Automation of Subjective Video Quality Measurements

Quality of Experience is utterly important in Communication Systems, especially in audiovisual services. Audio and video quality, as perceived by the users, is one of the most important aspects that affect the Quality of Experience. The most accurate methods for measuring the perceived audio and video quality of a video clip are the subjective tests, where the video sequences are presented to different viewers, and opinions are averaged. Subjective measurements are also necessary to develop and calibrate objective models for video quality estimation. Different methods for performing these tests are standardized, and normally require many manual setups, data-entry and/or special hardware devices. This paper presents the design, development and deployment of a software based system to automate the subjective tests for video quality measurement. The application is available for download and use for the academic community.
