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.

Device for connecting a wireless network to at least one other network

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:

Method for linking several communication busses using wireless links

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: 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.

Method and device for address allocation for transmitting packets over a transparent bridge

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.

Method to prioritize videos distributed in a wireless LAN and device implementing the method

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.

Method of transmitting IEEE 1394 data over a wireless link and apparatus implementing the method

The invention concerns a method for managing resets in a communication network comprising wireless devices connecting busses over a wireless link, comprising the steps of: electing a parent wireless device among the wireless devices of the network, other wireless devices being labeled child wireless devices; having a first child wireless device send a bus reset message to the parent wireless device further to a reset on the child wireless device's local bus; having the parent wireless device spread the bus reset to other child wireless devices; having the other child wireless devices perform a bus reset on their local wired bus.

Method for managing a communication network comprising wireless links with more than two wireless devices

A method for connecting a device to a wireless network; at the level of a bridge device, configure to interface with the wireless network that maintains single management information. The bridge device separately registers, with respective MAC addresses, the device and itself as wireless devices on the wireless network.

Method and device for connection of a device to a wireless network

Method for isochronous data packet transport over a wireless network, comprising the steps of:

Method for isochronous data transport over a wireless network

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.

Method for reserving isochronous resources in a wireless network comprising at least a wireless source device and a wireless sink device, said wireless network being based on a TDMA frame transmission scheme, said method comprising the steps of:

Method for reserving isochronous resources in a wireless network

A method and device for implementing a method for associating communication devices capable of wireless interfacing. The method includes producing a relation between communication devices capable of wireless interfacing enabling dialogue among them exclusively. The devices comprise a single and permanent identifier, can be connected to a cable network and exchange data through the latter. The association can be modified by connecting the devices to be associated to a single cable network.

Communication devices capable of wireless interfacing and methods for associating said devices

The method comprises the steps of, representing the remote device on the cluster through the first wireless device and representing the devices of the cluster to the remote device through the second wireless device, such that the remote device and the devices of the cluster function as if these devices were part of a single IEEE1394 bus.

Method for connecting an IEEE1394 remote device to a cluster of IEEE1394 devices through a wireless link

The invention concerns a method for managing resources of a link in a communication network comprising busses interconnected by at least one link to form a network in which the at least one link is transparent for some protocol layers of nodes connected to the busses. The inventive method comprises the step of making information of the resources available over the at least one link available to link-aware applications.

Method for managing resources of a link in a communication network

A method for reserving an isochronous resource over a link between a first bus and a second bus, the link including a first interface device connected to the first bus and a second interface device connected to the second bus. The reservation of the resources over the link is transparent to the devices connected to the busses. The method includes, at the level of the interface devices, intercepting the connection set up messages sent by the devices connected to the busses, checking whether a source device and a sink device for which the set-up message has been intercepted are on different busses, and in the affirmative, reserving resources for the connection over the link.
