Customer Adaptive Combined SNR and Spatial Scalability
A new type of region of interest (ROI) is proposed in this paper for scalable video coding with the whole region be the combined SNR and spatial scalability, and a sub-region be a specific choice of spatial resolution and bit rate range. The ROI is applied to design a combined SNR and spatial scalability scheme that is adaptive to customer composition such that an optimal customer oriented scalable tradeoff (COST) can be achieved. The profit can thus be maximized
