Patent

CA 2584765

A parameter set is created to specify chroma format, luma bit depth, and chroma bit depth for a portion of multimedia data. The parameter set is encoded into a metadata file that is associated with the multimedia data. The parameter set is extracted from the metadata file if a decoder configuration record contains fields corresponding to the parameter set. In another aspect, the decoder configuration record is created with fields corresponding to the parameter set.

Selon l'invention, un ensemble de paramètres est créé pour spécifier un format de chrominance, une profondeur de bits de luminance et une profondeur de bits de chrominance pour une partie de données multimédia. Cet ensemble de paramètres est codé en un fichier de métadonnées associé aux données multimédia. L'ensemble de paramètres est extrait du fichier de métadonnées si un enregistrement de configuration de décodeur contient des champs correspondant à l'ensemble de paramètres. Dans un autre aspect, l'enregistrement de configuration de décodeur est créé avec des champs correspondant à l'ensemble de paramètres.
