Information Hiding Algorithm of G.723.1 High-rate Speech Flow
摘要
Abstract
This paper studies the hiding method of the G723.1 high-rate speech coder which is used in streaming media communications, analyzes the hiding performance of Line Spectrum Frequency(LSF) parameters, then proposes the LSF parameters hiding performance analysis method based on critical bandwidth. By using the method of digital-position information, it proposes the information hiding algorithm of G723.1 high-rate speech flow. Experimental results proves the validity of the proposed algorithm.关键词
