Digital Terrestrial Television - An Overview

29 November - 1 December 2010

Transmitter Picture KH1Course Overview

Speakers drawn from a number of organisations directly involved in the implementation of the world's first commercial DVB-based Digital Terrestrial Television (DTT) system will give a practical introduction to the design of DVB DTT systems.

The course includes a visit to National Grid's Transmitter site at Guildford - weather permitting!. If wet weather is predicted, walking shoes or boots are advisable as the site can get muddy!

A large range of material is covered over the three days of this course and it is intended to give a general overview rather than go into a great deal of detail. 

The course will suit engineers with a reasonable knowledge of general television broadcasting principles.

The course has proved very popular over the last four years and around 200 TV engineers have attended this course. The course is constantly updated to meet the changing trends and technologies in the Television Industry.

Please note that we are also running a course on High Definition Television (HDTV) week of 6th December 2010

Who should attend?

The course is aimed at those who need an overview of Digital Terrestrial Television, and is firmly based on practical experience gained in the UK. Topics will include:

•  UK regulatory position •  Receiver hardware and software
•  MPEG-2 encoding •  Conditional access
•  DVB transport streams •  Case study
•  OFDM modulation •  Monitoring and measurements



Setting the scene: Licensing in the UK, technical standards, analogue switch-off, review of international DTT roll-out

Video and audio coding: The need for compression, MPEG-2 profiles and levels, basic compression techniques, typical encoder architecture, bit rates for picture and sound quality targets, bitstream statistics, concatenation, new compression algorithms.

The DVB Transport Stream: SI, PSI, EPGs, data broadcasting, data carousels, private data, opportunistic data.

Channel coding and modulation: Coded Orthogonal Frequency Division Multiplex, the DVB-T specification, how it is implemented, effects of multipath, mobile applications, multi-frequency networks (MFN), single frequency networks (SFN), comparison with the US standard (8-VSB). •  Reception: receiver RF performance, individual domestic reception, Master Antenna (MATV) reception, Integrated Reception Systems (IRS)

Receivers: hardware architecture, common interface, receiver software, interactive TV, MHEG-5, DVB MHP.

Conditional access: Business model enforcement, EMMs and ECMs, smart cards, Simulcrypt, subscriber management, anti-piracy measures.

Case study: programme distribution & multiplexing, schedule distribution and collation, central and distributed SI.

Bitstream monitoring and measurements, in-service and out-of-service video quality measurement techniques and systems.

Visit to the Guildford transmitter.

Transmitters: redundancy switching, effects of transmitter non-linearity, practical filter and combiner implementations. Measurements: phase noise, loss of noise margin, modulation error ratios. Control and monitoring techniques.

The Lecturers

Peter Barnett
Peter Barnett, CEng, MIEE, has over 27 years of experience of broadcast transmission technology, and runs his own consultancy company, Mandercom Limited. He is chairman of the UK Digital Television Group’s Technical Steering Group, Technical Plenary, and Reception Group. For over seven years he has contributed to the DVB Technical Module, and he attends the DVB Steering Board and Commercial Module.

Peter Lewis
Peter Lewis, CEng, MIEE, is a Specialist in DVB Receiver Systems at Philips Semiconductors Systems Laboratory in Southampton, UK. He has worked for the Philips organisation since 1969. He started at their research laboratories in Redhill, where he worked on Automatic Aerial Tuning (HF), Aerial Beam Steering (VHF), and finally TV Transmitter Precorrection (UHF). He then moved to Philips Semiconductors, and has since specialised in TV receiver systems.


Keith Hayler
Keith Hayler, CEng, MIEE, is Principal Technologist with Arqiva (formerly with National Grid Wireless). With over 30 years experience in a wide range of broadcast transmission technologies, he has worked in the development of DTT networks since their inception. Keith played a key role for Crown Castle as technical manager in the roll-out of UK DTT in the late 90's and the re-launch as Freeview in 2002.

Alois Bock
Alois Bock, Dipl.Ing.(FH), PhD, MIEE, is a Senior Member of Technical Staff at TANDBERG Television. He has worked on both algorithmic development and hardware implementation of MPEG compression and transport stream processing equipment including video pre-processing, motion estimation and transport
stream splicing.


Greg Bensberg – Principal Advisor - Broadcasting

Greg Bensberg currently works for Ofcom and is Project Director of Ofcom’s Digital Dividend Review project which is examining the options arising from the release of spectrum afforded by digital switchover. He also leads the technical planning work for digital switchover is currently Chairman of the Joint Planning Project (which plans and allocates spectrum for UK DTT services). Greg Bensberg has previously worked for a variety of organisations including the ITC (1992 – 2004), Thames Television, Quantel and Marconi Communications. He has been involved in all elements of digital broadcasting including leading the Spectre Project which mounted the first UK trials of Digital Terrestrial Television in the early 90's, the development of the DVB transmission standard, the licensing of DTT services by the ITC in 1996 and 2002 (Freeview) and the development of the UK’s digital switchover strategy (when he was seconded to the government’s digital television action plan).
