MPEG Surround Encoder with Steganography Feature for Data Hiding Based on LSB Method

Spatial audio coding becomes more important for future audio technology as the Ultra High Definition TV (UHDTV) is ready to enter the market, which is particularly pioneered by engineers in Japan. In this work a method of audio data hiding (steganography) is proposed to be integrated in an MPEG Surround (MPS) encoder, a standard based on the principle of spatial audio coding. A new Reverse One-To-Two (R-OTT) module is introduced with a capability of hiding a short important and secret data or information. This information is embedded in the least signi?cant bit (LSB) of the spatial parameter of the MPS bit stream. The experiments show that the embedding data do not significantly decrease the quality of the transmitted audio signals.
