Afin de créer un système pour recevoir et enregistrer des signaux (Si) avec lesquels des programmes multiples peuvent être enregistrés simultanément sans dépenses correspondantes de matériel, ou des signaux (Si) pouvant être enregistré même si le dispositif d'enregistrement est momentanément indisponible, on met à disposition des moyens (1) afin de recevoir un premier signal (S1), et une mémoire (2) afin d'enregistrer le premier signal reçu (S1), dans laquelle se trouve un dispositif (6) de communication avec un réseau informatique (7), en particulier l'Internet. On trouve aussi dans le réseau informatique (7) un dispositif (8) de réception d'au moins encore un signal (S2), et un tampon (9) servant à enregistrer temporairement au moins un signal supplémentaire (S2), et, de plus, un dispositif (10) de transmission ultérieure d'au moins un signal supplémentaire (S2) du tampon (9) à la mémoire (2) par l'intermédiaire du réseau informatique (7).
