Patent

CA 2567029

The installation, maintenance and administration of digital cinema playback systems is facilitated by devices within the playback systems having operator- actuated controls that are used to specify a unique identifier for each playback system in a digital cinema complex. The identifier for a system is used to establish a set of network addresses for that playback system from which device addresses are assigned automatically. Subsequent communication between devices within a playback system use the assigned device addresses. These communications are used to alter the operation of devices, and for devices to publish the existence of and the need for specified, services.

L'invention porte sur l'installation, la maintenance et l'administration de systèmes de play-back de cinéma numérique, ceci étant facilité par des dispositifs se trouvant à l'intérieur des systèmes de play-back possédant des commandes activées par un opérateur et qui sont utilisées pour déterminer un identificateur unique pour chaque système de play-back d'un complexe de cinéma numérique. L'identificateur d'un système est utilisé pour établir un ensemble d'adresses réseau pour ce système de play-back à partir duquel des adresses de dispositifs sont affectées automatiquement. Les communications ultérieures entre des dispositifs d'un système de play-back utilisent les adresses de dispositifs affectées. Ces communications sont utilisées pour modifier le fonctionnement des dispositifs, et pour des dispositifs afin de montrer l'existence et le besoin de services spécifiques.
