Claim 12:
13. A method for video coding, comprising:
obtaining a predicted image block;
obtaining a first residual image block according to the predicted image block and an original image block;
transforming and quantizing the first residual image block to generate a quantized block for writing a code stream;
inverse quantizing the quantized block to generate an inverse transform block according to the method of any of claims 1-12;
inverse transforming the inverse transform block to generate a second residual image block;
obtaining a reconstructed image block according to the second residual image block and the predicted image block;
deblocking filtering the reconstructed image composed of the reconstructed image block to obtain a reference image provided to subsequent frame references.
