Abstract
(EN)
A method of processing EPG metadata in a network device includes performing a services discovery procedure utilizing multiple service discovery metadata components supplied by a service provider, and requesting specific SGDDs (service guide delivery descriptors) or specific fragments.
(FR)
L'invention porte sur un procédé de traitement de métadonnées de guide électronique de programmes (EPG) dans un dispositif de réseau qui consiste à réaliser une procédure de découverte de services utilisant de multiples composantes de métadonnées de découverte de services fournies par un fournisseur de services, et à demander des SGDD (descripteurs de délivrance de guide de service) spécifiques ou des fragments spécifiques.
