Abstract

Wireless networks typically suffer from packet loss and variable bit-rates due to bandwidth variations when, for example, video is transported between different devices in the home. Users who are watching video sent over wireless networks will therefore often experience jerkiness and blocking in the image. To intercept the effects caused by those problems, adaptation methods such as I-Frame Delay and Signal-to-Noise Ratio scalability were devised. To assess the perceived quality of MPEG-2 video optimized by these adaptation methods, subjective tests were carried out. These tests demonstrate, amongst others, that scene content and duration of the quality loss affects the perceived quality. Furthermore, we observed a saturation effect.
