The invention relates to a method for receiving audio-visual programs transmitted by a server to at least two receiving devices. The inventive method consists in requesting a document by a first user from the server, which establishes a unicast flow for downloading said document, in requesting by a second user the reception of said document even partially truncated, in studying the proposal by the server which possibly reduces a price and allows the downloading, in switching the transmission of the documents from a unicast flow to a multicast flow by the server and in receiving said document by the first and second devices via the same multicast flow. A device for receiving audio-visual content and a server for carrying out said method are also disclosed. |
