Network-based packet loss visibility model for SDTV and HDTV for H.264 videos

We conduct subjective experiments on visual quality following packet loss, and then construct models to predict these visual importance scores. The models are fully self-contained at the packet level, meaning that they use only information within one packet to predict the importance of that packet, requiring no frame-level reconstruction nor any information on the reference frame. Models are created for SDTV and HDTV resolutions, and the differences in the important factors between them are discussed.
