Abstract: Disclosed is a multimedia server on-board an aircraft including: a database including a permanent part and a temporary part, the temporary part being empty each time the aircraft takes off; a module for receiving a request from a terminal including a playback request for a multimedia file of interest; a processing module configured for checking whether the multimedia file of interest is present in the database; an external communication module configured for sending the request to an external system when the multimedia of interest is not present in the database and for receiving the multimedia file of interest and for storing same in the temporary part; and a module for sending the multimedia file of interest to the terminal.

Abstract: A media server for an on-board entertainment system comprising terminals, the server comprising: a memory for storing media content; a distribution module configured to distribute stored media content to terminals; a controller for controlling the storage of media content in the storage module; wherein the controller is configured to collect the numbers of accesses via the terminals to the media content, to calculate the value of a retention parameter relating to each item of media content as a function of said number of accesses, and to automatically trigger the continued retention of said media content in the memory or its deletion as a function of at least said calculated value.

Abstract: The present invention relates to an allocation method in a transmission network on-board a mobile vehicle, the network comprising wireless access points configured for transmitting and receiving, over a functioning channel, radio signals between said access point and a plurality of terminals. The method comprising the following steps: provision of a digital model of the mobile vehicle and of the access points; for every available channel and for every access point, simulation of the propagation of signals from said access point on said available channel; for every available channel, for every access point and for every terminal, determination of an estimated associated bandwidth according to the simulation; allocation of one of the available channels and one of the access points to every terminal according to the estimated bandwidths.

Abstract: A method of storing data in a memory of a server comprising the following steps: partitioning the memory into separate partitions; receiving content and storing said content in one of said partitions; a number, called the number of replications, is associated with each partition; distinct numbers of replications being associated with distinct partitions; a number of replications n of said received content having been defined for said content, selecting a partition with which said defined number n of replications has been associated, storing said content comprising the storing of n replications of said content in said selected partition.

Abstract: The present invention exploits the multiple-broadcast capabilities of networks associated with a reliable connection-oriented protocol. The inventive method allows a file to be transferred only once. The data, which represent a large volume of information, use multiple-broadcast channels, whereas the interchanges relating to the control of the quality of the communication use a reliable medium in connected mode. In order to eliminate the unnecessary transfers (network) and activity (server and client), a calculation worked out from all of the file data is performed to identify it definitely.
