Thomson Video Networks offers a global solution for digital terrestrial television including multiplex generation, customization, and distribution, combined with management and quality of service monitoring.
Delivering Innovative Services
Delivering a large channel bouquet,
including HD, puts constraints on the
compression engine. At the same
time, video quality has become more
important with larger consumer screen
sizes aimed at HD content and Blu-ray
players. Thomson Video Networks has a
tradition for delivering premium video
compression through the ViBE family,
from ultra-low bit rates in large statmux
pools to high-quality HD content. Our
philosophy is to deliver premium picture
quality for all networks.
Powerful Content Processing
As content is increasing in value and
distributed across multiple networks,
content processing is increasingly
important. As different networks have
varying characteristics, content needs
further adaptation, including 24/7 local
channel insertion, seamless national /
local channel switch, and advertising
regionalization. In addition, interactive
services and electronic program guide
(EPG) scheduling and insertion are fully
integrated. Thomson Video Networ ks
is the only provider able to combine all
of these features in a fully integrated
headend to suit all networks.
End-to-End Management
Equipment management and redundancy
scheduling is critical to achieve reliability.
Thomson XMS™ control and monitoring
with QOS logging and the support
of remote probes provides increased
freedom and flexibility, while offering a
suite of applications and graphical user
interfaces for controlling operational
parameters such as bit rates, MPEG
services, telecom, and RF transmission.
Video Compression
Our ViBE EMx000 line of encoders for
standard- and high-definition (SD and
HD) video delivers MPEG-4 AVC and
MPEG-2 compression. Leveraging our
Mustang video compression architecture,
ViBE combines compression efficiency
and advanced preprocessing to deliver
clearer pictures with increased depth
and clarity. With the ability to use all
available compression toolsets, including
true High Profile, our MPEG encoders
let you broadcast high-quality SD
and HD content at very low bit rates.
With integrated Dolby Digital Plus 5.1
surround sound generation or the latest
AAC audio codec, you can deliver audio
that matches the high quality of your
video.
Flextream™: Statistical Multiplexing
Flextream statistical multiplexing is a
field proven solution for dynamically
sharing the fixed multiplex bandwidth
among multiple ViBE encoders with a
high degree of precision. This provides
an increase in the number of channels
offered by up to 30% versus using the
encoders in CBR mode.
Highly flexible, Flextream supports any
mix of SD and HD channels as well as
MPEG-2 and MPEG-4 compression.
Flextream also features support for
remote encoding pools, removing
contribution codecs and bandwidth
costs, leading to better quality at a lower
cost.
Support for Pay TV
Robust protection of revenue streams
and fine control of subscription-
based services with proper user rights
management is achieved by the Pay TV
solution. It’s based on the NetProcessor
as a DVB-Simulcrypt scrambler and the
XMU as the DVB-SC interface to the CAS
ECM generators.
This solution is open, supporting all
conditional access systems (CASs) on the
market. It’s powerful and scalable from
one to multiple CASs, running with large
numbers of ECM generators, delivering
a mix of pay TV and free-to-air services in
the same multiplex.
Adding Value with Datacasting
The Jade server can generate an
Electronic Program Guide (EPG) for
any kind of service architecture, small
or large, national or regional, using
advanced DVB-SI capabilities such
as triggering, automatic bandwidth
management, multi-route capabilities.
When coupled with the Coral iTV
broadcasting server, it forms a complete
EPG solution that can be leveraged
by third-party applications such as
MediaHighway, OpenTV, MHP, and
others.
SFN Adaptation – DVB-T2 Gateway
Single Frequency Network (SFN)
adaptation is performed within the
NetProcessor 9030/40 multiplexer so
there’s no need for external devices.
In the NetProcessor 1+1 / Amethyst
III switch redundancy scheme, the
mega-frames from the two units are
synchronized, thus avoiding transmitter
resynchronization on backup switchover.
The NetProcessor embeds the DVB-T2
gateway functionality, thereby delivering
T2-MI streams over IP or ASI.
From the output of the contribution devices (IRD, fibre, IP/ATM network adapters) to the output of the multiplexer, the primary concern is
the optimum use of the bandwidth for the best picture and audio quality.

NetProcessor 9030/ 40: The D TTV Toolbox
In many cases, the NetProcessor 9030/40
will be the only unit at the headend
location, addressing all of your needs
from basic remultiplexing up to live to
live regional switchover, performing
network adaptation (ASI, IP, PDH, SDH,
ATM, DVB-S/S2), MPEG processing
(descrambling, multiplexing, PSI/SI
processing, scrambling, SFN and DVB-T2
adaptation), and content processing
(seamless splicing and transrating)
simultaneously on multiple multiplexes.
Permanent Insertion of local Services
At the regional headends, the NetProcessor
contributes to multiplex customization by
adding content locally delivered by the
ViBE encoder and modifying the SI/PSI
information accordingly.
Seamless regional Switchover
This is a three-step process. First, from
the playout center the splice in and splice
out cue tone commands are sent to the
headend (SCTE104 over IP or SDI, analog
cue tone, GPI). Second, the encoder at
the headend translates the cue tones to
SCTE35 in-band commands. Third,
in the regions the NetProcessor uses
the SCTE35 commands to trigger the
seamless splicing between the national
and the regional channels (SD/HD, MPEG-
2/4).
Advertising Insertion
Ad insertion increases revenues through
regional customization while minimizing
costs. Thomson’s ad insertion solution is
based on digital program insertion (DPI)
within the compressed domain using
SCTE standards (SCTE30, SCTE35, and
SCTE104) in order to cover the complete
ad insertion chain. This gives you frame-
accurate ad clip ingest, clip distribution
to regions, playlist definition and
distribution, digital cue tone insertion at
the headend, seamless splicing for clip
substitution in region (SD/HD, MPEG-
2/4), and the generation of “as run” log
reports for billing. The key components
for ad insertion at the headend are the
Sapphire broadcast server (ingest and ad
server), ViBE encoders, and NetProcessor
9030/40 for seamless splicing.
local PSI/SI Processing
EPG service information can be built
centrally for multiple regions and filtered/
injected locally with the PSI/SI processing
power of the NetProcessor 9030/40.

Telecom Distribution to the Transmitters
The NetProcessor provides transport
and delivery of the multiplexes to the
transmitters transparently bit-accurate
whatever the medium (IP, PDH, SDH,
μwaves, and ATM) thanks to a large
range of interfaces, the network
impairment capabilities and SFN
alignment.
Satellite Transport
Concentration – The DVB-S2 multi-TS
feature offers a standard solution to
concentrate independent multiplexes
within the same satellite transponder.
The RD100x transparently and accurately
filters and delivers the original transport
streams to the transmitter for both SFN
and MFN networks.
optimized Multiplex regionalization
over S atellite Transport – On the
transmitter, the NetProcessor performs
SFN aware deterministic remultiplexing
from multiple satellite and local sources.
National services are only sent a single
time, leading to tremendous cost saving
by reducing the number of satellite
transponders required by a factor
ranging from 2:1 to 5:1.
Protection of the Free-to-Air Content
Transport – Free-to-air services must be
protected on the headend-to-satellite link.
Thomson Video Networks offers a range
of solutions for both SFN and MFN
networks to scramble at the source and
descramble before feeding the DTTV
transmitter: DVB BISS fixed key, DVB-SC

Command and Control
The XMS Management System controls
and monitors all Thomson compression,
MPEG processing, transmission
products, and number of third-party
products. In client-server architecture the
XMS offers a suite of applications and
graphical user interfaces for controlling
not just hardware, but also operational
parameters. With its NetOp client
application the XMS system provides a
clear view of an entire system, including
the fault-monitoring correlation of
affected services, MPEG rate monitoring
and audio plus video confidence
monitoring on a workstation. This view
allows supervisory staff to make the best
use of resources, and to accelerate fault
finding and resolution.
resiliency for Mission-Critical Systems
With redundancy at all stages of the
systems, the XMS plus the XMU
mediation device present a unique
design for a zero-fault system. The
proposed architecture supports
N+P redundancy for a pool of IRDs,
encoders, multiplexers, or modulators
in ASI and/ or IP infrastructures. For
1+1 redundancy schemes the Amethyst
switcher is a scalable and intelligent
device performing monitoring, delay
compensation and seamless switch of
multiplexes.
QoS Monitoring
The XMS performs live QOS monitoring
in any stage of the system, from the
central headend down to the transmitter
based on Granite MPEG-over-ASI/IP/RF
probes, a multi-layer MPEG monitor that
reports a transport stream’s health status
from the interfaces to the audio/video
levels. It monitors QOS in an easy-to-
understand manner, allowing non-MPEG
experts to make decisions and maximize
service availability.
