(EN) METHOD AND APPARATUS FOR MULTIPLEXING SEPARATELY-AUTHORED METADATA FOR INSERTION INTO A VIDEO DATA STREAM

Abstract
(EN)
An authoring system for interactive video has two or more authoring stations (11) for providing authored metadata to be related to a main video data stream and a multiplexor for relating authored metadata from the authoring sources to the main video data stream. The authoring stations (11) annotate created metadata with presentation time stamps (PTS) from the main video stream, and the multiplexor relates the metadata to the main video stream by the PTS signatures. In analog streams PTS may be created and integrated. In some embodiments there may be multiple and cascaded systems, and some sources may be stored sources. Various methods are disclosed for monitoring and compensating time differences among sources to ensure time coordination in end product. In different embodiments transport of metadata to an end user station is provided by Internet streaming, VBI insertion or by Internet downloading. User equipment is enhanced with hardware and software to coordinate and present authored material with the main data stream.

La présente invention concerne un système de médiatisation destiné à une vidéo interactive comprenant deux ou plusieurs stations de médiatisation (11) destinées à délivrer des métadonnées médiatisées à mettre en rapport avec un flux principal de données vidéo ainsi qu'un multiplexeur destiné à mettre en rapport des données médiatisées provenant des sources de médiatisation avec le flux principal de données vidéo. Les stations de médiatisation (11) annotent des métadonnées créées à l'aide de timbres de durée de présentation (PTS) du flux principal vidéo, et le multiplexeur met en rapport les métadonnées avec le flux principal vidéo au moyen des signatures PTS. Dans des flux analogiques, il est possible de créer et d'intégrer des PTS. Dans certaines réalisations, il est possible d'avoir des systèmes multiples et en cascade, et certaines sources peuvent être des sources stockées. L'invention concerne différents procédés destinés au suivi et à la compensation des différences de durée entre sources de manière à assurer une synchronisation dans un produit final. Dans différentes réalisations, le transport de métadonnées vers une station utilisateur final est effectué par accès Internet à la demande, insertion d'intervalle d'effacement vidéo (VBI) ou par téléchargement sur l'Internet. L'équipement utilisateur est amélioré à l'aide de matériel et de logiciel destinés à coordonner et à présenter du matériau médiatisé avec le flux principal de données vidéo.
