Abstract
The present invention provides an apparatus for evaluating video quality based on a hybrid type which, when bit stream data is received, extracts first evaluation parameters based on the received bit stream data to calculate a preliminary video quality score based on the first extracted evaluation parameters and then extracts second evaluation parameters, and calculates a final video quality score by adjusting the preliminary video quality score based on the second extracted evaluation parameters and methods thereof.
