Title: Surround signal processor and video and audio reproducing device
Inventor: IIDA TOSHIYUKI
IPC: H04S5/00
Filed: 1994-07-29
Abstract: PURPOSE:To generate surround effects by processing a monaural rear surround signal through simple constitution and reproducing it by a couple of speakers of a television receiver, etc. CONSTITUTION:The rear surround signal S is made into two irrelevant signals by an additional signal processing circuit OP. An adder 2 and a differentiator 3 generate a sum signal and a difference signal from the two signals. Filters 4 and 5 process the sum signal and difference signal. A sum signal and a difference signal are generated from the signals processed by the filters 4 and 5 and reproduced by the speakers SP1 and SP2. Transmission characteristics P and N of the filters 4 and 5 are set to P=(F+K)/(S+A) and N=(F-K)/(S-A). Here, S is transmission characteristics from the couple of speakers to the ear of a listener LM on one side and A is transmission characteristics to the ear on the opposite side; and F is transmission characteristics from a desired position where a sound image is localized to the ear of the listener on one side and K is transmission characteristics to the ear on the opposite side. Further, the signals are reproduced having differences (level difference, time difference, etc.) from a front signal.
