摘要： Provided is an encoding and decoding method and device for data compression. The encoding method includes: adaptively selecting a constrained string mode from a plurality of preset constrained string modes; and performing, according to the selected constrained string mode, string-matching encoding on a coding block to obtain information of a constrained string encoded in the selected constrained string mode and to obtain a bitstream of a syntax element of the constrained string encoded in the selected constrained string mode.
