Virtual Source Location Information Based Matrix Decoding System
In this paper, a new matrix decoding system using vector based Virtual Source Location Information (VSLI) is proposed as one alternative to the conventional Dolby Pro logic II/IIx system for reconstructing multi-channel output signal from matrix encoded two channel signals, Lt/Rt. This new matrix decoding system is composed of passive decoding part and active part. The passive part makes crude multi-channel signals using linear combination of the two encoded signals(Lt/Rt) and the active part enhances each channel regarding to the virtual source which is emergent in each inter channel. The virtual sources between channels are estimated by inverse constant power panning law.
