Abstract: A method and an apparatus for matching corresponding frames in two multimedia streams are suggested. The first multimedia stream is an original multimedia stream for which meta-data are available. The second multimedia stream is broadcasted or multi-casted multimedia stream and has undergone processing steps such that the meta-data of the original video stream are no more available or no longer reliable. The matching of corresponding frames in the two multimedia streams is based on the comparison of audio fingerprints and the detection of shot boundaries. Matching corresponding frames with frame accuracy enables inserting targeted content like advertisements into a sequence of video frames especially in a broadcast or multicast environment where meta-data and time markers cannot be relied upon.

Abstract: A method for restoring a service reservation booking system in a network after a failure, that comprises a first step of invalidating at least a portion of the bookings which cannot be seen anymore by the service booking system due to the failure, a second step of recalculating the bookings which cannot be seen anymore by the service booking system by validating the bookings which are valid in the network topology after the failure and by cancelling the bookings which are invalid in the network topology after the failure. Advantageously, the method of the present invention further includes a third step during which the nodes of the network disappear from the service booking system. The present invention also includes to a service booking system in a network.

Abstract: A device and a method for online storage, device and method for searching for similar content, a device and a method of transmission and a device and a method. Encrypted data is saved at a provider of online services. With the encrypted data, encrypted hashing data is saved with a public key and the content to save is encrypted with the encrypted hash. This advantageously enables data duplication at the online service provider to be prevented while preserving the private life of the users of the service. In order to search for content similar to reference multimedia data, fingerprints are also saved at the service provider. In order to limit the number of false positives returned, the fingerprint can further contain a search fingerprint, an encrypted selection fingerprint.

Abstract: A method and an apparatus for inserting content into a transmitted video stream without modifying the original content are suggested. The transmission of videos stream is performed by broadcasting or multicasting. The insertion of content works in real-time and does not require computing overhead compared to conventional solutions. Synchronization of the original videos stream and the transmitted video stream is required for properly inserting the content. This synchronization is performed in two steps. A first step involves a coarse synchronization and in a second step a fine synchronization is applied to the result of the coarse synchronization. The coarse synchronization is based on audio-fingerprints while the fine synchronization is based on video fingerprints. The insertion of content is unsusceptible to processing or transformation steps of the original video along the broadcast or multicast chain.
