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.

ViBE

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.

REGIONAL HEADEND – GENERATE MORE REVENUE

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.
