ABSTRACT:
The method embodying the invention uses a data transmission network between at least a server connected to data sources and a plurality of receiving and dialog peripherals for users. This network transmits the data in the form of a succession of digital data cells respectively associated with a virtual channel constituting a source/destination link for the data. In a first mode, each channel is associated with a respective previously compiled program whereas, in a second mode, a virtual channel is associated with each user, the latter being able to individually access and act on the different sources in order to compose the program he wishes to view. The invention applies notably to the distribution of data on board an aircraft.
