Principes techniques et classification par niveaux[modifier | modifier le code] Le standard HDMI permet d'exploiter différents formats vidéo numériques, parmi lesquels la définition standard (SD), la définition améliorée (ED) et la haute définition (HD) ainsi que le son multi-canal, en véhiculant les données complètes grâce à un seul câble.
Certaines données complémentaires sont également véhiculées par ce standard (commutation, synchronisation, informations stéréoscopiques…). Plusieurs niveaux distinguent le standard HDMI; ils sont symbolisés par un nombre et éventuellement une lettre, associé à l'acronyme ; par exemple : HDMI 1.0, HDMI 1.3, HDMI 1.4a, etc. HDMI est transparent aux différentes normes de télédiffusion ou transmissions numériques telles que la télévision numérique terrestre, l'IPTV, la télévision numérique par satellite ou par câble.
