Abstract

Multimedia applications over 3G and 4G (third and fourth generation) networks will be based on digital encoding techniques (e.g., MPEG-4) that achieve high compression ratios by exploiting the spatial and temporal redundancy in video sequences. However, digital encoding causes image artifacts, which result in perceived-quality degradation. Due to the fact that the parameters with strong influence on the video quality are normally those set at the encoder (most importantly, the bit rate and resolution), the issue of user satisfaction in correlation with the encoding parameters has been raised (MPEG Test, 1999).
