Abstract—JPEG XR is an emerging image coding standard, based on HD Photo developed by Microsoft technology. It supports high compression performance twice as high as the de facto image coding system, namely JPEG, and also has an advantage over JPEG 2000 in terms of computational cost. JPEG XR is expected to be widespread for many devices including embedded systems in the near future. This review-based paper proposes a novel architecture for JPEG XR encoding. This paper gives discussion of image partition and windowing techniques. Further frequency transform and quantization is also addressed. A brief insight into Predication, Adaptive Encode and Packetization has been provided in the paper.

Index Terms—JPEG XR, encoder, PCT, quantization, adaptive prediction, adaptive entropy coding.
