Patent

CA 2247632

The invention provides a method for facilitating the management and running of a digital video broadcast (DVB) system. In a typical DVB system there are often a number of functions which must be co-ordinated and synchronized. The invention provides a monitoring point for managing the total multiplex, and controlling the mix of services being transmitted. The system fulfils most of the software integration requirements in a broadcast centre. A central database, held in the operational areas, is provided and is the reference point to which other systems refer. A large protocol converter is provided which links the scheduling system to the playout and conditional access (CA) systems.

L'invention concerne un procédé pour faciliter la gestion et le fonctionnement d'un système de radiodiffusion vidéonumérique (RDV). Dans un système RDV typique, il existe souvent un certain nombre de fonctions qu'il faut coordonner et synchroniser. L'invention porte sur un point de surveillance du multiplexage général et de surveillance du mélange des services transmis. Le système répond à la plupart des contraintes en matière d'intégration de logiciels dans un centre de radiodiffusion. Il est prévu une base de données centrale, conservée dans les zones d'exploitation et constituant le point de référence auquel d'autres systèmes s'adressent. Il est également prévu un convertisseur de protocoles de grande dimension qui lie le système d'ordonnancement aux systèmes d'émission d'accès conditionnel.
