Abstract

For delivering an AV live content, time being divided into transmission periods, the AV live content being divided into chunks, a server performs: obtaining at least one multicast reference stream intended to transport one chunk per transmission period; obtaining at least one multicast side stream intended to transport, for each transmission period, a plurality of chunks which at least includes the same chunk as in each multicast reference stream and at least one preceding chunk; and synchronously transmitting each multicast reference stream and each multicast side stream along the transmission periods. A device willing to receive the AV live content performs: joining one multicast side stream for obtaining at least one chunk transmitted in a first transmission period; and switching to one multicast reference stream for obtaining subsequent chunks which are transmitted from a second transmission period following the first transmission period.
