Writing on dirty paper, a mathematical model for watermarking, is examined and extended to allow simultaneous watermarking at multiple rates. Based on the extended model, it is argued that the optimal watermarking strategy is to share the power. The argument is further supported by simulations of joint spread spectrum and quantization watermarking.
