Method for encoding, method for decoding, and storage medium

A method for encoding, applied to an encoder, the method comprising:

• determining a prediction mode of a current block;
• determining at least one context model according to the prediction mode of the current block;
• determining a value of first syntax identification information, and performing binarization processing on the value of the first syntax identification information to determine a bin string of the current block, wherein the bin string comprises at least one binary symbol;
• and
• encoding at least one binary symbol in the bin string according to the at least one context model, and signalling obtained encoded bits in a bitstream.

A non-transitory computer-readable storage medium, having a computer program and a bitstream stored thereon, wherein the computer program, when executed by a processor, enables the processor to perform operations to generate the bitstream, wherein the operations comprise:

• determining a prediction mode of a current block;
• determining at least one context model according to the prediction mode of the current block;
• determining a value of first syntax identification information, and performing binarization processing on the value of the first syntax identification information to determine a bin string of the current block, wherein the bin string comprises at least one binary symbol;
• and
• encoding at least one binary symbol in the bin string according to the at least one context model, and signalling obtained encoded bits in the bitstream.
