摘要：
A method of encoding video using intra prediction mode dependent quantization matrix includes: calculating an array of quantizers for each size of block unit (100); encoding the arrays of quantizers into header of compressed video stream (102); selecting one scanning order based on a selected intra prediction mode among a plurality of scanning orders (112); scanning the array of quantizers to obtain a block of quantizers based on the selected scanning order (114).
