Executive summary
The present document complements ETSI EN 301 549 [i.1] which covers a wide range of requirements for a variety of
ICT solutions. TV manufacturers identified the need to develop a technical report with a focus on TV products [3.1].
TV has a unique set of features which typically operate as a system in combination with content providers offerings. As
a result TV manufacturers developed the present document to give clarification for manufacturers towards producing
TV that comply with the European Accessibility Act (EAA) [i.3] and the associated Harmonised Standard ETSI
EN 301 549 [i.1].
