ENCODING AND DECODING METHODS AND DEVICES, AND CORRESPONDING COMPUTER PROGRAMS AND COMPUTER READABLE MEDIA

摘要

A method for encoding an image comprises the following steps: obtaining intermediate data representative of a base layer of said image encoded in a first compression format, the intermediate data being encoded according to a predefined data format allowing inter layer prediction of an enhancement layer of said image to be encoded in any of a plurality of second compression formats; generating a final bitstream by encoding the enhancement layer according to one of said second compression formats. A corresponding encoding method, as well as encoding and decoding devices, are also described.
