Abstract: Disclosed is a method for managing multimedia content, involving: obtaining a first set of content description metadata describing a first multimedia content broadcast in dynamic mode; and upon reading, in the first set of metadata, data redirecting to a section of a second set of content description metadata, reading, in the section of the second set of metadata, data relating to a time synchronization for accessing a second multimedia content broadcast in dynamic mode.

Abstract: A method for managing multimedia contents is proposed, which method comprises: obtaining a first set of multimedia-content description metadata describing a first multimedia content delivered in dynamic mode; on reading, from the first set of metadata, a splice indicator indicating a splice to a second set of multimedia-content description metadata, reading, from the first set of metadata, an address storage indicator; and storing, in a memory, an address of the first set of metadata.

Abstract: A method for processing a multimedia content previously digitally encoded into an audio-video stream and transmitted from a distribution platform for the purposes of on-demand transmission to a plurality of receiving terminals includes the following steps: applying a demultiplexing function to the audio-video stream, said function being arranged to generate at least one group of data streams; applying a transformation to each data stream; segmenting each data stream; storing the at least one group of segmented data streams in a memory; carrying out, only in response to a request issued by a receiving terminal among the plurality of receiving terminals, the following steps: selecting, on the basis of the request, at least one data stream of at least one group of stored data streams; and transmitting the at least one selected data stream to the receiving terminal that issued the request.
