Digital video interface - Gigabit video interface for multimedia systems
IEC 62889:2024 describes two serial digital interfaces, Gigabit Video InterFace (GVIF) and Gigabit Video InterFace2 (GVIF2), for the interconnection of digital video equipment. GVIF and GVIF2 are primarily intended to carry high-speed digital video data for general usage and are well suited for multimedia entertainment systems in a vehicle. This document specifies the physical layer of the interface, including transmission line characteristics and electrical characteristics of transmitters and receivers. Mechanical and physical specifications of connectors are not included. IEC 62889:2024 cancels and replaces the first edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Addition of a new technology interface, GVIF2.
Interface vidéo numérique - Interface vidéo gigabit pour les systèmes multimédias
L'IEC 62889:2024 décrit deux interfaces numériques série: l'interface vidéo gigabit (GVIF) et l'interface vidéo gigabit 2 (GVIF2), qui permettent l'interconnexion de matériels vidéo numériques. La GVIF et la GVIF2 sont principalement destinées à transporter des données vidéo numériques à grande vitesse pour un usage général et sont bien adaptées aux systèmes de divertissement multimédia pour véhicule. Le présent document spécifie la couche physique de l'interface, notamment les caractéristiques de la ligne de transmission et les caractéristiques électriques des émetteurs et des récepteurs. Les spécifications mécaniques et physiques des connecteurs ne sont pas incluses. L'IEC 62889:2024 annule et remplace la première édition parue en 2015. La présente édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Ajout d'une interface de nouvelle technologie, la GVIF2.
