Assessment of the Quality of Video Sequences Performed by Viewers at Home and in the Laboratory

The paper presents the results of subjective and objective quality assessments H.264-, H.265-, VP9-encoded video. Most literature is devoted to assessment in well-defined laboratory circumstances. However, end users usually watch films their home environments, which may be different from conditions recommended for measurements. This cause significant differences scores. Thus, aim research show impact environmental on video perceived by user. was made two environments: users’ homes, where people often movies laptops. signal assessed young viewers who were not experts field assessment. tests performed taking into account image resolutions bit rates. showed strong correlations between obtained coding rates used, revealed a difference scores at home. As conclusion, it must underlined that are necessary comparative purposes, while experienced should under circumstances as close possible user’s environment.
