Procedure and system for interception and reproduction of electronic information. On one hand, the system comprises a number of user units (1) which each one has a number of receiving and presentation units (10, 11) for audio and video, such as radio receivers and TV receivers, and on the other hand an operator structure (2) with a data base (20) connected to the user units and a number of transmitters (21) for electronically based information such as radio and TV programs, that may be received by the user units. In the operator structure (2), transmitted information is continuously stored together with an identification pattern, which is linked to the identity of the channel, the division of the information/programs into portions with different information contents and a time label. The user units (1) are equipped with a manoeuvring device (3), with which the determined program portion will be indicated to the data base (20) by means of the attached identification unit. Thus the indicated portion in the data base (20) is chosen for delivery to the user unit (1) in question, for presentation or storage. The manoeuvring device (3) is arranged to manually indicate the determined program portion chosen by means of some program schedule or alternatively indicate the ordered program portion by activating the manoeuvring device at a certain point of time during the on-going transmission.
