PROBLEM TO BE SOLVED: To reduce the quantity of information to be sent to a set of user devices related to a multiuser interactive virtual environment from a server. SOLUTION: One set of servers composed at least of one server 100 uses a reception filter for an input data stream so as to discriminate one set of user devices composed at least of one user device 102 to which an output message is set. The output message represents the input data stream. The second user device 106 contained in a set of user devices 102 is related to second entity. The second entity occupys second position in the multiuser interactive virtual environment. A set of servers composed at least of one server compresses the input data stream based on one set of features composed at least of one feature for generating the output message. Finally, a set of servers composed at least of one server transmits the output message to the second user device 106.
