Abstract: A method and a device for clustering sequences of multimedia contents with regard to a certain event are recommended wherein mel-frequency cepstrum coefficients of the sequences audio tracks of the multimedia contents are used for clustering and synchronizing multimedia contents with regard to a certain event by computing salient mel-frequency cepstrum coefficients from mel-frequency cepstrum coefficient features and clustering sequences having an overlapping audio segment by comparing the salient mel-frequency cepstrum coefficients. Method and device provide an improvement in comparison to fingerprint detection.

Abstract: This method for synchronizing two versions of a multimedia content, each version comprising a plurality of video frames, comprises steps of: a) extracting audio fingerprints from each version of the multimedia content; b) determining at least two temporal matching periods between both versions using the extracted audio fingerprints; c) mapping the video frames of both versions using the determined temporal matching periods.

Abstract: A method and a TV receiver for updating child protection information in an IPTV system are suggested. The suggested method switches through all receivable TV channels, searches for child protection information and stores such information together with the associated TV channel number in a memory. If the user switches to a new TV channel then as a first step it is checked if for the newly selected TV channel child protection information is stored and if it is within a predefined allowed range. In this way adolescent users are effectively protected against offensive content.

Abstract: A method and a TV receiver for updating child protection information on the TV receiver are suggested. The suggested method scans receivable TV channels, searches for child protection information and stores such information together with the associated TV channel number in a memory. If the user switches to a new TV channel then as a first step it is checked if for the newly selected TV channel and child protection information is stored and if it is within a predefined allowed range. In this way adolescent users are effectively protected against offensive content.

Abstract: The present invention relates to an antenna system designed to be used in a wireless link, having polarization directions, respectively for reception and emission, identical to the polarization directions, respectively for emission and reception, presented by a similar system placed in a geometric configuration of use that is different from that of the said first system. The invention enables identical devices to be implemented in separate items of equipment and in distinct positions while enabling the antenna pair to function correctly.

Abstract: The invention relates to a method of transmitting time information relating to the clock of the source of a sending part consisting in using a fixed latency indicator signal to authorize the source to insert time information used to slave the clock of the decoder of the associated receiving part to its clock.

Abstract: The gain control method for the RF and IF amplification stages of a bursty data frame reception system enables, following a step for evaluating the received signal strength, the gain adjustment step of the RF amplification stage to be temporarily deferred until a frame structure symbol is received, during which the gain adjustment step of the IF amplification stage takes place simultaneously with that of the RF gain, while retaining an overall gain linearly dependent on the input signal strength.
