Abstract
An improved method and configuration for operating a network containing a personal video recorder server having measures for receiving several digitally encoded TV channels, for feeding several terminals and for recording storable TV programs. The terminals have measures for selecting storable TV programs and measures for transmitting the choice to the PVR server. The configuration contains a first database in which the index of TV programs stored by the PVR in response to the selection produced by the terminal is recorded. The first database controls authorization or refusal to play back the stored programs on the terminal. A second database stores, for the first terminal, the other terminals authorized to play back the TV programs selected by the user of the first terminal or all TV programs associated therewith by the first data base index. Terminals that are not contained in the second database are not authorized.
