<p>The invention concerns an error-protection method for an information called initial information, describing or modifying a multimedia scene, said scene being represented by a set of elementary graphic and/or audio objects constituting the scene, said initial information enabling reproduction or modification of at least one of said objects. The method consists in forming groups of elementary objects, each of said groups comprising at least one of said objects, a group being adapted to contain one or more other groups in a tree-like structure, each group thus formed being independently error-protected, and in generating an additional information identifying each of said groups. The invention also concerns the corresponding error correction method.</p> |
