A method for coding high dynamic range video sequences is considered. The technique is scalable, in that it facilitates the simultaneous transmission of standard and high dynamic range versions of the sequence in a single bit-stream. Furthermore, the approach is backwards compatible with the existing, state-of-the-art, AVC|H.264 video coding standard.Emphasis is placed on improved coding efficiency as well as managed computational complexity. Results illustrate the efficacy of the approach.

Resampling is a fundamental issue in the design of a spatially scalable video codec. The resampling procedure is responsible for down-sampling the high-resolution video sequence to generate lower resolution data, as well as upsampling the transmitted lower resolution data to predict the original high-resolution frames. In both cases, the resampling operation must make trade-offs between coding efficiency, image quality and computational complexity. In this paper, we consider the resampling design problem within an optimization framework.
