The authors describe an optimisation algorithm which can be applied to two-layer SNR scalable MPEG-2 video coding, such that bandwidth efficiency is achieved which is comparable to single-layer coding. Our optimised two-layer coder is shown to generate as little as 1% fewer bits than a single-layer coder compared to up to 15% more bits generated by the non-optimised SNR scalable coder
