• Asymmetric data structure
• Codec
• Data-hiding communication
• Side information
• Transmission rates

Data structure is one of the key technologies for real-time information-hiding communication system. Therefore, the system design should be a related problem between source statistics and channel state as well as transmission rates. To satisfy some requirements with side-information at decoder, the paper presents a new method to approach information-hiding communication performances with asymmetric data structure. By means of variances distribution of image coefficients and channel states under various WNR, the proposed method can reduce system complex. Comparing the theoretical results by experimentation considered SCS and QIM (DC-DM) as well as SS techniques, the communication system possess the good trade-off performances.
