Decoding method, encoding method and related devices

Abstract

Embodiments of the present application provide a decoding method, an encoding method and related devices. The decoding method can include: receiving an encoded signal and an encoded global feature; deriving reconstructed global semantics from the encoded global feature by using a global decoding model; deriving prediction information from a series of decoded signals by using a prediction model; deriving context information corresponding to the encoded signal from the reconstructed global semantics and the prediction information by using a context extraction model; and decoding the encoded signal according to the context information by using a signal decoding model. The proposed technical solutions are expected to improve the decoding and encoding efficiency and quality.
