Free registration required

Executive Summary

The primary aim of this paper is to assess video quality for all content types as affected by Quality of Service (QoS) parameters both in the application and network level. Video streaming is a promising multimedia application and is gaining popularity over wireless/mobile communications. The quality of the video depends heavily on the type of content. The authors tested 12 different video clips reflecting different content types. They chose Peak-Signal-to-Noise-Ratio (PSNR) and decodable frame rate (Q) as end-to-end video quality metrics and MPEG4 as the video codec. From their experiments they found that video contents with high Spatio-Temporal (ST) activity are very sensitive to packet loss compared to those with low ST-activity.
