Abstract: The invention relates to a method for allocating a data stream in a system comprising at least one service for broadcasting data stream, at least one server and at least two terminals, the one at least of said two terminals being able to receive a same program from at least two different sources, characterized in that said method comprises steps for: the reception, by said server, of a transmitted message by at least one first terminal, said message comprising an information indicating that said first terminal cannot receive a data stream identifying a source and a program, called first program that was asked for by request, the arbitration, by said server, of sources of said streams during transmission of programs to said terminals and of said request, the notification for the change of source to at least a second terminal to which the broadcasting service broadcasts a program, called second program, in order to meet the request of the first program of said first terminal.

Abstract: The invention provides the use of a water-soluble biocide as an uncoupling agent at an effective amount to control bacterial biomass in an aqueous system. The invention also provides a method for controlling the growth of bacterial biomass in an aqueous system. The method comprises adding to, or contacting with, the aqueous system an effective amount of an uncoupling agent which is a water-soluble biocide. In a preferred embodiment the method comprises contacting an effective amount of an uncoupling agent which is a water-soluble biocide directly with the bacterial biomass in an aqueous system.
