Anotation

IEC 60461:2012 specifies a digital time and control code for use in television, film, and accompanying audio systems operating at nominal rate of 60, 59, 94, 50, 30, 29, 97, 25, 24 and 23,98 frames per second. This International Standard specifies a time address, binary groups, and flag bit structure. In addition, the standard specifies a binary group flag assignment, a linear time code transport, and a vertical interval time code transport. It cancels and replaces the third edition published in 2001, of which it constitutes a technical revision. It includes the following significant change with regard to the previous edition: The time code for progressive television systems with a frame rate greater than 30 frames per second is added. This bilingual version (2012-01) corresponds to the monolingual English version, published in 2010-03. La IEC 60461 :2010 specifie un code temporel et de commande numerique destine aux systemes de television, films et systemes audio annexes, fonctionnant a des frequences image nominales de 60, 59,94, 50, 30, 29,97, 25, 24 et 23,98 images par seconde. La presente Norme internationale specifie une structure dadresse temporelle, de groupes binaires et de bits drapeaux. Cette norme specifie en outre une affectation des drapeaux des groupes binaires, un transport lineaire du code temporel et un transport du code temporel dans lintervalle vertical. Cette quatrieme edition annule et remplace la troisieme edition parue en 2001, dont elle constitue une revision technique. Par rapport a ledition precedente elle comporte la modification significative suivante: est ajoute le code temporel pour des systemes de television a balayage progressif de frequence image superieure a 30 images par seconde. La presente version bilingue (2012-02) correspond a la version anglaise monolingue publiee en 2010-03.
