IEC 62944:2016(E) specifies a set of principles and considerations for digital television products in support of older people and persons with disabilities in addition to mainstream users. The effect of following the principles and considerations as set out in this document is to ensure that the widest range of users can access, understand and use digital television products. These principles and considerations cover four main user profiles such as individuals with hearing impairments, individuals with sight impairments, individuals with mobility impairments and individuals with cognitive impairments.

Systèmes et équipements audio, vidéo et multimédia - Accessibilité à la télévision numérique - Spécifications fonctionnelles
L'IEC 62944:2016 spécifie un ensemble de principes et préceptes pour les produits de télévision numérique destinés aux personnes âgées et aux personnes handicapées, en plus des utilisateurs conventionnels. Le respect des principes et préceptes spécifiés dans le présent document permet de s'assurer que la plupart des utilisateurs peuvent accéder aux produits de télévision numérique, mais également les comprendre et les utiliser. Ces principes et préceptes concernent quatre profils d'utilisateurs principaux, à savoir les personnes malentendantes, les personnes malvoyantes, les personnes à mobilité réduite et les personnes souffrant de déficiences cognitives. Le présent document s'applique aux solutions grand public dont la fonction principale est de recevoir la télévision numérique, comme les téléviseurs numériques intégrés, les boîtiers décodeurs, les enregistreurs numériques et les produits et dispositifs équivalents (voir Annexe D). Toutes ces solutions sont appelées solutions de télévision numérique dans l'ensemble du présent document. La présente norme ne traite pas des solutions pour lesquelles la prise charge de la télévision numérique constitue une fonction secondaire (consoles de jeux ou ordinateurs équipés d'une carte de réception numérique, par exemple). Toutefois, une grande partie de son contenu prévoit également l'intégration de futures solutions et/ou mises en œuvre. Le présent document ne traite pas de la livraison, du déballage, du montage en toute sécurité sur un support ou au mur, ni du premier branchement de l'alimentation électrique et des signaux.
Avdio, video in večpredstavnostni sistemi in oprema - Digitalna dostopnost televizije - Funkcionalne specifikacije (IEC 62944:2016)
Ta dokument določa sklop načel in opomb za izdelke, povezane z digitalno televizijo, ki zagotavljajo pomoč splošnim uporabnikom, pa tudi starejšim in invalidnim osebam. Cilj načel in opomb iz tega dokumenta je zagotoviti, da lahko kar največ uporabnikov dostopa, razume in uporablja izdelke digitalne televizije. Ta načela in opombe zajemajo štiri glavne profile uporabnikov, kot so posamezniki z okvarjenim sluhom, posamezniki z okvarjenim vidom, posamezniki s težavami pri gibanju in posamezniki s slabšimi kognitivnimi sposobnostmi.
Ta dokument se uporablja za potrošniške rešitve, katerih glavna funkcija je sprejemanje digitalnega televizijskega signala, kot so vgrajene digitalne televizije, komunikatorji, snemalniki digitalne televizije ter enakovredni izdelki in naprave (glej dodatek D). Vse te rešitve v tem dokumentu imenujemo rešitve za digitalno televizijo. Standard ne zajema rešitev, ki podpirajo digitalno televizijo kot sekundarno funkcijo (na primer igralnih konzol ali računalnikov s karticami za digitalni sprejem). Velik del vsebine se nanaša tudi na prihodnje rešitve in/ali uvedbe. Ta dokument ne zajema dobave, odstranjevanje embalaže, varne namestitve na stojalu ali stenske montaže oziroma prvega priklopa napajanja in signalov.
