Method And Apparatus For Correcting Video Signal

A apparatus of correcting a video signal that includes a decoded video sequence parameter, comprising:

• obtaining means for obtaining a specific number of decoded values of the video sequence parameter;
• counting means for counting the times of occurrence of each different value of the decoded values;
• determining means for determining a correction value from the counting result;
• and
• a correction module for correcting the decoded values of the video sequence parameter on the basis of the correction value.
