functionality for primary and
secondary distribution architectures.
The solution can be integrated with
the Appear TV XC5000 Series Video
Chassis to provide users with a
complete, integrated solution with a
uniﬁed open standard user interface
that can support all broadcast
processes, eliminating the need
for different encoding systems
for the distribution of live TV over
cable, IP, satellite, terrestrial, OTT
and multiscreen. This solution works
through building 'pools' of encoding
and transcoding resources catering
for multiple synchronised video
stream proﬁles from any source in
any format for distribution to HD
TVs, computers and mobile devices.
The platform provides excellent
channel density, dual-pass
compression with exceptional
rate decision coding algorithms
to provide exceptional video
quality for AVC and MPEG2 SD/
HD, making it ideal for the primary
distribution of live broadcast
content where guaranteed quality
is a prerequisite. To ensure that it
meets this performance benchmark,
it can be packaged with the new

statistical multiplexing software
sporting a second generation multipass look-ahead architecture with a
rapid refresh rate.
The unique modular nature of the
video processing platform allows
broadcast, cable, satellite and
telecom providers to select from
multiple modules to create a solution
custom-tailored to their needs.
Modules can be mixed and matched,
providing decoding, decryption,
descrambling, transcoding and
encoding functionality to enable the
distribution of content to all screens
and with the capability to adapt, edit
and process the PSI/SI data and
provide modulation and high-end
IP functionality for a wide range of
network types simultaneously.
It is clear that hardware encoding
is the natural choice for operators
who want to provide the highest
possible picture quality while
ensuring that costs, QoS parameters
and complexity can be signiﬁcantly
reduced. We firmly believe that
hardware encoding is the best
choice for some time to come, due
to its advanced ﬂexibility, latency
and picture quality.
