Video encoding method and apparatus

摘要

A video encoding method includes subjecting an input video signal to prediction processing according to a plurality of encoding modes to generate an syntax element for each of the encoding modes, accumulating the number of bits of intermediate binary representation of values of the syntax element before subjecting the syntax element to arithmetic encoding for each of the encoding modes, selecting one encoding mode from the plurality of encoding modes based on the number of bits, and subjecting the syntax element corresponding to the selected encoding mode to the arithmetic encoding.
