A method is disclosed for delivering multimedia data streams to subscribers of a data distribution network in which a first number of data streams of different programs are fed into a head end and thence to different lower-level distribution points, in which these data streams are converted for transmission by an analog frequency-division multiplexing technique to a number of home terminations. Each of the terminals connected to the home termination can select one or more programs by selection of a frequency channel, and output this program or these programs to a user. In addition to the first number of data streams, the lower-level distribution points each receive a second number of data streams, and they retransmit data streams of this second number of data streams, together with data streams of the first number of data streams, as analog signals over given frequency channels to the respective home terminations connected thereto. Also disclosed are a data distribution network and distribution points for carrying out the method.
