Digital Terrestrial Television Headend Solutions
DVB-T/T2DVB-T/T2
Thomson Video Networks offers a comprehensive solution for digital terrestrial television including broadcast multiplex generation, regionalization, and distribution, plus our latest addition – support for broadband services in hybrid HbbTV 1.5 services headends.
Superior Picture Quality
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 bitrates in large statmux
pools to high-quality SD and 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 Networks
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 Quality of Service (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 bitrates,
MPEG services, telecom, and RF
transmission.

Video Compression
Because DTTV operators’ primary
concern is to use every kbps of their
bandwidth to the fullest in the national
headend, our ViBE EM series of SD and
HD encoders have been designed to
fulfill this requirement. Leveraging our
Mustang compression technology, the
ViBE encoder combines compression
efficiency and advanced preprocessing
to deliver pictures of outstanding
sharpness, 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 bitrates, e.g. up to eight HD services
in a DVB-T/T2 multiplex. 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 2.0: Statistical Multiplexing
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.
It also features support for remote
encoding pools, removing contribution
codecs and bandwidth costs, leading to
better quality at a lower cost.
With Flextream 2.0, our advanced
statmux solution subtitling and data
component are now dynamically
included in the statmux. There is no
need to provision static bandwidth
for teletext, subtitling, EMMs, HbbTV
interactive services. Flextream 2.0
solution has two major advantages – the
null packet bitrate at the TS output is kept
to a minimum, and headend operations
are greatly simplified as multiplexer
reconfiguration is rarely required.
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 XMS/XMU or the NetProcessor 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, using advanced DVB-
SI capabilities such as triggering, automatic
bandwidth management, multi-route
capabilities. When coupled with the Coral
iTV broadcasting server or the HbbTV
carousel server, it forms a complete data
solution that can be leveraged by third-
party applications such as OpenTV, MHP,
and HbbTV.
SFN Adaptation – DVB-T2 Gateway
Single Frequency Network (SFN)
adaptation is performed within the
NetProcessor multiplexer. 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
up to four T2-MI streams over IP or ASI.
HbbTV Broadband Linear Services
Combined with the ViBE VS7000 multi-
screen encoding solution, the DTTV
headend can deliver additional linear TV
services over the internet to TV sets and
mobile devices. Please refer to the Multi-
Screen Video brochure for more details.

NetProcessor: the DVB-T/T2 Toolbox
In the regional headend, the
NetProcessor performs network
adaptation (ASI, IP, PDH, SDH, ATM),
decapsulates the T2-MI streams, performs
remultiplexing, PSI/SI processing,
scrambling, seamless switching from/to
local live content and local advertising
clips, scrambling, SFN and DVB-T2
adaptation.
Cost-effective Regionalization
This technology is to build a statmux
pool with the national services and the
regional services, all regional service
encoders being driven by the same
bitrate allocation computed from all
complexity inputs. Flextream 2.0 benefits
are full VBR quality for the optimum cost
of one encoder per regional.
24/7 Local Insertion
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.
Live to Live Seamless 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). Thanks to Flextream 2.0 technology,
the splicing is performed within a
VBR pool without transrating or over
provisionning null packets.
Advertising Insertion
Ad insertion increases revenues
through regional customization while
minimizing costs. Thomson Video
Networks’ 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 MPEG stream server (ingest
and ad server), ViBE encoders, and
NetProcessor for seamless splicing.
Flextream 2.0 allows ad insertion within
a VBR pool without transrating or over
provisioning null packets.
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.

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 RD1000 demodulator/descrambler
transparently and accurately filters and
delivers the original transport streams
to the transmitter for both SFN and MFN
networks.
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

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 III
switch 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.
