Chapter 1
Introduction
Ellipse 3000 contribution encoders leverage Harmonic’s industry-leading compression expertise
and
a flexible system architecture to bring new levels of video quality and work flow efficiency to
broadcast contribution applications. Multi-format, multi-codec versatility, low latency and an
optional integrated modulator make this all-new compression platform ideal for both digital
satellite news gathering (DSNG) and fixed contribution. A compact footprint and plug-and-play
deployment deliver the additional benefit
of low cost of ownership.

1.1 Operating
Environment
Ellipse 3000 encoders support all SD and HD MPEG-2 and MPEG-4 AVC codecs at 4:2:0 or 4:2:2
chroma
sub-sampling and 8 or 10-bits. Fully firmware upgradeable, the encoders offer a smooth
and cost-effective migration path from MPEG-2 SD 4:2:0 8-bit to AVC HD 4:2:2 10-bit compression
schemes, making them among the most versatile contribution encoders available. Options for re-
multiplexing and cascading allow
the devices to operate on a stand-alone basis with no need for
external multiplexers or PSI generators.

–
For fixed contribution over IP networks; featuring simultaneous IP and DVB-ASI
outputs
. The Ellipse 3100 Contribution Encoder enables a smooth and cost effective migration
path from MPEG-2 CBR to MPEG-4 AVC (H.264) CBR concurrent encoding schemes for Standard
Definition (SD) media encoding. The Ellipse 3100 is a state-of-the-art unit, featuring low-delay
mode and cascading capabilities in addition to broadcast video quality. The Ellipse 3100
Contribution Encoder enables MPEG-4 AVC (H.264) HD media encoding.
■
