A joint source-channel coding (JSCC) approach for ATM-based network transport of scalable variable bit rate (VBR) digital video is described. We provide a new methodology for finding the optimum source and channel coding rates, together with the optimum data-partitioning ratio, to maximize the statistical multiplexing gain while maximizing the end-to-end video quality. The results provide a quantitative demonstration of the effectiveness of a scalable delivery approach over the single-layer JSCC.
