A fast synchronization pull-in and an optimum error correction are achieved in a reproduction apparatus for reproducing data recorded on a recording medium even in the case where the quality of input data involving a seek or defect is low. A seek amount detection block 190 is provided, a seek change signal 201 is generated, and the width of a synchronization detection window pulse 161 and a correction algorithm in a correction block 230 are modified.

摘要:
There is provided an environment adaptive type hearing aid capable of reducing the erroneous estimation of an ambient environment or the unnecessary changeover of a hearing aid process. The environment adaptive type hearing aid includes an input section (110) that inputs an ambient sound, a scheduled environment referring section (180) having a scheduled environment table (270) to store a scheduled environment candidate corresponding to an ambient environment other than the ambient sound set in advance for the hearing aid, an environment estimating section (200) that estimates an ambient environment candidate of the hearing aid on the basis of the ambient sound and estimates an estimation ambient environment on the basis of the ambient environment candidate and the scheduled ambient environment candidate, a hearing ability compensation system determining section (220) that determines a compensation system for the hearing aid on the basis of the estimation ambient environment, a hearing ability compensating section (130) that processes the ambient sound on the basis of the determined compensation system, and an output section (150) that outputs the processed ambient sound as an output sound.

摘要:
With the hearing aid device of the present invention, when the power is turned on, communication starts between the first and second hearing aids, and until this communication is established, it is recognized that the power has not been switched on to the second hearing aid, and the user is notified. Also, if the battery of the second hearing aid should die during use, a dead battery notification is sent to the first hearing aid, and if communication between the first and second hearing aids is blocked, the user is notified on the side of the first hearing aid that is operating.

摘要:
A demodulator 101 demodulates modulated data into demodulated data, detects a demodulation error, and sets an erasure flag. An error corrector 104 performs erasure correction for the demodulated data retained in a demodulated data memory 102 by using the erasure flag retained in an erasure flag memory 103. An erasure flag eraser 105 instructs the erasure flag memory 103 to erase an erasure flag which is set to the corrected demodulated data. In this way, the erasure correction which has a higher correction capability and is effective particularly for burst errors is realized.
