1. A method for decoding a video signal, comprising:
receiving, by a decoder through a bitstream, arranged syntax elements in a sequence parameter set (SPS) level, wherein the arranged syntax elements in the SPS level are obtained by arranging and grouping syntax elements related to a predefined function into a group corresponding to the predefined function at a coding level, wherein the predefined function comprises intra tools or inter tools, and further comprises screen content tools, transform tools, quantization tools, loop filter tools, or partition tools;
wherein receiving the arranged syntax elements in SPS level comprises:
in response to a first syntax element in the arranged syntax elements satisfying a predefined condition, receiving a second syntax element in the arranged syntax elements immediately after the first syntax element; and
performing, by the decoder through the bitstream, the predefined function to video data from the bitstream in accordance with the first syntax element and the second syntax element.
