1. A method of encoding video data, the method comprising:
obtaining a parameter set associated with a non-skip mode coded block;
in accordance with a determination that the parameter set includes information that satisfies a first condition, signaling a first syntax element in a bitstream;
in accordance with a determination that the parameter set includes information that satisfies a second condition, signaling a second syntax element in the bitstream;
in accordance with a determination that the parameter set includes information that satisfies a third condition, signaling a third syntax element in the bitstream;
encoding video data corresponding to the non-skip mode coded block using palette mode when the first syntax element has a first value and the third syntax element has the first value;
encoding the video data corresponding to the non-skip mode coded block using intra prediction mode when the first syntax element has the first value and the third syntax element has a second value;
encoding the video data corresponding to the non-skip mode coded block using inter prediction mode when the first syntax element has the second value; and
transmitting the video data corresponding to the non-skip mode coded block via the bitstream.
