Image encoding/decoding method and apparatus, and recording medium storing bitstream

A video encoding method, comprising:

• determining a current block;
• generating a bin for a first syntax element of the current block by binarizing the first syntax element;
• performing a determination on whether to perform an update on a context for the first syntax element;
• performing the update on the context for entropy encoding of the first syntax element based on determination;
• and
• generating a bitstream for the current block by using the context and the bin,
• wherein whether to perform the update on the context is determined based on the number of pre-encoded predetermined syntax elements for the current block.

A non-transitory computer-readable recording medium storing a bitstream, the bitstream comprising:

• information about a first syntax element of a current block, wherein
• the current block is determined,
• a determination on whether to perform an update on a context for the first syntax element of the current block is performed,
• the update on the context for entropy decoding of the first syntax element is performed based on the determination;
• and
• a bin for the first syntax element is generated based on the context, and
• whether to perform the update on the context is determined based on the number of pre-decoded predetermined syntax elements for the current block.
