Method for the synchronized broadcast of data streams, wherein at least one stream of processed data in the form of signals is transmitted from a transmission source to at least two remote receivers (3, 3',...) for broadcasting said stream (s), with said receivers (3, 3',...) each comprising at least one internal electronic clock, and a calendar clock, and said source comprising a reference calendar clock clocked by an internal electronic clock, consisting of: - clocking the calendar clock of said receivers (3, 3',...) by means of said internal electronic clock; - estimating the time differences between each receiver (3, 3',...)on the one hand and said source on the other hand, by exchanging and comparing between each receiver (3, 3',...) and said source signals timestamped by the calendar clock of each receiver (3, 3',...) and the calendar clock of the source; - adjusting the time of the calendar clock of said receivers (3, 3',...), by directly modifying its internal values, where there is a difference greater than a predefined value between the times of the calendar clock of each receiver (3, 3',...) and of the reference calendar clock; - estimating the transit time between said source and each receiver (3, 3',...), to correct the estimate of the time differences; - adjusting the internal electronic clock of each receiver (3, 3',...) according to said estimate of the time differences with the source, by increasing or reducing its frequency, with the aim of eliminating these time differences; - clocking the data processing units of said receivers (3, 3',...) by means of said internal electronic clock or a dependent correlated electronic clock; and - stamping said data at said source; so as to make the calendar time of each receiver (3, 3',...) identical to the reference calendar time of the source, and therefore make the calendar times of all the receivers (3, 3',...) identical to one another, and to synchronize the processing and broadcasting at each receiver (3, 3',...) of said stamped data. - clocking the calendar clock of said receivers (3, 3',...) by means of said internal electronic clock; - estimating the time differences between each receiver (3, 3',...)on the one hand and said source on the other hand, by exchanging and comparing between each receiver (3, 3',...) and said source signals timestamped by the calendar clock of each receiver (3, 3',...) and the calendar clock of the source; - adjusting the time of the calendar clock of said receivers (3, 3',...), by directly modifying its internal values, where there is a difference greater than a predefined value between the times of the calendar clock of each receiver (3, 3',...) and of the reference calendar clock; - estimating the transit time between said source and each receiver (3, 3',...), to correct the estimate of the time differences; - adjusting the internal electronic clock of each receiver (3, 3',...) according to said estimate of the time differences with the source, by increasing or reducing its frequency, with the aim of eliminating these time differences; - clocking the data processing units of said receivers (3, 3',...) by means of said internal electronic clock or a dependent correlated electronic clock; and - stamping said data at said source;
