<p>The present invention relates generally to adaptive streaming and in particular to a method for delivering content via adaptive streaming technique over multiple communication paths and a device implementing the method. Thus, the present invention concerns a method for providing a content to be rendered at a client device CD, said content being accessible to the client device CD via at least two independent first and second paths P1, P2, said content being available under at least two versions having an encoding quality corresponding to a supported bit rate BRA, BRB constraint, each of theses versions being temporally split into chunks corresponding to an identical duration of the content, a chunk being identified by a temporal index i and by one of the supported bit rate BRA, BRB. According to the invention the method comprises the steps of:
S1 measuring by the client device CD a first available bit rate BR1 on the first path P1 and a second available bit rate BR2 on the second path P2;
S2 determining, by the client device CD, a requested bit rate RBR among the supported bit rate BRA, BRB from the measured first available bit rate BR1 and from the measured second available bit rate BR2;
S3 sending a first request via the first path P1, by the client device CD, for receiving a first part of the chunk identified by the index i and by the requested bit rate RBR and a second request via the second path P2 for receiving a second part of said chunk, said first and second part of the chunk being complementary;
S4 receiving by the client device CD the requested first part via the first path P1 and the requested second part via the second path P2.</p> |
