Description

This database is a result of joint effort of Laboratoire Bordelais de Recherche en Informatique LaBRI (University of Bordeaux) and Communication Systems Engineering Dept. (Ben Gurion University of the Negev (BGU)). The database is composed of 15 video sources (SRC) from OpenVideo.org, TUM/Taurus Media and NTIA/ITS databases. The SRC videos were encoded in H.264/AVC with the x264 encoder at 6000kb/s. The resolution of the 15 SRC videos is 1920x1080 pixels progressive and the frame-rate is 25 frames per second. The 15 SRC videos were decoded with the FFMPEG 0.5.1 H.264/AVC decoder to produce YUV 4:2:0 raw file, presented to the subjects during the experiment. According to recommendation ITU-R BT500.11, the length of each video sequence is equal to 10 seconds (250 frames). Two network models, IP and RF, were applied on the 15 SRC. The IP model is composed of 5 different loss profiles which are defined in ITU-T G.1050. The RF model is composed of 3 loss different profiles. Thus (5 + 3) * 15 = 120 PVS sequences are present in this database. Subjective and objective metrics were computed on this video database. The metrics values for each SRC and PVS sequences are stored in a table available in Microsoft Excel and CSV file formats. Subjective metrics are MOS (Mean Opinion Score) and DMOS (Differential Mean Opinion Score). Objective metrics are PSNR and SSIM. The settings of each HRC are also available in a table in CSV format. Tables with the offsets of the first frame in the H.264 streams (tables of sections 1 and 2.2) are stored in file LaBRI-exp-offsets.csv.
