METHODS, APPARATUSES, COMPUTER PROGRAMS AND COMPUTER-READABLE MEDIA FOR PROCESSING CONFIGURATION DATA

Document Type and Number:

WIPO Patent Application WO/2020/089614

Kind Code:

A3

Abstract:

For each image in a set of images (310), residual data is obtained based on first and second representations of the image at a first level of quality. The second representation is based on a representation of the image at a second, lower level of quality. The residual data is useable by a decoder to reconstruct, for each image in the set (310), the first representation using the second representation. One or more configuration parameters (320) of configuration data relating to processing of the residual data: (i) are obtained, (ii) are useable by the decoder to reconstruct the first representation for each image in the set (310), and (iii) correspond to multiple images in the set (310). The one or more configuration parameters (320) are output for processing by the decoder. The number of times the one or more configuration parameters (320) is output for the set (310) is less than the number of images in the set (310).
