Abstract: Provided are methods and devices for encoding and decoding using parameter sets, and electronic equipment. In the method for encoding, an encoder determines parameter sets and/or virtual parameter sets for a slice, wherein the virtual parameter set is a data structure which is generated by loading information acquired from a bitstream into a syntax structure of an existing parameter set and/or a preset syntax structure and includes tool parameters and/or control parameters; and the encoder writes identification number (ID) (s) of the parameter sets and/or virtual parameter sets into a bitstream. Using the method, encoding and decoding efficiency is improved.
