Higher-quality encoding at lower bit rates
for the demanding broadcast industry
eNV SD Encoders
Highlights
A family of single-chip encoders
that utilizes a common platform
Integrated resizing and noise
reduction ltering options
produce higher-quality video
at lower bit rates
Single memory interface
provides critical board space
savings, and reduces overall
board design complexity
Packetized Elementary Stream
(PES) output support helps
simplify video timestamping and
A/V synchronization functions
World-class technical support
helps make system design, test,
and deployment more efcient
Better Performance, Higher Quality,
Greater Flexibility
The IBM eNV SD MPEG-2 video
encoders are the latest in a long
line of high-quality MPEG com-
pression solutions designed to meet
the exacting needs of professional
video encoding applications. If
you’re developing applications to
meet these needs — such as video
servers or editing systems, broad-
cast head end, or DVD authoring
systems — eNV SD encoders will
help you produce high-quality
compressed video at low bit rates,
while reducing overall system expense.
With a common hardware platform and
signicantly more feature integration
compared to previous-generation
encoders, the eNV SD helps simplify
board and system designs. IBM
worldwide technical support makes
integrating the eNV SD encoders
into your design easier.
