A system and method for performing seek or jump functions in a digitally stored audiovisual file are described. When the audiovisual file is recorded onto a storage medium, headers, which are distinct and separable from the audiovisual file datastream, are set in the audiovisual file in the storage medium. Each header contains a timestamp. When jumping / seeking, an estimated position for the desired timepoint on the storage medium is calculated by multiplying the storage unit per time unit rate by the desired timepoint. Then the system and method jumps to the estimated position, where the timestamp in the nearest header is checked to determine whether the time it indicates is close enough to the desired timepoint. If it is not, a new estimated position is calculated and the method repeats until either an iteration limit is reached or the estimated position is determined to be close enough to the desired timepoint.

A level of similarity is determined for each matrix cell. Then a clustering algorithm is applied to cluster the information comprised in the similarity matrix. Clusters are identified, each identified cell cluster identifying an object in the audiovisual document.

A communication network performs a method of managing recordings. The communication network comprises a plurality of audiovisual terminals furnished with recording means. The method comprises determining the most adapted terminal among the plurality for recording a specific document. Values of fit are calculated from attributes associated with the document and attributes associated with each terminal. The terminal whose value of fit is the greatest is selected and used for recording this document. The morality of the document and the maximum level of morality accessible from the terminal being compared in order to barre the recording of the document in a terminal if the morality level of this document is higher than the morality level of this terminal.

The invention relates to a method and a device for synchronising metadata associated by a first signature to a first version of an audiovisual document, with a second version of this audiovisual document. The method is characterised in that it synchronises the metadata with the second version of the audiovisual document from a second signature detected in the portion of the second version of the audiovisual document, said portion of the second version of the audiovisual document being obtained by detecting the first signature in the second version of the audiovisual document. In this way, the precision of the synchronisation between the two items of video content carried out by the first signature is improved by the second signature, and new, more accurate metadata is created.

A tamperproof date / time stamp method that adds a real-time tamperproof date / time stamp to a digital audiovisual file includes generating at least one real-time date / time stamp and applying the date / time stamp to the digital audiovisual file. The real-time date / time stamp can be created through the location-based service in tablet computers. It can also be created through an internal clock running in the background of the application that incorporates the correct date / time from an Internet handshake with a remote server. A system for audio or video recording using a tablet computer includes an audio or video recording software module and a time-stamp software module that generates at least one real-time date / time stamp.

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, the elements of said complementary file making it possible to recreate a partial synthesis of the original audiovisual file.
