Patent ID: 6895053

Claim:
A method of modifying coded data (CD) which is accompanied by a set of parameters (PAR) for decoding the coded data (CD), the method comprising the steps of: decoding (DEC 1 ), at least partially, the coded data (CD) so as to obtain decoded data (DD); modifying (MOD) the decoded data (DD) so as to obtain modified data (MD); coding (ENC 2 ) the modified data (MD) so as to obtain coded modified data (CMD); examining (EXAM) whether a satisfactory result will be obtained, if the set of parameters (PAR) for decoding the coded data (CD) is applied for decoding (DEC 2 ) the coded modified data (CMD); and adding (ADD) to the coded modified data (CMD) the set of parameters (PAR) for decoding the coded data (CD) if the result is satisfactory or, if the result is not satisfactory, establishing (ADP) a new set of parameters (APAR) and adding (ADD) the new set of parameters (APAR) to the coded modified data (CMD).
