Abstract: Provided is a method of assessing an image quality of each of a base layer and an enhanced layer using a different scheme to assess a quality of a multi-level video based on assessment results. A multi-level video quality assessing system includes: a bitstream extractor to separate a multi-level video into a base layer bitstream and an enhanced layer bitstream; a base layer quality assessment module to generate quality assessment result information of a base layer image by assessing an image quality of base layer bitstream; an enhanced layer quality assessment module to generate quality assessment result information of an enhanced layer image by assessing an image quality of enhanced layer bitstream; and a final video quality assessment module to assess a quality of experience (QoE) of multi-level video based on quality assessment result information of each of the base layer image and the enhanced layer image.
