Abstract
A method and a system for encoding and decoding a digital image frame. Metadata representative of a value of at least one component of at least one pixel of the frame is generated in the course of applying an encoding operation to the frame. A standard compression operation is then applied to the encoded frame, as well as to the metadata, in preparation for either transmission or recording. At the receiving end, both the encoded frame and its associated metadata undergo standard decompression, after which the metadata is used in the course of applying a decoding operation to the encoded frame for reconstructing the original frame.
