Abstract: The invention consists of a process for receiving and for screening audiovisual transmissions broadcast by a network. The transmissions consisting of events and of short transmissions possessing a distinctive element, these short transmissions being broadcast by services identifiable by this distinctive element. At a certain moment specified by the broadcaster, a sequence is transmitted on the network, it is replaced at the level of the display of the receiver by another sequence extracted from a service broadcasting short transmissions. The choice of this service is made at the receiver level. To avoid the appearance of a black screen between the network's transmitted sequences and the short transmissions, the receiver dispatches a filler transmission to the screen. The invention also consists of a digital television receiver for implementing the process.

The electronic device comprises a physical interface for removable connection to a host device, a processor and a usage time limit module with a counter. When the counter reaches a pre-determined value, the usage time limit module is configured to disable the electronic device, preferably by modifying the hardware of the electronic device, e.g. by disabling a communication line between the processor and the physical interface, which may be effected by blowing a fuse. The usage time limit module is powered by the host device via a power supply from the physical interface. In a preferred embodiment, the electronic device is a storage device. In a further preferred embodiment, the physical interface is a USB interface.

Abstract: Method for linking a first and a second communication bus through a wireless link, comprising a first portal connected to the first bus and a second portal connected to the second bus, said first and second portal communicating over a wireless connection. The method comprises the steps of: associating the two portals to the wireless network; exchanging, between the two portals of self identification packets of nodes connected to their respective local busses, including the self identification packets of the portals themselves; generating a reset on each bus; carrying out a self identification procedure on each bus, where each portal generates self identification packets for itself and for nodes of the respective remote bus, using the self identification packets received following the association step.

Abstract: The invention concerns method to distinguish between streams received by an access point from a distribution network and transmitted to stations and a way to give better priority to some of them towards others. In a system where streams are transmitted with a level of priority corresponding to there type, it adds a selection criterion to determine priority between streams of the same type. The invention also concerns an access point implementing the method.

Abstract: The invention concerns a method for transmitting packets in a network comprising at least a first sub-network and a second sub-network connected through a transparent communication link, said link comprising at least a first interface device connected to the first sub-network and a second interface device connected to the second sub-network. The method comprises the steps of: attributing a first set of addresses to the interface devices on the communication link; attributing a second set of addresses to nodes connected to the sub-networks, the attribution of the second set being done independently from the attribution of the first set; checking whether there appears a conflict between an address of the first set and an address of the second set, and in the affirmative: changing the conflicting address of the first set to a non conflicting address. The invention also concerns a device for implementing the method as well as a method for detecting and transmitting packets to be transmitted over the link.

Abstract: The invention relates to a method of transmitting data over a wireless link, comprising the insertion of the data into packets according to a format corresponding to at least certain layers of a first protocol for data transmission over a wireless network, as well as the use of these packets to form a frame in accordance with a second protocol for data transmission over a wireless network, different from the first protocol, and the transmission over the wireless network according to the second protocol. The invention also relates to the apparatus implementing the method.

Abstract: Within the framework of a wireless local area network, the sending of the multipoint transmission streams is not made reliable by an acknowledgment of receipt mechanism. This reliability may be improved by the sending in point-to-point mode of the packets belonging to a multipoint transmission stream. In the case of a digital service consisting of several streams of different priorities, it is possible to send only some of these streams in point-to-point mode while the other streams remain in multipoint. A gateway between the local area network and the exterior may be tasked with this selective transformation of the mode of transmission of the streams received.
