摘要:
This method for synchronizing two versions (4,6) of a multimedia content, each version (4,6) comprising a plurality of video frames, comprises steps of: a) extracting (20) audio fingerprints from each version (4,6) of the multimedia content; b) analyzing (24,26,28) the extracted audio fingerprints in order to determine at least one temporal matching period between both versions (4,6); c) exploiting (30,32) the determined temporal matching period to perform a mapping (34) between the video frames of both versions (4,6).
摘要:
The present invention relates to a radiating device intended to receive and/or transmit electromagnetic signals comprising at least two antennas (A1, A2) connected by slot and having a common slot (FC). Connection means (L, P) enable at least one antenna (A) to be connected to processing means of electromagnetic signals. The connection means (L, P) include two connection lines (L1, L2) connected to the processing means. The two lines (L1, L2) are terminated by an open circuit and are coupled electromagnetically to the common slot (FC) of the two antennas (A1, A2) so as to enable a phase difference to be introduced between the electromagnetic signals of the two antennas (A1, A2) when the connection is switched from one line to the other by means of a switching device (3) present on the connection lines (L1, L2).

The present invention relates to a multiband planar antenna consisting of at least one resonator (20) formed of an element having a closed shape made on a substrate and dimensioned so as to operate in its fundamental mode at the resonant frequency of the lowest band. The resonator is fed by a feed line (21) in such a way as to operate in all the higher modes. The resonator comprises means (22a, 22b, 23a, 23b, 23c, 23d) for modifying the resonant frequencies of the various modes in such a way as to cover the bands concerned. The invention applies in particular in wireless networks.
摘要:
A method of encoding a packet (214) comprising data representative of a haptic effect, the haptic affect being associated with an immersive content. The method comprises adding a first information in the packet (214), the first information being representative of a dependency of said haptic effect with regard to a position of a body model in relation to the immersive content; adding a second information in the packet, the second information being representative of at least a first part of the body model targeted by the haptic effect. A method for decoding the packet (214) and corresponding devices are also recited.
摘要:
The antenna has concentric outer and inner annular slots (60, 62), each comprising two rectangular protrusions (61, 63) on its outer and inner rim, respectively. The slots are supplied through two accesses by two common supply lines (64, 65) that cut across the slots in the directions of the respective protrusions. The slots allow an operating frequency of two sub-bands to be modified.

A method is suggested enabling a person that watches a TV broadcasted live event to select and associate in a simple manner to the displayed video, an audio stream dealing with the same event but delivered by another source than the TV channel. The method relies on techniques allowing to know and to decode some available audio streams that deal with the same live event as the one currently displayed on TV and to synchronize these audio streams with the TV channel.

The invention relates to a dual-band planar antenna formed by at least one slot of closed shape fabricated on a printed substrate having a perimeter equal to kλ f , and two supply lines supplying power to the slot via two accesses separated by (2m+1)λ f /4, where λ f is the guided wavelength in the slot and k and m integers greater than 0, the slot comprising means modifying the operating frequency, one of the supply lines being situated on the said means. The invention is especially applicable to antennas used in domestic wireless networks (IEEE802-11a or Hyperlan 2 standards).
摘要:
The present invention concerns a method for editing an audiovisual segment from a plurality of pieces of audiovisual content related to an event. The method comprises the steps of: a) selecting (S1), among said plurality of pieces of audiovisual content, an audiovisual segment, called reference segment, associated to at least a part of said event, b) determining (S2), among said plurality of pieces of audiovisual content, audiovisual segments temporally synchronized with said reference segment, c) determining (S3), among the reference segment and the synchronized audiovisual segments, a first audiovisual segment based on at least one video feature, d) determining (S4), among the reference segment and the synchronized audiovisual segments, a second audiovisual segment based on at least one first audio feature, and e) generating (S5) the edited audiovisual segment from the video data of the first audiovisual segment and the audio data of the second audiovisual segment.
