Abstract

Die Erfindung betrifft ein Gerät zur Erzeugung von Matrix-Surround-Raumklang aus Stereotonsignalen von Stereo-Tonquellen bzw. zur Erzeugung von Quasi-Stereoeffekten aus Mono-Tonsignalen von Mono-Tonquellen, wobei die Tonquellen, wie Fernsehgeräte, Videogeräte, Hifi-Geräte, Autoradios, PC-Soundkarten an interne und/oder externe Lautsprecher mit Verstärker angeschlossen sind, enthaltend einen als Phasenschieber-Matrix-Raum-IC ausgebildeten Dekoder und eine Steuereinrichtung für den Dekoder sowie Eingangsbuchsen für den Anschluß der Tonquellen und Ausgangsbuchsen für den Anschluß von über Verstärker betriebenen Lautsprechern, wobei als Steuereinrichtung für den Dekoder ein Rechner in Gestalt eines Mikroprozessors mit Adressteil mit Adresszwischenspeicher und Speicher, Resetteil, Fernbedienungseingang für eine Fernbedienung und gegebenenfalls einem zusätzlichen Speicher vorgesehen ist und der Rechner über einen Datenbus an den Dekoder angeschlossen ist, wobei der Datenbus im Multiplex-Verfahren betrieben wird.

Figure 00000001
The invention relates to a device for generating matrix surround surround sound from stereo sound signals from stereo sound sources or for generating quasi-stereo effects from mono sound signals from mono sound sources, the sound sources such as televisions, video devices, hi-fi devices, car radios PC sound cards are connected to internal and / or external loudspeakers with amplifiers, containing a decoder designed as a phase shifter matrix space IC and a control device for the decoder as well as input sockets for connecting the sound sources and output sockets for connecting amplifiers Loudspeakers, a computer in the form of a microprocessor with address part with address buffer and memory, reset part, remote control input for a remote control and possibly an additional memory being provided as the control device for the decoder and the computer being connected to the decoder via a data bus, the data bus i m is operated multiplex.
