Abstract
A method or device for reconstructing image data representative of original image data from decoded image data and parameters obtained from a bitstream is described. The parameters having been processed from the original image data. The method includes checking if parameters are lost, corrupted or not aligned with the decoded image data whose graphics or overlay is added to, when at least one of the parameters is lost, corrupted or not aligned with the decoded image data whose graphics or overlay is added to; selecting a recovery mode according to an information data indicating how the parameters have been processed; and recovering the at least one lost, corrupted or not aligned parameter by applying the selected recovery mode, the reconstruction of image data then taking also into account the recovered parameters.
