英文摘要： Multiple Description Coding (MDC) has shown its efficiency to solve the packet losing and network delay problems in wireless communication in recent years. With the more and more attention has been paid on the efficiency and the information security techniques of transmission, the combination of the Multiple Description Coding and the information security techniques takes a more important place. Our research here focues on the combination of the image MDC techniques and the watermarking techniques which can not only improve the performance of real-time transmission, but also it can enhance the security of the transforred information. So it has an important theoretical and practical significance in this area. In this project, the main research content includes: (1)To study the combination algorithms of the quantization based MDC frame and the watermarking techniques. (2) To study the combination algorithms of the transformation based MDC fame and the watermarking techniques. (3) To study the combination algorithms of the wavlelet transform based MDC frame and the watermarking techniques. (4) To biuld MDC watermarking frames which are under the wavelet image coding standards and to test the proposed algorithms through the experimental results.
