The invention relates to a method for receiving and playing back audio and / or audiovisual content in a receiver device capable of receiving a determined audio and / or audiovisual stream from a unidirectional network or a bidirectional network. A determined stream broadcast on a network is first received and the content transmitted through said stream is played back in the receiver device.
