Abstract: The present invention concerns a content server device and a content receiver device, and a method at said devices for sending content in a robust mode. In particular the invention concerns a method at a peer to peer client to receive content from a server, the method comprising the steps of receiving content from a server in a multicast mode, indicating to the server the content that has been correctly received, receiving from the server in a multicast mode a content availability map indicating the content available at each peer and requesting the missing content from the peer indicated in the content availability map.

Abstract: The present invention concerns a method for downloading content using a combination of push and pull modes. In a communication system comprising a first terminal, at least a second terminal, and a content server, the invention concerns a method for downloading content comprising, at the level of the first terminal, the steps of downloading content either in a pull mode from the content server or at least the second terminal or in a push mode from the content server; and seamlessly switching between the modes for continuing downloading of the content.

Abstract: The present invention relates to a method of fabricating a nanostructure, comprising the following steps: prestructuring a substrate (1) adapted to receive the nanostructure to form a nanorelief (2) on the substrate, the nanorelief having flanks (4) extending from a bottom (1a) of the substrate and a top face (3) extending from said flanks, and then depositing on the substrate pre-structured in this way a single layer or multilayer coating intended to form the nanostructure; and further comprising: adding to the prestructured substrate or to the coating a separation layer adapted to enable separation of the coating and the substrate by external action of mechanical, thermomechanical or vibratory type; and exerting this external action on the substrate and/or the coating to recover selectively a top portion of the coating by separating it from the top face of the nanorelief so that this top portion constitutes some or all of the nanostructure.

Abstract: The present invention concerns a file repair method for recovering a file, in a system for distributing content to more than one receiver, comprising, at a first receiver, the steps of receiving a set of files in a push multicast from a transmitter, receiving an identifier of a second receiver that owns a missing file that is not comprised in the received set of file; and recovering the missing file from the second receiver in a pull mode using a peer-to-peer mechanism. Another object of the invention is a method for file recovery in a server and in a peer device.

Abstract: The invention concerns a method enabling different software versions addressed to different decoders to be mixed in a common stream. The principle consists in defining a unique data format enabling a decoder to be updated from a stream transporting the binary segments of several software versions of the resident software, said binary segments consisting of segments common to several software versions of the resident software, said binary segments consisting of segments common to several software versions and segments specific to each of the software versions.

Abstract: The invention relates to a method of receiving audio/video services comprising a step of transmitting a name resolution request according to an audio/video services entry point discovery protocol. In order to allow access to varied services, the method comprises: steps of receiving first and second addresses corresponding to, respectively, a first and a second entry point used for distributing service signalling, the addresses being provided by, respectively first and second name servers associated with distinct networks a step of storing the first and second entry point addresses.

Abstract: The present invention relates to a method of transmitting audiovisual streams between at least one device controlled by a user and a server. The audiovisual streams specified by the requests from the user are displayed on the device. The user enters a first command to change stream to the server in order to set up a communication for the transmission of the determined stream. The server then creates the determined stream and at least one second stream with a reduced bandwidth. This second stream corresponds to a stream that is immediately accessible by a second command from the user. The invention also relates to a receiver and a transmitter for implementing the method.

Abstract: Method for detecting and for quantifying adenoviruses by polymerase chain reaction (PCR). The method makes it possible to detect, in a single reaction, the various adenovirus serotypes and to quantify very low amounts.

Abstract: The invention relates to a process for transmitting and a process for receiving update data. According to the invention, the update data are dispatched by a communication center to terminals with the aid of a broadcasting network. Next, the terminals report their update to the center through a bidirectional network. The center renews the campaign or stops the current campaign as a function of the number of terminals updated. When only a minimum number of terminals to be updated remains, the campaign is stopped, the last terminals not updated will be so via the bidirectional link.
