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.

Abstract: Provided is a method for encoding parameter sets at slice level. The method includes: when there are one or more parameter sets, in which the coding tool parameters are identical to the coding tool parameters of a part of coding tools used for the current slice, in the existing parameter sets, encoding the identifiers of parameter sets into bit-stream of the current slice, wherein a parameter set contains common information of the coding tools used in the process of encoding/decoding slice(s). Correspondingly, also provided is a method for decoding parameter sets at slice level and a device for encoding and decoding parameter sets at slice level, which can make full use of the encoded parameter set information when the slice header refers to a plurality of parameter sets, implement flexible configuration of the coding tools used in the process of encoding/decoding slice(s) and reduce information redundancy.
