Thomson Video Networks New NetProcessor 9030/40:
The Heart of the Digital Headend
September 10, 2010
Thomson Video Networks
(formerly the digital headend division of Grass Valley) has
announced the NetProcessor 9030/40, a new addition to the
market-leading NetProcessor family, and a key component in
Thomson's complete solution for the digital headend.
The NetProcessor 9030/40 is a dense multiplexer and advanced
video processor designed to sit at the heart of any video
compression system for preparing and delivering content over
The DVB-T2 ready NetProcessor 9030/40 combines
the multiplexing and advanced service information handling
of the 9030 with the 9040's video processing capabilities,
including splicing and transrating for regionalization/insertion.
The NetProcessor family now features a streamlined architecture
designed for easy upgrades when customers want to expand the
functionality of their NetProcessor unit.
With the industry's most efficient multiplexing
algorithm, the NetProcessor 9030/40 combines and packs hundreds
of services into transport streams with an unequalled 0.04
percent overhead allowing costly spectrum to be used
to its maximum capacity. This industry-leading performance
is achieved by the NetProcessor's advanced service and bitrate
policing of incoming transport streams, combined with fully
adaptive playout of Service Information.
Service Information (PSI/SI/PSIP) is notoriously bursty by
nature and often requires costly overhead buffering, reducing
available bandwidth for the encoders. With its highly efficient
and fully adaptive SI playout engine the NetProcessor 9030/40
optimizes this stream, increasing the bandwidth utilization
and enabling increased picture quality.
As part of the complete digital headend
solution from Thomson Video Networks, the NetProcessor 9030/40
can also be enabled with patented Flextream technology,
making the unit the bandwidth manager when multiple ViBE encoders
are operating together in a statistical multiplexing pool.
Flextream is uniquely capable of combining any MPEG-2/4 and
HD/SD streams to harvest the maximum bandwidth when combining
multiple streams of varying complexity, and boosts transponder
throughput by up to 30 percent.
With Flextream enabled, the NetProcessor 9030/40 can manage
both local and geographically distributed encoders, allowing
broadcasters to save on both incoming and outgoing bandwidth,
whilst preserving outstanding picture quality.
The Thomson NetProcessor 9030/40 is a versatile
unit situated at the heart of the digital headend. It provides
exceptional processing power and scalable features, which
help broadcasters seamlessly expand their operations, simplifying
such tasks as adding a new transponder or inserting local
programming. When fully configured, the 9030/40 offers the
most complete set of video processing functions, including
re-multiplexing, PSI/SI processing, transrating, splicing,
data injection, ad insertion, and the scrambling of hundreds
"Since its launch, the NetProcessor
9030/40 has established itself as the market-leading MUX and
stream processing product for the headend," said Christophe
Delahousse, president, Thomson Video Networks. "The outstanding
versatility and wide range of features offered by the new
NetProcessor 9030/40 make it the keystone of Thomson's end-to-end
offering for the digital headend the most comprehensive
solution available to today's broadcasters."
The NetProcessor 9030/40 is housed in a
compact 1RU chassis and can generate six independent, densely
packed and fully compliant MPEG transport streams from up
to 1,000 incoming services, reducing the footprint and power
consumption of the operator's headend infrastructure.
The NetProcessor 9030/40 features dual hot-swappable power
supplies for maximum uptime, with the ability operate with
a redundant spare unit as part of an overall system.
