METHOD AND APPARATUS TO CONTROL A MULTIPATH ADAPTIVE STREAMING SESSION
First Claim
1. Method to control the transmission between at least two servers and a receiver, said servers being adapted to transmit data representative of an audiovisual content, said audiovisual content being available from each of said at least two servers in at least two versions, said versions corresponding respectively to different transmission bit-rates, said at least two servers being adapted to transmit said audiovisual content in successive parts, each of said successive parts being chosen as a part of one of at least two versions from one of said at least two servers in response to transmission requests sent by said receiver, said transmission requests comprising at least a transmission parameter, said method comprising at a controller the steps of:
- reception of information from a receiver, said information being representative of the delivery of said audiovisual content from one of said at least two servers to said receiver,transmission of a control parameter to said receiver said control parameter being computed from at least said information in order to define from said control parameter said at least one transmission parameter.

Abstract
The present invention concerns a method to control the transmission and transmission data rate between at least two servers and a receiver. The servers being adapted to transmit data representative of an audiovisual content. The audiovisual content being available from each of said at least two servers in at least two versions. The versions corresponding respectively to different transmission bit-rates. The servers being adapted to transmit audiovisual contents in successive parts, each of said successive parts being chosen as one of at least two versions in response to transmission requests sent by the receivers, said transmission requests comprising a transmission parameter.
