Title:
VOICE SYNCHRONIZATION REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JP3165661
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a processing time required for synchronization matching in a decoding processing skip in the unit of one voice frame in the case that reproduction of voice is largely delayed with respect to a reference time with respect to the voice synchronization reproducing device.
SOLUTION: A time information management means 104 of the voice synchronization reproducing device manages referenced time information and voice time information in the unit of one voice frame, and stops the processing of a voice decoding means 102 and a voice output control means 103 and issues a clear signal of data stored at present to a voice buffer memory 101 when the difference exceeds a prescribed threshold level. Thus, in the case that the voice synchronization is disturbed and reproduction of a voice is largely delayed from the reference time, data skip for plural voice frames is realized by aborting all data in the voice buffer memory 101 at once and the processing time required for synchronization matching is reduced.
