Singnal processing device and recording medium
First Claim
1. A signal processing apparatus for processing an acoustic signal reproduced together with an image signal, the signal processing apparatus comprising:
- a memory for storing a plurality of filter coefficients for correcting the acoustic signal;
a filter coefficient selection section for receiving a correction command, from outside the signal processing apparatus, for specifying a correction method for the acoustic signal and selecting at least one of the plurality of filter coefficients stored in the memory based on the correction command; and
a correction section for correcting the acoustic signal using the at least one filter coefficient selected by the filter coefficient selection section.

Abstract
A signal processing apparatus for processing an acoustic signal reproduced together with an image signal includes a memory for storing a plurality of filter coefficients for correcting the acoustic signal; a filter coefficient selection section for receiving a correction command for specifying a correction method for the acoustic signal from outside the signal processing apparatus and selecting at least one of the plurality of filter coefficients stored in the memory based on the correction command; and a correction section for correcting the acoustic signal using the at least one filter coefficient selected by the filter coefficient selection section.

19. A recording medium, comprising:
-
an acoustic data area for storing an acoustic signal;
an image data area for storing an image signal;
a navigation data area for storing navigation data showing locations of the acoustic data area and the image data area; and
an assisting data area for storing assisting data, wherein;
acoustic signal correction data is stored in at least one of the acoustic data area, the image data area, the navigation data area, and the assisting data area, and the acoustic signal correction data includes at least one of a correction command for specifying a correction method for the acoustic signal and a filter coefficient for correcting the acoustic signal.
