<p>A method for providing data (DS, DS', DS") from a server to a plurality of end-users (R1, R2, R3) via a communication network, comprising the steps of:
- starting a transmission of the data (DS) to at least a first end-user (R1, R3);
- while transmitting the data to the first end-user, upon a detection of a request for a transmission of the same data by at least one second end-user (R2), establishing a multicast transmission of the data to the first and the second end-users;
- requesting missing data (MP) not received with the multicast data at the second end-user from the server.</p> |
