decoded, modified, and coded to obtain coded modified data. A
determination is made as to whether a satisfactory result will be
obtained by re-using the set of parameters, which had been
established for decoding the coded data, for decoding the coded
modified data. If so, the established set of parameters is added
to the coded modified data for decoding purposes. If a
satisfactory result will not be obtained by re-using established
parameters, a new set of parameters is added to the coded
modified data for decoding.
Claim 1 is illustrative of the invention and reads as
follows:
1. 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 (DEC1), 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 (ENC2) 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 (DEC2) the coded
modified data (CMD); and
