<p>The invention concerns a method characterized in that it comprises the following steps: reducing the bit stream (2) which consists in suppressing one or several video packets in the bit stream to supply a reduced bit stream; implementing an error masking algorithm on the reduced bit stream (3) to calculate a corrected degraded local decoded image which is the image reconstructed from the reduced bit stream and the masking algorithm; a validating step (4) to validate or not the bit stream reduction based on the quality of the corrected degraded local decoded image; selecting (2) the reduced bit stream or the bit stream, depending on whether or not there is validation.</p> |
