Abstract: Method of setting up a communication session between a calling client (C1) and a called client (C2), through a communication network (SN1, SN, SN2) containing at least one address translation device (NAT1, NAT2). This method contains stages for the transmission of signaling messages (fs), passing through at least one address translation device and allowing the exchange of the physical addresses of the clients. At least one of the clients implements a solution for the traversing of address translation devices. The method is innovative in that at least one client adds, within the sent signaling messages, a parameter representing the implementation of the traversing solution and that, in the presence of such a parameter, the network devices do not implement their own solutions for the traversing of address translation devices.

Abstract: The invention pertains to a method for transferring multimedia data (9) over a network (1) comprising several terminals (3, 5, 7) linked to at least one storage device (11), consisting of the following steps: One selects a source terminal (5) playing multimedia content by using a mobile interface terminal (3), One selects a sequence of multimedia content being played from among the available multimedia content, One identifies a target terminal (7), One assesses the compatibility of the data (9) with the selected target terminal (7), Where applicable, one transfers the selected data (9), or the data converted from the selected data (9), to the target terminal (7) through the network (1).

Abstract: Method of setting up a communication session (fm) between a calling communication client (C1) and a called communication client (C2), through a communication network (SN1, SN, SN2) comprising at least one address translation equipment (NAT1, NAT2). It comprises steps for transmission of signal messages (fs), transiting through address translation equipment and enabling interchange of physical addresses of communication clients to set up the communication session. This method is characterized in that at least one client transmits at least one signal message containing a physical address in a first location, and coded information containing this particular physical address in a distinct second location.

Abstract: The invention relates to a method for securing the operation of a gadget requiring access to features hosted in a library of a gadget container (36) in order to implement these features into a primary file (35) of such gadget, the primary file (35) being sent by a Web hosting server (40) to the gadget container (36) to allow the implementation of the features with the primary file (35), wherein: —the gadget container (36) retrieves the primary file (35) of the gadget from the Web hosting server (40) with a signature (16), based on a public key/private key encryption system, associated therein,—the gadget container (36) verifies, with a public key of the public/private key encryption system, the signature (16) associated to the gadget primary file, —the gadget container (36) decides to authorize or to refuse the implementation of its library (44) features depending on whether the signature (16) associated with the primary file (35) is accepted or refused.
