
Variable Bit-Rate Operation Modes
Option for standalone variable bitrate operation allows operators
to maximize picture quality while harvesting opportunistic data.
Option for Reflex™ statistical multiplexing enable satellite,
cable and terrestrial operators to maximize picture quality using
bitrate sharing techniques. The E5780 supports mixed SD and HD
statistical multiplexing systems including Multi-Pass statistical
multiplexing.
