SIGNAL DECODING APPARATUS AND SIGNAL DECODING METHOD

Abstract A signal decoding apparatus that suppresses occurrence of big unusual sounds even when a transmission error occurs during decoding of scalable encoded information. In the signal decoding apparatus, an encoded information operating part (601) uses a transmission error detection bit to detect errors in basic layer encoded information, first expanded layer encoded information, and second expanded layer encoded information. A decoding control part (602) controls the on/off of control switches (606,607) in accordance with an error detection result and pattern information indicative of a bit rate pattern, and controls the sampling frequencies of sampling frequency adjusting parts (608,609). A basic layer decoding part (603), a first expanded layer decoding part (604) and a second expanded layer decoding part (605) perform decoding of the encoded information or frame loss compensations in accordance with the error detection result and bit rate. The sampling frequency adjusting parts (608,609) adjust the sampling frequencies of the decoded signals
