Abstract
Embodiments of the disclosure provide a coding method, an encoder, and a decoder. The decoder decodes a bitstream to determine a context mode flag of a current block, determines an initial value of a quantity parameter according to the context mode flag, and determines coefficients of the current block using at least one of a context mode or a bypass mode according to the initial value of the quantity parameter. The encoder determines the context mode flag of the current block, determines the initial value of the quantity parameter according to the context mode flag, and encodes the coefficients of the current block using at least one of the context mode or the bypass mode according to the initial value of the quantity parameter to generate the bitstream.
