Title:
VIDEO DECODING METHOD FOR PERFORMING REDUCED DYNAMIC RANGE TRANSFORM WITH INVERSE TRANSFORM SHIFTING MEMORY
Document Type and Number:
Japanese Patent JP2016192789
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce a dynamic range of image decoding.SOLUTION: A method for decoding video includes a step of receiving quantized coefficients indicating a block of the video showing a plurality of pixels. The quantized coefficients are de-quantized on the basis of a function of a remainder. The de-quantized coefficients are inverse transformed to determine a decoded residue.SELECTED DRAWING: Figure 3A
