Abstract

A digital home audiovisual Information recording and playback apparatus includes a microprocessor associated, through a digital interface, with a display, through another interface with sound playback structure and through a telecommunications interface with structure for loading audio selection or visual selection digital information. The system includes structure for controlling the display, enabling an operating mode to be selected from a menu of three modes, in which the device either plays back information stored in its mass memory, records new digitized information in its mass memory or combines analog information from a microphone with digitizer information received from the mass memory.
