A system for playing SMIL based multimedia contents, comprising: a plurality of SMIL engines (201) for analyzing and interpereting SMIL documents, as well as communicatin with and controling SMIL sub engines (201), remote media proxies (202) , or local media playing devices; a plurality of remote media proxies (202) for receiving instructions from the upper level SMIL engines, starting or stopping providing media objects to the remote media playing devices, sending back events, and providing basic user interaction capabilities, wherein said a plurality os SMIL engines, a plurality of remote media proxies, and local and remote media playing devices contruct a tree-link structure, of which the root node is a SMIL engine, the branch nodes are SMIL engines and remote media proxies, and the leaf nodes are local and remote media playing devices. The corresponding SMIL engines and methods are also provided. The present invention enables the playing of SMIL based multimedia contents on a set of PvC devices, which can be dynamically configured as a new multimedia terminal on demand.

L'invention concerne un système destiné à la lecture de contenus multimédia au format SMIL, comprenant : une pluralité de moteurs SMIL (201) permettant d'analyser et d'interpréter des documents SMIL et de contrôler des sous-moteurs SMIL (201), des mandataires multimédia éloignés (202) ou encore des dispositifs de lecture multimédia locaux et de communiquer avec ceux-ci ; une pluralité de mandataires multimédia à distance (202) permettant de recevoir des instructions provenant des moteurs SMIL de niveau supérieur, de commencer et d'arrêter à fournir des objets multimédia aux dispositifs de lecture multimédia à distance, de renvoyer des événements, et de fournir des options d'interaction avec l'utilisateur de base, lesdits moteurs SMIL, les mandataires multimédia à distance, ainsi que les dispositifs de lecture multimédia locaux et à distance formant une structure arborescente comprenant un noeud racine constitué du moteur SMIL et de noeuds branches constitués des moteurs SMIL et des mandataires multimédia à distance, les noeuds feuilles étant constitués des dispositifs de lecture multimédia locaux et à distance. L'invention concerne également les moteurs SMIL correspondants et des procédés associés. La présente invention permet de lire des contenus multimédia SMIL sur un ensemble de dispositifs PvC, pouvant être configuré de façon dynamique et sur demande comme un nouveau terminal multimédia.
