Abstract
(EN)
A receiving device receives from a base unit across a network an instruction stream that includes drawing commands for producing graphic frames of a user interface. The receiving device is connected to a display. The receiving device parses the instruction stream to determine the drawing commands and their arguments. The receiving device executes the drawing commands in a graphics engine of the receiving device to generate the graphic frames of the user interface. Executing includes performing rendering functions and interpolating coordinates for animation. The receiving device outputs the graphic frames of the user interface for display.

Selon l'invention, un dispositif de réception reçoit d'une unité de base, sur un réseau, un flux d'instructions contenant des commandes de dessin destinées à produire des trames graphiques d'une interface utilisateur. Le dispositif de réception est connecté à un affichage. Le dispositif de réception analyse le flux d'instructions pour déterminer les commandes de dessin et leurs arguments. Le dispositif de réception exécute les commandes de dessin dans un moteur graphique du dispositif de réception pour générer les trames graphiques de l'interface utilisateur. L'exécution consiste à exécuter des fonctions de rendu et à interpoler des coordonnées pour une animation. Le dispositif de réception émet en sortie les trames graphiques de l'interface utilisateur pour l'affichage.
