METHOD AND DEVICE FOR EMBEDDING AND DETECTING SYNCHRONIZING SIGNAL FOR SYNCHRONIZING AUDIO FILE AND TEXT

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for embedding in an audio file a synchronizing signal enabling a text to be synchronized and outputted when the audio file is reproduced. SOLUTION: Information regarding the size of a 1st part of a frame is obtained from a 2nd part of the frame first. Then the start position and size of a 3rd part of the frame are decided according to the obtained information and at least portions of the text signal and synchronizing signal are embedded in the 3rd part of the frame. The synchronizing signal can effectively be embedded in the audio file without impairing the contents of the audio file. COPYRIGHT: (C)2005,JPO&NCIPI
