The Digital TV Group (DTG) is the independent industry association for digital television in the UK. The Group publishes and maintains the technical specification for the UK s Freeview and Freeview HD services (the D-Book) and runs the digital television industry s test centre: DTG Testing. Membership services Membership of the DTG is the only way to obtain the D-Book, the technical specification for UK digital terrestrial television (Freeview and Freeview HD) and hybrid broadcast/ broadband Connected TV services. Membership also provides access to draft versions of the specification before they are published while Principal, Full and New Entrant members can actively participate in the development of the specification through the DTG s working groups. The Group also provides the collective strength of over 150 member organisations to represent its membership at government and regulatory level and provides training, events, networking opportunities and market information that empower members to make informed business decisions. About the DTG The DTG was established by the UK digital television industry in 1995 to protect consumers and safeguard the reputations of distribution platforms and receiver manufacturers. Today the Group represents over 150 broadcasters, platforms, manufacturers, technology providers, government departments, regulators, not-for-profi t organisations and consumer groups. DTG Testing provides the test and conformance services for the UK s Digital Switchover Certification Mark (the Digital Tick ), the Freeview and Freesat services and international platforms. DTG Testing manages the Freeview and Freesat Engineering Channels which allows the transmission of software upgrades to receivers in the home. The test centre houses the UK s largest collection of receivers (over 95% coverage of the UK receiver population) on its premises for testing of new transmission modes and software downloads. The DTG allows Digital Europe to use areas of its copyright under licence to encourage international harmonisation. The Group represents its membership at government and regulatory level and provides expert consultancy for organisations entering the UK market or developing platforms internationally. In 2009, the Group published D-Book 6 paving the way for the consumer launch of high definition services on Freeview in early 2010. Following the publication of D-Book 6 the Group began to profile the specification for hybrid broadcast/ broadband Connected TV services which will be circulated to members as D-Book 7 in December 2010. The Group represents over 150 broadcasters, platforms, manufacturers, technology providers, government departments, regulators, notfor-profit organisations and consumer groups. 03

The D-Book The D-Book is the technical specification for UK digital terrestrial television (Freeview and Freeview HD). The DTG has published and maintained the D-Book for over a decade and the specification is updated annually to keep up with the pace of development in UK DTT. The D-Book is a living document and is continually enhanced and peer-reviewed by the DTG s expert working groups. The first edition of the D-Book was published in 1996 when the current UK standard for digital terrestrial broadcasting (DVB-T) was new and untried. Early editions of the D-Book enabled the publication of the European digital TV specification: the E-Book. In March 2009, the DTG published the 6th edition of the D-Book introducing DVB-T2, the new modulation scheme that is being used in the UK to deliver high definition services on DTT which enabled the consumer launch of an initial three free-to-air HD channels on Freeview in early 2010. D-Book 6 also mandated a broadband return path which can be used for streaming on-demand video content such as BBC iplayer, ITV Player and 4oD, accessing e-government services and allowing viewers to complete transactions via their television. The 7th edition of the D-Book will be circulated to members in December 2010 and contains the specification for UK hybrid broadcast/broadband Connected TV products and services. The D-Book is only available to members of the Digital TV Group. 05

Supporting the UK digital television market Our partners at the DTG continue to play an invaluable role in supporting the switchover programme, ensuring digital television equipment meets the high standards expected by industry, broadcasters and viewers. David Scott, Chief Executive, Digital UK Image: BBC Image: Arqiva Image: Arqiva D-Book 6 represents a landmark in UK broadcasting, providing the specifi cation for the launch of high defi nition services on Freeview. The DTG supports the digital switchover programme carried out by Digital UK. 06 Digital TV Group Setting the standards for the digital future

The DTG supports the digital switchover programme carried out by Digital UK. The Group s D-Book specification and test regimes underpin the Digital Switchover Certification Mark (the Digital Tick ) the logo used to tell consumers that a product is designed to work through digital switchover. DTG Testing conducts special switchover projects on behalf of Digital UK and the Department of Business, Innovation and Skills (BIS), using its receiver collection to simulate switchover scenarios in advance of regional switchovers and carries out spot tests of receivers carrying the Digital Tick to ensure they comply with the certification mark s requirements. The Group also provides a forum for Digital UK to engage with industry and to feed into technical requirements if required. DVB-T2 2009 saw the development of the 6th edition of the D-Book specification. D-Book 6 represents a landmark in UK broadcasting, providing the specification for the launch of high definition services on Freeview. The specification also includes a broad range of updates such as surround audio, HD interactivity, DVB-SSU, HD subtitles, an MHEG interaction channel and HDMI guidelines. To ensure market compliance the DTG provides the test and conformance regime for the Freeview and Freeview HD logos. Listening to our members One of the DTG s core objectives for 2010/11 is to increase the level of service we offer to members. The Group is committed to increasing membership value, driven by membership and customer consultation feedback and measured against a membership value index. To ensure we continue to closely monitor levels of membership and customer satisfaction, the DTG conducts an annual survey of DTG members and DTG Testing customers.

Shaping the future of digital In 2010, the DTG launched a consultation on how an interoperable, effi cient, stable and innovating horizontal digital TV market might best continue to be delivered. BSkyB is pleased to actively engage with the DTG in the development of an open standard for Connected TV devices. Nick Gregory, Business Development Director, BSkyB Virgin Media are committed to continuing their long-standing relationship with the DTG through the development of a core open standard for UK Connected TV. Ian Mecklenburgh, Director, Digital Entertainment, Virgin Media Indicative YouView interface All YouView compliant devices will meet D-Book 7 standard. Sky Player D-Book 7 will provide a common specifi cation for Connected TV products and services that service providers such as Sky can build on for trademark requirements. YouView will support a competitive market for Connected TV to bring the widest possible choice of devices, services and applications to consumers. Our continued participation in the DTG s work to establish a standard for Connected TV devices, alongside other DTG members, helps us achieve this aim. YouView compliant devices will undergo a comprehensive test and compliance regime that will not only comply with the current D-Book technical standards, but also reference the relevant specifi cations in D-Book 7, currently being agreed as part of the DTG s Connected TV work. Richard Halton, Chief Executive Offi cer, YouView 08 Digital TV Group Setting the standards for the digital future

This consultation process will play a key role in ensuring the Group is able to work with its members to produce a roadmap for the ongoing interoperability, stability and technical development of UK digital terrestrial television. Connected TV Connected TV is the term used by the digital television industry to refer to the delivery of programmes, films, applications and interactive services to the television via broadband. The DTG Council, executive and its members are currently developing the technical specification for UK Connected TV which will form part of the 7th edition of the D-Book. D-Book 7 will provide an industry agreed baseline implementation for Connected TV products and services that service providers such as YouView, Fetch TV, Lovefilm, Sky, Virgin Media and others can build on for trademark requirements to support their services. The DTG has set up 7 Connected TV working groups drawing upon different areas of the specification: architecture, device, delivery, presentation, metadata, security and measurement. D-Book 7 will be circulated to members in December 2010, followed by a Connected TV test and conformance regime to ensure market compliance in May 2011. 3DTV Successes such as Avatar, Sky s 3D channel and 3D broadcasts of major sporting events have stimulated consumer demand for 3DTV content. A technical standard has been completed for 3D Blu-ray and HDMI 1.4a is ready for carrying 3D. Following feedback from the DTG s consultation on developments in 3DTV, the DTG is to work with its members to investigate options for profiling the UK standard for 3D products and services. 09

Getting to market Image: Freeview The DTG and DTG Testing support manufacturers from product development, through launch and into the home. The D-Book provides the basis for the development of Freeview and Freeview HD set-top boxes, recorders and IDTVs in the UK. DTG Testing produces test suites, recognised by the Department of Business, Innovation and Skills (BIS), as demonstrating the required standard for the Digital Switchover Certification Mark (the Digital Tick ). Manufacturers use DTG Testing s test suites to carry out pre-compliance testing of products to ensure they meet benchmark interoperability standards for the Freeview and Freesat services. Product testing at DTG Testing is used by manufacturers to demonstrate conformance to the Digital Tick certification mark requirements and the Freeview, Freeview HD and Freesat trademark requirements. After a product has been launched, the DTG Engineering Channel provides manufacturers with a mechanism to upgrade a receiver s software in the home. The great achievement of the last decade was to deliver a completely reliable, robust offer to the public, and I think it s because of that and in particular because of the work of the DTG, that the public have so much confi dence in digital TV. Mark Thompson, Director General, BBC DTG continues to play an important strategic role in the success of the Freesat platform by testing all new receivers to ensure they meet the exacting quality levels Freesat customers demand.

Working in partnership As a leading manufacturer of digital TV products in the UK, Panasonic has long recognised that it is in the best interest of the viewer that the industry works in partnership to achieve robust open standards. The independent, collaborative environment of the Digital TV Group makes this possible. DTG membership has provided Panasonic with the opportunity to actively participate in the development of the UK DTT standard (the D-Book). This, in addition to DTG Testing s test and conformance regimes allow us to build reliable, industry certified products, drastically reducing the risk of market failure and helping us to ensure a consistent high quality consumer experience. Panasonic is committed to ensuring our products use the DTG s conformance tests in order to receive the Digital Tick, Freeview, Freeview HD and Freesat logos. Our relationship with the DTG doesn t end at product launch; Panasonic is also a member of the DTG Engineering Channel which enables us to transmit over-air software updates to devices in the home, ensuring that our customers continue to receive the most up-todate service. We submit a representative sample of all our tested products to the DTG s receiver collection this allows the DTG to run regular tests to check the response of deployed products in scenarios such as a regional switchover. To ensure we continue to offer customers the best possible technology, Panasonic is currently participating in the development of the technical specification for UK Connected TV through the DTG s working groups. Nigel Prankard DVB Product Manager, Panasonic Supporting innovation As an industry leader and innovator in the connected TV arena, IP Vision fully supports the DTG s Connected TV programme. The D-Book s focus on open standards not only promotes a fair and competitive market but also delivers the interoperability baseline critical to a fast growing and dynamic industry. The convergence of DTT and IPTV presents many challenges, especially in the development of services that are easily accessed and understood by the consumer. The DTG s focus on Connected TV will without doubt support this process. Eddie Abrams CEO, IP VISION 11

Test development DTG test suites are the only UK industry-approved solution for demonstrating conformance to the requirements of the UK s Digital Tick certification mark and the Freeview, Freeview HD and Freesat trademarks. The DTG s test development is based on technical excellence. Starting from specifications (such as the D-Book) the DTG s core team of test suite development specialists identify functional features and define a set of test vectors to test those features in real-world scenarios. The test streams are created using a number of existing tools optimised for test production. The flexibility of these tools allows staff to re-purpose streams for various systems without affecting the functionality being tested, reducing the cost of verification and validation of new platforms. Along with test streams, the test development team provides a number of support documents. For receiver developers the test house provides descriptions of the test vectors so that faults can be quickly traced and fixed. Operator instructions and pro-forma report sheets are also provided for test lab use. Product testing The Digital TV receiver industry founded DTG Testing over a decade ago to carry out interoperability testing on digital terrestrial receivers. Today, the test centre is a Department of Business, Innovation and Skills (BIS) recognised testing facility for the Digital Switchover Certification Mark (the Digital Tick ) and is the UK s test house for the Freeview, Freeview HD and Freesat trademarks. DTG Testing is the only ISO/IEC 17025 accredited digital television product test facility in the UK 1. ISO/IEC 17025 is the UK standard for calibration and testing laboratories. Connected TV testing Following the completion of D-Book 7, the technical specification for UK Connected TV products and services, DTG Testing is to launch the UK test and conformance regime for Connected TV products in May 2011. The test centre will also provide a test and conformance service for HbbTV devices and is working with the YouView partners on the development of a test and conformance regime for YouView products. These new services have been designed to ensure that manufacturers launching products in the UK have a single test and conformance facility for Freeview, Freeview HD, Freesat, Digital Tick, Connected TV and HbbTV set-top boxes, IDTVs and digital recorders. Engineering Channel DTG Testing manages the UK Engineering Channel which is used for over-air upgrades to receiver software and interactive application testing for the Freeview, Freeview HD and Freesat services. All major receiver manufacturers supplying the UK market have service agreements with DTG Testing for access to the Engineering Channel. DTG Testing manages the scheduling of over-air downloads to ensure that all manufacturers have access to the capacity available with little delay and adequate transmission durations. Receiver collection DTG Testing s laboratory houses the UK s largest collection of representative samples of DTT and D-Sat receivers. The collection of over 200 receivers is used to support digital switchover, and the introduction of Freeview HD by gathering data about the capability of receivers deployed in the UK and is used by developers of interactive application for pre-transmission testing. The Department of Business, Innovation and Skills (BIS) require that any manufacturer using the Digital Tick logo must provide a representative sample of the receiver to a recognised test centre such as DTG Testing. Consulting projects The Digital TV Group s unique position makes it ideally placed to provide expert consultancy for organisations who wish to enter the UK market and for those developing services internationally. The DTG s team of core industry experts has been instrumental in the launch of services such as Freeview, Freeview HD and Freesat and the introduction of widescreen TV, DVB-T2/MPEG-4 and more recently, Connected TV. The Group offers the independent, impartial and expert consultancy to both members and non members that empowers organisations to make informed management decisions, allowing you to take full advantage of business development opportunities both in the UK and internationally. 1 Freeview (SD) only 13

The DTG Test Development team produces the test suites that are used by DTG Testing to test products and by manufacturers for pre-compliance testing. Every engineer in the team has a different area of expertise such as SI, Linear Services and my role is to develop MHEG and DTR test suites. The DTG s Freeview MHEG test suite is the result of thousands of man hours of development by DTG staff and members and is continually enhanced and refined based on feedback from customers. Freeview MHEG provides the core source code that we build on to incorporate D-Book developments and to provide test suites for new services such as Freeview HD. To replicate the DTG s MHEG test suite would take a huge amount of resource and effort and as a result we are often asked to adapt the suite for other territories such as Australia, New Zealand and Hong Kong. My working day is divided between code creation for new or enhanced test suites and the maintenance of existing suites. It s also important to make time to deal with enquiries and feedback from customers and from colleagues in the Product Testing team, such feedback is absolutely crucial in ensuring that every test suite we produce is as easy to use and as reliable as possible. Mark Skinner, Senior Project Engineer, DTG Testing While a large part of my working day is devoted to actively testing products, I am also responsible for ensuring the smooth running of the product testing process, supporting and mentoring the conformance engineers and dealing with technical enquiries from clients. Away from product testing, I also coordinate many of DTG Testing s special projects. As part of the DTG s support for digital switchover we are currently using our receiver collection to simulate the effects that various switchover scenarios will have on receivers in the home. The DTG receiver collection represents over 95% of deployed receivers this means that Digital UK can confidently predict the effects that different changes to broadcast signals will have on viewers receivers well in advance of a regional switchover. Another important service offered by DTG Testing is the Engineering Channel which allows manufacturers to provide over-air upgrades to the software in deployed Freeview and Freesat receivers. I work with the team here to ensure all upgrades are thoroughly tested and are transmitted to schedule. Ranjeet Kaur, Head of Product Testing, DTG Testing 15
