Abstract:
The present invention relates to a method for receiving audiovisual programs sent by a server to at least two reception devices. Initially, a first user requests a document from the server that establishes a unicast stream to download said document. Then, a second user requests to receive the same document, even truncated by a part. The server studies the proposal and possibly, for a lower price, agrees to the download. The server then switches the broadcast of the document from a unicast stream to a multicast stream, the first and second devices receiving said document via the same multicast stream.The invention also relates to a device for receiving audiovisual content and a server for implementing the method.
