Abstract:
1. Method for transmitting information enabling a synchronization of applicative clocks signals between an emitter device and at least one receiver device which communicates via a communications network, said emitter device performing the following steps: receiving pieces of applicative data from a source application, at a data rate defined by a source applicative clock, and transmitting said pieces of applicative data via said network, at a data rate defined by a network clock, the network clock being independent of the source applicative clock; wherein said emitter device performs the following steps upon detection of a clock adjustment event: determining a piece of time offset information between a reference instant of a current network cycle and an instant relative to the reception of a reference piece of data among said pieces of applicative data; determining a piece of information on a position in memory, of said reference piece of data that has been used to determine the piece of time offset information, among the pieces of applicative data to be transmitted via said network during a determined network cycle; transmitting, via said network, said information on time offset and position during said determined network cycle; and wherein said clock adjustment event is periodically generated according to a predetermined period that is a function of requirements on a jitter and maximum frequency drift authorized by said source application generating said applicative data.
