This paper presents a rate control scheme for spatial scalability of H.264/SVC. At first, an adaptive method is proposed to decide the initial quantization parameter. Then, based on the transform coefficients distribution of spatial scalability, a new natural logarithm domain rate-distortion model is derived from the inspiration of the Cauchy-Density-Based model. Next, with above method and model, a rate control scheme is developed to match the characteristic of spatial scalability. The excellent performance of the proposed scheme is demonstrated by experimental results.
