A method for delivering content via adaptive streaming technique over multiple communication paths and a device implementing the method are disclosed.The method for providing a content to be rendered at a client device comprises at least a first past being identified by the address of a first interface and the address of a first server interface, and a second path being identified by the address of a second interface and and the address of a second server interface, the content being available under at least two versions having an encoding quality corresponding to a supported bit rate constraint, each of the at least two versions being temporally split into chunks corresponding to an identical rendered duration of the content, a chunk being identified by a time index i and by one of the supported bit rate.According to the invention the method comprises the steps of: measuring a first available bit rate on the first path and a second available bit rate on the second path; determining a requested bit rate among the supported bit rate from the measured first available bit rate and from the measured second available bit rate; sending a first request via the first path for receiving a first part of the chunk identified by the time index i and by the requested bit rate and a second request via the second path for receiving a second part of said chunk, said of the chunk being complementary; and each of said parts of the chunk having a size being computed from the determined available bit rate; receiving the requested first part via the first path and the requested second part via the second path.
