Abstract: A video decoding method and a video decoding device are provided, and the video decoding method includes the following steps. A to-be-decoded bin string is received. A plurality of first current syntax elements in the to-be-decoded bin string are decoded based on a first context model until a decoding output value of the last one of the first current syntax elements matches a specific bin pattern. When the first current syntax elements are decoded, in response to that a state machine is switched from a first decoding operation mode to a second decoding operation mode, a second current syntax element that exists based on the last one of the first current syntax elements is decoded.

Abstract: A video stream processing method and a video processing apparatus thereof are provided. The video stream processing method includes the following steps: obtaining a video stream, wherein the video stream is composed of a plurality of basic processing units; determining whether a size of the basic processing units is greater than a predetermined size; if the size of the basic processing units is greater than the predetermined size, determining whether each of the basic processing units has a coding-unit-splitting flag; splitting each of the basic processing units into a plurality of blocks according to the coding-unit-splitting flag or the type of each of the basic processing units, wherein a size of the blocks is equal to or less than the predetermined size; and, performing a video processing of the video stream according to the blocks.
