Inverto become first company to pass DTG Testing and CAI’s European IRS Certification Scheme (EICS)

Inverto have become the first company to pass DTG Testing and CAI’s newly launched European-wide assurance scheme for TV and Satellite distribution equipment known as the European IRS Certification Scheme (EICS). The first scheme of its kind, it will ‘provide reassurance of end-to-end device compatibility, interoperability and robust RF performance within satellite and DTT distribution systems.’

The scheme has been developed through an industry collaboration of satellite and DTT platforms, major equipment manufacturers, and led by industry associations DTG and CAI. It consists of a test specification underpinned by international standards and a consumer-facing logo. Manufacturers of equipment such as receivers, dSCRs, multi switches, fibre gateways, launch amplifiers and LNBs can display the logo on their products after successfully passing the required tests.

Leading supplier of broadcast reception equipment, Inverto, have become the first company to pass the test specification with their 4-port and 8-port dSCR products, demonstrating the high quality of the Inverto solution and compatibility with all major satellite and TV platforms.

Supported by the leading retailers, the logo will ensure a high quality of experience for the end customer. End-users, such as installers, specifiers, housing associations and platform operators can use the logo to recognise equipment that is compatible with all major satellite and TV services; and therefore interoperable with other EICS equipment.

DTG Testing will provide testing against the EICS specification at their UKAS accredited laboratory based in London. CAI will operate the scheme and will include a market surveillance programme to maintain a high standard of EICS-marked equipment.

Alex Buchan, Strategic Technologist at the DTG, said “DTG Testing is delighted to launch this scheme in partnership with the CAI. The new scheme is great news for TV platforms, manufacturers of satellite and TV distribution equipment, and installers who can select products with confidence when they see the EICS mark.”

Peter Sealey, Chairman of CAI, said “CAI are pleased to have worked with DTG Testing to develop this new Product Certification Scheme, which follows on from the success of CAI’s existing Cable and Aerial Certification Schemes.  This new scheme will enable our members, as well as other parts of the industry, to select the best products for their installations.  The EICS mark  will also enable developers, landlords and the specifiers working for them, to ensure they get systems that work as intended, when combined with CAI Codes of Practice and installation by our members.”


LONDON, 2 NOVEMBER 2020: The DTG has released the latest version of the D-Book, the only standard universally deployed in around 6 million TV receivers each year. Created with industry and updated annually, it sets out the technical interoperability requirements for digital terrestrial television in the UK, underpinning Freeview, YouView, Freesat, EE TV, BT TV and TalkTalk TV.

Often described as cross-industry alchemy, as the complexity of the platform increases the importance of interoperability, test, and conformance has never been greater. Each iteration of the D-Book standard and DTG Testing test regime help ensure a level of reliability and quality of experience unmatched by any horizontal TV platform in the world. Underpinned by the seamless interoperability services with televisions, set-top boxes and recorders delivering new levels of performance on the Freeview Platform.

In support of the increased resolution on displays, D-Book 12 ensured all future TVs would support resolutions of HD or above by removing standard definition (SD) receiver profiles. This evolution continues in D-Book 12.5, mainly reflected in the “SI (service information) Rules of Operation” chapter. D-Book 12.5 has an update of the Errata of the HbbTV Specification. In addition, an overhaul of the structure has improved navigation throughout the document with an effort to unify language, and the layout-this edition is called ‘D-Book 12.5’.

The DTG welcomes contributions from members on the evolution towards hybrid distribution systems which will feed into the development of future D-Books. The DTG continues to ensure European and international harmonisation wherever possible while meeting the needs of the rapidly developing and highly successful UK TV market.

Richard Lindsay-Davies, CEO of the DTG said; “A world-first when first published, the DTG D-Book is the culmination of over 25 years of industry collaboration that ensures every UK citizen can enjoy great British television. More importantly than ever, in this extraordinary year, we continue to bring together brilliant engineers from across the sector.  Ensuring that viewers can enjoy the exciting range of content, reliably in the best quality possible, across a wide range of consumer electronics devices.”

Owen Jenkinson, Marketing Director, Freeview said; “The DTG D-Book continues to ensure every television, and Freeview Play recorder and set-top box gives the best possible TV experience to viewers across the UK”

The DTG team give thanks to all who have contributed to D-Book 12.5 which is available to DTG Members as part of their membership and can be downloaded from here // Non-DTG Members can purchase the D-Book for £50,000.
