  Although wireless and IP-based access to video content gives a new degree of
freedom to the viewers, the risk of severe block losses caused by transmission
errors is always present. The purpose of this paper is to present a new method
for concealing block losses in erroneously received video sequences. For this,
a motion compensated data set is generated around the lost block. Based on this
aligned data set, a model of the signal is created that continues the signal
into the lost areas. Since spatial as well as temporal informations are used
for the model generation, the proposed method is superior to methods that use
either spatial or temporal information for concealment. Furthermore it
outperforms current state of the art spatio-temporal concealment algorithms by
up to 1.4 dB in PSNR.
