Abstract
A matrix surround decoding system comprises a DIR 10 detecting a sampling frequency FS included in a stereophonic source, and a microcomputer 12 determining the type of stereo source on the basis of the sampling frequency detected by the DIR 10, and outputting to a matrix surround decoder 11 a mode switching signal CL for switching the output mode of the matrix surround decoder 11 to a mode corresponding to the determined type of stereophonic source.
Claims4
A matrix surround decoding system including a matrix surround decoder to expand a two-channel stereophonic source to a multichannel source for reproduction, comprising:
- a sampling frequency detecting member detecting a sampling frequency included the stereophonic source;
- and
- an output mode switching member determining a type of the stereophonic source on the basis of the sampling frequency detected by the sampling frequency detecting member, and outputting to the matrix surround decoder a mode switching signal for switching an output mode of said matrix surround decoder to a mode corresponding to the determined type of the stereophonic source.
