The invention concerns a method for detecting manipulation by a user of a device (3), provided with a communication tag (5). The user wears a user terminal (10) provided with a communication tag reader, which detects the communication tag (5) associated with the device (3) as soon as the user is sufficiently close to the device. The communication tag reader (31) is activated after a local area network connection has been established between the user terminal (10) and the device (3), or between the user terminal (10) and a local area network to which the appliance is known to be connected. Through this local network connection (7), the user terminal (10) may also communicate information on the user to the device (3), which then knows who is manipulating (9) its front panel. The device (3) may access a user profile stored in the user terminal (10), in order to deliver a personalized service to the user.

The present invention concerns a transmitting device adapted to send content in bursts in a channel, the channel comprising a plurality of bursts, wherein a burst comprises at least one time slot. The transmitting device comprises first communicating means for receiving content from a first network, second communicating means for sending the content to a second network,the content being successively sent over at least one time slot of the bursts of the channel, time slot means for assigning a channel, and at least one unfilled time slot in the bursts of the channel to at least one second transmitting device located on the second network and signaling means for indicating the channel and the unfilled time slots to the at least one second transmitting device.

The present invention concerns a device and a method for inserting an interactive mark in a streaming content, said method comprising the steps of receiving (S1) a streaming content in a first form, receiving (S2) the same streaming content in a second form, receiving (S3) an interactive mark corresponding to a first frame of said content in a first form and sending (S5) said interactive mark synchronized to a second frame of the content received in the second form, the content in said second frame corresponding to the content in said first frame.
摘要:
The present invention concerns a system and a method for synchronizing interactive content with individual video stream. In particular, it concerns a method for generating an interactive mark, comprising, at a generating device (2.4, 3.4), the steps of receiving (S3) video packets of a video stream, creating an interactive mark intended to enable an interactive service during a period of the video stream, periodically inserting the interactive mark into Internet Protocol packets, noted IP-based packet, said IP-based packets being synchronized with packets that transport the associated video stream, and sending (S7) the IP-based packets.

The invention concerns a method for distributive management of a catalogue of objects in a communication network comprising machines, said method comprising a step for recording the local objects present in a machine in a local register managed at said machine level. The method is characterised in that it consists in: preparing, by a local object, a request for a list of objects, said request being transmitted to the single local register of the machine housing the object; propagating said request by the local register to remote registers; collecting replies to said request by remote registers and the local register reply; transmitting the collected replies to the local object which has made the initial request. The invention also concerns machines capable of being connected to a network wherein said method is implemented. The invention is particularly applicable in the context of home automation communication networks.
摘要:
A method for controlling bandwidth allocation of first and second data packet types in a single rate network by determining, by a device, a throughput rate of the first data packet type in the network and reducing, by the device, the throughput rate of the first data packet type when the throughput rate reaches a predetermined level is described. A method for controlling bandwidth allocation of each of a plurality of data packet categories in a multi-rate network by determining, by a device, a throughput rate of one of a plurality of data packet categories/classes (the j th data packet category) and reducing the throughput rate of the j th data packet category when the throughput rate reaches a predetermined level, wherein a maximum bit rate of a data packet category is based on a distance between members of the data packet category and the device and wherein said j th data packet category transmits TCP packets, is described.

The invention concerns a method for controlling devices in a home network by a control device through a home access server. The method comprises the steps of: providing, in the home access server, a plurality of generic user control protocol pages for each functional component type defined by the home network specification; discovering, by the home access server, of functional components modules in the home network; upon selection of a functional component module through the control device, instantiation of generic user control protocol pages corresponding to said selected functional component module as a function of parameters of said selected functional component module. The invention also concerns a home access server device.
摘要:
A wireless Local Area Network (10) provides data service through a data LAN (14) and also provides video broadcast service through a video LAN (26). A wireless LAN subscriber accesses the video LAN through one of a plurality of Video Access Points (VAPs) (281 and 282) that broadcast multiple video programs on a channel having a frequency different than the frequency over which the subscriber accesses the data LAN. Each VAP maintains the video channel in a one-way broadcast-only mode to prevent a wireless LAN subscriber from seeking to uplink information on that channel. In this way, the wireless LAN can employ a common protocol for both data and video transmission, and deliver the video streams at the maximum permissible downlink transmission rate.
