Abstract (en)

[origin: WO2022263297A1] A part of a data stream comprises a plurality of data units (DU) respectively associated with a plurality of images and together representing different images of the plurality of images. Said data stream part further comprises differential coding data (Δ; Δ') of an artificial neural decoding network relative to a reference artificial neural decoding network. A method for decoding this data stream part comprises the following steps: - determining the artificial neural decoding network by decoding said differential coding data (Δ; Δ'); and - decoding at least one data unit (DU) of the plurality of data units by means of the determined artificial neural decoding network. Another decoding method, decoding devices, a computer program and associated data streams are also described.
