Abstract: Means for managing resale rights for digital objects. The invention relates to a method for managing usage rights, granted to users by a supplier, for a first version of a digital object, comprising the following steps: (a) providing a user with a second version of the digital object, derived from the first version; (b) receiving a request to use at least one subset, however small, of the first version of the digital object, comprising a usage code; (c) checking the validity of the usage code; (d) in case the usage code is assessed to be valid, transmitting decoding information to the user required to reconstitute, from the second version of the digital object, said subset of the first version; (e) updating at least one usage code validity repository.

Abstract: The present application relates to a method for editing and broadcasting compressed multimedia files composed of binary data blocks originating from digital transformations applied to an audiovisual or multimedia content according to the format of a parent file, said parent file having been separated into a first modified file having the format of the nominal parent file and into a complementary file including information on the modifications brought to the parent file, the method comprising prior to the transmission from a portal to the receiving terminal: a step of preparation including analyzing said first file for extracting time-codes therefrom, a second step including generating an index register table from said first modified file, a third step including generating a modified multimedia file according to the format of the parent file containing information of said first modified file and meta-data, a step of transmission of said modified multimedia file separate from said modified multimedia file, t
