In this paper, the perceptual quality difference between scalable andsingle-layer videos coded at the same spatial, temporal and amplituderesolution (STAR) is investigated through a subjective test using a mobileplatform. Three source videos are considered and for each source videosingle-layer and scalable video are compared at 9 different STARs. We utilizepaired comparison methods with and without tie option. Results collected from10 subjects in the without "tie" option and 6 subjects in the with "tie" optionshow that there is no significant quality difference between scalable andsinglelayer video when coded at the same STAR. An analysis of variance (ANOVA)test is also performed to further confirm the finding.
