<P>PROBLEM TO BE SOLVED: To provide a surround-sound system performing a digital radio transmission to rear voice which can prevent a generation of a noise and a sound interruption due to an external noise and a fault of a transmission line and which can reproduce an original surround-sound effect. <P>SOLUTION: In the surround-sound system having a voice signal decoder 5 separating a voice signal reproduced by a video reproducing device 1 into a front voice signal and a rear voice signal, a front side voice reproducing system amplifying the front voice signal to be outputted as a front side voice from a front speaker, and a rear side voice radio reproducing system amplifying the rear voice signal after being transmitted by air to be outputted as a rear side voice from a rear speaker, an error detection/correction circuit 24 correcting a code error of the rear voice signal transmitted by air, and a front voice signal delay circuit 6 delaying the front voice signal from the voice signal decoder 5 by delay time almost the same as the delay time by which the rear voice signal is delayed by the error detection/correction circuit 24 are provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
