  • Patent number: 10075680
    Abstract: An embodiment of a video-surveillance method comprising: activating a video camera for acquiring, for a surveillance system comprising the aforesaid video camera, a digital video sequence of images of a scene to be surveyed, detecting given events and transmitting to a remote center images of the aforesaid digital video sequence of images acquired according to the result of the aforesaid operation of event detection. An embodiment includes: executing an operation of extraction of key frames on the aforesaid digital video sequence of images for composing a visual storyboard, detecting given events on the basis of data supplied by one or more event sensors for generating an event signal, controlling operating states assumed by the aforesaid key-frame-extraction operation as a function of the values assumed by the aforesaid event signal, and transmitting the aforesaid visual storyboard to the aforesaid remote center.

  • Patent number: 9917886
    Abstract: In an embodiment, information contents, such as, e.g., media contents arranged in pieces including blocks of bits, is distributed over a network including plural terminals at least one of which acts as a source of the pieces of information distributed. Various terminals in the network are configured to act as peer terminals with at least one first peer terminal sending the information to one or more second peer terminals. A set of blocks of a corresponding piece of information is received at the first peer terminal and the corresponding piece of information is reconstructed from the set of blocks received. The pieces of information distributed over the network are fountain encoded by XOR-ing the blocks in a piece, so that a received piece is reconstructable from a combination of a corresponding set of linearly independent XOR-ed blocks.

  • Publication number: 20160287179
    Abstract: An embodiment of a multimedia tagging system, includes a multimedia-content generator for producing multimedia content tagged with metadata, and a remote health-monitoring device for measuring and processing a set of biological and physiological signals of a user. The system is configured for tagging the multimedia content with tags extracted from a set of personal metadata obtained from the biological and physiological signals provided by the remote health-monitoring device and containing information relative to the emotional and health status of said user.

  • Patent number: 9258145
    Abstract: The interfacing of coded media data packets in the transfer from and to a peer-to-peer network envisages that the data packets are included in groups of packets that may have lengths different from one another. Each group of data packets is encapsulated in a group of chunks of given length. The media data is made available in the network as a multiplicity of different descriptions of a multiple-description coding of one and the same media content. The terminals of the peer-to-peer network are configured for accessing selectively the multiplicity of different descriptions of said media contents, combining them with one another, or else accessing one of the different descriptions in substitution for another preserving access to the media contents. The data may be made available as base layer and at least one enhancement layer of one and the same media content.

  • Patent number: 8843744
    Abstract: A method of distributing media content over networks where content is shared includes coupling downloading metadata, which is accessed to start downloading media contents from the network, with semantic metadata representative of the semantic information associated with at least one of the content, and with source metadata indicative of the source of the media content. At least one of the semantic and the source metadata may be made accessible without downloading, even partially, the media content. A digital signature may also be applied to the metadata to enable the verification that, at reception, the metadata is intact and has not been subjected to malicious tampering.

  • Patent number: 8694599
    Abstract: Information codes are arranged in pieces comprised of chunks of bytes over a network, such as a Peer-to-Peer overlay network, including a set of peer terminals. A first peer identifies missing chunks in the received pieces and requests such missing chunks from other peers. The chunks are subjected to a fountain code encoding wherein the chunks in a piece are X-ORed. The first peer is therefore capable of reconstructing a received piece encoded with fountain codes from a combination of linearly independent chunks corresponding to the piece. The chunks are transmitted over the network with a connection-less protocol, without retransmission of lost packets, preferably with a UDP protocol.

  • Publication number: 20130336590
    Abstract: An embodiment includes a method and an apparatus for the generation of a visual story board in real time in an image-capturing device including a photo sensor and a buffer, wherein the method includes the consecutively performed steps: starting the recording of a video, receiving information on an image frame of the video, comparing the information on the received image frame with information on at least one of a plurality of image frames wherein the information on the plurality of image frames has previously been stored in the buffer, storing the information on the received image frame in the buffer depending on the result of the comparison, and finishing the recording of the video.
