Abstract
A method and apparatus for evaluating video quality are disclosed. An apparatus for evaluating video quality according to an embodiment of the invention includes: an encoder unit that converts a first-resolution original video sequence into a second-resolution original video sequence and encodes the second-resolution original video sequence; decoder unit that generates a second-resolution decoded video sequence by decoding the encoded second-resolution video sequence and converts the second-resolution decoded video sequence into a first-resolution decoded video sequence by interpolating the second-resolution decoded video sequence to the first resolution; a video quality index calculator unit that calculates a first video quality index by comparing the first-resolution original video sequence with the first-resolution decoded video sequence and calculates a second video quality index by comparing the second-resolution original video sequence with the second-resolution decoded video sequence; and a video quality evaluator unit that calculates a final video quality index by using the first video quality index and the second video quality index.
