Abstract
A method for delivering content to at least two terminals for synchronous playback is described. The method includes providing a first association of content to a preamble sequence, providing a second association of content to an ending sequence, providing estimations of data delivery duration from a server to at least two terminals and a playback duration of the preamble sequence in at least one of the first and second association, delivering the first and second association to the terminals wherein the playback duration of the preamble sequence is greater than or equal to the largest difference between the estimations, and wherein the estimations of data delivery duration allows each of the at least two terminals to evaluate a local temporization duration for playing-back synchronous content.
