Abstract: In a context of transient disturbance occurring ata networking equipment receiving and forwarding data packets on a plurality of links according to a scheduling policy, a salient idea is to detect retransmitted packets among the received packets, the retransmitted packets being received by the networking equipment, corresponding to retransmissions of packets previously received and forwarded by the networking equipment on one of the links. The retransmissions of the packet, previously forwarded on one of the links, are representative of a disturbance of the link and the scheduling policy is advantageously adjusted to balance at least a part of the data traffic from that link to the other links.

Abstract: A system and method are provided for detecting a behavior patterns of a user. In one embodiment, the method comprises receiving information about activities of a user and calculating duration of each activity. Each activity that exceeds a threshold duration is categorized and labelled accordingly. Activities with similar labels are grouped and labelled activities are analyzing. Alerts are then generated for certain behavioral patterns such as those exhibiting anomalies.

Abstract: A method of decoding an audio/video content transmitted over a broadband network. The method being based on the quick decoding of the first frames of a group of pictures without rendering them if the group of pictures arrives too late to be rendered synchronously with another audio/video content received through a broadcast network. The method allowing the synchronized rendering of contents respectively received over broadcast and broadband networks as soon as possible for the viewer.

Abstract: The invention relates to a storage device management method allowing to manage the storage space, on a storage device, by proposing to an end user to store a new content he was going to consume if its storage determined size is lower than an already stored content size.

Abstract: The invention relates to a method for the synchronization of a set of 3D devices suitable for the processing of data representative of at least one stereoscopic image comprising a first image and a second image.

Abstract: Method and system of access of a mobile terminal to information in an area The present disclosure relates to the field of information retrieval and provides a system and method allowing a mobile terminal (10) to access information in an area. It relies on a dynamic and reconfigurable association between a mobile terminal and a collection of relevant information stored in the database of the area. To this end, the mobile terminal obtains an authorization (13) to access the area, which also enables the mobile terminal to access information relating to objects located in the vicinity of the mobile terminal at the time it enters the area. Such information is stored in a database relative to the area.

Abstract: A signaling method of video content and services broadcast by to a multitude of reception devices, the contents being encoded into data packets transmitted in a transport stream associated with a signaling stream is disclosed that comprises an insertion step of a unique identifier associated with each of the video contents or services in the signaling stream; an insertion step of the unique identifier into packets of the transport stream transmitting the video content or service corresponding to the unique identifier. Advantageously, the unique identifier is derived from a characteristic of the content among the title of the video content or service, the date and theoretical continuous broadcast time of the video content or service. A method for recording and a recording device using the signaling is further disclosed.

Abstract: The present invention relates to a reception device and a method for the processing of multimedia data flows in said device comprising an interface to a first network and an interface to a second network, said method comprising the following steps: receive, from the first network, a first flow comprising multimedia data through a first transport protocol fitted with a first data synchronization system; receive, from the second network, a second flow comprising multimedia data through a second transport protocol fitted with a second data synchronization system, said second synchronization system being based on timing references different from those of the first data synchronization system; characterized in that said first and second flows transport the same synchronization information in the payload field of the first and of the second transport protocol, said synchronization information comprising data indicating the moment from which said multimedia data must be rendered; synchronize said first and second fl
