1. A method of decoding video data, comprising:
receiving, from a bitstream, multiple syntax elements at a sequence parameter set (SPS) level, wherein the multiple syntax elements are associated with a predefined function and sequentially arranged in the bitstream;
in response to a determination that at least one of the multiple syntax elements satisfies a predefined condition:
receiving, from the bitstream, a second syntax element after the multiple syntax elements;
in response to a determination that the at least one of the multiple syntax elements does not satisfy the predefined condition:
setting a value of the second syntax element to a default value; and
performing the predefined function for video data from the bitstream in accordance with at least one of the multiple syntax elements and the second syntax element, wherein the predefined function is one selected from a group consisting of an intra prediction function, an inter prediction function, and a merge mode.
