General methods of measurement for digital television receivers
IEC 62028:2002 describes standard conditions and methods of measurement on digital television receivers which receive digital television broadcast transmissions. It deals with the determination of performance and allows the comparison of equipment by listing the characteristics which are useful for specifications and by laying down uniform measuring methods of these characteristics. Performance requirements are not specified, since they are specified by other international, regional or domestic standards for the systems. This bilingual version corresponds to the monolingual English version, published in 2002-02.
Méthodes de mesure générales pour récepteurs de télévision numériques
La CEI 62028:2002 traite des conditions et méthodes standardisées de mesure des récepteurs de télévision numérique qui reçoivent de la télévision numérique radiodiffusée. Elle traite de la détermination des performances; elle permet la comparaison des matériels en énumérant les caractéristiques utiles pour les spécifier et en définissant des méthodes de mesure uniformes de ces caractéristiques. Les exigences en performances ne sont pas spécifiées, puisqu'elles sont détaillées dans d'autres normes internationales, régionales ou nationales pour les systèmes. La présente version bilingue correspond à la version anglaise monolingue publiée en 2002-02.
