Overview 

This database contains 87 videos sequences and the associated subjective results. 3 different video source contents were used. For each content, the reference (without degradation) and 28 different degradations called Hypothetical Reference Circuits (HRCs) were subjectively evaluated.

Provided data

On the FTP server, we provide the videos in the directory "Videos". These videos are AVI files. To reduce the downloading time duration, the avi files are zipped to bz2 files. To uncompress the files, use an archiver like IZArc. 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 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).

We used Absolute Category Rating (ACR) with 11 levels as test methodology. A text file describes the exact conditions in which the videos were evaluated.
