Information

Overview

This database contains 56 (28 QVGA and 28 VGA) videos sequences and the associated subjective results. 4 different video source contents were used in QVGA and the same 4 contents in VGA. For each content, the reference (without degradation) and 6 different degradations, in each format called Hypothetical Reference Circuits (HRCs) were subjectively evaluated.

All observers seen all videos in one session.

Each observer done only one session. So the observer number 1 in QVGA is not the same than in VGA session. 

We used SAMVIQ as test methodology.

Provided data

On the FTP server, we provide the videos in the directory "Videos". These videos are AVI files. After downloading, you can visualize the video by using a video player like VLC for example.

The subjective scores are provided. An Excel file is provided. In this Excel file, there are 2 spreadsheets : one for the QVGA experiment and one for the VGA experiment. In this file, a PVS (an AVI video) is associated to a line and an observer to a column. You have access to all individual vote from each observer to each AVI video. The last column is the Mean Opinion Score (MOS).
